timeout to any question

[XiaobinZhao]

after pip install .i ask many questions, all answer final is: timeout

[lsdefine]

Hi, this is most likely caused by the model you're using being too weak — it's hallucinating XML-style tool calls (like <tool_use>, <timeout>) instead of producing valid JSON tool-call format.

Suggestions:

1. Switch to a stronger model (e.g. Claude Sonnet 4, GPT-4o, Gemini 2.5 Pro, etc.). Weaker models tend to hallucinate invalid tool call formats.
2. If you want to keep using your current model, you can try adding a hint in the system prompt or just say to it to remind it that tool calls must be in JSON format, not XML. But note that if the model is too weak, it may still not follow this instruction.

The framework expects the model to output structured JSON tool calls. When a model instead outputs raw XML text like <timeout>, the framework cannot parse it, leading to the timeout you're seeing.

This has been addressed — we now recommend using native tool_use mode (function calling) instead of relying on weaker models to produce XML-style tool calls. Additionally, llmcore.py includes a fallback parser (_parse_text_tool_calls) that can handle XML-style <tool_use>/<tool_call> tags as a safety net, plus MixinSession auto-retry across multiple backends.

Closing as resolved.
