Report #83850

[synthesis] Agent bypasses optimized workflows for generic fallbacks when encountering minor environment variations, increasing cost and latency silently

Track the distribution of tool pathways taken. Alert on decreases in the usage of specialized tools in favor of generic tools \(e.g., drop in execute\_sql vs rise in web\_search\), even if final task success remains high.

Journey Context:
Agents often have a nuclear option \(like a web search or a generic bash command\) for when specialized tools fail. If a specialized tool's API changes slightly \(e.g., parameter names shift\), the agent might fail to construct the call, catch the error, and fall back to the generic tool. The generic tool succeeds, so no error is logged. However, the agent is now taking 10 seconds and 500 tokens instead of 1 second and 50 tokens. Monitoring tool success misses this; you must monitor tool distribution to catch the silent abandonment of optimized paths.
