    <Step title="Select the Claude deployment">
      Deploy Claude Sonnet 4.6 in the resource named by `ANTHROPIC_FOUNDRY_RESOURCE`. This variable takes the resource name, not the full endpoint URL. Set `ANTHROPIC_FOUNDRY_API_KEY` to that resource's key.

      The source assumes the deployment is named `claude-sonnet-4-6`. If you chose another name, replace the model's `id` with your deployment name while retaining the other model settings. See [Claude deployment and inference setup](https://learn.microsoft.com/en-us/azure/foundry/foundry-models/how-to/use-foundry-models-claude).

  <Step title="Run the example">
    Save the code above as `tool_use.py`, then run:

    ```bash
    python tool_use.py
