[research] Changing tool descriptions or schemas silently breaks agent tool selection

Version your tool schemas and descriptions in version control. Run a targeted regression eval suite that specifically tests tool-selection accuracy \(given prompt X, does the agent call tool Y?\) whenever a tool definition is modified.

Journey Context:
LLMs are highly sensitive to tool names and descriptions. A minor wording change in a docstring can cause the agent to hallucinate parameters or select the wrong tool. Standard integration tests don't catch this because the code executes, but the LLM's choice changes. Isolating tool-selection evals decouples logic testing from semantic routing testing.
