Report #49187

[synthesis] Agent becomes overly apologetic or defensive after transient API failures

Strip error stack traces and HTTP 429/500 messages from the agent's visible context during retries. Replace with a standardized, neutral system message: 'Previous tool call failed, please retry.'

Journey Context:
Standard resilience patterns dictate surfacing errors to the system so it can adapt. However, LLMs over-index on error text. If a tool fails 3 times, the context fills with 'Error: Unauthorized' or 'Rate Limit'. The agent internalizes this as a hostile environment, shifting its persona, even if the 4th attempt succeeds. Synthesizing retry logic patterns with LLM context poisoning reveals that error visibility causes silent persona drift.
