Report #68764

[research] Agent accidentally achieves the right result using the wrong tool \(e.g., reading a file via shell cat instead of the file API\)

Include exact tool-name matching or tool-parameter schema validation in your eval rubric. Do not rely solely on outcome-based evals if tool usage has security or cost implications.

Journey Context:
Outcome-based evals \(just checking if the final answer is right\) miss severe security and compliance risks. An agent using rm and recreating a file instead of editing it is a regression. Explicitly evaluating the tool selection step ensures the agent follows the intended, safe architecture.
