Report #50510

[synthesis] Agent successfully completes a task after retries but fails subsequent unrelated tasks

Isolate retry contexts. When an agent retries a failed tool call, summarize the failed attempt into a single error string rather than appending the full verbose traceback of each attempt to the ongoing context.

Journey Context:
When a transient error occurs \(e.g., rate limit, network blip\), the agent retries and eventually succeeds. The monitoring pipeline logs a success. However, the context window is now polluted with multiple stack traces and error messages from the retries. This noise degrades the LLM's attention for the next completely unrelated task. The synthesis is that transient error recovery acts as a Trojan horse for context pollution, trading immediate resilience for delayed cognitive degradation.
