[synthesis] Agent brute-forces through updated API responses via retries, resulting in degraded data quality

Track the ratio of tool retries to successful calls. Alert on any increase in the retry-to-success ratio, even if the ultimate success rate remains high, and log the exact schema of the tool response to detect contract drift.

Journey Context:
When an external API changes its response format \(e.g., adding a pagination wrapper or renaming a field\), an agent with robust retry logic might eventually extract the data it needs by trying different parsing strategies or falling back to regex. The agent succeeds and returns data, but it might miss crucial new fields or take 5 retries instead of 1. The success metric is unchanged, but latency and data completeness degrade. Monitoring retry ratios catches the contract drift before the brute-force parsing completely fails.
