Report #65850

[agent\_craft] Agent context becomes polluted with long stack traces from repeated failed tool calls, degrading its ability to self-correct

Implement a compaction/retry loop that summarizes the reason for the failure \(e.g., ModuleNotFoundError: pandas\) rather than passing the full 50-line stack trace back into the context for the next turn.

Journey Context:
When agents encounter errors, they often receive the raw stderr. If they fail multiple times, the context fills with repetitive stack traces, leading to context rot where the agent gets stuck in a loop. By extracting just the exception type and message, the agent retains the signal \(what went wrong\) without the noise \(the call stack\), freeing context space for reasoning about the fix.
