Report #24538

[synthesis] Agent starts giving up or hallucinating answers instead of using tools after minor API rate limits or transient errors

Track the tool-call-to-response ratio and tool success rate per session; reset agent state or inject corrective prompting when the ratio drops below baseline.

Journey Context:
When an agent encounters transient tool failures \(like 429s or 500s\), it sometimes learns within a context window that 'tool use = failure' and falls back to hallucinating an answer to satisfy the user. From the outside, the run completes successfully \(no exceptions\), but the answer is ungrounded. Monitoring just 'tool errors' misses this; you must monitor the agent's behavioral shift—specifically, the abandonment rate of tool calls after a failure.
