Tool Use: From Tool Choice to PTC
Tool choice (Auto / Any / Force)

Tool choice (Auto / Any / Force)

Covers how to configure tool selection, and why prompt design matters as much as tool_choice itself.

  • Upstream notebook: tool_use/tool_choice.ipynb

What to focus on

  • tool_choice={"type":"auto"} for selective usage
  • Forcing a specific tool when you need deterministic behavior
  • “Any” mode tradeoffs (more freedom, more risk)
