Calculator tool

Implements a minimal “tool loop” using a calculator tool, showing how tools + tool_use blocks connect to real code execution.

• Upstream notebook: tool_use/calculator_tool.ipynb

What to focus on

• Tool schema shape: name / description / input_schema
• Tool execution in your app (not inside the model)
• Returning results back as tool_result linked by tool_use_id

Run locally

make test-notebooks NOTEBOOK=tool_use/calculator_tool.ipynb

Next

• If tool selection matters, continue with ../tool-choice
• If you need multiple tools per turn, continue with ../parallel-tools
