+
+## Chat Mappings
+
+- `` - Trigger completion menu for special tokens or accept current completion (see help)
+- `q`/`` - Close the chat window
+- `` - Reset and clear the chat window
+- ``/`` - Submit the current prompt
+- `gr` - Toggle sticky prompt for the line under cursor
+- `` - Accept nearest diff (works best with `COPILOT_GENERATE` prompt)
+- `gj` - Jump to section of nearest diff. If in different buffer, jumps there; creates buffer if needed (works best with `COPILOT_GENERATE` prompt)
+- `gq` - Add all diffs from chat to quickfix list
+- `gy` - Yank nearest diff to register (defaults to `"`)
+- `gd` - Show diff between source and nearest diff
+- `gi` - Show info about current chat (model, agent, system prompt)
+- `gc` - Show current chat context
+- `gh` - Show help message
+
+The mappings can be customized by setting the `mappings` table in your configuration. Each mapping can have:
+
+- `normal`: Key for normal mode
+- `insert`: Key for insert mode
+- `detail`: Description of what the mapping does
+
+For example, to change the submit prompt mapping:
+
+```lua
+{
+ mappings = {
+ submit_prompt = {
+ normal = 's',
+ insert = ''
+ }
+ }
+}
+```
+
+## Prompts
+
+You can ask Copilot to do various tasks with prompts. You can reference prompts with `/PromptName` in chat or call with command `:CopilotChat`.
+Default prompts are:
+
+- `Explain` - Write an explanation for the selected code 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
+
+You can define custom prompts like this (only `prompt` is required):
+
+```lua
+{
+ prompts = {
+ MyCustomPrompt = {
+ prompt = 'Explain how it works.',
+ system_prompt = 'You are very good at explaining stuff',
+ mapping = 'ccmc',
+ description = 'My custom prompt description',
+ }
+ }
+}
+```
-#### Commands coming from default prompts
+## System Prompts
-- `:CopilotChatExplain` - Explain how it works
-- `:CopilotChatTests` - Briefly explain how selected code works then generate unit tests
-- `: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 readablilty.
-- `:CopilotChatDocs` - Write documentation for the selected code. The reply should be a codeblock containing the original code with the documentation added as comments. Use the most appropriate documentation style for the programming language used (e.g. JSDoc for JavaScript, docstrings for Python etc.
-- `:CopilotChatFixDiagnostic` - Please assist with the following diagnostic issue in file
-- `:CopilotChatCommit` - Write commit message for the change with commitizen convention
-- `:CopilotChatCommitStaged` - Write commit message for the change with commitizen convention
+System prompts specify the behavior of the AI model. You can reference system prompts with `/PROMPT_NAME` in chat.
+Default system prompts are:
-### API
+- `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
+
+You can define custom system prompts like this (works same as `prompts` so you can combine prompt and system prompt definitions):
+
+```lua
+{
+ prompts = {
+ Yarrr = {
+ system_prompt = 'You are fascinated by pirates, so please respond in pirate speak.',
+ }
+ }
+}
+```
+
+## 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
+```
+
+## 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.
+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 or default agent via config using `agent` key.
+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 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).
+- `buffers` - Includes all buffers in chat context. Supports input (default listed).
+- `file` - Includes content of provided file in chat context. Supports input.
+- `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).
+ - `git:unstaged` - Includes unstaged changes in chat context.
+ - `git:staged` - Includes staged changes in chat context.
+- `url` - Includes content of provided URL in chat context. Supports input.
+- `register` - Includes contents of register in chat context. Supports input (default +, e.g clipboard).
+
+You can define custom contexts like this:
+
+```lua
+{
+ contexts = {
+ birthday = {
+ input = function(callback)
+ vim.ui.select({ 'user', 'napoleon' }, {
+ prompt = 'Select birthday> ',
+ }, callback)
+ end,
+ resolve = function(input)
+ input = input or 'user'
+ local birthday = input
+ if input == 'user' then
+ birthday = birthday .. ' birthday is April 1, 1990'
+ elseif input == 'napoleon' then
+ birthday = birthday .. ' birthday is August 15, 1769'
+ end
+
+ return {
+ {
+ content = birthday,
+ filename = input .. '_birthday',
+ filetype = 'text',
+ }
+ }
+ end
+ }
+ }
+}
+```
+
+```markdown
+> #birthday:user
+
+What is my birthday
+```
+
+## 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).
+Selection includes content, start and end position, buffer info and diagnostic info (if available).
+Supported selections that live in `local select = require("CopilotChat.select")` are:
+
+- `select.visual` - Current visual selection.
+- `select.buffer` - Current buffer content.
+- `select.line` - Current line content.
+- `select.unnamed` - Unnamed register content. This register contains last deleted, changed or yanked content.
+
+You can chain multiple selections like this:
+
+```lua
+{
+ selection = function(source)
+ return select.visual(source) or select.buffer(source)
+ end
+}
+```

-PREREQUISITES *CopilotChat-copilot-chat-for-neovim-prerequisites*
-
-Ensure you have the following installed:
-
-- **Neovim stable (0.9.5) or nightly**.
-
-Optional:
-
-- tiktoken_core: `sudo luarocks install --lua-version 5.1 tiktoken_core`. Alternatively, download a pre-built binary from lua-tiktoken releases
-- You can check your Lua PATH in Neovim by doing `:lua print(package.cpath)`. Save the binary as `tiktoken_core.so` in any of the given paths.
+==============================================================================
+1. Requirements *CopilotChat-requirements*
+
+- Neovim 0.9.5+ - Older versions are not supported, and for best compatibility 0.10.0+ is preferred
+- curl - 8.0.0+ is recommended for best compatibility. Should be installed by default on most systems and also shipped with Neovim
+- Copilot chat in the IDE setting enabled in GitHub settings
+- _(Optional)_ tiktoken_core - Used for more accurate token counting
+ - For Arch Linux users, you can install `luajit-tiktoken-bin` or `lua51-tiktoken-bin` from aur
+ - Alternatively, install via luarocks: `sudo luarocks install --lua-version 5.1 tiktoken_core`
+ - Alternatively, download a pre-built binary from lua-tiktoken releases . You can check your Lua PATH in Neovim by doing `:lua print(package.cpath)`. Save the binary as `tiktoken_core.so` in any of the given paths.
+- _(Optional)_ git - Used for fetching git diffs for `git` context
+ - For Arch Linux users, you can install `git` from the official repositories
+ - For other systems, use your package manager to install `git`. For windows use the installer provided from git site
+- _(Optional)_ lynx - Used for improved fetching of URLs for `url` context
+ - For Arch Linux users, you can install `lynx` from the official repositories
+ - For other systems, use your package manager to install `lynx`. For windows use the installer provided from lynx site
+
+
+ [!WARNING] If you are on neovim < 0.11.0, you also might want to add `noinsert`
+ and `popup` to your `completeopt` to make the chat completion behave well.

+SYSTEM PROMPTS *CopilotChat-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:
-API ~
+- `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
+
+You can define custom system prompts like this (works same as `prompts` so you
+can combine prompt and system prompt definitions):
+
+>lua
+ {
+ prompts = {
+ Yarrr = {
+ system_prompt = 'You are fascinated by pirates, so please respond in pirate speak.',
+ }
+ }
+ }
+<
+
+
+STICKY PROMPTS *CopilotChat-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
+<
+
+
+MODELS *CopilotChat-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. 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
+
+You can use more models from here by
+using `@models` agent from here
+(example: `@models Using Mistral-small, what is 1 + 11`)
+
+
+AGENTS *CopilotChat-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 or default agent via config
+using `agent` key. Default "noop" agent is `copilot`.
+
+For more information about extension agents, see here
+
+You can install more agents from here
+
+
+
+CONTEXTS *CopilotChat-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).
+- `buffers` - Includes all buffers in chat context. Supports input (default listed).
+- `file` - Includes content of provided file in chat context. Supports input.
+- `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).
+ - `git:unstaged` - Includes unstaged changes in chat context.
+ - `git:staged` - Includes staged changes in chat context.
+- `url` - Includes content of provided URL in chat context. Supports input.
+- `register` - Includes contents of register in chat context. Supports input (default +, e.g clipboard).
+
+You can define custom contexts like this:
+
+>lua
+ {
+ contexts = {
+ birthday = {
+ input = function(callback)
+ vim.ui.select({ 'user', 'napoleon' }, {
+ prompt = 'Select birthday> ',
+ }, callback)
+ end,
+ resolve = function(input)
+ input = input or 'user'
+ local birthday = input
+ if input == 'user' then
+ birthday = birthday .. ' birthday is April 1, 1990'
+ elseif input == 'napoleon' then
+ birthday = birthday .. ' birthday is August 15, 1769'
+ end
+
+ return {
+ {
+ content = birthday,
+ filename = input .. '_birthday',
+ filetype = 'text',
+ }
+ }
+ end
+ }
+ }
+ }
+<
+
+>markdown
+ > #birthday:user
+
+ What is my birthday
+<
+
+
+SELECTIONS *CopilotChat-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). Selection
+includes content, start and end position, buffer info and diagnostic info (if
+available). Supported selections that live in `local select =
+require("CopilotChat.select")` are:
+
+- `select.visual` - Current visual selection.
+- `select.buffer` - Current buffer content.
+- `select.line` - Current line content.
+- `select.unnamed` - Unnamed register content. This register contains last deleted, changed or yanked content.
+
+You can chain multiple selections like this:
+
+>lua
+ {
+ selection = function(source)
+ return select.visual(source) or select.buffer(source)
+ end

-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?

-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.
+2. *DO NOT* include any explanations, comments, or line numbers in your response.
-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.
+3. Ensure the returned code is complete and can be directly used as a replacement for the original code.
-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.
+4. Preserve the original structure, indentation, and formatting of the code as much as possible.
-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.
+5. *DO NOT* omit any parts of the code, even if they are unchanged.
