Lmstudio and local models need system prompt #2463
Description
I am running on OSX with lmstudio.
I am using qwen3-coder-30b-0-a3-instruct
- the model does not have a system prompt telling it how to use tools
- I cant find what system prompt or instructions, I am supposed to give model
- It cannot find the LSP server commands
The model claims it can find and execute the following commands.
Based on my exploration of the opencode environment, here's what I can determine about the tool API:
Available Tools in Opencode Environment
- Bash - Execute shell commands
- Read - Read file contents
- Write - Write to files
- Edit - Modify existing files
- Glob - Find files by pattern
- Grep - Search file contents
- List - List directory contents
- WebFetch - Fetch web content
It claims the tools are invoked with JSON.
It claims it cannot create sub-agents, because it does not have access to an API.
It also claims it cannot use LSP because there is no API documentation.
Is there a system prompt or some list of tools, that I am supposed to provide the LLM?

This issue might be a duplicate of existing issues. Please check:
Feel free to ignore if none of these address your specific case.

There are no lsp tools rn so this is expected
There should be a tool called “task” it can use for subagents

No I would expect things to work out of the box can you share what happens? Are tools not invoking? Does it say it has none?

Yes. The LLM fights with me and claims its not a development environment and it has no tools to edit files.
I can setup an automated environment and try different local LLMs and send evals.
You should definitely contact me about a fine tune or model merge or something; and producing some open source models tuned for toolset.
Sonnet was good but the other models, fight with you and refuse to use tools or do software development.

@haltingstate the only people i hear having this issue have some misconfiguration with their setup that prevents model from using tools properly.
if you ask the llm what tools it has what does it say?
Do you have any special AGENTS.md prompt or anything else?

Let me try again.
Issue may have been fixed.
Opencode and Crush are on same code base, so was surprised I had such a large difference in behavior from Opencode.
I will open a new ticket if it come back.
