Report #68179

[research] Agent selects the wrong tool or hallucinates tool parameters, causing runtime exceptions

Create an eval suite specifically for tool selection and parameter extraction. Test the LLM with the system prompt and available tool schemas, providing only the user query, and assert the correct tool call JSON.

Journey Context:
End-to-end evals make it hard to distinguish whether the agent failed at reasoning or at tool formatting. By isolating the tool-selection step, you can quickly diagnose if the tool descriptions are ambiguous or if the model struggles with complex JSON schemas. This is much cheaper and faster than running full agent loops for debugging tool misuse.
