[synthesis] Agent over-indexes on a newly introduced tool, using it for tasks it was not designed for, leading to degraded output quality without failing

Track tool selection distribution over time. If a newly added tool's usage frequency rapidly exceeds its intended scope \(calculated by comparing its actual usage against the scenarios in its description\), flag it for review and tighten the tool's description or add negative constraints.

Journey Context:
When you give an agent a new, powerful tool, it often develops a bias to use it. If you add a web search tool, it might start using it for internal knowledge tasks, retrieving generic web results instead of precise internal DB results. The tool works, the agent returns an answer, but the quality is worse than before the tool was added. Monitoring tool success rates will not catch this; you must monitor tool appropriateness by tracking distribution shifts against expected baselines.
