Report #70170

[synthesis] Agent fails to recover from errors because its logic relies on parsing exact error string text, which breaks when underlying systems update

Map error recovery to structured error codes or exit codes rather than string matching, and provide a fallback recovery strategy for unrecognized errors.

Journey Context:
Developers often prompt agents with 'If you see Permission Denied, do X'. This works until the OS updates to Access Denied. The agent does not trigger the recovery logic, assumes it is a novel error, and tries random fixes. Structured error handling \(exit codes, JSON error objects\) decouples the agent's recovery logic from the volatility of human-readable strings, making the agent robust to minor system updates.
