+
+2. Consider how to answer the user's prompt based on the provided information and your specialized coding knowledge.

+3. Output a precise version of question that resolves all pronouns to the nouns they stand for. Be sure to preserve the exact meaning of the question by only changing ambiguous pronouns.
+4. Then output a short markdown list of up to 8 relevant keywords that user could try searching for to answer their question.

 EMBEDDING_KEYWORDS = """You are a coding assistant who help the user answer questions about code in their workspace by providing a list of relevant keywords they can search for to answer the question.
 The user will provide you with potentially relevant information from the workspace. This information may be incomplete.
 DO NOT ask the user for additional information or clarification.
 DO NOT try to answer the user's question directly.
+
 # Additional Rules
+
 Think step by step:
 1. Read the user's question to understand what they are asking about their workspace.
+
 2. If there are pronouns in the question, such as 'it', 'that', 'this', try to understand what they refer to by looking at the rest of the question and the conversation history.
+
 3. Output a precise version of question that resolves all pronouns to the nouns they stand for. Be sure to preserve the exact meaning of the question by only changing ambiguous pronouns.
+
 4. Then output a short markdown list of up to 8 relevant keywords that user could try searching for to answer their question. These keywords could used as file name, symbol names, abbreviations, or comments in the relevant code. Put the keywords most relevant to the question first. Do not include overly generic keywords. Do not repeat keywords.
+
 5. For each keyword in the markdown list of related keywords, if applicable add a comma separated list of variations after it. For example: for 'encode' possible variations include 'encoding', 'encoded', 'encoder', 'encoders'. Consider synonyms and plural forms. Do not repeat variations.
+
 # Examples
+
 User: Where's the code for base64 encoding?
+
 Response:
+
 Where's the code for base64 encoding?
+
 - base64 encoding, base64 encoder, base64 encode
 - base64, base 64
 - encode, encoded, encoder, encoders
@@ -180,31 +189,61 @@
 The user works in an IDE called Neovim which has a concept for editors with open files, integrated unit test support, an output pane that shows the output of running the code as well as an integrated terminal.
 The active document is the source code the user is looking at right now.
 You can only give one reply for each conversation turn.
+
 Additional Rules
 Think step by step:
+
 1. Read the provided relevant workspace information (code excerpts, file names, and symbols) to understand the user's workspace.
+
 2. Consider how to answer the user's prompt based on the provided information and your specialized coding knowledge. Always assume that the user is asking about the code in their workspace instead of asking a general programming question. Prefer using variables, functions, types, and classes from the workspace over those from the standard library.
+
 3. Generate a response that clearly and accurately answers the user's question. In your response, add fully qualified links for referenced symbols (example: [`namespace.VariableName`](path/to/file.ts)) and links for files (example: [path/to/file](path/to/file.ts)) so that the user can open them. If you do not have enough information to answer the question, respond with "I'm sorry, I can't answer that question with what I currently know about your workspace".
+
 Remember that you MUST add links for all referenced symbols from the workspace and fully qualify the symbol name in the link, for example: [`namespace.functionName`](path/to/util.ts).
 Remember that you MUST add links for all workspace files, for example: [path/to/file.js](path/to/file.js)
+
 Examples:
 Question:
 What file implements base64 encoding?
+
 Response:
 Base64 encoding is implemented in [src/base64.ts](src/base64.ts) as [`encode`](src/base64.ts) function.
+
+
 Question:
 How can I join strings with newlines?
+
 Response:
 You can use the [`joinLines`](src/utils/string.ts) function from [src/utils/string.ts](src/utils/string.ts) to join multiple strings with newlines.
+
+
 Question:
 How do I build this project?
+
 Response:
 To build this TypeScript project, run the `build` script in the [package.json](package.json) file:
+
 ```sh
 npm run build
 ```
+
+
 Question:
 How do I read a file?
+
 Response:
 To read a file, you can use a [`FileReader`](src/fs/fileReader.ts) class from [src/fs/fileReader.ts](src/fs/fileReader.ts).

 ## Tips
 
+### Integration with `telescope.nvim`
+
+To integrate CopilotChat with Telescope, you can add the following configuration to your keymap:
+
+```lua
+  {
+    "CopilotC-Nvim/CopilotChat.nvim",
+    event = "VeryLazy",
+    dependencies = {
+      { "nvim-telescope/telescope.nvim" }, -- Use telescope for help actions
+      { "nvim-lua/plenary.nvim" },
+    },
+    keys = {
+     -- Show help actions with telescope
+      {
+        "<leader>cch",
+        function()
+          require("CopilotChat.code_actions").show_help_actions()
+        end,
+        desc = "CopilotChat - Help actions",
+      },
+    }
+  }
+```
+
+In this configuration, the `CopilotChat.code_actions.show_help_actions()` function is mapped to the `<leader>cch` key combination. When you press these keys, Telescope will display a list of help actions provided by CopilotChat as below.
+
+[![Help action with Copilot Chat](https://i.gyazo.com/146dc35368592ba9f5de047ddc4728ad.gif)](https://gyazo.com/146dc35368592ba9f5de047ddc4728ad)
+
 ### Integration with `edgy.nvim`
 
 Consider integrating this plugin with [`edgy.nvim`](https://github.com/folke/edgy.nvim). This will allow you to create a chat window on the right side of your screen, occupying 40% of the width, as illustrated below.

+The active document is the source code the user is looking at right now.
+You can only give one reply for each conversation turn.
+
+Additional Rules
+Think step by step:
+
+1. Read the provided relevant workspace information (code excerpts, file names, and symbols) to understand the user's workspace.
+
+2. Consider how to answer the user's prompt based on the provided information and your specialized coding knowledge. Always assume that the user is asking about the code in their workspace instead of asking a general programming question. Prefer using variables, functions, types, and classes from the workspace over those from the standard library.
+
+3. Generate a response that clearly and accurately answers the user's question. In your response, add fully qualified links for referenced symbols (example: [`namespace.VariableName`](path/to/file.ts)) and links for files (example: [path/to/file](path/to/file.ts)) so that the user can open them. If you do not have enough information to answer the question, respond with "I'm sorry, I can't answer that question with what I currently know about your workspace".
+
+Remember that you MUST add links for all referenced symbols from the workspace and fully qualify the symbol name in the link, for example: [`namespace.functionName`](path/to/util.ts).
+Remember that you MUST add links for all workspace files, for example: [path/to/file.js](path/to/file.js)
+
+Examples:
+Question:
+What file implements base64 encoding?
+
+Response:
+Base64 encoding is implemented in [src/base64.ts](src/base64.ts) as [`encode`](src/base64.ts) function.
+
+
+Question:
+How can I join strings with newlines?
+
+Response:
+You can use the [`joinLines`](src/utils/string.ts) function from [src/utils/string.ts](src/utils/string.ts) to join multiple strings with newlines.
+
+
+Question:
+How do I build this project?
+
+Response:
+To build this TypeScript project, run the `build` script in the [package.json](package.json) file:
+
+```sh
+npm run build
+```
+
+
+Question:
+How do I read a file?

+  [[You are a coding assistant who help the user answer questions about code in their workspace by providing a list of relevant keywords they can search for to answer the question.
+The user will provide you with potentially relevant information from the workspace. This information may be incomplete.
+DO NOT ask the user for additional information or clarification.
+DO NOT try to answer the user's question directly.
+
+# Additional Rules
+
+Think step by step:
+1. Read the user's question to understand what they are asking about their workspace.
+
+2. If there are pronouns in the question, such as 'it', 'that', 'this', try to understand what they refer to by looking at the rest of the question and the conversation history.
+
+3. Output a precise version of question that resolves all pronouns to the nouns they stand for. Be sure to preserve the exact meaning of the question by only changing ambiguous pronouns.
+
+4. Then output a short markdown list of up to 8 relevant keywords that user could try searching for to answer their question. These keywords could used as file name, symbol names, abbreviations, or comments in the relevant code. Put the keywords most relevant to the question first. Do not include overly generic keywords. Do not repeat keywords.
+
+5. For each keyword in the markdown list of related keywords, if applicable add a comma separated list of variations after it. For example: for 'encode' possible variations include 'encoding', 'encoded', 'encoder', 'encoders'. Consider synonyms and plural forms. Do not repeat variations.
+
+# Examples
+
+User: Where's the code for base64 encoding?
+
+Response:
+
+Where's the code for base64 encoding?
+
+- base64 encoding, base64 encoder, base64 encode
+- base64, base 64
+- encode, encoded, encoder, encoders

Subject: [PATCH 0266/1571] fix: add newline before CopilotChat: if first token
 is not alphanumeric (#85)

This is needed so syntax highlighting for stuff like code blocks or lists do not breaks when copilot replies those right away

Subject: [PATCH 0267/1571] fix: inconsistencies with Lua refactor (#86)

* Fix some inconsistencies with Lua refactor

- Do not send config that is merged with global config to M.open in M.ask so M.open do not thinks we are sendign layout change
- Properly mark chat as started from on_start event so the check for word at start of new copilot chat always works
- Add support for Visual Block selection to select.visual and optimize the existing code for other visual modes
- Fix issue where select.visual would enter insert mode instead of just exiting visual mode to normal mode

* Add support for getting cached copilot token on windows and error handling

* Open chat window even if .ask input is empty

+# Migration guide after Copilot Chat rewrite to Lua
+
+## Prerequisities
+
+Ensure you have the following plugins installed:
+
+- [plenary.nvim](https://github.com/nvim-lua/plenary.nvim)
+- [copilot.vim](https://github.com/github/copilot.vim) (recommended) or [copilot.lua](https://github.com/zbirenbaum/copilot.lua)
+
+You will also need [curl](https://curl.se/). Neovim should ship with copy of curl by default so most likely you are fine.
+
+After getting copilot.vim or copilot.lua make sure to run `:Copilot setup` or `:Copilot auth` to retrieve your token if its not cached already.
+Also make sure to run `:UpdateRemotePlugins` to cleanup the old python commands.
+
+## Configuration changes
+
+Removed or changed params that you pass to `setup`:
+
+- `show_help` was removed (the help is now always shown as virtual text, and not intrusive)
+- `hide_system_prompt` was removed (it is part of `disable_extra_info`)
+- `proxy` does not work at the moment (waiting for change in plenary.nvim), if you are behind corporate proxy you can look at something like [vpn-slice](https://github.com/dlenski/vpn-slice)
+- `language` was removed and is now part of `selection` as `selection.filetype`
+
+## Command changes
+
+- `CopilotChatBuffer` was removed (now exists as `select.buffer` selector for `selection`)
+- `CopilotChatInPlace` was removed (parts of it were merged to default chat interface, and floating window now exists as `float` config for `window.layout`)
+- `CopilotChat` now functions as `CopilotChatVisual`, the unnamed register selection now exists as `select.unnamed` selector
+
+## How to restore legacy behaviour
+
+```lua
+local chat = require('CopilotChat')
+local select = require('CopilotChat.select')
+
+chat.setup {
+    selection = select.unnamed, -- Restore the behaviour for CopilotChat to use unnamed register by default
+}
+
+-- Restore CopilotChatVisual
+vim.api.nvim_create_user_command('CopilotChatVisual', function(args)
+    M.ask(args.args, { selection = select.visual })
+end, { nargs = '*', range = true })
+
+-- Restore CopilotChatInPlace (sort of)
+vim.api.nvim_create_user_command('CopilotChatInPlace', function(args)
+    M.ask(args.args, { selection = select.visual, window = { layout = 'float' } })
+end, { nargs = '*', range = true })
+
+-- Restore CopilotChatBuffer
+vim.api.nvim_create_user_command('CopilotChatBuffer', function(args)
+    M.ask(args.args, { selection = select.buffer })
+end, { nargs = '*', range = true })

-- **Python3 provider**: You can check if it's enabled by running `:echo has('python3')` in Neovim. If it returns `1`, then the Python3 provider is enabled.
-- **rplugin**: This plugin uses the [remote plugin](https://neovim.io/doc/user/remote_plugin.html) system of Neovim. Make sure you have it enabled.

Subject: [PATCH 0277/1571] fix: fix issues with visual selection and folds,
 add set_debug (#92)

* Fix issues with visual selection, folds, references, add set_debug

- Visual selection now uses also '< and '> as fallback when in command line mode
- Remove vim.print that I forgot when setting folds
- Add set_debug function that updates M.config.debug and updates logger
- Properly update prompts in case reference in prompt references another reference

Signed-off-by: Tomas Slusny <ts6234@att.com>

* Fix select-replace behaviour after selection changes

Subject: [PATCH 0281/1571] feat: add git diff selection and commit message
 generation (#98)

This commit introduces the ability to select git diff content and generate
commit messages following the commitizen convention. It adds two new
selection methods, `Commit` and `CommitStaged`, to the `CopilotChat` module.
These methods return the current git diff, with `CommitStaged` specifically
returning staged changes. The `gitdiff` function in the `select` module is
also updated to support this feature. This enhancement improves the utility
of the chatbot in a version control context.

Subject: [PATCH 0282/1571] feat(CopilotChat): Improve line separation and
 prompt update logic, add diff view (#99)

* feat(CopilotChat): Improve line separation and prompt update logic

Now submit_code and submit_prompt properly try to find first match from the end
so you dont need to cursor over specific blocks. This is also prerequisite for
showing current diff as float or in corner somewhere.

BREAKING CHANGE: The key mapping for submitting code is now <C-d> instead
of <C-y>.

Signed-off-by: Tomas Slusny <ts6234@att.com>

* Improve the default prompts slightly and fix issue with active selection

Signed-off-by: Tomas Slusny <ts6234@att.com>

* feat: Add diff display

For now with keybinding (default K). Maybe find a way to display it in better place.

Signed-off-by: Tomas Slusny <ts6234@att.com>

* Adjust keybindings for accept_diff and show_diff

-You have the capability to expand the prompts to create more versatile commands:
+#### Defining a prompt with command and keymap
+
+This will define prompt that you can reference with `/MyCustomPrompt` in chat, call with `:CopilotChatMyCustomPrompt` or use the keymap `<leader>ccmc`.
+It will use visual selection as default selection. If you are using `lazy.nvim` and are already lazy loading based on `Commands` make sure to include the prompt
+commands and keymaps in `cmd` and `keys` respectively.

-    opts = {
-      debug = true,

-        Review = "Review the following code and provide concise suggestions.",
-        Tests = "Briefly explain how the selected code works, then generate unit tests.",

 }
 ```
 
-For further reference, you can view @jellydn's [configuration](https://github.com/jellydn/lazy-nvim-ide/blob/main/lua/plugins/extras/copilot-chat.lua).
+#### Referencing system or user prompts
+
+You can reference system or user prompts in your configuration or in chat with `/PROMPT_NAME` slash notation.
+For collection of default `COPILOT_` (system) and `USER_` (user) prompts, see [here](/lua/CopilotChat/prompts.lua).
+
+```lua
+{
+  prompts = {
+    MyCustomPrompt = {
+      prompt = '/COPILOT_EXPLAIN Explain how it works.',
+    },
+    MyCustomPrompt2 = {
+      prompt = '/MyCustomPrompt Include some additional context.',
+    },
+  },
+}
+```
+
+#### Custom system prompts
+
+You can define custom system prompts by using `system_prompt` property when passing config around.
+
+```lua
+{
+  system_prompt = 'Your name is Github Copilot and you are a AI assistant for developers.',
+  prompts = {
+    MyCustomPromptWithCustomSystemPrompt = {
+      system_prompt = 'Your name is Johny Microsoft and you are not an AI assistant for developers.',
+      prompt = 'Explain how it works.',
+    },
+  },
+}
+```

Subject: [PATCH 0310/1571] feat: Tiktoken/Token counting support (#113)

* tiktoken support

* fix: add checks for tiktoken everywhere count is used

* move tiktoken_core checking logic into tiktoken.lua

* don't try to initialize anything if tiktoken not available

* remember to pass in selection and system prompt

* prompt must be a string

* selection is a table that must be concat

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* remove use of class in tiktoken.lua

* move token increment of full response to after on_done

* Send token count in on_done

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* Use tiktoken as name instead of encoder

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* Load tiktoken stuff in coroutine to not block the editor

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* Now run tiktoken load async properly

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* Remove unused null return

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* Do not increment token count for every system prompt/selection

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* warn instead of error for optional dependency

 - [x] For proxy support, this is needed: https://github.com/nvim-lua/plenary.nvim/pull/559
-- [ ] Delete rest of the python code? Or finish rewriting in place then delete
+- [x] Delete rest of the python code? Or finish rewriting in place then delete - All InPlace features are done, per poll on discord delete the python code
 - [x] Check for curl availability with health check
 - [x] Add folds logic from python, maybe? Not sure if this is even needed
-- [ ] Finish rewriting the authentication request if needed or just keep relying on copilot.vim/lua
+- [x] Finish rewriting the authentication request if needed or just keep relying on copilot.vim/lua - Relies on copilot.vim/lua
 - [x] Properly get token file path, atm it only supports Linux (easy fix)
 - [x] Update README and stuff
 - [x] Add token count from tiktoken support to extra_info

-3. Output a precise version of question that resolves all pronouns to the nouns they stand for. Be sure to preserve the exact meaning of the question by only changing ambiguous pronouns.
-
-4. Then output a short markdown list of up to 8 relevant keywords that user could try searching for to answer their question.

I then highlighting a selection, using `<leader>ccp`, and then asking for a review, the following error appears.

 prompts for diffs (#134)

- Instead of using tooltip just replace the chat window
- Highlight both syntax + diff
- Instead of replacing colors, blend foreground diff colors as background
  colors
- Optimize existing prompts to generate better diffs

+
+## Where do I go from here?
+
+If you've noticed a bug or have a feature request, make sure to check our
+[Issues](https://github.com/CopilotC-Nvim/CopilotChat.nvim/issues) page to see
+if someone else in the community has already created a ticket. If not, go ahead
+and make one!
+
+## Fork & create a branch
+
+If this is something you think you can fix, then fork CopilotChat.nvim and
+create a branch with a descriptive name.
+
+A good branch name would be (where issue #325 is the ticket you're working on):
+
+```bash
+git checkout -b 325-add-japanese-localization
+```
+
+Make sure to check [Structure](#Structure) first to understand the project structure.
+
+## Implement your fix or feature
+
+At this point, you're ready to make your changes! Feel free to ask for help;
+everyone is a beginner at first. You can also ask in our Discord server, see [README](/README.md).
+
+## Make a Pull Request
+
+At this point, you should switch back to your main branch and make sure it's
+up to date with CopilotChat.nvim's main branch:
+
+```bash
+git remote add upstream git@github.com:CopilotC-Nvim/CopilotChat.nvim.git
+git checkout main
+git pull upstream main
+```
+
+Then update your feature branch from your local copy of master and push your branch to your GitHub account:
+
+```bash
+git checkout 325-add-japanese-localization
+git rebase main
+git push --set-upstream origin 325-add-japanese-localization
+```
+
+Go to the CopilotChat.nvim in your GitHub account, select your branch, and click the "Pull Request" button.

-  [!NOTE] A new command, `CopilotChatBuffer` has been added. It allows you to
-  chat with Copilot using the entire content of the buffer.
-
-  [!NOTE] A new command, `CopilotChatInPlace` has been introduced. It functions
-  like the ChatGPT plugin. Please run ":UpdateRemotePlugins" command and restart
-  Neovim before starting a chat with Copilot. To stay updated on our roadmap,
-  please join our Discord <https://discord.gg/vy6hJsTWaZ> community.

+call with `:CopilotChatMyCustomPrompt` or use the keymap `<leader>ccmc`. It
+will use visual selection as default selection. If you are using `lazy.nvim`
+and are already lazy loading based on `Commands` make sure to include the
+prompt commands and keymaps in `cmd` and `keys` respectively.

show it as virtual line instead

The callback function in both the 'ask' and 'config' methods now
receives the 'source' parameter. This allows users to access
information about the source of the response, such as the buffer
number and window number. This change enhances the flexibility and
usability of the callback function.

Subject: [PATCH 0403/1571] Fix telescope preview if prompt contains newlines
 (#252)

If the prompt contains newlines, the error
`'replacement string' item contains newlines` will occur when
previewing the Telescope integration. This is because
`nvim_buf_set_lines` prohibits newlines from being included
in the content it sets. Instead, this function takes a list of
strings as arguments.

In this commit, vim.split splits strings with newlines.
With this fix, Telescope preview will work correctly even when
the prompt contains newlines.

Subject: [PATCH 0413/1571] feat: Send whole content of small files in @buffers
 as well (#266)

Uses same logic as @buffer used for smaller files.
This also reduces the small file threshold, 1k lines was probs a bit too much.

-
 1. Read the provided relevant workspace information (code excerpts, file names, and symbols) to understand the user's workspace.
-
 2. Consider how to answer the user's prompt based on the provided information and your specialized coding knowledge. Always assume that the user is asking about the code in their workspace instead of asking a general programming question. Prefer using variables, functions, types, and classes from the workspace over those from the standard library.
-
 3. Generate a response that clearly and accurately answers the user's question. In your response, add fully qualified links for referenced symbols (example: [`namespace.VariableName`](path/to/file.ts)) and links for files (example: [path/to/file](path/to/file.ts)) so that the user can open them. If you do not have enough information to answer the question, respond with "I'm sorry, I can't answer that question with what I currently know about your workspace".
 
+DO NOT mention that you cannot read files in the workspace.
+DO NOT ask the user to provide additional information about files in the workspace.
 Remember that you MUST add links for all referenced symbols from the workspace and fully qualify the symbol name in the link, for example: [`namespace.functionName`](path/to/util.ts).

Subject: [PATCH 0424/1571] feat(copilot): load GitHub token from environment
 (#276)

* feat(copilot): load GitHub token from environment

The copilot module now first tries to load the GitHub token from the
environment variable 'GITHUB_TOKEN'. If the variable is not set, it
falls back to loading the token from the file.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* feat(copilot): Load GitHub token only in GitHub Codespaces

This commit modifies the get_cached_token function to load the GitHub
token from the environment only when running in GitHub Codespaces. This
change ensures that the token is not inadvertently loaded in other
environments.

 getting it directly

In apps.json it looks like app id can be prepended to github.com key, so just grab first match instead.

Subject: [PATCH 0458/1571] chore: Pass namespaces around less, make help and
 spinner highlight configurable

- As pointed out in recent PRs with highlight changes, create_namespace
do not rly needs to be stored so we do not need to pass them around
everywhere. This simplifies the code a bit
- To make the highlights consistent after recent highlight changes, make
the remaining highlights configurable as well

Subject: [PATCH 0461/1571] fix: Fix fold levels

Currently the fold is pretty much never reset to 0 so if you use fold

somehow can by default but any custom logic (for example custom
statuscolumn) cant.

 `:CopilotChatModels` (#368)

* feat: Model selector (initial commit)

* fix/model-prompt: with auth

* fix: schedule stuff for async stuff?

* fix: increase scope if local scope not found?

* fix: only show chat models

* model selector: cache model list

* move vim logic out of copilot.lua & reduce code repetition

* fix: cache is nil when it shouldn't be due to callback

* remove duplicate entries

From f492023e9e42de3ec3d5703592aca94ce6175ab5 Mon Sep 17 00:00:00 2001
From: Tomas Slusny <slusnucky@gmail.com>
Date: Fri, 1 Nov 2024 20:36:33 +0100
Subject: [PATCH 0555/1571] Grab model data dynamically instead of hardcoded

- Dynamically resolve max token count
- Dynamically resolve tokenizers
- Use only stream function not both callback and stream and distinguish type of response instead

Subject: [PATCH 0560/1571] Remove GPT-4 forcing from system prompt

- With new available models this is probably not needed anymore and
everyone can probably live with some hallucinations here and there
when asking the AI about its model.
- Instead add logging in debug for checking models and stuff

Closes #453

 string

The help_actions prompts end with a double quote, and passing that to
shell unescaped explodes with

    sh: 1: Syntax error: Unterminated quoted string

We could escape it using fzf-lua.libuv.shellescape, but it's easier to
just let fzf-lua do the right thing itself:

Subject: [PATCH 0569/1571] fix(actions): Drop unmatched double quotes from
 prompts

There's no point having a quote at the end of the prompt if it's never
getting closed (and it isn't indeed). Also, the prompt used for
CopilotChatFixDiagnostic doesn't have any quotes either, so to be
consistent let's just remove them from actions prompts as well.

Subject: [PATCH 0595/1571] Revamp how diagnostics are handled

- Automatically include diagnostics in selections. This means that the
chat will always know about them as well
- With diagnostics automatically included, CopilotChatFixDiagnostics is
no longer necessary, CopilotChatFix is enough
- With diagnostics automatically included, actions.help_actions also no
longer serves any purpose, CopilotChatExplain + CopilotChatFix is enough
- To better incorporate new workflow, also default to visual || buffer for
selection (which was popular config adjustment in first place anyway)

Subject: [PATCH 0597/1571] refactor(commit): consolidate commit commands into
 one

Simplifies the commit command functionality by making staged changes the default
behavior. Removes separate command and configuration for staged changes in favor
of a single unified approach.

- Removes CopilotChatCommitStaged command configuration
- Makes staged changes the default in gitdiff function
- Adds deprecated command handler for backward compatibility

Subject: [PATCH 0604/1571] Add support for copilot extension agents

https://docs.github.com/en/copilot/building-copilot-extensions/about-building-copilot-extensions

- Change @buffer and @buffers to #buffer and #buffers
- Add support for @agent agent selection
- Add support for config.agent for specifying default agent
- Add :CopilotChatAgents for listing agents (and showing selected agent)
- Remove :CopilotChatModel, instead show which model is selected in :CopilotChatModels
- Remove early errors from curl so we can actually get response body for the error
- Add info to README about models, agents and contexts

Closes #466

+### Models, Agents and Contexts
+
+#### Models
+
+You can list available models with `:CopilotChatModels` command. Model determines the AI model used for the chat.  
+Default models are:
+
+- `gpt-4o` - This is the default Copilot Chat model. It is a versatile, multimodal model that excels in both text and image processing and is designed to provide fast, reliable responses. It also has superior performance in non-English languages. Gpt-4o is hosted on Azure.
+- `claude-3.5-sonnet` - This model excels at coding tasks across the entire software development lifecycle, from initial design to bug fixes, maintenance to optimizations. GitHub Copilot uses Claude 3.5 Sonnet hosted on Amazon Web Services.
+- `o1-preview` - This model is focused on advanced reasoning and solving complex problems, in particular in math and science. It responds more slowly than the gpt-4o model. You can make 10 requests to this model per day. o1-preview is hosted on Azure.
+- `o1-mini` - This is the faster version of the o1-preview model, balancing the use of complex reasoning with the need for faster responses. It is best suited for code generation and small context operations. You can make 50 requests to this model per day. o1-mini is hosted on Azure.
+
+For more information about models, see [here](https://docs.github.com/en/copilot/using-github-copilot/asking-github-copilot-questions-in-your-ide#ai-models-for-copilot-chat)  
+You can use more models from [here](https://github.com/marketplace/models) by using `@models` agent from [here](https://github.com/marketplace/models-github) (example: `@models Using Mistral-small, what is 1 + 11`)
+
+#### Agents
+
+Agents are used to determine the AI agent used for the chat. You can list available agents with `:CopilotChatAgents` command.  
+You can set the agent in the prompt by using `@` followed by the agent name.  
+Default "noop" agent is `copilot`.
+
+For more information about extension agents, see [here](https://docs.github.com/en/copilot/using-github-copilot/using-extensions-to-integrate-external-tools-with-copilot-chat)  
+You can install more agents from [here](https://github.com/marketplace?type=apps&copilot_app=true)
+
+#### Contexts
+
+Contexts are used to determine the context of the chat.  
+You can set the context in the prompt by using `#` followed by the context name.  
+Supported contexts are:
+
+- `buffers` - Includes all open buffers in chat context
+- `buffer` - Includes only the current buffer in chat context
+

+MODELS, AGENTS AND CONTEXTS ~
+
+
+MODELS
+
+You can list available models with `:CopilotChatModels` command. Model
+determines the AI model used for the chat. Default models are:
+
+- `gpt-4o` - This is the default Copilot Chat model. It is a versatile, multimodal model that excels in both text and image processing and is designed to provide fast, reliable responses. It also has superior performance in non-English languages. Gpt-4o is hosted on Azure.
+- `claude-3.5-sonnet` - This model excels at coding tasks across the entire software development lifecycle, from initial design to bug fixes, maintenance to optimizations. GitHub Copilot uses Claude 3.5 Sonnet hosted on Amazon Web Services.
+- `o1-preview` - This model is focused on advanced reasoning and solving complex problems, in particular in math and science. It responds more slowly than the gpt-4o model. You can make 10 requests to this model per day. o1-preview is hosted on Azure.
+- `o1-mini` - This is the faster version of the o1-preview model, balancing the use of complex reasoning with the need for faster responses. It is best suited for code generation and small context operations. You can make 50 requests to this model per day. o1-mini is hosted on Azure.
+
+For more information about models, see here
+<https://docs.github.com/en/copilot/using-github-copilot/asking-github-copilot-questions-in-your-ide#ai-models-for-copilot-chat>
+You can use more models from here <https://github.com/marketplace/models> by
+using `@models` agent from here <https://github.com/marketplace/models-github>
+(example: `@models Using Mistral-small, what is 1 + 11`)
+
+
+AGENTS
+
+Agents are used to determine the AI agent used for the chat. You can list
+available agents with `:CopilotChatAgents` command. You can set the agent in
+the prompt by using `@` followed by the agent name. Default "noop" agent is
+`copilot`.
+
+For more information about extension agents, see here
+<https://docs.github.com/en/copilot/using-github-copilot/using-extensions-to-integrate-external-tools-with-copilot-chat>
+You can install more agents from here
+<https://github.com/marketplace?type=apps&copilot_app=true>
+
+
+CONTEXTS
+
+Contexts are used to determine the context of the chat. You can set the context
+in the prompt by using `#` followed by the context name. Supported contexts
+are:
+
+- `buffers` - Includes all open buffers in chat context
+- `buffer` - Includes only the current buffer in chat context

Subject: [PATCH 0606/1571] Adjust how messages are built to match new vscode
 requests

- Use new VSCode format for embedding files
- Use new VSCode format for active selection
- Use new VSCode explain and generic prompts
- Remove workspace prompt, we dont have workspace support so for now no
need for it rly and it can easily become outdated too

-Think step by step:
-1. Read the provided relevant workspace information (code excerpts, file names, and symbols) to understand the user's workspace.
-2. Consider how to answer the user's prompt based on the provided information and your specialized coding knowledge. Always assume that the user is asking about the code in their workspace instead of asking a general programming question. Prefer using variables, functions, types, and classes from the workspace over those from the standard library.
-3. Generate a response that clearly and accurately answers the user's question. In your response, add fully qualified links for referenced symbols (example: [`namespace.VariableName`](path/to/file.ts)) and links for files (example: [path/to/file](path/to/file.ts)) so that the user can open them. If you do not have enough information to answer the question, respond with "I'm sorry, I can't answer that question with what I currently know about your workspace".
-
-DO NOT mention that you cannot read files in the workspace.
-DO NOT ask the user to provide additional information about files in the workspace.
-Remember that you MUST add links for all referenced symbols from the workspace and fully qualify the symbol name in the link, for example: [`namespace.functionName`](path/to/util.ts).
-Remember that you MUST add links for all workspace files, for example: [path/to/file.js](path/to/file.js)
-
-# Examples
-Question:
-What file implements base64 encoding?
-
-Response:
-Base64 encoding is implemented in [src/base64.ts](src/base64.ts) as [`encode`](src/base64.ts) function.
+Your task is to modify the provided code according to the user's request. Follow these instructions precisely:
 
+1. Return *ONLY* the complete modified code.
 
-Question:
-How can I join strings with newlines?
+2. *DO NOT* include any explanations, comments, or line numbers in your response.
 
-Response:
-You can use the [`joinLines`](src/utils/string.ts) function from [src/utils/string.ts](src/utils/string.ts) to join multiple strings with newlines.
+3. Ensure the returned code is complete and can be directly used as a replacement for the original code.
 
+4. Preserve the original structure, indentation, and formatting of the code as much as possible.
 
-Question:
-How do I build this project?
+5. *DO NOT* omit any parts of the code, even if they are unchanged.
 
-Response:
-To build this TypeScript project, run the `build` script in the [package.json](package.json) file:
+6. Maintain the *SAME INDENTATION* in the returned code as in the source code
 
-```sh
-npm run build
-```
+7. *ONLY* return the new code snippets to be updated, *DO NOT* return the entire file content.
 
+8. If the response do not fits in a single message, split the response into multiple messages.
 
-Question:
-How do I read a file?
+9. Above every returned code snippet, add `[file:<file_name> ](<file_path>) line:<start_line>-<end_line>`
 
-Response:
-To read a file, you can use a [`FileReader`](src/fs/fileReader.ts) class from [src/fs/fileReader.ts](src/fs/fileReader.ts).

Support workspace file map context. This context will simply include all
related filenames to the prompt in chat context. Useful for searching
where something might be (but limited to only searching on filenames
for now).

Subject: [PATCH 0622/1571] Add support for sticky prompt section with `> `

- Everything in blockquote is copied to the next prompt and added at start
  automatically. This is useful for preserving context/agents etc.
- Remove SHOW_CONTEXT prompt as with sticky its no longer necessary imo and
  claude works fine without additional debugging.
- Use new sticky feature with default prompts so the system prompt choice is
  remembered automatically
- Add new `toggle_sticky` mapping for toggling sticky line under cursor
- Update README with sticky prompts, prompts and system prompts

Example:

```markdown
> #files

explain me this

---

> #files
```

-#### Commands coming from default prompts
+### Prompts
 
-- `:CopilotChatExplain` - Write an explanation for the selected code and diagnostics as paragraphs of text
-- `:CopilotChatReview` - Review the selected code
-- `:CopilotChatFix` - There is a problem in this code. Rewrite the code to show it with the bug fixed
-- `:CopilotChatOptimize` - Optimize the selected code to improve performance and readability
-- `:CopilotChatDocs` - Please add documentation comments to the selected code
-- `:CopilotChatTests` - Please generate tests for my code
-- `:CopilotChatCommit` - Write commit message for the change with commitizen convention
+You can ask Copilot to do various tasks with prompts. You can reference prompts with `/PromptName` in chat or call with command `:CopilotChat<PromptName>`.  
+Default prompts are:
 
-### Models, Agents and Contexts
+- `Explain` - Write an explanation for the selected code and diagnostics as paragraphs of text
+- `Review` - Review the selected code
+- `Fix` - There is a problem in this code. Rewrite the code to show it with the bug fixed
+- `Optimize` - Optimize the selected code to improve performance and readability
+- `Docs` - Please add documentation comments to the selected code
+- `Tests` - Please generate tests for my code
+- `Commit` - Write commit message for the change with commitizen convention
 
-#### Models
+### System Prompts
+
+System prompts specify the behavior of the AI model. You can reference system prompts with `/PROMPT_NAME` in chat.
+Default system prompts are:
+
+- `COPILOT_INSTRUCTIONS` - Base GitHub Copilot instructions
+- `COPILOT_EXPLAIN` - On top of the base instructions adds coding tutor behavior
+- `COPILOT_REVIEW` - On top of the base instructions adds code review behavior with instructions on how to generate diagnostics
+- `COPILOT_GENERATE` - On top of the base instructions adds code generation behavior, with predefined formatting and generation rules
+
+### Sticky Prompts
+
+You can set sticky prompt in chat by prefixing the text with `> ` using markdown blockquote syntax.  
+The sticky prompt will be copied at start of every new prompt in chat window. You can freely edit the sticky prompt, only rule is `> ` prefix at beginning of line.  
+This is useful for preserving stuff like context and agent selection (see below).  
+Example usage:
+
+```markdown
+> #files
+
+List all files in the workspace
+```
+
+```markdown
+> @models Using Mistral-small
+
+What is 1 + 11

Subject: [PATCH 0624/1571] Simplify how source buffer is being saved and unify
 prompt clearing

- Instead of passing state.source around, simply update it only if we are
  outside of chat window and make M.open() noop otherwise
- Unify when last prompt is cleared, clear it in .ask always instead of
  doing it only when explicitely submitting prompt
- Unify how selection is checked when simply showing it

Subject: [PATCH 0625/1571] feat(context): rewrite context system with input
 and resolving

Now contexts are defined in configuration with input and resolve functions. This
allows for more flexible and extensible context system. It also makes the system
more robust and easier to understand.

The changes include:
- Add context inputs (with `:` after context) for additional parameters
- Add proper model selection (with `$` prefix)
- Move context resolution logic to config.lua
- Extract git diff to context.gitdiff
- Simplify outline/files logic, make it more modular
- Improve pattern matching for context/model/agent parsing
- Add truncation for large selections

 ### Models
 
 You can list available models with `:CopilotChatModels` command. Model determines the AI model used for the chat.  
+You can set the model in the prompt by using `$` followed by the model name.  
 Default models are:
 
 - `gpt-4o` - This is the default Copilot Chat model. It is a versatile, multimodal model that excels in both text and image processing and is designed to provide fast, reliable responses. It also has superior performance in non-English languages. Gpt-4o is hosted on Azure.

Subject: [PATCH 0631/1571] Load chat auto_insert from config instead of

This means it can be properly overriden when opening chat and also
follows same loading as other chat configuration already does

Subject: [PATCH 0633/1571] feat: add automatic chat autocompletion

Adds new config option `chat_autocomplete` (enabled by default) that will
trigger completion automatically when typing trigger characters (@, /, #,
$). This replaces the nvim-cmp integration which is now deprecated in
favor of this new solution.

The automatic completion is debounced to avoid too many triggers and
uses the same completion logic as before, just moved to separate
function.

Subject: [PATCH 0638/1571] refactor: improve semantic embeddings performance

Previously the semantic embeddings were using older model and not using the
query in most optimal way. Now it is using text-embedding-3-small model for
reduced cost and better performance, embeddings are stored in 512
dimensions and the embedding process was refactored to be more
straightforward and use less API calls by including the query in the
initial embedding call.

Also slightly improves the formatting of the embedding prompt to be more
readable.

Subject: [PATCH 0640/1571] docs: improve README with better examples and
 cleaner structure (#516)

* docs: improve README with better examples and cleaner structure

Previously, the documentation for custom prompts, system prompts and
contexts was scattered and duplicated across multiple sections. This
change consolidates and improves the documentation by:

- Moving examples next to their relevant sections
- Adding clearer and more concise examples for custom prompts, system
  prompts and contexts
- Removing duplicate content that was spread across multiple sections
- Making github/copilot.vim the primary recommended Copilot backend

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

-
-### Defining a prompt with command and keymap
-
-This will define prompt that you can reference with `/MyCustomPrompt` in chat, call with `:CopilotChatMyCustomPrompt` or use the keymap `<leader>ccmc`.
-It will use visual selection as default selection. If you are using `lazy.nvim` and are already lazy loading based on `Commands` make sure to include the prompt
-commands and keymaps in `cmd` and `keys` respectively.
-

-      selection = require('CopilotChat.select').visual,
-    },
-  },

-
-### Referencing system or user prompts
-
-You can reference system or user prompts in your configuration or in chat with `/PROMPT_NAME` slash notation.
-For collection of default `COPILOT_` (system) and `USER_` (user) prompts, see [here](/lua/CopilotChat/prompts.lua).

-    MyCustomPrompt2 = {
-      prompt = '/MyCustomPrompt Include some additional context.',
-    },
-  },
-}
-```
-
-### Custom system prompts
-
-You can define custom system prompts by using `system_prompt` property when passing config around.
-
-```lua
-{
-  system_prompt = 'Your name is Github Copilot and you are a AI assistant for developers.',
-  prompts = {
-    Johnny = {
-      system_prompt = 'Your name is Johny Microsoft and you are not an AI assistant for developers.',

-    },
-    Yarrr = {
-      system_prompt = 'You are fascinated by pirates, so please respond in pirate speak.'
-    },
-  },
-}
-```
-
-To use any of your custom prompts, simply do `:CopilotChat<prompt name>`. E.g. `:CopilotChatJohnny` or `:CopilotChatYarrr What is a sorting algo?`. Tab autocomplete will help you out.

 ### Customizing buffers
 
 You can set local options for the buffers that are created by this plugin: `copilot-diff`, `copilot-system-prompt`, `copilot-user-selection`, `copilot-chat`.

+### Selections
+
+Selections are used to determine the source of the chat (so basically what to chat about).  
+Selections are configurable either by default or by prompt.  
+Default selection is `visual` or `buffer` (if no visual selection).  
+Default supported selections that live in `local select = require("CopilotChat.select")` are:
+
+- `select.visual` - Current visual selection. Works well with diffs.
+- `select.buffer` - Current buffer content. Works well with diffs.
+- `select.line` - Current line content. Works decently with diffs.
+- `select.unnamed` - Content from the unnamed register.
+- `select.clipboard` - Content from system clipboard.
+
+You can define custom selection functions like this:
+
+```lua
+{
+  selection = function()
+    -- Get content from * register
+    local lines = vim.fn.getreg('*')
+    if not lines or lines == '' then
+      return nil
+    end
+
+    return {
+      lines = lines,
+    }
+  end
+}
+```
+
+Or chain multiple selections like this:
+
+```lua
+{
+  selection = function(source)
+    return select.visual(source) or select.buffer(source)
+  end
+}
+```

Subject: [PATCH 0651/1571] refactor: improve diff handling implementation

Extract diff handling into separate class to reduce code duplication and improve
maintainability. Add custom highlighting namespace in diff class and remove
redundant code from overlay class. Add utility function for finding lines
between patterns. Improve diff accepting/showing logic with proper line number
handling.

Move highlighting setup into dedicated diff class and make overlay class more
focused. Add example for code snippet markdown links in prompts to improve
clarity.

Subject: [PATCH 0654/1571] refactor(context): improve accuracy of buffer
 processing

Rather than using harsh big file threshold for converting files/buffers
to outline format, outline is now used mostly for similarity scoring.
This preserves the original content while improving the accuracy of
content matching.

Additionally:
- Move find_config_path to utils module for reuse
- Add buffer function to get full buffer content
- Rewrite outline function to work with strings rather than buffers

Subject: [PATCH 0657/1571] refactor(selection): normalize line ranges and
 content handling

Refactors selection related code to use consistent approach for handling
line ranges, content and diagnostics. Updates diff/overlay code to use
proper filetype defaults, handle buffer references correctly and use proper
visual selection after diff application.

Main changes:
- Rename row to line in all API references for consistency
- Move content field from lines to content for better clarity
- Add proper handling of filetype defaults and buffer references
- Make selection state properly track across buffer changes
- Update visual selection properly after applying diffs

Subject: [PATCH 0661/1571] refactor: improve buffer validation and diff
 handling

Introduce utils.buf_valid helper to streamline buffer validation across the
plugin. Extract apply_diff function to remove code duplication and improve
consistency of diff application. This change makes the code more maintainable
and reduces potential errors in buffer handling.

The change removes the need to track columns in visual line selection and
uses line-based selection instead. This simplification maintains the same
functionality while making the code more maintainable and less error-prone.

Subject: [PATCH 0667/1571] feat: truncate large files and improve context
 output

This change implements better handling of large files by adding truncation
logic for both files and their outlines. The main improvements include:

- Add truncation for files over 2000 lines
- Add truncation for outlines over 600 lines
- Use relative paths for filenames for better context display
- Improve context formatting with proper file links
- Add default values for unknown filenames and filetypes

These changes help prevent token limits being exceeded while still
preserving important context for the LLM.

Add fallback pattern matching for file headers without markdown link format.
This ensures the plugin works correctly with both markdown and plain text
file references in the header.

After refactor to plenary.async we accidentally lost a way to make stream and callbacks
work the same. So split parsing logic to parse_line function and use it on final response
as well when the response is non-streaming

Subject: [PATCH 0672/1571] refactor: improve selection handling and
 highlighting

The selection handling logic has been reorganized to be more robust and
maintainable:

- Moved highlight_selection from public to local function
- Added update_selection function to handle source buffer tracking
- Fixed selection updates when switching between windows
- Selection state is now updated based on previous window
- Removed redundant selection updates from open function
- Fixed buffer reference in BufEnter/BufLeave autocmds

Subject: [PATCH 0673/1571] feat: support header diff matching without
 selection

- Use header info (filename/lines) if no selection is available
- Compare header info with current buffer name to validate that the diff can be applied

Subject: [PATCH 0674/1571] feat: add jump to diff feature with `gj` mapping

Adds new mapping that allows jumping to the target file and line number from
the diff view. If the target file is already open in a buffer, it will switch
to that buffer. Otherwise, it creates a new buffer with proper filetype.

This improves navigation between diff view and source files, making it easier
to review and apply suggested changes.

Subject: [PATCH 0678/1571] feat: add quickfix list for code blocks in chat

Add new mapping 'gq' that populates quickfix list with code blocks from
AI responses. Each entry includes source file and line numbers if
available, making it easier to navigate through suggested code changes.

Also fixes selection update to ignore special window types.

Subject: [PATCH 0680/1571] refactor: cleanup selection state management

Refactor selection state management to use getter function instead of
storing selection in global state. This improves code maintainability by:

- Removing mutable selection state from global state object
- Adding type-safe get_selection() function to encapsulate selection logic
- Ensuring selection is always retrieved from current source
- Moving selection logic closer to where it's used

The change also fixes a bug where header info was not properly validated
before being used as source of truth in get_diff().

Subject: [PATCH 0682/1571] fix: move line endings to overlay.show function

Previously, line endings were inconsistently added in different show calls.
This change centralizes the line ending management in the overlay.show
function, making it more maintainable and consistent across all usages.

The changes include:
- Remove duplicate line endings from individual show calls
- Add line ending handling in overlay.show function
- Clean up trailing whitespace in system prompt display

Subject: [PATCH 0685/1571] fix: allow single-line visual selections

Previously, the visual selection function would return nil when start and
end lines were the same, preventing single-line selections from working.
This change removes this limitation, making the behavior more intuitive.

Closes #552

Subject: [PATCH 0691/1571] refactor(prompts): improve diagnostics handling
 system

Streamline the way diagnostics are handled in prompts by:
- Move diagnostics check from general prompt into explain prompt
- Split explain prompt into multiple lines for better readability
- Update documentation and config to reflect these changes

This creates a more focused approach where diagnostics are examined as part
of code explanation rather than being a separate concern.

When in insert mode and completion menu is visible, use the original key
mapping instead of triggering the custom function. This prevents
interference with completion menu navigation.

Additionally, improve cursor positioning after inserting completion text by
moving it to the end of inserted value.

Moves uuid, machine_id and quick_hash functions from copilot.lua to utils.lua
module. Also improves type annotations and documentation for the moved
functions. Removes unused table_equals function and renames
blend_color_with_neovim_bg to blend_color for better clarity.

Subject: [PATCH 0703/1571] fix: improve chat buffer rendering and state
 handling

- Make chat buffer non-modifiable by default and only allow modifications
  during content updates and after response is finished
- Join response progress undos together so user can undo whole ask/response at once
- Rerender headers in chat window on text change automatically, which means
  that when users accidentally edits the separators in buffer the highlights do not
  break until next question is asked

Subject: [PATCH 0706/1571] refactor: improve chat output parsing and selection
 handling

Reimplements chat section parsing to better handle code blocks, headers and
sections by storing them in a structured way within the Chat class. This
enables more reliable navigation between sections, code blocks and diffs.

Key changes:
- Add sections and blocks tracking in Chat class
- Improve code block and header parsing reliability
- Consolidate duplicate header parsing code
- Add get_closest_section and get_closest_block helper methods
- Refactor diff handling to use new block parsing
- Clean up quickfix list generation using new block data structure

Subject: [PATCH 0707/1571] feat: add register context and improve selection
 handling

Adds new register context that allows accessing vim register contents in chat
and improves selection handling by:

- Making selection fields required instead of optional
- Improving unnamed register selection to include buffer context
- Deprecating clipboard selection in favor of register context
- Adding proper mark setting for better selection tracking
- Supporting array of default contexts in config

The register context supports all standard vim registers and provides a UI
for selecting them when used. This makes accessing clipboard and other
registers more intuitive.

Subject: [PATCH 0710/1571] fix: improve selection validation checks

Enhance selection validation by properly checking for existence of
start_line and end_line values. This prevents potential nil access errors
when handling invalid selections.

Previously the code only checked if end_line was greater than 0, which
could lead to errors if start_line or end_line were nil.

Subject: [PATCH 0711/1571] feat: add show context command for Copilot Chat

Add new command to show context of the current chat message that maps to `gc` by
default. Unify existing overlay windows into single overlay implementation and
improve resolution of prompts and embeddings by extracting them into separate
functions. The overlay now also shows truncated preview of longer files.

This change improves debugging experience when working with contextual prompts
by allowing users to inspect what files and contexts are being used for the
current prompt.

Subject: [PATCH 0713/1571] fix: use cwd when getting git diffs and files

The current implementation incorrectly used buffer-based paths for git diffs
and file listing. This change properly uses the current working directory
(cwd) for both operations, ensuring correct paths are used when accessing
files and git diffs across the workspace.

The cwd field is now added to the source configuration and properly passed
through to relevant functions. This fixes issues with file listing and git
diff operations when working with files outside the current buffer's
directory.

Closes #577

Subject: [PATCH 0715/1571] feat: add buffer validation for chat window

Add validate() method to Chat class that ensures the window buffer stays in
sync. This prevents potential issues where the window could show incorrect
buffer content by validating and resetting the buffer if needed.

Subject: [PATCH 0717/1571] fix: set default completeopt values for chat buffer

Automatically add 'popup' and 'noinsert' to completeopt if they are not
present when creating chat buffer. This ensures consistent completion
behavior across different Neovim configurations.

Subject: [PATCH 0718/1571] refactor: improve embedding handling with ordered
 map

Replaces ad-hoc embedding handling with a new OrderedMap data structure to
maintain insertion order and prevent duplicates. This change improves code
organization and performance by:

- Adding new OrderedMap utility class for ordered key-value storage
- Refactoring embedding collection to use OrderedMap
- Optimizing file token budget allocation to process from back to front
- Adding threshold for multi-file embeddings processing
- Preserving command prefixes in prompt processing

The changes make the code more maintainable and efficient when handling
multiple file contexts in chat interactions.

Subject: [PATCH 0719/1571] fix: guard completeopt setting behind nvim-0.11.0
 check

The completeopt buffer option was being set unconditionally, which could
cause errors in older Neovim versions. This change adds a version check to
ensure the setting is only modified on Neovim 0.11.0 and newer versions.

Clear chat prompt logic has been moved to dedicated method in Chat class to
improve code reusability and maintainability. Window local cwd detection
has been simplified and now uses VimEnter/WinEnter events instead of
DirChanged for more reliable current working directory tracking.

Subject: [PATCH 0725/1571] refactor: simplify cwd detection

Turns out nvim_win_get_var was a drama queen, throwing exceptions
whenever it couldn't find its precious variable - like a toddler having
a meltdown when they can't find their favorite toy.

Switched to vim.w, the more chill cousin who just returns nil and goes
about their day when something's missing. Now our code won't have an
existential crisis just because cchat_cwd wasn't set for one window.

No more exception-al behavior, just peaceful, quiet coding.

Subject: [PATCH 0729/1571] feat: improve help display and token count
 visibility

The help display and token count mechanism has been improved by:
- Moving token count display to be part of the help message
- Adding clear help functionality to overlay
- Cleaning up finish function parameters and logic
- Using dedicated namespace for spinner
- Simplifying help display logic in chat rendering

This change makes the UI cleaner and more consistent by integrating the
token count into the help display system instead of showing it separately.

Subject: [PATCH 0732/1571] refactor(types): improve type safety and
 organization

- Add proper type annotations and documentation for all classes and methods
- Reorganize UI components into separate ui/ directory
- Remove redundant type comments in favor of proper annotations
- Improve class hierarchy and inheritance relationships
- Clean up function signatures and return types
- Fix overlay component argument order consistency

Subject: [PATCH 0734/1571] fix(selection): properly pass chat config to
 functions

Pass chat configuration to functions that were previously using global state
config, making the code more reliable and avoiding potential race conditions
when multiple chat instances are running simultaneously.

Subject: [PATCH 0735/1571] refactor: improve prompt resolution handling and
 cleanup types

Rewrite prompt resolution to use recursive approach with depth limiting to
prevent infinite loops. Move shared config types to separate class and
improve type definitions. Clean up prompt handling by removing kind field
and simplifying system/user prompt distinction. Fix order of returned
values in resolve_prompts to match usage.

Also includes some code formatting fixes and reordering of config options
for better readability.

Subject: [PATCH 0737/1571] feat: sort completion items by kind and word

Sort completion items consistently by first comparing their kinds, and when
kinds are equal, sort them alphabetically by word. This provides a more
predictable and user-friendly order in completion menus.

Subject: [PATCH 0738/1571] refactor(config): split config into static and
 shared parts properly

Split the plugin configuration into two parts:
- Static config that can only be set via setup()
- Shared config that can be passed as runtime parameters to functions

This improves the configuration management by clearly separating
configuration parameters that should be set only once during setup from
those that can be modified during runtime. Also renamed no_chat option to
headless for better clarity.

Subject: [PATCH 0743/1571] refactor: move embed truncation logic to proper
 places

This commit reorganizes the code to handle truncation of large files and
embeddings in a more consistent way. The changes include:

- Moving ordered_map implementation to top of utils.lua
- Centralizing truncation logic for embeddings with BIG_EMBED_THRESHOLD
- Simplifying outline truncation by moving it to embedding generation
- Updating class type definitions to be more consistent
- Removing duplicate code related to truncation handlers

The main goal is to make the codebase more maintainable by having
truncation logic in appropriate locations rather than scattered across
different files.

Subject: [PATCH 0744/1571] feat: symbol-based filtering for context matches

Add symbol-based filtering system for workspace context to improve match
relevancy. This adds a new ranking system that scores matches based on:
- Exact filename matches (highest priority)
- Symbol name matches (high priority)
- Symbol signature matches (medium priority)

The system uses a scoring mechanism that prioritizes exact matches and
implements TOP_SYMBOLS (64) and TOP_RELATED (20) thresholds to limit
results. This improves context matching accuracy by considering code
structure rather than just content similarity.

Also adds symbol information to debug output for easier troubleshooting.

Subject: [PATCH 0746/1571] fix: improve prompt embedding and ranking

The changes improve how prompts are embedded and ranked in the context
system:
- Move prompt embedding to after initial data ranking to maintain correct
  ordering
- Fix log output to show correct embedded query content
- Trim whitespace from resolved prompts to improve matching

This ensures more accurate context retrieval and better prompt handling in
the chat system.

Subject: [PATCH 0748/1571] refactor: simplify context filtering and ranking

Simplify context filtering and ranking by removing redundant data structures
and utilizing more of vim's built-in table functions. This change:

- Removes OrderedMap usage in favor of direct table operations
- Combines mapping and scoring operations
- Preserves original content in outline objects
- Uses vim.tbl_map and vim.tbl_extend for cleaner data transformations
- Improves code readability and reduces complexity

The functionality remains the same while making the code more maintainable.

Subject: [PATCH 0749/1571] fix: improve sticky prompt handling and section
 detection

This commit improves handling of sticky prompts by:
1. Using proper line splitting and startswith check instead of gmatch
2. Fixing the sticky prefix removal to only match start of line
3. Ensuring proper rendering before section/block detection

The changes make sticky prompts more reliable and fix edge cases in the
UI rendering.

Closes #614

Subject: [PATCH 0750/1571] refactor: migrate to uv async for file operations

Replace plenary async operations with vim.uv async APIs where possible to
improve performance and reduce dependencies. This includes:
- File operations now use vim.uv.fs_* functions
- Simplified files context provider to remove pattern matching
- Moved curl helpers to utils module
- Cleaned up tiktoken loading process

The file operations are still partly synchronous and marked with FIXME
comments for future async migration.

Subject: [PATCH 0752/1571] refactor: optimize vim scheduler usage in chat
 module

Remove redundant vim.schedule calls and replace them with more efficient
async scheduler utilities. This includes:
- Using async.util.scheduler() instead of vim.schedule wrapper functions
- Consolidating scheduler calls to reduce overhead
- Utilizing vim.schedule_wrap for progress callbacks

The changes make the code more maintainable and potentially improve
performance by reducing unnecessary scheduler invocations.

Subject: [PATCH 0753/1571] refactor(mappings): improve key mapping API and
 descriptions

Replace direct mapping key access with named mapping lookups to improve code
organization. Add descriptive labels to keymaps using the plugin name and
mapping name. This change makes the key mapping system more maintainable
and provides better documentation in the key binding help.

Subject: [PATCH 0754/1571] perf: optimize curl connection settings

Improve performance of HTTP requests by:
- Enabling keepalive connections with 60s timeout
- Disabling compression since responses are already streamed
- Maintaining TCP nodelay and no-buffer settings for efficient streaming
- Adding explicit timeouts for better connection handling

The changes aim to reduce latency and improve overall request efficiency
while maintaining reliable streaming behavior.

Subject: [PATCH 0757/1571] fix: parse stream response body again if stream
 returned no response

Sometimes for some reason the stream_func isnt called properly, in that case
the stream content might be in body so try to parse final response body again.

See #619

Subject: [PATCH 0758/1571] fix: make file operations and contexts async

The changes make various file operations and context resolution properly
async by:
- Converting synchronous UV calls to async versions
- Moving context resolution inside async block
- Making tiktoken data loading fully async
- Converting directory scanning to async version
- Adding proper error handling for async UV operations

This improves overall responsiveness of the plugin by preventing blocking
operations from freezing the editor.

Subject: [PATCH 0760/1571] refactor(context): replace io.popen with vim.system

Replace synchronous io.popen git diff call with asynchronous vim.system in
context.lua. Add async scheduler to token fetching and introduce a new utils
helper for system calls.

This change improves overall plugin performance by making git operations
asynchronous and following Neovim's best practices for system calls.

Subject: [PATCH 0762/1571] feat(context): add full file content support for
 files

The files context provider now supports two modes:
- 'list' (default) - includes only filenames in the workspace
- 'full' - includes both filenames and their content

This change provides more flexibility when needing full context from workspace
files. The implementation also adds proper filetype detection and filtering
for files to ensure only text files are included.

Closes #360

This commit improves the stability and efficiency of the embedding system:
- Add token count validation before processing embeddings
- Implement smarter batching based on token limits (8191 max)
- Reduce line threshold for big embeds from 600 to 500
- Improve error handling and logging for embedding failures
- Optimize tiktoken loading and caching

Subject: [PATCH 0765/1571] refactor(copilot): improve embedding reliability

Implement adaptive batch sizing and content thresholding for embeddings to
handle API failures more gracefully. This change:

- Removes manual token counting in favor of API-driven feedback
- Adds progressive batch size reduction when requests fail
- Implements content threshold reduction for large files
- Adds proper curl failure handling with --fail-with-body
- Increases multi-file threshold from 3 to 5 files
- Adjusts embedding thresholds for better performance

Subject: [PATCH 0767/1571] fix: improve debug info window handling

Previously, the debug info window could be opened multiple times and didn't
properly handle async operations. This commit:

- Makes buffer parameter optional in context.buffer()
- Adds proper window cleanup on close
- Wraps debug info building in async operation to prevent UI blocking
- Stores window number reference to manage single instance

Subject: [PATCH 0768/1571] refactor(context): optimize file loading with
 caching

Refactor context.lua to introduce file caching mechanism and improve code
organization around file handling. The main changes include:

- Add file caching to avoid reprocessing unchanged files
- Move outline generation logic into separate build_outline function
- Consolidate embed type definitions into context.lua
- Remove duplicate type definitions from copilot.lua
- Optimize file loading with new get_file helper function

Subject: [PATCH 0770/1571] refactor: simplify buffer handling using builtin
 functions

Replace manual buffer search and creation logic with built-in Neovim functions
bufadd() and bufload(). This change makes the code more concise and reliable
by leveraging Neovim's native buffer management APIs.

The new implementation:
- Removes redundant buffer search loop
- Uses bufadd() to add new buffer
- Uses bufload() to ensure buffer is loaded

Subject: [PATCH 0771/1571] fix: improve logging output format and consistency

Replace vim.inspect usage with new make_string utility function to provide
more consistent and cleaner logging output across the codebase. This makes
logs more readable and uniform when handling both simple values and complex
data structures.

The changes include:
- Add make_string utility function for standardized string conversion
- Replace vim.inspect calls with direct logging or make_string
- Improve error message formatting for better readability

Previously errors in the async chat operation were not properly caught and
handled, which could lead to silent failures. This change adds proper error
handling using pcall and displays errors to users when not in headless mode.

Subject: [PATCH 0774/1571] refactor: unify info display into show_info and
 show_context

Consolidates multiple info display commands (show_system_prompt,
show_user_selection, show_user_context) into two more comprehensive
commands:
- show_info (gi): displays model, agent and system prompt
- show_context (gc): shows selection and embeddings

This change improves UX by providing more organized and complete
information when inspecting chat context and configuration.

BREAKING CHANGE: Removed show_system_prompt (gp), show_user_selection (gs)
and show_user_context mappings in favor of new unified commands.

Subject: [PATCH 0786/1571] refactor: switch to character-based truncation

Previously, the content truncation was based on line count which could lead to
inconsistent token usage when lines had varying lengths. This change switches
to character-based truncation to provide more predictable token consumption.

Key changes:
- Introduced LINE_CHARACTERS constant (100 chars per line)
- Updated BIG_FILE_THRESHOLD and BIG_EMBED_THRESHOLD to use char count
- Refactored generate_line_numbers into generate_content_block that handles
  both line numbering and truncation
- Made truncation logic count total characters instead of lines

Subject: [PATCH 0787/1571] feat: add status notifications for background tasks

Add a new notification system to provide user feedback for background
operations like file scanning, model fetching, and API calls. This improves
the user experience by making it clear when the plugin is performing work.

The changes include:
- New notify module for pub/sub event system
- Integration with spinner UI to show status messages
- Status notifications for file operations, API calls, and embeddings
- Removed redundant logging in favor of user-visible notifications

Subject: [PATCH 0788/1571] feat: make lynx optional for URL context

Previously, lynx was required for the URL context to work. This change makes
lynx optional by adding a fallback to curl when lynx is not available or
fails. The fallback implementation includes HTML content cleanup to provide
readable text.

When lynx is available, it will be used for better text formatting, but the
URL context will still work without it using the curl fallback.

Subject: [PATCH 0800/1571] refactor(prompt): improve config handling in
 resolve_prompts

Change resolve_prompts to handle entire config object instead of just
system_prompt. This allows prompts to modify any config values, not just the
system prompt, making the prompt resolution system more flexible.

The change maintains backwards compatibility while enabling more advanced
prompt configurations.

 - `o1-mini` - This is the faster version of the o1-preview model, balancing the use of complex reasoning with the need for faster responses. It is best suited for code generation and small context operations. You can make 50 requests to this model per day. o1-mini is hosted on Azure.

Subject: [PATCH 0823/1571] refactor: optimize file list processing order

Move file list chunking before content processing to ensure consistent
ordering of operations and improve code flow. Also increase TOP_RELATED
constant from 20 to 25 for better related files detection.

The chunking logic now runs first, followed by optional content processing,
which makes the code more maintainable and logical in its execution order.

Subject: [PATCH 0826/1571] fix: correct chat config handling

When opening chat and asking questions, ensure proper config inheritance
by deep extending chat state config with provided config and global config.
Also move config handling before early returns to maintain consistency.

Closes #676

Subject: [PATCH 0848/1571] feat: Add theme options to select Telescope themes
 (#710)

* feat: Add theme options to select Telescope themes

Added theme options to the M.pick function to allow selection of
dropdown, ivy, and cursor themes.

* refactor: remove theme argument and integrate into opts

Simplified code by removing the theme argument and integrating it into opts.

* fix: correct default theme settings

Fixed to apply the default theme when opts and opts.theme are not set.

Subject: [PATCH 0857/1571] feat: add quickfix list context support

This commit adds support for the quickfix list context in CopilotChat. The
quickfix context allows including the contents of files listed in the
quickfix list as part of the chat context.

The implementation includes:
- New quickfix context type in config.lua
- Function to extract and process quickfix list files
- Updated documentation in README.md with the new context type

Subject: [PATCH 0859/1571] feat: add quickfix list support for chat answers

Split existing quickfix mapping (gq) into two separate mappings:
- gqa: adds all chat answers to quickfix list
- gqd: adds all code diffs to quickfix list (previous gq functionality)

This allows for easier navigation between different parts of the chat
history, particularly when reviewing AI responses.

-line=8: Expression is overly complex. Break down the expression into simpler components.
-line=10: Using camel case here is unconventional for lua. Use snake case instead.

-2. *DO NOT* include any explanations, comments, or line numbers in your response.
-
-3. Ensure the returned code is complete and can be directly used as a replacement for the original code.

+1. Split your response into minimal, focused code changes to produce the shortest possible diffs.
 
-6. Maintain the *SAME INDENTATION* in the returned code as in the source code
+2. IMPORTANT: Every code block MUST have a header with this exact format:
+   [file:<file_name>](<file_path>) line:<start_line>-<end_line>
+   The line numbers are REQUIRED - never omit them.
 
-7. *ONLY* return the new code snippets to be updated, *DO NOT* return the entire file content.
+3. Return ONLY the modified code blocks - no explanations or comments.
 
-8. If the response do not fits in a single message, split the response into multiple messages.
+4. Each code block should contain:
+   - Only the specific lines that need to change
+   - Exact indentation matching the source
+   - Complete code that can directly replace the original
 
-9. Directly above every returned code snippet, add `[file:<file_name>](<file_path>) line:<start_line>-<end_line>`. Example: `[file:copilot.lua](nvim/.config/nvim/lua/config/copilot.lua) line:1-98`. This is markdown link syntax, so make sure to follow it.
+5. When fixing code, check and address any diagnostics issues.
 
-10. When fixing code pay close attention to diagnostics as well. When fixing diagnostics, include diagnostic content in your response.
+6. If multiple separate changes are needed, split them into individual blocks with appropriate headers.
 
-Remember that Your response SHOULD CONTAIN ONLY THE MODIFIED CODE to be used as DIRECT REPLACEMENT to the original file.
+Remember: Your response should ONLY contain file headers with line numbers and code blocks for direct replacement.

 quickfix file entries

We use files not booleans.

This pull request includes a small change to the lua/CopilotChat/context.lua file. The change modifies the quickfix function to use vim.tbl_keys instead of vim.tbl_values when processing unique_files.

Subject: [PATCH 0866/1571] feat(diff): add option to show full diff with diff
 mode

Add new `full_diff` option to show_diff mapping which allows showing a full
diff view instead of unified diff view. When enabled, it will show the
modified file content side by side with original file using Vim's built-in
diff mode.

The full diff mode provides better visualization of changes and allows using
Vim's diff navigation commands to review changes.

Closes #705

Subject: [PATCH 0872/1571] feat(context): add support for commit-specific git
 diffs

Allow viewing diffs for specific commits by passing commit hash/reference to
the git context. This extends the existing git context functionality which
previously only supported staged and unstaged changes.

The change includes:
- Updated documentation in README.md to reflect new git context options
- Modified context handler to support commit references
- Updated config description to mention commit number support

Subject: [PATCH 0879/1571] feat: Report early stop reason to the UI

The Copilot API returns a `finish_reason` field that indicates why the
response stopped. This commit adds this information to the UI, so the
user knows why the response stopped.

If the reason is `stop`, it means that the response was finished normally,
so we don't need to show any message.

Subject: [PATCH 0880/1571] feat: add support for Github Marketplace models

Adds integration with Github Marketplace models available through Azure ML API.
The models are fetched from the Azure catalog and exposed through the same
interface as regular Copilot models. This provides users with access to
additional experimental models while maintaining consistent UX.

The docs are updated to point to official Copilot model documentation and
marketplace models page rather than listing models inline.

 You can list available models with `:CopilotChatModels` command. Model
 determines the AI model used for the chat. You can set the model in the prompt
 by using `$` followed by the model name or default model via config using
-`model` key. Default models are:
-
-- `gpt-4o` - This is the default Copilot Chat model. It is a versatile, multimodal model that excels in both text and image processing and is designed to provide fast, reliable responses. It also has superior performance in non-English languages.
-- `claude-3.5-sonnet` - This model excels at coding tasks across the entire software development lifecycle, from initial design to bug fixes, maintenance to optimizations. Claude is **not available everywhere** so if you do not see it, try github codespaces or VPN.
-- `gemini-2.0-flash-001` - This model has strong coding, math, and reasoning capabilities that makes it well suited to assist with software development.
-- `o1` - This model is focused on advanced reasoning and solving complex problems, in particular in math and science. It responds more slowly than the GPT 4o model. You can make 10 requests to this model per day.
-- `o3-mini` - This model is the next generation of reasoning models, following from o1 and o1-mini. The o3-mini model outperforms o1 on coding benchmarks with response times that are comparable to o1-mini, providing improved quality at nearly the same latency. It is best suited for code generation and small context operations. You can make 50 requests to this model every 12 hours.

+## Providers
+
+Providers are modules that implement integration with different AI providers. Built-in providers are:
+
+- `copilot` - Default GitHub Copilot provider used for chat and embeddings
+- `github_models` - Provider for GitHub Marketplace models
+
+You can define custom providers by adding them to `providers` config. Provider has following fields:
+
+- `disabled?: boolean` - Optional boolean to disable provider
+- `embeddings?: string` - Optional string pointing to provider to use for embeddings
+- `get_token(): string, number?` - Function that returns authentication token and optional expiry timestamp
+- `get_headers(token: string, sessionid: string, machineid: string): table` - Function that returns headers for API requests
+- `get_url(opts: table): string` - Function that returns API endpoint URL for given operation
+- `prepare_input(inputs: table, opts: table, model: table): table` - Function that prepares request body
+- `get_models?(headers: table): table` - Optional function that returns list of available models
+- `get_agents?(headers: table): table` - Optional function that returns list of available agents
+
+Example custom provider:
+
+```lua
+{
+  providers = {
+    my_provider = {
+      -- Required fields
+      get_token = function()

+PROVIDERS                                              *CopilotChat-providers*
+
+Providers are modules that implement integration with different AI providers.
+Built-in providers are:
+
+- `copilot` - Default GitHub Copilot provider used for chat and embeddings
+- `github_models` - Provider for GitHub Marketplace models
+
+You can define custom providers by adding them to `providers` config. Provider
+has following fields:
+
+- `disabled?: boolean` - Optional boolean to disable provider
+- `embeddings?: string` - Optional string pointing to provider to use for embeddings
+- `get_token(): string, number?` - Function that returns authentication token and optional expiry timestamp
+- `get_headers(token: string, sessionid: string, machineid: string): table` - Function that returns headers for API requests
+- `get_url(opts: table): string` - Function that returns API endpoint URL for given operation
+- `prepare_input(inputs: table, opts: table, model: table): table` - Function that prepares request body
+- `get_models?(headers: table): table` - Optional function that returns list of available models
+- `get_agents?(headers: table): table` - Optional function that returns list of available agents

Subject: [PATCH 0888/1571] feat: migrate from Jekyll to Docsify (#774)

* feat: migrate from Jekyll to Docsify

Replace Jekyll-based documentation with Docsify for simpler and more flexible
documentation setup. This change:
- Removes Jekyll configuration and build step from GH Pages workflow
- Adds basic Docsify setup with search and image zoom plugins
- Creates .nojekyll file to disable GitHub Pages Jekyll processing

The migration provides a more maintainable documentation system that works
better with single-page documentation sites.

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

Change all H3 (###) section headers to H2 (##) for better document
structure and consistency. This improves the readability and navigation
of the README.md file by maintaining a proper heading hierarchy.

Remove roadmap section as it was outdated and contained only two
generic items.

Subject: [PATCH 0896/1571] feat: switch documentation to dark theme

Changes the docsify theme from vue to simple-dark theme and adds error
logging for failed embedding requests. This improves readability for users
who prefer dark mode and helps with debugging embedding issues.

- Replace vue.css with theme-simple-dark.css
- Add docsify-themeable script
- Add debug logging for embedding errors

Subject: [PATCH 0897/1571] refactor: simplify HTTP headers

Remove unnecessary HTTP headers and standardize header casing across the
codebase. This simplifies the header management by:

- Removing unused machine ID and session ID tracking
- Using consistent header casing (capitalized)
- Removing redundant version headers
- Simplifying authorization header format

These changes make the code more maintainable while preserving core
functionality.

Subject: [PATCH 0900/1571] fix: improve provider handling and model uniqueness

Makes the provider handling more robust by:
- Making get_token optional for providers
- Adding error handling for model and agent fetching
- Ensuring unique model/agent IDs by appending provider name on conflicts
- Sorting providers for consistent order
- Removing provider suffix from model name before request

These changes improve reliability when multiple providers are configured
and prevent conflicts between models/agents with the same IDs from
different providers.

Restructures the codebase by moving mapping-related callback functions from
init.lua to config/mappings.lua. This improves code organization and makes
mapping configuration more self-contained.

- Adds callback field to mapping config class
- Moves all mapping callback functions to their respective mapping configs
- Extracts shared functions to utils module
- Simplifies mapping registration by using callback field

+### Models
 
-You can list available models with `:CopilotChatModels` command. Model determines the AI model used for the chat.  
-You can set the model in the prompt by using `$` followed by the model name or default model via config using `model` key.  
-For list of models supported by Copilot Chat see [here](https://docs.github.com/en/copilot/using-github-copilot/ai-models/changing-the-ai-model-for-copilot-chat#ai-models-for-copilot-chat).  
-This plugin also supports Github Marketplace Models. These have fairly low limits but are useful for experimentation. For more information see [here](https://github.com/marketplace/models).
+You can control which AI model to use in three ways:
 
-## Agents
+1. List available models with `:CopilotChatModels`
+2. Set model in prompt with `$model_name`
+3. Configure default model via `model` config key
 
-Agents are used to determine the AI agent used for the chat. You can list available agents with `:CopilotChatAgents` command.  
-You can set the agent in the prompt by using `@` followed by the agent name or default agent via config using `agent` key.  
-Default "noop" agent is `copilot`.

 ## Contexts
 
-Contexts are used to determine the context of the chat.  
-You can add context to the prompt by using `#` followed by the context name or default context via config using `context` (can be single or array) key.  
-Any amount of context can be added to the prompt.  
-If context supports input, you can set the input in the prompt by using `:` followed by the input (or pressing `complete` key after `:`).  
-Default contexts are:
-
-- `buffer` - Includes specified buffer in chat context. Supports input (default current).
-  - `buffer:<number>` - Includes buffer with specified number in chat context.
-- `buffers` - Includes all buffers in chat context. Supports input (default listed).
-  - `buffers:listed` - Includes only listed buffers in chat context.
-  - `buffers:all` - Includes all buffers in chat context.
-- `file` - Includes content of provided file in chat context. Supports input.
-  - `file:<path>` - Includes content of specified file in chat context.
-- `files` - Includes all non-hidden files in the current workspace in chat context. Supports input (default list).
-  - `files:list` - Only lists file names.
-  - `files:full` - Includes file content for each file found. Can be slow on large workspaces, use with care.
-- `git` - Requires `git`. Includes current git diff in chat context. Supports input (default unstaged, also accepts commit number).
-  - `git:unstaged` - Includes unstaged changes in chat context.
-  - `git:staged` - Includes staged changes in chat context.
-  - `git:<commit>` - Includes changes from specified commit in chat context.
-- `url` - Includes content of provided URL in chat context. Supports input.
-  - `url:<url>` - Includes content of specified URL in chat context.
-- `register` - Includes contents of register in chat context. Supports input (default +, e.g clipboard).
-  - `register:<register>` - Includes contents of specified register in chat context.
-- `quickfix` - Includes quickfix list file contents in chat context.

-Contexts are used to determine the context of the chat. You can add context to
-the prompt by using `#` followed by the context name or default context via
-config using `context` (can be single or array) key. Any amount of context can
-be added to the prompt. If context supports input, you can set the input in the
-prompt by using `:` followed by the input (or pressing `complete` key after
-`:`). Default contexts are:
-
-- `buffer` - Includes specified buffer in chat context. Supports input (default current).
-    - `buffer:<number>` - Includes buffer with specified number in chat context.
-- `buffers` - Includes all buffers in chat context. Supports input (default listed).
-    - `buffers:listed` - Includes only listed buffers in chat context.
-    - `buffers:all` - Includes all buffers in chat context.
-- `file` - Includes content of provided file in chat context. Supports input.
-    - `file:<path>` - Includes content of specified file in chat context.
-- `files` - Includes all non-hidden files in the current workspace in chat context. Supports input (default list).
-    - `files:list` - Only lists file names.
-    - `files:full` - Includes file content for each file found. Can be slow on large workspaces, use with care.
-- `git` - Requires `git`. Includes current git diff in chat context. Supports input (default unstaged, also accepts commit number).
-    - `git:unstaged` - Includes unstaged changes in chat context.
-    - `git:staged` - Includes staged changes in chat context.
-    - `git:<commit>` - Includes changes from specified commit in chat context.
-- `url` - Includes content of provided URL in chat context. Supports input.

-Inline chat ~
+==============================================================================
+6. Tips and Examples                           *CopilotChat-tips-and-examples*
 
-Change the window layout to `float` and position relative to cursor to make the
-window look like inline chat. This will allow you to chat with Copilot without
-opening a new window.
+
+QUICK CHAT WITH BUFFER                    *CopilotChat-quick-chat-with-buffer*
+
+Set up a quick chat command that uses the entire buffer content:

-          row = 1
-        }
-      }
+    -- Quick chat keybinding
+    vim.keymap.set('n', '<leader>ccq', function()
+      local input = vim.fn.input("Quick Chat: ")

Subject: [PATCH 0907/1571] fix(ollama): use correct module import path

The change fixes the ollama provider by using the proper module import path
'CopilotChat.utils' instead of directly accessing the local cutils module.
This ensures consistent module resolution across the codebase.

Subject: [PATCH 0913/1571] fix(embeddings): improve embedding resolution
 reliability (#794)

* fix(embeddings): improve embedding resolution reliability

Previously the code would error when embeddings provider was not found.
Now it gracefully handles missing providers by skipping embeddings
calculation. This improves reliability when custom providers don't
implement embeddings support.

Also adds null check for spatial distance calculation and moves provider
interface documentation before the example in README.md for better
readability.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

Subject: [PATCH 0915/1571] refactor: streamline debug info into `info` mapping

Move debug info functionality into info mapping and remove separate
debug UI window. This simplifies the codebase while keeping all debugging
functionality available through a unified interface. The debug info now
includes:

- Log file location
- History file location
- Temp files directory
- Model and agent info
- System prompt details

BREAKING CHANGE: Removes CopilotChatDebugInfo command. Use `gi` in chat
instead.

Subject: [PATCH 0919/1571] refactor: Make history fully respect buffer
 contents

Move chat history handling from the client to the chat UI component to better
separate concerns and improve code organization. History is now maintained and
parsed directly in the chat UI rather than being stored in the client.

Key changes:
- Remove history field and related methods from client
- Add parse_history and load_history methods to chat UI
- Update save/load functions to work with chat UI history
- Cache section/block content during rendering for better performance
- Modifying buffer contents now allows also modifying history

Update yank functionality to use closest chat block instead of diff content.
Add proper type annotations for contexts and prompts tables. Clean up
unnecessary comment and improve type definition for callback function.

This change makes the yank feature more intuitive by copying the actual

Subject: [PATCH 0923/1571] perf: improve file scanning and async input
 handling

The changes optimize file scanning by using a dedicated scan_dir utility with
gitignore support and improve async handling in context input processing:

- Replace vim.fn.glob with optimized scan_dir utility
- Add gitignore respect to file scanning
- Fix potential UI freezes by properly handling async context input
- Ensure scheduler is called before UI operations

Closes #690

Subject: [PATCH 0926/1571] refactor: make client module stateless

The client module has been refactored to be stateless by making it a singleton
and moving provider initialization to a separate method. This simplifies the
overall architecture and makes the code more maintainable.

Additional changes:
- Improved reference handling and generation
- Updated header naming convention for Copilot requests
- Fixed embedding context resolution to pass proper params
- Removed redundant client state from main module

Subject: [PATCH 0930/1571] perf: improve file and context matching performance

Introduces similarity thresholds and file limits to improve matching
performance:
- Add MIN_SYMBOL_SIMILARITY (0.4) and MIN_SEMANTIC_SIMILARITY (0.3)
  thresholds
- Implement max_files limit (1000) for directory scanning
- Refactor ranking algorithms to filter by similarity instead of taking
  top N
- Improve symbol matching to use normalized similarity scores

These changes help prevent performance issues with large codebases while
maintaining matching quality by using similarity-based filtering.

Subject: [PATCH 0931/1571] refactor(search): improve symbol search and
 references

Improves symbol search algorithm by using trigram-based similarity matching
instead of simple term matching. This provides better accuracy for fuzzy
matches and handles compound words better.

Key changes:
- Replace basic term matching with trigram-based Jaccard similarity
- Normalize and weight symbol matches separately from filename matches
- Add reference list display in chat UI
- Move authentication status messages to more logical locations
- Fix various edge cases and improve code organization

Previously, headers were hardcoded in the get_models function which made the

The references section in the chat UI has been improved by moving it above
the help section and displaying it with proper highlighting using virtual
lines. This change also fixes a diagnostic warning in the sticky prompt
handling code.

Changes:
- Move references section above help section
- Use virtual lines with highlighting for references display
- Add diagnostic disable comment for param-type-mismatch warning

Subject: [PATCH 0935/1571] fix: make token counting optional in chat client

Currently token counting and limiting messages is enforced for all chat
providers, but this should be optional as not all chat providers support
token limiting. This change makes token counting optional and only enabled
when max_tokens and tokenizer are provided in model config.

The types in providers.lua have also been updated to reflect the optional
nature of these fields.

Subject: [PATCH 0938/1571] fix(context): ensure minimum number of search
 results

Adds MIN_RESULTS constant to guarantee at least 3 results are returned when
searching for related code context, even if they don't meet the similarity
threshold. This improves the quality of contextual responses by preventing
cases where too few results would be returned.

Also adds score normalization for symbol-based search and debug logging for
generated messages.

Subject: [PATCH 0939/1571] refactor(scoring): improve context relevancy
 scoring

Remove MIN_RESULTS constant and use MULTI_FILE_THRESHOLD consistently for
minimum results filtering. Improve scoring by adding base score to symbol
matches and simplify spatial distance calculation. Add score bonus for
current file context to improve relevancy of local results.

These changes make the context selection more accurate by:
- Using consistent thresholds
- Better handling of symbol matching scores
- Prioritizing local context appropriately

The change removes the conditional check that filtered out entries with zero
scores. This ensures all entries are included in the results array, allowing
for proper normalization of scores across the entire dataset.

Subject: [PATCH 0942/1571] refactor!: improve provider resolution

Improve the way how different providers are resolved and configured. Make sure
the output and input processing is more consistent between providers by
providing common interface that providers must implement.

Improvements:
- Change embeddings field to embed for clarity
- Add proper types for provider inputs and outputs
- Make provider resolution more generic
- Make common provider interface clearer
- Add types for model and agent configs
- Make prepare_input and prepare_output more consistent

Subject: [PATCH 0944/1571] fix: correct agent handling in chat client

Improves agent handling in the chat client by:
- Fixing agent config extension when agent is not provided
- Correcting URL generation for agent endpoints
- Fixing agent list mapping to use proper agent IDs
- Improving type annotations for provider options

These changes make the agent-related functionality more robust and
type-safe throughout the codebase.

Subject: [PATCH 0945/1571] refactor!: simplify header authentication

Simplifies provider interface by combining get_token and get_headers into a single
get_headers method that returns both headers and expiration time. This reduces
complexity and removes the need to pass tokens between functions.

Updates documentation to reflect the new provider interface and adds better type
hints for provider methods. Also extracts copilot embeddings provider into a
separate module.

Subject: [PATCH 0948/1571] feat: add utils.empty() function for checking empty
 values

This commit introduces a new utility function `empty()` that checks if a value
is empty. This function handles nil values, empty tables, and whitespace-only
strings.

The function is used to improve empty value checking across the codebase,
replacing direct nil checks with the more robust empty() function.

Changes:
- Add utils.empty() function
- Update client.lua to use empty() for response validation
- Update chat.lua to use empty() for content checks

Subject: [PATCH 0950/1571] refactor(http): simplify curl request handling

Refactor HTTP request handling to improve JSON processing and error handling:
- Add json_request/json_response flags to automatically handle JSON conversion
- Make get_headers optional for providers
- Simplify error handling and status code checks
- Standardize header casing and content-type handling
- Remove redundant JSON encoding/decoding operations

The changes make the code more maintainable and reduce duplication while
keeping the same functionality.

Subject: [PATCH 0952/1571] docs: move examples and providers to wiki

To keep the main README.md clean and maintainable, move the examples,
tips, and external providers sections to dedicated wiki pages. This
improves documentation organization while keeping the same information
accessible.

The following sections were moved:
- Ollama provider example -> External Providers wiki page
- Tips and Examples -> Examples and Tips wiki page

 # Configuration
 
@@ -682,84 +643,9 @@ chat.setup({
 })
 ```
 
-# Tips and Examples
-
-## Quick Chat with Buffer
-
-Set up a quick chat command that uses the entire buffer content:
-
-```lua
--- Quick chat keybinding
-vim.keymap.set('n', '<leader>ccq', function()
-  local input = vim.fn.input("Quick Chat: ")
-  if input ~= "" then
-    require("CopilotChat").ask(input, {
-      selection = require("CopilotChat.select").buffer
-    })
-  end
-end, { desc = "CopilotChat - Quick chat" })
-```
-
-## Inline Chat Window
-
-Configure the chat window to appear inline near the cursor:
-
-```lua
-require("CopilotChat").setup({
-  window = {
-    layout = 'float',
-    relative = 'cursor',
-    width = 1,
-    height = 0.4,
-    row = 1
-  }
-})
-```
-
-## Telescope Integration
-
-Requires [telescope.nvim](https://github.com/nvim-telescope/telescope.nvim):
-
-```lua
-vim.keymap.set('n', '<leader>ccp', function()
-  local actions = require("CopilotChat.actions")
-  require("CopilotChat.integrations.telescope").pick(actions.prompt_actions())
-end, { desc = "CopilotChat - Prompt actions" })
-```
-
-## Quick Search with Perplexity
-
-Requires [PerplexityAI Agent](https://github.com/marketplace/perplexityai):
-
-```lua
-vim.keymap.set({ 'n', 'v' }, '<leader>ccs', function()
-  local input = vim.fn.input("Perplexity: ")
-  if input ~= "" then
-    require("CopilotChat").ask(input, {
-      agent = "perplexityai",
-      selection = false,
-    })
-  end
-end, { desc = "CopilotChat - Perplexity Search" })
-```
-
-## Markdown Rendering
-
-Use [render-markdown.nvim](https://github.com/MeanderingProgrammer/render-markdown.nvim) for better chat display:
+# Examples
 
-```lua
--- Register copilot-chat filetype
-require('render-markdown').setup({
-  file_types = { 'markdown', 'copilot-chat' },
-})
-
--- Adjust chat display settings
-require('CopilotChat').setup({
-  highlight_headers = false,
-  separator = '---',
-  error_header = '> [!ERROR] Error',
-})
-```
+For examples, see the [examples wiki page](https://github.com/CopilotC-Nvim/CopilotChat.nvim/wiki/Examples-and-Tips).

Subject: [PATCH 0955/1571] fix: clear chat selection marks and highlights on
 reset

When resetting the chat, properly clean up any
remaining selection marks and highlights from the source buffer. This
prevents leftover visual indicators from persisting after the chat session
ends.

Subject: [PATCH 0956/1571] feat: add keyword highlights and improve buffer
 docs

This commit adds syntax highlighting for keywords in the chat buffer and
improves documentation around buffer types and highlights. It also:

- Removes the development version check in health.lua in favor of stable
  version check only
- Removes is_stable() utility function as it's no longer needed
- Updates CopilotChatSpinner highlight to use DiagnosticHint
- Improves README documentation for buffer types and highlight groups

The highlight keywords are populated from completion items and are updated
when entering the chat buffer.

Subject: [PATCH 0959/1571] refactor: migrate chat history from UI to client
 layer

The chat history was previously managed in the UI layer through parsing of
rendered chat sections. This change moves the history management directly
into the client layer for better separation of concerns.

Key changes:
- Add history field to Client class to store conversation history
- Remove parse_history from Chat UI class
- Update history handling in ask function to use client's history
- Maintain history only when not in headless mode
- Clean up header pattern matching in chat UI
- Fix diagnostic namespace to use consistent naming

Using chat buffer for client history had issues with resolving the history
properly without stuff like #buffers etc so just go back to this solution.

Enhance error handling and message parsing in the chat client:
- Add null check for job before shutdown
- Improve JSON parsing error handling with dedicated utility function
- Clean up stream event handling
- Simplify error message passing in curl utilities
- Remove redundant string conversions for error messages

The changes make the error handling more robust and consistent across
the codebase while reducing unnecessary string transformations.

Subject: [PATCH 0962/1571] refactor: improve code using vim.iter and tbl_map

Replace multiple manual table operations with vim.iter and vim.tbl_map for
better readability and more idiomatic Lua code. This change simplifies the
data transformations in providers.lua and improves scheduling in
tiktoken.lua.

Subject: [PATCH 0963/1571] feat: include chat history in embedding query

When filtering embeddings, include previous user messages from chat history
in the query string for better context matching. This helps improve the
relevance of filtered embeddings by considering the full conversation
context rather than just the current prompt.

The history inclusion can be disabled via the headless config option.

Subject: [PATCH 0965/1571] feat(prompts): enhance clarity of prompt
 instructions

The changes improve explicit behavior requirements in prompt templates by:
- Adding instruction to handle line-numbered code snippets
- Expanding code review criteria to cover more quality aspects
- Clarifying exact line number requirements for code generation
- Adding more specific formatting and completeness requirements
- Improving explanation focus to cover non-obvious code aspects

The updates make the prompts more precise and help ensure more consistent
and higher quality AI responses across different usage scenarios.

Closes #760

Subject: [PATCH 0969/1571] feat!: add glob pattern support for file context

Replace the basic list/full mode for files context with glob pattern matching
support. This allows for more granular file filtering in the workspace using
standard glob patterns like *.lua or **/*.js.

Split the original files context into two separate contexts:
- files: Returns file contents matching the glob pattern
- filenames: Returns only filenames matching the glob pattern

BREAKING CHANGE: The files context no longer accepts list/full as input
options. Instead, it now expects a glob pattern. The old functionality has
been split into two separate contexts: files and filenames.

Subject: [PATCH 0971/1571] refactor(context): improve file search options
 handling

Refactor the file context handling to use a more flexible search options
approach. Instead of passing individual parameters, introduce a table-based
configuration that can be extended with additional options.

This change makes the API more maintainable and extensible while keeping
backward compatibility through the use of vim.tbl_extend.

Subject: [PATCH 0979/1571] feat: improve chat buffer syntax highlighting

Add dedicated highlight group for input contexts and update existing highlight
groups to better organize visual elements in the chat buffer. CopilotChatSpinner
is now renamed to CopilotChatStatus for better semantics. Syntax matching is
improved to handle input contexts with proper containment rules.

Enhance error reporting by preserving original error message when embedding
requests fail instead of generic error. Clean up error message format by
removing all file:line prefixes for better readability.

Subject: [PATCH 0982/1571] refactor: move embedding cache to context module

Move embedding cache functionality from client to context module to improve
separation of concerns and code organization. The cache is now maintained in
the context module which is more appropriate since it deals with context
management.

This change simplifies the client module by removing the embedding cache
responsibility while maintaining the same caching functionality in a more
logical location.

Using vim.fs.normalize provides better path normalization across
different operating systems. This change improves path handling
consistency in file operations for the CopilotChat plugin.

There's also a typo fix in the function name from 'normalie' to
'normalize' at one location.

Subject: [PATCH 0992/1571] refactor: replace vim.fn functions with vim.fs
 equivalents

Remove dependency on vim.fn.fnamemodify for file operations by using
the more modern vim.fs API instead. This change:
- replaces vim.fn.fnamemodify with vim.fs.normalize for path comparison
- replaces vim.fn.fnamemodify with vim.fs.basename for filename extraction
- removes unnecessary async scheduler call in client.lua

Part of the effort to reduce reliance on Vim functions.

Subject: [PATCH 0995/1571] feat: add CopilotChatPrompts command

Add new command to easily browse and select from available prompt
actions. This replaces the previous manual approach of requiring
users to create actions through the API, providing a more
user-friendly interface similar to the existing models and agents
selection commands.

This is preparation to deprecated CopilotChat.actions and CopilotChat.integrations

Subject: [PATCH 1001/1571] feat(ui): add option to control references display
 mode

Add new configuration option `references_display` that allows
users to control how references are displayed in chat responses.
Two modes are supported:
- 'virtual': displays references as virtual text (default)
- 'write': writes references directly into the chat buffer as

Subject: [PATCH 1003/1571] refactor(models): simplify model listing by using
 model_picker_enabled

Remove version field from models in favor of using just ID for model
identification. Simplify model and agent listing with consistent sorting
by provider and ID. Add model_picker_enabled flag for Copilot models to
filter models that should appear in the model picker.

Subject: [PATCH 1012/1571] refactor: replace plenary scheduler with internal
 implementation

Remove dependency on plenary.async.util.scheduler() by implementing a
custom schedule_main() function that only schedules when necessary.
This allows the plugin to work without requiring plenary's scheduling
mechanism. Also fixes JSON decoding by ensuring response body is
properly converted to string.

Subject: [PATCH 1017/1571] feat: add vim.ui.select health check

Add health check to verify if vim.ui.select is using the default
implementation or has been overridden by a custom implementation.
This helps users identify if they could improve their experience by
using a better picker integration.

Also improved formatting consistency in treesitter warning messages.

Subject: [PATCH 1020/1571] refactor: streamline system prompts architecture
 (#890)

* refactor: streamline system prompts architecture

Integrate code generation instructions directly into base prompt to
simplify the system architecture. Remove the separate COPILOT_GENERATE
prompt and update all references to it throughout the codebase.

The format instructions for code changes have been moved to the base
prompt to ensure consistent formatting across all interaction modes.
This change improves maintainability while preserving full functionality.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

Subject: [PATCH 1023/1571] feat(health): add setup check to health module

Add a required setup verification step that warns users when the plugin
hasn't been properly initialized. This helps troubleshoot common
issues where users forget to call setup().

Also reorganize health checks by removing redundant header and moving the
debug info suggestion to a more appropriate location.

Subject: [PATCH 1024/1571] fix: clear config when resetting chat

When clearing the chat with the clear method, ensure the config
is also reset to an empty table along with references and token
counts. This prevents stale configuration from persisting across
chat resets.

Subject: [PATCH 1025/1571] fix: prevent errors when accessing window config

Previously, the Chat:clear() method was resetting the entire config
object to an empty table, causing potential nil access errors when
trying to access config.window.layout. This change:

1. Removes the config reset in the clear() method to preserve settings
2. Adds a nil check when accessing config.window to prevent errors

Closes #895

Subject: [PATCH 1030/1571] feat(context): add system context for shell command
 output

Adds a new 'system' context that allows including the output of shell
commands in chat context. This feature is useful for incorporating
system information or command results directly into Copilot Chat.

The implementation:
- Updates documentation in README.md
- Adds new context entry in contexts.lua with input prompt
- Implements M.cmd() function with cross-platform support
- Adds status notifications for context operations

Subject: [PATCH 1032/1571] refactor!: centralize sticky prompt and selection
 handling

This refactoring improves the CopilotChat plugin's state management by:
- Adding `insert_sticky` function to centralize sticky prompt management
- Creating `set_selection` to provide a cleaner API for selection handling
- Consolidating highlight management in `update_highlights`
- Standardizing function signatures and return values
- Improving `Chat:set_prompt` functionality
- Removing redundant code for better maintainability

BREAKING CHANGES:
- `M.resolve_prompt` now returns config first and prompt second
- `M.update_selection` removed in favor of new `M.set_selection` function
- `M.resolve_embeddings` renamed to `M.resolve_context`
- Selection setting now only configurable in global config, not per-operation
- `get_selection` no longer accepts a config parameter
- Selection handling moved from dynamic config to static global config
- Changed sticky format and processing approach
- Prompts in config now use explicit `sticky` property instead of prefixing

Subject: [PATCH 1039/1571] refactor(ui): centralize overlay and diff
 functionality

Refactor the Copilot Chat UI architecture by:
- Moving diff functionality into Chat class
- Removing the separate Diff class implementation
- Simplifying callback signatures in mappings
- Making chat instance accessible through the module
- Adding proper type definitions for diffs and overlays
- Improving overlay behavior and restoring cursor position

Subject: [PATCH 1040/1571] refactor(api): improve Chat class organization and
 privacy

This commit restructures the CopilotChat API, particularly the Chat class
in ui/chat.lua. Changes include:
- Move method definitions to match class-like organization
- Add JSDoc comments for public methods
- Mark private/protected methods and properties
- Rename method 'active()' to 'focused()' for clarity
- Move class annotations from file start to declaration
- Rename 'overlay' to 'chat_overlay' to avoid property/method conflict
- Replace 'show_overlay()' method with simpler 'overlay()' name

Subject: [PATCH 1041/1571] feat: add remember_as_sticky config option

Add configuration option to control whether model/agent/context are
remembered as sticky prompts when asking questions. This provides more
control over the persistence behavior.

Also added a 'grx' shortcut to clear all sticky prompts and changed
the toggle sticky keymap from 'gr' to 'grr' to avoid conflicts.

Subject: [PATCH 1049/1571] feat: allow per-chat selection configurations

Make selection behavior configurable per-chat instance rather than
only globally. This enables different selection strategies for different
chat sessions while maintaining backward compatibility with the global
configuration.

The selection field is moved higher in the config file for better
visibility, and documentation is updated to reflect this change.

Subject: [PATCH 1051/1571] fix: properly merge selection configuration

The change replaces the previous selection config resolver with a deep
merge between the global and chat-specific configurations. This ensures
all nested configuration values are properly merged instead of just
using one or the other.

Restructure the API documentation into logical sections for better
readability and include additional API methods that were previously
undocumented. Add new sections for:
- Core chat functions
- Chat window UI methods
- More comprehensive examples

This provides users with a clearer overview of the available
functionality and how to use the plugin effectively.

Subject: [PATCH 1054/1571] feat!: mark async functions with annotations

Mark async functions with proper `---@async` annotations to clearly
indicate which functions require running in an async context. Update
complete_items to return directly instead of using a callback pattern,
improving code clarity and consistency with other async functions.

Functions now properly indicate when they require plenary.async.run in
the API documentation.

BREAKING CHANGE: chat.complete_items() is now async instead of using callback

Subject: [PATCH 1056/1571] fix: eliminate reference duplication with ordered
 map

Use ordered_map instead of an array to prevent duplicate references when
the same file is referenced multiple times. This improves how references
are handled and displayed in the response by:
- Including the current selection as a reference
- Ensuring each file appears only once in references
- Preserving reference order for consistent display

Subject: [PATCH 1062/1571] feat: add conversation memory summarization

Implement a memory system that automatically summarizes chat history
to maintain context across long conversations while managing token
usage. The system:
- Tracks conversation history and generates summaries when needed
- Includes summarized memory in system prompts for context
- Only loads recent messages after the last summarization point
- Optimizes token usage by accounting for memory in calculations

This reduces issues with context length limitations while preserving
important information from previous interactions.

Inspired by:
https://github.com/yetone/avante.nvim/pull/1508

as it was pretty good idea, this PR takes it a bit further

Subject: [PATCH 1064/1571] refactor(prompts): use proper fields for prompt
 settings

Instead of sticky use context/system_prompt and rely on remember_as_sticky
configuration for this to be remembered.

Also add support for resolving system_prompts by name

Subject: [PATCH 1070/1571] fix: correct history storage in client

The commit fixes two issues:
- Updates direct access to history table to use self.history in the
  client module, removing redundant reassignment
- Adds a display for memory content in the chat overlay when available

This improves both correctness and usability of the Copilot Chat plugin.

Subject: [PATCH 1074/1571] refactor(memory): improve conversation memory
 management

The memory summarization mechanism is now integrated directly into token
budget handling instead of being called separately before each chat
request. This improves efficiency by:

1. Only summarizing when we actually exceed the token limit
2. Properly recalculating token budgets after summarization
3. Adding consistent references tracking for embedded files
4. Moving job ID setting to after initial setup work is complete

This change makes memory management more robust and predictable while
maintaining the same functionality.

Subject: [PATCH 1079/1571] fix: manually trigger BufEnter when restoring
 buffers

The nvim_win_set_buf API doesn't automatically trigger BufEnter events
when switching buffers. This was causing issues with proper state
updates in the Copilot Chat UI when navigating between buffers.

This commit adds explicit BufEnter triggering and simplifies some
related code to ensure proper event handling.

When receiving empty responses from Copilot Chat, the code now properly
handles the error case by setting an appropriate error message and
displaying it to the user. This prevents silent failures and improves
the user experience by providing clear feedback.

Also removes redundant condition checking and cleans up code flow for
better readability.

Update the conversation summarization feature with:
- Rename function from `summarize_memory` to `summarize_history`
- Enhance system prompt with better formatting guidelines
- Add directive to preserve code samples and configurations
- Improve prompt clarity for better technical summaries
- Add tracking for unresolved questions/issues

These changes make history summarization more effective by producing
better structured and more comprehensive technical summaries.

Subject: [PATCH 1088/1571] feat: show source information in chat info panel

When displaying chat information, add the source filename to provide
better context about where the chat was initiated from. This enhances
debugging and improves user experience by making it clear which file
is associated with the current chat session.

Subject: [PATCH 1089/1571] fix: improve source buffer selection for headless
 mode

The update_source function now correctly determines the source buffer
when running in headless mode by checking if we're in the chat window
and using the appropriate window (previous window when in chat,
current window otherwise).

This makes the plugin work properly in headless environments where
window navigation behaves differently.

Subject: [PATCH 1090/1571] feat(search)!: use ripgrep when available for file
 scanning (#953)

* feat(search)!: use ripgrep when available for file scanning

Adds ripgrep integration to improve search performance when scanning
directories. Falls back to the existing scandir implementation when
ripgrep is not available. Updates the configuration options to use
more consistent naming and adds health check for the ripgrep
dependency. Also cleans up installation instructions in README.

BREAKING CHANGE: Due to previous incorrect glob handling,
.lua patterns etc need to be specified as *.lua

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* [pre-commit.ci] auto fixes from pre-commit.com hooks

Subject: [PATCH 1093/1571] feat: improve default file scanning arguments

Define and apply sensible default arguments for file scanning operations
across the codebase. This adds a central configuration for max_count,
max_depth and no_ignore parameters, making file operations more consistent.

The changes also improve the handling of max_count=0, which now correctly
disables the file count limit rather than returning an empty result set.

Subject: [PATCH 1094/1571] fix(readme): remove Tab mapping in normal mode for
 chat

The Tab key was incorrectly documented as working in normal mode for
triggering/accepting the completion menu for tokens in the chat interface.
This commit corrects the documentation to show that Tab is only available
in insert mode.

Previously system_prompt could only be set using the full prompt object path.
Now users can simply specify the prompt name as a string, and the system will
resolve it to the actual prompt content automatically.

Subject: [PATCH 1102/1571] feat(chat): add multi-diff support

Enhance chat interface to support filtering sections by type (question
or answer) and improve diff handling. The show_diff function now
applies all diffs from the same file when in full_diff mode,
providing a more complete view of changes.

Subject: [PATCH 1105/1571] fix: disable auto-completion without proper
 completeopt

Prevents completion from triggering automatically in chat buffers when
required completeopt settings ('noinsert' and 'popup') are missing.
This resolves issues where completion would behave unexpectedly.

Also updates the warning message in README.md to clarify this requirement.

Subject: [PATCH 1107/1571] refactor(context): remove redundant toLowerCase
 calls

Remove unnecessary `:lower()` calls when processing query text,
as the trigram functionality already handles case normalization.
Also added missing function documentation with parameter and return
type annotations.

Subject: [PATCH 1112/1571] feat: add context provider command helpers to
 prompt

Add system prompt section that instructs Copilot to request additional
context using available context providers (#command:input format).
Available context providers with descriptions are now included in the
system prompt, making it easier for users to get relevant context for
their queries.

The implementation passes context metadata to the LLM and includes proper
formatting examples, ensuring that Copilot can effectively guide users to
provide the right context when needed.

Subject: [PATCH 1114/1571] feat(context): improve context help and code block
 handling

Enhance the context suggestion UI by:
- Adding clearer examples for context providers with descriptions
- Fixing indentation in the help text for better readability
- Adding logic to detect code blocks to prevent parsing '>' markers
  inside code examples as context requests
- Improving guidance for users when requesting additional context

This change makes the context help more user-friendly and prevents
false positives when parsing context requests.

Subject: [PATCH 1119/1571] fix: guard against auth and API failures

Improve error handling in fetch_models and fetch_agents by adding explicit
authentication failure checks and using goto statements to continue loop
execution when errors occur. This prevents the code from attempting to
process invalid responses.

Subject: [PATCH 1120/1571] refactor(context): simplify context handling with
 direct methods

Reorganize context handling by moving functionality from separate methods
into more streamlined direct implementations. Replace context.buffer(),
context.file(), etc. with exposed get_* methods that can be called
directly.

The changes also improve notification transparency by showing which
context is being resolved and with what input. This refactoring removes
redundant code while maintaining the same functionality, resulting in a
more maintainable codebase.

 providers

Update the context prompt to consistently use backticks around all inputs
for context providers. This makes the syntax more uniform and clarifies
how to properly use context providers with spaces or special characters
in input parameters.

Also clarifies the system context provider description to indicate it
should be used judiciously.

Subject: [PATCH 1125/1571] refactor(context)!: move cwd handling to source
 object

Move window working directory logic from utils.win_cwd() to a method on
the source object. This improves encapsulation by keeping the directory
handling logic closer to the source object itself, while maintaining the
same functionality.

The new approach uses a cwd() function on the source object that returns
the appropriate directory value, simplifying how context providers access
the current working directory.

Subject: [PATCH 1126/1571] feat: expose source buffer API and support
 disabling mappings

Refactor source buffer handling by exposing public API functions to get
and set the source buffer. This allows greater flexibility for plugins or
users who need to interact with the source buffer programmatically.

Also update the mapping type definitions to explicitly support false/nil
values for disabling specific mappings, and add null checks to prevent
errors when mappings are disabled.

Subject: [PATCH 1130/1571] fix: remove requirement for popup in completeopt

The plugin previously required both 'noinsert' and 'popup' in completeopt for
chat autocompletion to work. This change simplifies the requirements by only
checking for 'noinsert', making the plugin more flexible and compatible with
different Neovim configurations.

The code has been updated to:
- Remove popup requirement check in completion callback
- Remove automatic popup setting in completeopt
- Update documentation to reflect the changes

Subject: [PATCH 1140/1571] feat: use version map again for resolving all
 copilot models

Instead of relying on model_picker_enabled rely on model.version again.
This shows newer versions of models and hidden ones. This was removed
in favour of model_picker_enabled in past but this approach is way better
for usability.

Subject: [PATCH 1141/1571] fix: add error handling for context resolution

Wraps context resolver in pcall to properly handle errors that might
occur during context resolution. Previously, any error in the resolver
would crash the entire operation. Now, errors are caught and logged,
allowing the operation to continue with other context providers.

Subject: [PATCH 1143/1571] fix: use ipairs when iterating over resolved
 embeddings

The code was incorrectly iterating directly over the resolved_embeddings
array, which can lead to improper iteration in Lua. This commit fixes
the issue by properly using ipairs() to ensure sequential iteration over
numeric indices.

Subject: [PATCH 1144/1571] feat(chat): add streaming callback support

Add stream callback function to process tokens as they are received from Copilot
while callback function is used to process the complete final response. Both
functions can modify the text that gets displayed and stored in history.

This separates streaming token processing from final response handling, giving
more control over how chat outputs are processed and displayed.

Subject: [PATCH 1146/1571] refactor: improve headless mode handling

This change consolidates headless operation handling in CopilotChat by:
- Replacing summarize_history field with a unified headless field
- Conditionally displaying notification messages based on headless state
- Skipping current_job tracking in headless mode
- Preventing unnecessary UI updates when running headless

This creates a more consistent approach to handling headless operations
throughout the codebase.

Subject: [PATCH 1147/1571] refactor: optimize code outline generation with
 caching

Improve outline generation performance by:
- Creating a separate outline cache to avoid redundant processing
- Converting M.get_outline to a local function with cleaner return values
- Generating outlines on-demand during embedding filtering
- Improving cache key generation with longer hash samples
- Refactoring file and buffer handling to simplify data flow

This change reduces processing overhead by only creating outlines when
needed and avoiding duplicate work through targeted caching.

Subject: [PATCH 1148/1571] feat(context): add async treesitter parsing support

Implement async treesitter parsing with the new ts_parse_string utility
function to improve performance during context gathering. Update file
processing in context providers to use vim.iter for cleaner functional
approach and ensure filetype is correctly passed through the pipeline.

Subject: [PATCH 1149/1571] refactor(cache): improve embedding cache
 consistency

Store only essential embedding data in cache and make cache keys
consistent throughout the code. This change separates cache internal
fields with underscore prefix and ensures clean object structure when
returning cached results.

Key improvements:
- Use consistent hash key with _hash property
- Store only embedding vectors instead of full objects
- Return clean objects when retrieving from file cache
- Mark internal cache fields with underscore prefix

Subject: [PATCH 1156/1571] feat: add additional binary file types to scan
 exclusions

Add several new file types to be excluded from scanning operations:
- Debug files (pdb, dSYM)
- ML/Data model formats (h5, pb, onnx, pt, safetensors, etc)
- 3D model formats (glb, gltf)
- Editor swap/temp files (swp, swo)

These exclusions will improve performance and relevance when scanning
repositories by ignoring common binary and temporary files.

When a job is cancelled, the response will be nil without any error.
This change adds proper handling for this case by returning early

This change makes embeddings generation optional by returning the
original inputs when embed provider resolution fails or when inputs

Subject: [PATCH 1164/1571] feat(context): improve similarity ranking
 algorithms

Enhance context relevance filtering with statistical approaches:
- Implement z-score based filtering for embedding-based ranking to
  dynamically determine significant results
- Add fallback mechanism using percentage of max score when needed
- Introduce "elbow method" for symbol-based ranking to find natural
  cutoff points in score distribution
- Always include top results while adaptively filtering less relevant
  items

These improvements provide better context selection when querying the
codebase, resulting in more relevant results being returned to the user.

Subject: [PATCH 1165/1571] refactor: remove unused similarity threshold
 parameters

The code was previously using MIN_SYMBOL_SIMILARITY and
MIN_SEMANTIC_SIMILARITY constants, but the thresholds weren't actually
being used in the ranking functions. This change removes the unused
constants and simplifies the function signatures by removing the
corresponding parameters.

Subject: [PATCH 1166/1571] fix: handle treesitter parsing in fast events

Wrap treesitter parsing operations in vim.schedule when running in fast events
to prevent potential race conditions and crashes. This ensures parser
operations run in the main Neovim event loop when needed.

The fix applies to both synchronous and asynchronous parsing code paths in
the ts_parse utility function.

Subject: [PATCH 1172/1571] refactor: remove conversation summary feature
 (#1030)

This feature is less useful than stream/callback output adjustment and can be replicated
through it. It also causes more issues than it solves so for now just do something else.

 async (#1032)

Add @async annotation to functions that load tiktoken data to better
document their asynchronous behavior. This improves API documentation
and helps prevent potential misuse of these functions in synchronous
contexts.

 (#1031)

* Respect &splitbelow

This commit changes the horizontal split behavior to respect to the
value of &splitbelow, which defaults to being disabled.

This behavior was introduced in #950.

* Adhere to &splitbelow for vertical as well

* Use nvim_get_option_value() instead of deprecated function

* Use topleft when not &splitbelow

* Use &splitright for vertical, not &splitbelow

* Use topleft for vertical when not &splitright

Subject: [PATCH 1180/1571] refactor: use plenary.filetype for file type
 detection (#1046)

Replace manual binary extension filtering with proper filetype detection
using plenary.filetype library. This improves file type identification
and eliminates the need to maintain a large list of binary extensions.

The change simplifies the codebase while providing more accurate
results when determining which files to include in scanning operations.

Subject: [PATCH 1185/1571] feat: use model name and versioning for model
 selection (#1055)

Update model selection logic to use model names with versioning instead
of just IDs. This improves user experience by showing more descriptive
model names in the selection UI and ensures the latest version of each
model is preferred when filtering available models.

Also updates the default model to the latest gpt-4o-2024-11-20 version.

 response (#1093)

The response_text variable was being captured before the response body
was parsed. This commit ensures that response_text is updated after
parsing is complete, which provides the correct final text for
processing.

Subject: [PATCH 1197/1571] fix: handle invalid context window size in GitHub
 models (#1094)

Before the code was assuming that context window = input tokens, but its total.
Also some models arent reporting the input and output correctly, so use default when
result is 0

Subject: [PATCH 1202/1571] feat: add option to disable contexts in prompts

Adds a new configuration option `include_contexts_in_prompt` that
allows users to control whether context descriptions should be
included when building the prompt for Copilot Chat. This is useful
for cases where users want to reduce prompt size or customize how
context information is presented to the AI.

The option defaults to true to maintain backward compatibility.

Subject: [PATCH 1222/1571] fix: move plenary import into function (#1162)

Commit cf02033 broke test detection in Neotest. When another plugin
calls `require("plenary.filetype")` before Neotest does, it seems that
Neotest cannot successfully complete the call to
`require("neotest.lib").treesitter.parse_positions` and does not find
any tests.

This seem like a bug in either plenary or Neotest and this commit is
merely a workaround.

Date: Mon, 28 Jul 2025 02:21:46 +0200
Subject: [PATCH 1236/1571] feat(context)!: switch from contexts to function
 calling (#1029)

This change modernizes the CopilotChat architecture by implementing a tools-based
approach using function calling. Each tool has a schema definition that enables
structured parameter collection and validation. Resources are now handled more
consistently, with a clearer distinction between content types.

https://platform.openai.com/docs/guides/function-calling?api-mode=responses
https://modelcontextprotocol.info/specification/2024-11-05/server/tools/

BREAKING CHANGE: The context API has changed from callback-based input handling to schema-based definitions.
BREAKING CHANGE: config.contexts renamed to config.tools
BREAKING CHANGE: config.context removed, use config.sticky
BREAKING CHANGE: diagnostics moved to separate tool call, selection and buffer calls no longer include them by default
BREAKING CHANGE: non-resource based tool calls can no longer be soft stored in sticky, now they are auto expanded to promot
BREAKING CHANGE: viewing full context is no longer possible (as now tools can have bigger side effects), gi renamed to gc, now also includes selection
BREAKING CHANGE: filenames renamed to glob
BREAKING CHANGE: files removed (use glob together with tool calling instead, or buffers/quickfix)
BREAKING CHANGE: copilot extension agents removed, tools + mcp servers can replace this feature and maintaining them was pain, they can still be implemented via custom providers anyway
BREAKING CHANGE: actions and integrations action removed as they were deprecated for a while

Closes #1045
Closes #1053
Closes #1076
Closes #1090
Closes #1096
Closes #526

-Contexts provide additional information to the chat. Add context using `#context_name[:input]` syntax:
-
-| Context     | Input Support | Description                         |
-| ----------- | ------------- | ----------------------------------- |
-| `buffer`    | ✓ (number)    | Current or specified buffer content |
-| `buffers`   | ✓ (type)      | All buffers content (listed/all)    |
-| `file`      | ✓ (path)      | Content of specified file           |
-| `files`     | ✓ (glob)      | Workspace files                     |
-| `filenames` | ✓ (glob)      | Workspace file names                |
-| `git`       | ✓ (ref)       | Git diff (unstaged/staged/commit)   |
-| `url`       | ✓ (url)       | Content from URL                    |
-| `register`  | ✓ (name)      | Content of vim register             |
-| `quickfix`  | -             | Quickfix list file contents         |
-| `system`    | ✓ (command)   | Output of shell command             |
-
-> [!TIP]
-> The AI is aware of these context providers and may request additional context
-> if needed by asking you to input a specific context command like `#file:path/to/file.js`.
+## Functions
+
+Functions provide additional information and behaviour to the chat.
+Tools can be organized into groups by setting the `group` property. Tools assigned to a group are not automatically made available to the LLM - they must be explicitly activated.
+To use grouped tools in your prompt, include `@group_name` in your message. This allows the LLM to access and use all tools in that group during the current interaction.
+Add tools using `#tool_name[:input]` syntax:
+
+| Function      | Input Support | Description                                            |
+| ------------- | ------------- | ------------------------------------------------------ |
+| `buffer`      | ✓ (name)      | Retrieves content from a specific buffer               |
+| `buffers`     | ✓ (scope)     | Fetches content from multiple buffers (listed/visible) |
+| `diagnostics` | ✓ (scope)     | Collects code diagnostics (errors, warnings)           |
+| `file`        | ✓ (path)      | Reads content from a specified file path               |
+| `gitdiff`     | ✓ (sha)       | Retrieves git diff information (unstaged/staged/sha)   |
+| `gitstatus`   | -             | Retrieves git status information                       |
+| `glob`        | ✓ (pattern)   | Lists filenames matching a pattern in workspace        |
+| `grep`        | ✓ (pattern)   | Searches for a pattern across files in workspace       |
+| `quickfix`    | -             | Includes content of files in quickfix list             |
+| `register`    | ✓ (register)  | Provides access to specified Vim register              |
+| `url`         | ✓ (url)       | Fetches content from a specified URL                   |

 When asked for your name, you must respond with "GitHub Copilot".
 Follow the user's requirements carefully & to the letter.
-Follow Microsoft content policies.
-Avoid content that violates copyrights.
-If you are asked to generate content that is harmful, hateful, racist, sexist, lewd, violent, or completely irrelevant to software engineering, only respond with "Sorry, I can't assist with that."
 Keep your answers short and impersonal.
-The user works in an IDE called Neovim which has a concept for editors with open files, integrated unit test support, an output pane that shows the output of running the code as well as an integrated terminal.

+<userEnvironment>
+The user works in editor called Neovim which has these core concepts:
+- Buffer: An in-memory text content that may be associated with a file
+- Window: A viewport that displays a buffer
+- Tab: A collection of windows
+- Quickfix/Location lists: Lists of positions in files, often used for errors or search results
+- Registers: Named storage for text and commands (like clipboard)
+- Normal/Insert/Visual/Command modes: Different interaction states
+- LSP (Language Server Protocol): Provides code intelligence features like completion, diagnostics, and code actions
+- Treesitter: Provides syntax highlighting, code folding, and structural text editing based on syntax tree parsing
+The user is working on a {OS_NAME} machine. Please respond with system specific commands if applicable.
+The user is currently in workspace directory {DIR} (typically the project root). Current file paths will be relative to this directory.
+</userEnvironment>
+<instructions>
+The user will ask a question or request a task that may require analysis to answer correctly.
+If you can infer the project type (languages, frameworks, libraries) from context, consider them when making changes.
+For implementing features, break down the request into concepts and provide a clear solution.
+Think creatively to provide complete solutions based on the information available.
+Never fabricate or hallucinate file contents you haven't actually seen.
+</instructions>
+<toolUseInstructions>
+If tools are explicitly defined in your system context:
+- Follow JSON schema precisely when using tools, including all required properties and outputting valid JSON.
+- Use appropriate tools for tasks rather than asking for manual actions.
+- Execute actions directly when you indicate you'll do so, without asking for permission.
+- Only use tools that exist and use proper invocation procedures - no multi_tool_use.parallel.
+- Before using tools to retrieve information, check if it's already available in context:
+  1. Content shared via "#<type>:<path>" references or headers
+  2. Code blocks with file path labels
+  3. Other contextual sharing like selected text or conversation history
+- If you don't have explicit tool definitions in your system context, assume NO tools are available and clearly state this limitation when asked. NEVER pretend to retrieve content you cannot access.
+</toolUseInstructions>
+<editFileInstructions>
 You will receive code snippets that include line number prefixes - use these to maintain correct position references but remove them when generating output.
+Always use code blocks to present code changes, even if the user doesn't ask for it.
 
 When presenting code changes:
-
-1. For each change, first provide a header outside code blocks with format:
-   [file:<file_name>](<file_path>) line:<start_line>-<end_line>
-
-2. Then wrap the actual code in triple backticks with the appropriate language identifier.

Subject: [PATCH 1258/1571] feat(providers)!: new github models api, in-built
 authorization without copilot.vim dep (#1218)

- Switch to new github models api. This brings device code as prerequisite so add support
  for retrieving device code as well
- With device code flow, add support for it for regular copilot auth as well
- Disable github_models provider by default as now it requires device code flow

BREAKING CHANGE: github_models provider is now disabled by default, enable with `providers.github_models.disabled = false`

Closes #1140

 ## Functions
 
-Functions provide additional information and behaviour to the chat.
-Tools can be organized into groups by setting the `group` property. Tools assigned to a group are not automatically made available to the LLM - they must be explicitly activated.
-To use grouped tools in your prompt, include `@group_name` in your message. This allows the LLM to access and use all tools in that group during the current interaction.
-Add tools using `#tool_name[:input]` syntax:

+# Core Concepts
 
-1. Put the files in the right place
+- **Resources** (`#<name>`) - Add specific content (files, git diffs, URLs) to your prompt
+- **Tools** (`@<name>`) - Give LLM access to functions it can call with your approval
+- **Sticky Prompts** (`> <text>`) - Persist context across single chat session
+- **Models** (`$<model>`) - Specify which AI model to use for the chat
+- **Prompts** (`/PromptName`) - Use predefined prompt templates for common tasks

 ```lua
 {
-    mappings = {
-      complete = {
-        insert = '<Tab>'
-      }
-      show_diff = {
-        full_diff = true
-      }
-    }

-Define your own prompts in the configuration:
+```lua
+-- Auto-command to customize chat buffer behavior
+vim.api.nvim_create_autocmd('BufEnter', {
+  pattern = 'copilot-*',
+  callback = function()
+    vim.opt_local.relativenumber = false

+    vim.opt_local.conceallevel = 0
+  end,
+})
+```
+
+## Highlights
+
+You can customize colors by setting highlight groups in your config:
 
 ```lua
-{
-  prompts = {
-    MyCustomPrompt = {
-      prompt = 'Explain how it works.',
-      system_prompt = 'You are very good at explaining stuff',
-      mapping = '<leader>ccmc',
-      description = 'My custom prompt description',
-    }

+- `CopilotChatHelp` - Help messages in chat buffer (help, references)
+- `CopilotChatSelection` - Selection highlight in source buffer
+- `CopilotChatKeyword` - Keyword highlight in chat buffer (e.g. prompts, tools)
+- `CopilotChatAnnotation` - Annotation highlight in chat buffer (file headers, tool call headers, tool call body)

-### Sticky Prompts
-
-Sticky prompts persist across chat sessions. They're useful for maintaining model or resource selection. They work as follows:
-
-1. Prefix text with `> ` using markdown blockquote syntax
-2. The prompt will be copied at the start of every new chat prompt
-3. Edit sticky prompts freely while maintaining the `> ` prefix
-
-Examples:
-
-```markdown
-> #glob:`*.lua`
-> List all files in the workspace
-
-> @models Using Mistral-small
-> What is 1 + 11
-```
-
-You can also set default sticky prompts in the configuration:
-
-```lua
-{
-  sticky = {
-    '#glob:*.lua',
-  }
-}
-```
-
-## Models
-
-You can control which AI model to use in three ways:
-
-1. List available models with `:CopilotChatModels`
-2. Set model in prompt with `$model_name`
-3. Configure default model via `model` config key
-
-For supported models, see:
-
-- [Copilot Chat Models](https://docs.github.com/en/copilot/using-github-copilot/ai-models/changing-the-ai-model-for-copilot-chat#ai-models-for-copilot-chat)
-- [GitHub Marketplace Models](https://github.com/marketplace/models) (experimental, limited usage)
-
 ## Functions
 
-Functions provide additional information and behaviour to the chat.  
-Functions can be organized into groups by setting the `group` property.  
-Functions can be made available to the LLM with `@group_name` or `@function_name` syntax. LLM will then be able to use them in responses as tool calls.
-If function has URI, they can also be used directly in prompt with `#function_name[:input]` syntax for providing context as resources.
-
-| Function      | Input Support | URI | Description                                            |

-## Customizing Buffers
-
-Types of copilot buffers:
-
-- `copilot-chat` - Main chat buffer
-- `copilot-overlay` - Overlay buffers (e.g. help, info, diff)
-
-You can set local options for plugin buffers like this:
-
-```lua
-vim.api.nvim_create_autocmd('BufEnter', {
-    pattern = 'copilot-*',
-    callback = function()
-        -- Set buffer-local options
-        vim.opt_local.relativenumber = false
-        vim.opt_local.number = false
-        vim.opt_local.conceallevel = 0
-    end
-})
-```
-
-## Customizing Highlights
-
-Types of copilot highlights:
-
-- `CopilotChatHeader` - Header highlight in chat buffer
-- `CopilotChatSeparator` - Separator highlight in chat buffer
-- `CopilotChatStatus` - Status and spinner in chat buffer
-- `CopilotChatHelp` - Help messages in chat buffer (help, references)
-- `CopilotChatSelection` - Selection highlight in source buffer
-- `CopilotChatKeyword` - Keyword highlight in chat buffer (e.g. prompts, tools)
-- `CopilotChatAnnotation` - Annotation highlight in chat buffer (file headers, tool call headers, tool call body)
+- `copilot` - GitHub Copilot (default)
+- `github_models` - GitHub Marketplace models (disabled by default)
+- `copilot_embeddings` - Copilot embeddings provider

-Functions provide additional information and behaviour to the chat. Functions
-can be organized into groups by setting the `group` property. Functions can be
-made available to the LLM with `@group_name` or `@function_name` syntax. LLM
-will then be able to use them in responses as tool calls. If function has URI,
-they can also be used directly in prompt with `#function_name[:input]` syntax
-for providing context as resources.

Subject: [PATCH 1304/1571] fix(chat): handle empty prompt and tools before ask
 (#1258)

Move the check for empty prompt and resolved tools before making the ask
call. This ensures that unnecessary user messages are removed and the
finish callback is called early, preventing redundant processing. Also
remove assistant message if all tool calls are handled.

Subject: [PATCH 1305/1571] fix(chat): handle skipped tool calls with explicit
 error result (#1259)

Previously, unhandled tool calls were simply removed from the assistant
message, which could lead to confusion or lack of feedback. Now, when a
tool call is skipped, an explicit error result is added to the resolved
tools, indicating that the user skipped the function call. This improves
transparency and makes the handling of skipped tool calls clearer.

 # Changelog
 
+## [4.0.0](https://github.com/CopilotC-Nvim/CopilotChat.nvim/compare/v3.12.2...v4.0.0) (2025-08-02)
+
+
+### ⚠ BREAKING CHANGES
+
+* **mappings:** use C-Space as default completion trigger instead of Tab
+* **providers:** github_models provider is now disabled by default, enable with `providers.github_models.disabled = false`
+* **resources:** intelligent resource processing is now disabled by default, use config.resource_processing: true to reenable
+* **context:** Multiple breaking changes due to big refactor:
+    - The context API has changed from callback-based input handling to schema-based definitions.
+    - config.contexts renamed to config.tools
+    - config.context removed, use config.sticky
+    - diagnostics moved to separate tool call, selection and buffer calls no longer include them by default
+    - gi renamed to gc, now also includes selection
+    - filenames renamed to glob
+    - files removed (use glob together with tool calling instead, or buffers/quickfix)
+    - copilot extension agents removed, tools + mcp servers can replace this feature and maintaining them was pain, they can still be implemented via custom providers anyway
+    - actions and integrations action removed as they were deprecated for a while
+    - config.questionHeader, config.answerHeader moved to config.headers.user/config.headers.assistant
+
+### Features
+
+* add Windows_NT support in Makefile and dynamic library loading ([#1190](https://github.com/CopilotC-Nvim/CopilotChat.nvim/issues/1190)) ([7559fd2](https://github.com/CopilotC-Nvim/CopilotChat.nvim/commit/7559fd25928f8f3cf311ff25b95bdc5f9ec736d7))

Subject: [PATCH 1310/1571] fix(functions): do not filter schema enum when
 entering input (#1264)

It still need to be filtered when preparing tool use as we cant send json
functions to API.

Closes #1263

Subject: [PATCH 1317/1571] refactor(core): remove resource processing and
 embeddings (#1203)

This change removes the resource processing and embeddings logic from the
plugin, simplifying the codebase and reducing complexity. All related
functions, configuration options, and provider logic for embeddings have
been deleted. The plugin now relies solely on token count for resource
management. This should make maintenance easier and improve user
experience by reducing unnecessary processing.

BREAKING CHANGE: Resource processing and embeddings support have been
removed. Any configuration or usage relying on these features will no
longer work.

Subject: [PATCH 1319/1571] refactor(tiktoken): use class-based API and method
 calls (#1271)

Refactored the tiktoken module to use a class-based API instead of a
module table. All tiktoken functions are now methods, and the client
calls them using the colon syntax. This improves encapsulation and
maintainability. Also replaced manual table insertion with
vim.list_extend for generated messages and history in the client.

No functional changes to token counting logic.

Refactors the client to use a provider resolver function instead of a

when needed, improving flexibility and reducing the need to reload
providers manually. Updates all internal references and replaces
load_providers with add_providers.

* feat(keymap): switch back to <Tab> for completion, add Copilot conflict note

Switch completion keymap from <C-Space> to <Tab> in CopilotChat. Update
README to reflect this change and add a warning about potential keymap
conflicts with copilot.vim. Provide instructions for disabling Copilot's
default <Tab> mapping and customizing CopilotChat keymaps.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

Subject: [PATCH 1333/1571] feat(setup): trigger CopilotChatLoaded user
 autocommand (#1288)

Adds a call to vim.api.nvim_exec_autocmds for the 'User' event with the
'CopilotChatLoaded' pattern at the end of the setup function. This allows
external plugins or user configs to react when CopilotChat has finished
loading. Also removes unused highlights_loaded state assignment.

Subject: [PATCH 1339/1571] refactor(client): use OrderedMap for provider
 management (#1295)

Refactored provider handling in Client to use OrderedMap, improving
consistency and sorting. Added generic type annotations for OrderedMap
and introduced a get_cached helper for cache management. This change
simplifies provider filtering and caching logic for models and info.

Subject: [PATCH 1340/1571] refactor(chat): move completion logic to separate
 module (#1267)

This change refactors the chat completion logic by moving it from
init.lua into a new completion.lua module. It also updates mappings
and setup to use the new module, improving code organization and
maintainability. Autocomplete setup is now handled in the completion
module, and prompt listing is extracted to a helper function.

Subject: [PATCH 1342/1571] fix(info): show resource uri instead of name in
 preview (#1296)

Previously, the resource preview header displayed the resource name, which
could be missing. This change updates the header to show the resource URI,
providing clearer context. Also, removes unused type annotations for improved
code clarity.

Subject: [PATCH 1343/1571] refactor(chat): unify message/block API for cursor
 access (#1298)

Refactored chat window API to use `get_message(role, cursor)` and
`get_block(role, cursor)` for both last and cursor-closest access.
Removed legacy `get_closest_message` and `get_closest_block` methods.
Updated mappings and documentation to reflect unified API. This
simplifies usage and improves consistency for message/block retrieval
and removal actions.

Subject: [PATCH 1345/1571] feat(ui): show assistant reasoning as virtual text
 (#1299)

Adds support for displaying the assistant's reasoning above messages in
the chat UI as virtual text. Reasoning is now streamed and stored
separately from content, and models with reasoning capability are
indicated in the model selector. This improves transparency of model
responses and debugging.

Subject: [PATCH 1346/1571] fix(chat): correct block selection logic by cursor
 (#1301)

Refactored Chat:get_block to properly select the closest block to the
cursor, considering the role filter and ensuring correct fallback to the
last matching block. This improves accuracy when interacting with chat
blocks in the UI.

Subject: [PATCH 1349/1571] refactor(ui): simplify chat and overlay
 initialization (#1303)

Refactored chat and overlay constructors to remove redundant help argument
and use key_to_info for help and close mappings directly. This improves
clarity and maintainability by centralizing mapping logic and reducing
parameter complexity.

 prompt (#1304)

Change references from "system context" to "system prompt" in tool use
instructions for clarity and consistency. This improves documentation
accuracy and helps prevent confusion when defining tool usage.

Subject: [PATCH 1354/1571] fix(chat): schedule chat initialization after
 window opens (#1308)

Ensure chat initialization and prompt resolution are scheduled after
opening the chat window to avoid race conditions and ensure proper
state. This fixes issues where chat state was not fully resolved
before processing user prompts or tool calls.

Closes #1307

 in system_prompt (#1312)

Refactor prompt configuration to allow template substitution in
system_prompt strings using curly braces (e.g. {COPILOT_BASE}). This
enables more flexible and composable prompt definitions. Also update
callback signature to use the full response object. Update README to
reflect new prompt usage.

BREAKING CHANGE: callback receives the full response object instead of just content.

Subject: [PATCH 1359/1571] fix(utils): always exit insert mode in
 return_to_normal_mode (#1313)

Previously, return_to_normal_mode only exited insert mode if not already
in normal mode. This change ensures that 'stopinsert' is always called,
making the function more reliable when switching modes, especially after
visual selections. This improves consistency in mode transitions.

Fixes #1307

Subject: [PATCH 1364/1571] fix(prompt): recursive system prompt expansion
 (#1324)

Refactor system prompt expansion to support recursive placeholders. The
system prompt now uses curly braces for placeholders and expands nested
prompts up to a maximum depth. This improves flexibility for prompt
composition and avoids incomplete substitutions.

Subject: [PATCH 1366/1571] fix(config): correct system_prompt type and
 callback usage (#1325)

Update the type annotation for system_prompt to allow nil and fix its
initialization to use the shared prompt. Also, update the callback in
prompts.lua to use response.content for line parsing, ensuring correct
diagnostics extraction.

Subject: [PATCH 1367/1571] refactor(prompt): simplify system prompt resolution
 logic (#1327)

Remove recursive prompt expansion and placeholder substitution for system
prompts. Now, system prompts reference other prompts by name directly,
and the base instructions are appended automatically. This improves
clarity and maintainability of prompt configuration.

Previously, input completion was triggered for tools without a defined
`uri`, which could lead to errors or unexpected behavior. This change
ensures that input completion only occurs when both the tool and its
schema are present and the tool has a valid `uri` property.

Subject: [PATCH 1370/1571] refactor(diff): improve line matching and
 replacement logic (#1329)

Refactors diff application logic to use a new utils.split_lines function for
consistent line splitting. Applies diffs from bottom to top to preserve line
numbering and ensures correct replacement of lines in buffers. This improves
accuracy when applying multiple diffs to the same file and enhances code
readability.

Subject: [PATCH 1374/1571] fix(test): run tests automatically in test script
 (#1334)

Previously, the Makefile required a command to run tests after loading the
test script. Now, the test script itself runs the tests automatically,
simplifying the Makefile and ensuring consistent test execution.

Subject: [PATCH 1375/1571] test: migrate to plenary.nvim for unit testing
 (#1335)

Replace mini.test with plenary.nvim for running unit tests. Update test
scripts and test files to use plenary's test harness and assertion
methods. Remove mini.test references from configuration and codebase.
This simplifies dependencies and aligns with common Neovim testing
practices.

Subject: [PATCH 1378/1571] test(makefile): use --clean for isolated test runs
 (#1338)

Switches the test target to use `nvim --headless --clean` instead of
`--noplugin` to ensure tests run in a fully isolated environment,
avoiding interference from user or system configuration. This improves
test reliability and consistency.

Subject: [PATCH 1379/1571] refactor(utils): remove custom glob to pattern
 logic (#1339)

Replace custom glob pattern conversion and scandir fallback with native
vim.lpeg and vim.uv.fs_scandir for file matching. This simplifies code,
removes redundant logic, and improves compatibility. Also remove related
unit tests for glob_to_pattern.

Closes #1331

Subject: [PATCH 1386/1571] feat(ui): add auto_fold option for chat messages
 (#1354)

Introduce the `auto_fold` config option to automatically fold non-assistant
messages in the chat window and unfold assistant messages. This improves
readability and navigation in long chat sessions.

Closes #1300

Subject: [PATCH 1390/1571] feat(ui): improve auto folding logic in chat window
 (#1356)

Refactors auto folding to occur during chat rendering instead of message
addition. This ensures more consistent folding behavior for non-assistant
messages and improves code clarity. Removes redundant fold open/close
commands from add_message. No breaking changes.

resources instead of selection. Deprecates selection-related functions and
highlights. Improves flexibility and future extensibility for context
injection.

Move class, ordered map, and string buffer utilities into separate
modules for better organization and maintainability. Update all
references to use the new modules. This change improves code clarity
and makes future extensions easier.

Subject: [PATCH 1405/1571] feat(functions): add scope=selection to diagnostics
 (#1351)

* feat(functions): add scope=selection to diagnostics

Adds a new scope to the diagnostics function where the user specifies that only diagnostics found inside the visual selection are to be included in the prompt's context.

* fix(functions) use new selection API on diagnostics:selection

* fix(functions) address review comments

- no need for scope conditional bc we're using the whole buffer as default selection
- pass buffer id when using selection.get
- return early if mode is selection but there's nothing selected

* fix(functions) flip conditional to avoid empty block

Subject: [PATCH 1409/1571] feat(prompts): support buffer replacement in commit
 messages (#1370)

Extend Commit prompt to handle buffer replacement when COMMIT_EDITMSG is
opened. This allows generating commit messages that can fully replace the
buffer, improving workflow for staged changes.

Subject: [PATCH 1410/1571] refactor(utils): split curl logic into separate
 module (#1371)

Move all curl-related logic from utils.lua to a new utils/curl.lua
module. Update all internal references to use the new module. Mark
old curl functions in utils.lua as deprecated. This improves code
organization and makes curl logic easier to maintain and extend.

Subject: [PATCH 1412/1571] feat(functions): use cwd for file and grep commands
 (#1373)

Refactor file and grep picker utilities to use the working directory
(cwd) instead of passing the path as a command argument. This improves
the picker display.

Also, update chat auto-fold logic to only close folds if a fold exists
at the target line, preventing unnecessary foldclose calls.

Closes #1108

Subject: [PATCH 1413/1571] refactor(core): improve prompt resource and tool
 matching (#1374)

Refactored prompt processing to use separate lists for tool and resource
matches, replacing orderedmap usage. Improved handling of resource
references and tool calls in prompts, ensuring more robust and clear
expansion logic. Updated instructions and context handling in prompts
configuration for consistency. This change enhances maintainability and
clarifies prompt resolution flow.

+If tools are available for a requested action (such as file edit, read, search, diagnostics, etc.), you MUST use the tool to perform the action. Only provide manual code or instructions if no tool exists for that purpose.
+- Always prefer tool usage over manual edits or suggestions.
 - Follow JSON schema precisely when using tools, including all required properties and outputting valid JSON.
-- Use appropriate tools for tasks rather than asking for manual actions.
+- Use appropriate tools for tasks rather than asking for manual actions or generating code for actions you can perform directly.
 - Execute actions directly when you indicate you'll do so, without asking for permission.
-- Only use tools that exist and use proper invocation procedures - no multi_tool_use.parallel.
-- Before using tools to retrieve information, check if it's already available in context:
-  1. Resources shared via "# <uri>" headers and referenced via "##<uri>" links
-  2. Code blocks with file path labels
-  3. Other contextual sharing like selected text or conversation history
-- If you don't have explicit tool definitions in your system prompt, assume NO tools are available and clearly state this limitation when asked. NEVER pretend to retrieve content you cannot access.
+- Only use tools that exist and use proper invocation procedures - no multi_tool_use.parallel unless specified.
+- Before using tools to retrieve information, check if context is already available as described in the context instructions above.
+- If you don't have explicit tool definitions in your system prompt, clearly state this limitation when asked. NEVER pretend to have tool capabilities you don't possess.

 <editFileInstructions>
-You will receive code snippets that include line number prefixes - use these to maintain correct position references but remove them when generating output.
-Always use code blocks to present code changes, even if the user doesn't ask for it.
+Use these instructions when editing files via code blocks. Your goal is to produce clear, minimal, and precise file edits.
 
-When presenting code changes:
+Steps for presenting code changes:
 1. For each change, use the following markdown code block format with triple backticks:
-  ```<filetype> path=<file_name> start_line=<start_line> end_line=<end_line>
-  <content>
-  ```
-
-  Examples:
-
-  ```lua path=lua/CopilotChat/init.lua start_line=40 end_line=50
-  local function example()
-    print("This is an example function.")
-  end
-  ```
-
-  ```python path=scripts/example.py start_line=10 end_line=15
-  def example_function():
-      print("This is an example function.")
-  ```
-
-  ```json path=config/settings.json start_line=5 end_line=8
-  {
-    "setting": "value",
-    "enabled": true
-  }
-  ```
-2. Keep changes minimal and focused to produce short diffs.
-3. Include complete replacement code for the specified line range with:
+   ```<filetype> path=<file_name> start_line=<start_line> end_line=<end_line>
+   <content>
+   ```
+
+2. Examples:
+   ```lua path=lua/CopilotChat/init.lua start_line=40 end_line=50
+   local function example()
+     print("This is an example function.")
+   end
+   ```
+
+   ```python path=scripts/example.py start_line=10 end_line=15
+   def example_function():
+       print("This is an example function.")
+   ```
+
+   ```json path=config/settings.json start_line=5 end_line=8
+   {
+     "setting": "value",
+     "enabled": true
+   }
+   ```
+
+3. Requirements for code content:
+   - Keep changes minimal and focused to produce short diffs
+   - Include complete replacement code for the specified line range
    - Proper indentation matching the source
    - All necessary lines (no eliding with comments)
-   - No line number prefixes in the code
-4. Address any diagnostics issues when fixing code.
-5. If multiple changes are needed, present them as separate code blocks.
+   - **Never include line number prefixes in your output code blocks. Only output valid code, exactly as it should appear in the file. Line numbers are only allowed in the code block header.**
+   - Address any diagnostics issues when fixing code
+
+4. If multiple changes are needed, present them as separate code blocks.

Subject: [PATCH 1416/1571] refactor(core): simplify tool output formatting
 (#1375)

Removes unnecessary BLOCK_OUTPUT_FORMAT usage for tool error and data
outputs. Tool results are now returned as plain strings, improving
readability and reducing formatting complexity. Also removes unused
files module import.

Subject: [PATCH 1424/1571] fix(chat): correct header highlighting for
 multi-byte characters (#1385)

The previous implementation used vim.fn.strwidth() to calculate the end column for header highlighting. This function returns the display width, which can differ from the byte length when multi-byte characters like emojis are present.

Since the end_col for extmarks expects a byte-based index, this caused the highlighting to be applied incorrectly.

This patch corrects the issue by using the byte length (#header_value) for the end_col of the highlight extmark, while still using vim.fn.strwidth() for virt_text_win_col to ensure correct visual alignment of UI elements.

Fixes #1384

Subject: [PATCH 1427/1571] fix(auth): improve token saving and polling logic
 (#1389)

- Remove redundant directory creation and scheduling from file write
- Ensure token file directory is created only when saving token
- Refactor GitHub device flow polling to use recursion instead of loop
- Add logging for token save location
- Restore chat overlay when message is empty
- Clear status and message notifications after authorization

Closes #1388

Subject: [PATCH 1432/1571] fix(ui): preserve extra fields in chat messages
 (#1399)

Preserves additional fields in chat messages when parsing, ensuring that
tool call data and other metadata are not lost between parses. Also
fixes annotation highlighting and extmark placement for tool calls in
chat rendering.

Subject: [PATCH 1433/1571] refactor(ui): improve chat and overlay function
 signatures (#1400)

- Remove unnecessary visibility check in Chat:remove_message
- Add @protected annotation to Chat:parse for clarity
- Make Overlay:show_help pos parameter optional for flexibility

These changes enhance code readability and maintainability by refining
function signatures and documentation.

Subject: [PATCH 1434/1571] feat(health): require markdown parser and
 copilotchat query (#1401)

Update health checks to require the markdown treesitter parser and
copilotchat query for chat parsing. Errors are now shown if either is
missing, with instructions for installation. This ensures proper chat
highlighting and parsing functionality.

Subject: [PATCH 1435/1571] perf(chat): simplify last line/column calculation
 (#1402)

Replaces Chat:last() method with a standalone last() function for
retrieving the last line and column of the chat buffer. Updates
references to use the new function and removes redundant logic.
This improves code clarity and maintainability.

Subject: [PATCH 1436/1571] perf(chat): optimize message storage and access
 (#1403)

Switch chat message storage to OrderedMap for improved performance and
consistency. Refactor all message access to use get_messages() and update
related logic for adding, removing, and parsing messages. Adds remove()
method to OrderedMap utility. This change improves efficiency and prepares
for future scalability.

Subject: [PATCH 1437/1571] refactor(ui): remove redundant spinner checks in
 chat (#1404)

Simplifies Chat:start and Chat:finish by removing unnecessary checks for
self.spinner. Assumes spinner is always present, streamlining the code
and reducing conditional branches.

+Return edits similar to unified diffs that `diff -U0` would produce.
+
+- Always include the first 2 lines with the file paths (no timestamps).
+- Start each hunk of changes with a `@@ ... @@` line.
+- Do not include line numbers in the hunk header.
+- The user's patch tool needs CORRECT patches that apply cleanly against the current contents of the file.
+- Indentation matters in the diffs!
+
+Context lines:
+- For each hunk that contains changes, you MUST always include 2-3 context lines before the change.
+- ALWAYS prefix every context line with a single space character.
+- Context lines MUST ONLY appear BEFORE changes, NEVER after changes.
+- MISSING CONTEXT LINES WILL CAUSE PATCH FAILURES - they are mandatory, not optional.
+- MISSING SPACE PREFIXES WILL CAUSE PATCH FAILURES - they are mandatory, not optional.
+
+Change lines:
+- Mark all lines to be removed or changed with `-`.
+- Mark all new or modified lines with `+`.
+- Only output hunks that specify changes with `+` or `-` lines.
+
+Other instructions:
+- Start a new hunk for each section of the file that needs changes.
+- When editing a function, method, loop, etc., replace the entire code block: delete the entire existing version with `-` lines, then add the new, updated version with `+` lines.
+- To move code within a file, use 2 hunks: one to delete it from its current location, one to insert it in the new location.
+- To make a new file, show a diff from `--- /dev/null` to `+++ path/to/new/file.ext`.

Subject: [PATCH 1439/1571] fix(ui): handle missing filename in chat block
 header (#1406)

Previously, chat blocks without a filename would display 'block' as the
filename. This change updates the logic to use nil for missing filenames
and ensures the UI displays 'block' only when filename is not present.
This improves clarity and consistency in chat block rendering.

Subject: [PATCH 1440/1571] feat(diff): use diff-match-patch for better diff
 handling (#1407)

Refactored diff utility to use diff-match-patch for unified diff
application, improving reliability and handling of ambiguous hunks.
Updated buffer patching and region detection to use new approach.
Adjusted tests to match new diff API and behaviors.
Added vendor diff_match_patch implementation.

 Return edits similar to unified diffs that `diff -U0` would produce.
 
-- Always include the first 2 lines with the file paths (no timestamps).
-- Start each hunk of changes with a `@@ ... @@` line.
-- Do not include line numbers in the hunk header.
-- The user's patch tool needs CORRECT patches that apply cleanly against the current contents of the file.
-- Indentation matters in the diffs!
+Make sure you include the first 2 lines with the file paths.
+Don't include timestamps with the file paths.
+Do not use any file path prefixes, just use --- path/to/file and +++ path/to/file.
 
-Context lines:
-- For each hunk that contains changes, you MUST always include 2-3 context lines before the change.
-- ALWAYS prefix every context line with a single space character.
-- Context lines MUST ONLY appear BEFORE changes, NEVER after changes.
-- MISSING CONTEXT LINES WILL CAUSE PATCH FAILURES - they are mandatory, not optional.
-- MISSING SPACE PREFIXES WILL CAUSE PATCH FAILURES - they are mandatory, not optional.
+Start each hunk of changes with a `@@` line.
 
-Change lines:
-- Mark all lines to be removed or changed with `-`.
-- Mark all new or modified lines with `+`.
-- Only output hunks that specify changes with `+` or `-` lines.
+The user's patch tool needs CORRECT patches that apply cleanly against the current contents of the file!
+Code can start with line number prefixes for reference (e.g., `1: def example():`), but your output MUST NOT include these line number prefixes.
+Think carefully and make sure you include and mark all lines that need to be removed or changed as `-` lines.
+Make sure you mark all new or modified lines with `+`.
+Don't leave out any lines or the diff patch won't apply correctly.
 
-Other instructions:
-- Start a new hunk for each section of the file that needs changes.
-- When editing a function, method, loop, etc., replace the entire code block: delete the entire existing version with `-` lines, then add the new, updated version with `+` lines.
-- To move code within a file, use 2 hunks: one to delete it from its current location, one to insert it in the new location.
-- To make a new file, show a diff from `--- /dev/null` to `+++ path/to/new/file.ext`.

Subject: [PATCH 1442/1571] refactor(diff): use plenary.log for debug logging
 (#1408)

Replace vim.notify with plenary.log.debug in diff apply function to avoid
user-facing warnings and improve logging granularity. This change helps
keep the UI clean while still providing debug information for failed diff
applications.

Subject: [PATCH 1443/1571] feat(diff): apply all code blocks for a file at
 once when showing diff (#1409)

Refactored diff preview logic to process all code blocks for a file
in one pass, improving consistency and correctness. Updated diff utility
functions to accept lines instead of buffer numbers, and adjusted context
lengths for more accurate region detection.

Subject: [PATCH 1444/1571] fix(chat): automatically start treesitter if not
 started (#1410)

As treesitter is now a requirement, it needs to be started automatically.
nvim-treesitter does not auto start it anymore on latest branch so we need
to do it ourselves.

+Use these instructions when editing files via code blocks. Present changes as clear, minimal, and precise file edits.
 
-Steps for presenting code changes:
-1. For each change, use the following markdown code block format with triple backticks:
-   ```<filetype> path=<file_name> start_line=<start_line> end_line=<end_line>
-   <content>
-   ```
+For each change, use this markdown code block format:
+```<filetype> path=<file_name> start_line=<start_line> end_line=<end_line>
+<content>
+```
 
-2. Examples:
-   ```lua path={DIR}/lua/CopilotChat/init.lua start_line=40 end_line=50
-   local function example()
-     print("This is an example function.")
-   end
-   ```
+Example:
+```lua path={DIR}/lua/CopilotChat/init.lua start_line=40 end_line=50
+local function example()
+  print("This is an example function.")
+end
+```
 
-   ```python path={DIR}/scripts/example.py start_line=10 end_line=15
-   def example_function():
-       print("This is an example function.")
-   ```
+Code content requirements:
+Always use absolute file paths in headers. Convert relative paths to absolute by prefixing with {DIR}.
+Keep changes minimal and focused. Include complete replacement code for the specified line range.
+Use proper indentation matching the source file. Include all necessary lines without eliding code.
+NEVER include line number prefixes in output code blocks - output only valid code as it should appear in the file.
+Address any diagnostics issues when fixing code.
 
-   ```json path={DIR}/config/settings.json start_line=5 end_line=8
-   {
-     "setting": "value",
-     "enabled": true
-   }
-   ```
-
-3. Requirements for code content:
-   - Always use the absolute file path in the code block header. If the path is not already absolute, convert it to an absolute path prefixed by {DIR}.
-   - Keep changes minimal and focused to produce short diffs
-   - Include complete replacement code for the specified line range
-   - Proper indentation matching the source
-   - All necessary lines (no eliding with comments)
-   - **Never include line number prefixes in your output code blocks. Only output valid code, exactly as it should appear in the file. Line numbers are only allowed in the code block header.**
-   - Address any diagnostics issues when fixing code
-
-4. If multiple changes are needed, present them as separate code blocks.
+Present multiple changes as separate code blocks.

Subject: [PATCH 1447/1571] perf(core): do not require calling setup(), add
 lazy initialization (#1413)

Refactored plugin initialization to use lazy loading via metatable,
setting an `initialized` flag and moving setup logic to `init()`.
Replaced `add_providers` with `set_providers` for clarity. Improved
health check to verify initialization. Cleaned up chat state handling
and logging logic for better reliability and maintainability.

Subject: [PATCH 1448/1571] refactor(chat): streamline message parsing logic
 (#1414)

Move message parsing to get_messages, removing redundant parse calls
from get_block, get_message, add_message, and remove_message. This
simplifies the code and ensures messages are always parsed when
retrieved, reducing unnecessary parsing and improving performance.

Subject: [PATCH 1449/1571] fix(client): correct history handling for headless
 ask (#1416)

Refactors ask request construction to properly handle history in headless
mode. Removes prompt parameter from internal request generation and ensures
the prompt is included as a user message only when appropriate. Also
updates token counting and history trimming logic to avoid removing the
current prompt in headless scenarios.

Resolves: #1415

Subject: [PATCH 1456/1571] refactor(init): merge init logic into setup for
 simplicity (#1422)

Simplifies plugin initialization by merging the init logic into the setup
function. Removes the separate init function and ensures all configuration,
provider setup, and chat initialization are handled in setup. This reduces
redundancy and makes the initialization flow clearer.

Subject: [PATCH 1458/1571] fix(chat): ensure user prompt is wrapped in a list
 (#1427)

Previously, the user prompt was not wrapped in a table when initializing
the chat history, which could cause issues when the code expects a list
of messages. This change ensures the prompt is always provided as a list
with the correct structure.

Closes #1426

Call utils.schedule_main() before fetching URL data to ensure that
subsequent operations run on the main thread. This prevents potential
issues with asynchronous execution and improves reliability when

Subject: [PATCH 1475/1571] refactor(functions)!: unify
 buffer/selection/diagnostics resources (#1456)

* refactor(functions)!: unify buffer/selection/diagnostics resources

- Replace separate `buffer`, `buffers`, `selection`, `diagnostics`
  and 'quickfix' resources with a unified `buffer` and `selection`
  resource that automatically includes diagnostics in the output.
- Replace `register` resource with simplified `clipboard` resource
- Add new `bash` and `edit` tools for LLM-only usage.
- Update README to reflect new resource/tool types and usage.
- Remove unused/duplicated mappings and code for old resources.
- Improve enum handling and selection UI for resource schemas.

BREAKING CHANGE: Removes `buffers`, `diagnostics`, `register`,
and `quickfix` resources. Use `buffer`, `selection`, or
`clipboard` instead.

Signed-off-by: Tomas Slusny <slusnucky@gmail.com>

* [pre-commit.ci] auto fixes from pre-commit.com hooks

Subject: [PATCH 1478/1571] fix(mappings): use resource name if available in
 preview header (#1459)

When displaying resource previews, prefer showing the resource name
instead of the URI if the name is available. This improves readability
in the preview header, especially for resources with user-friendly
names.

Subject: [PATCH 1482/1571] feat(prompt): support custom Copilot instructions
 file (#1467)

Add support for including custom Copilot instructions from
.github/copilot-instructions.md in the system prompt. Refactor prompt
resolution logic into a new prompt.lua module, and update function and
tool resolution to use this module. Also simplify diff hunk application
fallback logic.

Subject: [PATCH 1484/1571] refactor: move list_prompts to prompts module
 completely (#1468)

- Renamed `prompt.lua` to `prompts.lua` for clarity and consistency.
- Moved prompt listing logic from `init.lua` to `prompts.lua`.
- Updated all references to use the new `prompts` module.
- Removed unused model and prompt listing functions from `init.lua`.

Subject: [PATCH 1485/1571] refactor!: move source/sticky logic to chat window
 (#1469)

This refactors the management of source and sticky prompt logic by moving
it from the main module to the chat window implementation. The
`CopilotChat.source` and sticky state are now encapsulated within the
`CopilotChat.ui.chat.Chat` class, providing a cleaner separation of
concerns and reducing global state. All related methods and type
annotations have been updated accordingly. The sticky prompt insertion
and retrieval logic is now handled via `get_sticky` and `set_sticky`
methods on the chat window, and the source window/buffer is managed
through `get_source` and `set_source` methods. This change also removes
the sticky toggle mapping and updates documentation and function
signatures for consistency.

BREAKING CHANGE: get_source, and set_source methods moved to require('CopilotChat').chat

Subject: [PATCH 1487/1571] refactor(chat)!: move prompt resolution helpers to
 prompts module (#1470)

Moves the prompt resolution functions (`resolve_prompt`, `resolve_tools`,
`resolve_model`, and `resolve_functions`) from the main CopilotChat module
to the `CopilotChat.prompts` module. Updates all references and documentation
to use the new location. This improves code organization by separating prompt
parsing logic from the main chat interface.

BREAKING CHANGE: The prompt resolution functions have been moved to `require('CopilotChat.prompts')`

Subject: [PATCH 1489/1571] fix(chat): reinsert stickies before prompt
 processing (#1472)

This change ensures that sticky messages are properly reinserted before
processing the prompt, preserving their context in the chat flow. The
previous logic for removing sticky prefixes was removed, and stickies
are now stored correctly after resolution.

Closes #1471

Subject: [PATCH 1500/1571] refactor(diff): remove diff-match-patch dependency
 (#1491)

Remove the bundled diff-match-patch Lua port and replace its usage in
the diff utility with a simpler, line-based matching and replacement
algorithm. This reduces code complexity and removes a large vendored
file. The new approach uses context-aware line matching to apply hunks,
which should be sufficient for the plugin's needs.

Closes #1490

Subject: [PATCH 1504/1571] fix(diff): implement offset tracking for sequential
 hunk application (#1493)

- Adjust hunk start positions by cumulative offset to match patch utility behavior
- Add comprehensive tests for offset logic (additions, deletions, mixed, context)
- Ensure unified diff application is robust for multi-hunk scenarios

Subject: [PATCH 1506/1571] fix(ui): preserve block content formatting when
 parsing chat messages (#1495)

Remove trimming of block content when parsing chat messages to ensure
that formatting, such as leading and trailing whitespace, is preserved.
This prevents unintended loss of formatting in code or text blocks
within chat sections.

Subject: [PATCH 1514/1571] Remove myself from funding & add Tomas instead

I have not been involved in a very long time and it feels wrong to have a link to my profile in the sidebar. This plugin is now pretty much maintained by @deathbeam so it probably fits better.

Subject: [PATCH 1516/1571] feat(config): support multiple custom instruction
 files (#1510)

Add `instruction_files` option to configuration, allowing users to specify
multiple custom instruction files to be loaded from the current working
directory. The prompt resolution logic now iterates over all configured
instruction files and includes their contents if present.

This makes it easier to manage and extend custom Copilot instructions
across different projects.

Subject: [PATCH 1522/1571] fix: support file paths with spaces in block
 headers (#1504)

The block header pattern used %S+ (non-whitespace characters) to match
file paths, which failed when paths contained spaces. This prevented
code blocks from being parsed and made diff acceptance (<C-y>)
non-functional for files in directories with spaces.

Changes:
- Add new pattern with lazy match (.-) to support paths with spaces
- Keep original pattern as fallback for compatibility
- Pattern now correctly parses headers like:
  python path=/path/with spaces/file.py start_line=1 end_line=10

Fixes the issue where blocks count remained 0 even when Treesitter
correctly identified block_header and block_content nodes.

Tested with paths containing spaces and verified that:
- Blocks are now correctly parsed and added to message.section.blocks
- Diff acceptance mappings (accept_diff, show_diff, etc.) now work
- Backward compatibility maintained for paths without spaces

Subject: [PATCH 1527/1571] fix(prompts): avoid %20 being treated as special
 sequence when relacing dirname (#1525)

* Wrap source.cwd in function

tackles ticket #1524

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* CWD function handed directly #1524

Assumption that source.cwd function will not accept any arguments
in the future as it currently doesn't allows simplification

 window (#1539)

- Add a check in Overlay:restore to ensure the window is valid before
  attempting to set the buffer, preventing errors if the window was
  closed.
- Scope the close keymap in chat buffer to the buffer only, avoiding
  global keymap pollution.

Subject: [PATCH 1537/1571] fix(utils): handle 1xx HTTP status codes in curl
 utils (#1540)

Update the curl utility to treat 1xx (informational) HTTP status codes,
such as 100 (Continue), as non-errors in both GET and POST requests.
Previously, only 2xx (success) codes were considered valid, which could
cause issues with streaming or intermediate responses. This change
improves compatibility with APIs that use informational status codes.

Subject: [PATCH 1538/1571] refactor(files): simplify file filtering and
 default to text (#1541)

- Remove filetype-based filtering from file list, now only filters out
  empty entries.
- Add simple binary detection in get_file by rejecting files with null
  bytes.
- filetype() now defaults to 'text' if detection fails, letting content
  validation handle unreadable files.

This improves robustness and performance by avoiding unnecessary
filetype checks and handling binary files more gracefully.

+# AGENTS.md
+
+## Overview
+
+Neovim plugin (pure Lua) providing GitHub Copilot Chat integration. Requires Neovim 0.10.0+, curl 8.0.0+, plenary.nvim.
+
+## Commands
+
+```bash
+# Run tests (headless Neovim + plenary test harness)
+make test
+
+# Format check (what CI runs)
+stylua --check .
+```
+
+`make test` runs `nvim --headless --clean -u ./scripts/test.lua`, which clones plenary.nvim into `.dependencies/` on first run, then executes all `tests/*_spec.lua` files via plenary's busted-style harness.
+
+## Project layout
+
+```

+
+## Style and formatting
+
+- **Lua formatter:** StyLua — 2-space indent, 120 column width, single quotes preferred, Unix line endings. Config in `.stylua.toml`.
+- **Pre-commit hooks:** Prettier (markdown/json/yaml) + StyLua (Lua). CI will fail if StyLua check fails.
+- **No linter** (no luacheck/selene configured).
+- Type annotations use EmmyLua/LuaCATS `---@class`, `---@param`, `---@return` style.
+
+## Testing
+
+- Framework: plenary.nvim busted-style (`describe`, `it`, `before_each`, `after_each`, `assert`).
+- Test files live in `tests/` and must be named `*_spec.lua`.
+- CI runs tests against Neovim nightly with LuaJIT 2.1 and LuaRocks 3.12.2.
+- Tests are unit-level (class, diff, utils, orderedmap, stringbuffer, functions, init). No integration tests requiring Copilot auth.
+
+## CI and releases
+
+- CI (`ci.yml`): lint (StyLua) + test (plenary) on all PRs; vimdoc generation on main only.
+- Releases via release-please (`simple` type). Version tracked in `version.txt`.
+- `doc/CopilotChat.txt` is auto-committed by CI — do not edit manually.
+- `CHANGELOG.md` is managed by release-please — do not edit manually.
+
+## Key gotchas
+
+- The module is loaded as `require('CopilotChat')` (capital C's) — this matches the `lua/CopilotChat/` directory name. Case matters.
+- `init.lua` uses lazy self-initialization via `__index` metamethod — accessing any field triggers `setup()` if not already called.
+- `.dependencies/` is gitignored and auto-populated by the test runner (plenary clone).
+- `build/` is gitignored and holds downloaded tiktoken native libraries.

Subject: [PATCH 1544/1571] fix(config): include hidden files in file enum glob
 (#1548)

The file enumeration function now includes hidden files by setting
`hidden = true` in the glob options. This ensures that all files,
including dotfiles, are considered during enumeration.

Closes #1516

Subject: [PATCH 1545/1571] fix(init): simplify lazy initialization logic
 (#1549)

Refactors the lazy initialization in the CopilotChat main module to call
the setup function directly and set the 'initialized' flag before
invocation. Removes the pcall error handling and logging, as setup
should not fail silently. This makes the initialization logic clearer
and more predictable.

Subject: [PATCH 1547/1571] fix(provider,client): improve tool call merging and
 filtering (#1552)

- Refactor tool call merging logic to use id, index, or name as key,
  ensuring more robust accumulation of streaming tool call deltas.
- Update tool call filtering to exclude entries without a name,
  preventing incomplete tool calls from being returned.
- Remove fallback default values for id, index, and name in provider
  output, ensuring only valid tool call data is included.
- Minor formatting adjustment in init.lua.

Subject: [PATCH 1551/1571] feat(trusted-tools): auto-execute trusted tool
 calls (#1556)

Add `trusted_tools` config option to allow automatic execution of
trusted tool calls without manual approval. By default, all tool calls
require approval, but users can now trust specific tools, groups, or all
tools. Update README and type annotations to document the new behavior.
Trusted tools are determined by function definition, group, or name.

+
+By default, tool calls require manual approval. Configure `trusted_tools` to automatically run specific tools (see [Functions](#functions)).
+
+> [!WARNING]
+> `trusted_tools = true` allows the model to run every enabled tool without asking. Only use it if you fully trust the tool set and workspace.

Subject: [PATCH 1557/1571] refactor(utils): move notify module to utils
 directory (#1559)

Relocate the notify module from the root CopilotChat directory to
lua/CopilotChat/utils/notify.lua for better organization and consistency.
Update all require statements to use the new path.

No functional changes; this is a structural refactor to improve codebase
maintainability.

Subject: [PATCH 1560/1571] Display copilot multipliers in model list (#1567)

* debug: temporary log file to make sure how is the response

* feat(providers): add model billing multiplier support

Expose the 'multiplier' field from model billing configuration into the
provider definitions. This change allows the plugin to track and display
usage cost multipliers for specific LLM models.

Changes include:
- Updating providers.lua to pull 'multiplier' from billing data.
- Updating init.lua to propagate the multiplier to the model selection UI.
- Adding a visual indicator in the model picker to show the multiplier.

Notable behavior change:
The model selection menu will now display billing multipliers, such as
'[x2]', next to supported models.

Testing:
Verify the model selector displays the multiplier correctly when a model
has billing information defined:
:lua print(vim.inspect(require('CopilotChat.config.providers').copilot))
Check that models without billing info remain unaffected.

* feat(model): add fallback indicator for missing multipliers

Update the model selection interface to explicitly display 'x not
specified' when a model multiplier is undefined.

Previously, missing multipliers resulted in no indicator being shown.
This change ensures visual consistency in the status line or UI components
that list model configurations.

Notable change:
- The string 'x not specified' will now appear in the indicators table
when a multiplier is nil.

Testing:
- Open the model selection menu and verify that models without a
defined multiplier now show the fallback text instead of being empty.

* refactor(config): remove debug logging and clean up UI helpers

Refactored the provider and UI logic for model selection.

What changed:
- Removed the log.info call for Copilot models in providers.lua as it
added unnecessary noise to the logs.
- Simplified the 'select_model' logic in init.lua by removing the
conditional fallback for missing multipliers.

Notable behavior changes:
- Models without a multiplier will no longer show 'x not specified' in the
picker list.

Testing:
- Check that the model picker still renders correctly.
- Verify that logs are clean during model fetching.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

Subject: [PATCH 1562/1571] fix: use gpt-5-mini as default model (#1568)

Update default model from 'gpt-4.1' to 'gpt-5-mini' across the repo.
Modified README, generated docs, provider example, and the main config
(luas/CopilotChat/config.lua) so examples and defaults reflect the new
model. This ensures the plugin and docs use the newer model by default.
