Error Retry

Retry once after an unexpected critical exception so the agent has a chance to recover instead of failing immediately.

What It Does

This plugin hooks into the agent lifecycle and automatically retries the current loop once when an unhandled critical exception occurs.

It does not retry exceptions that are already treated as controlled agent flow, such as:

• HandledException
• RepairableException

Main Behavior

• Counter reset per monologue
  • Clears the retry counter at the start of a new monologue.
• Critical exception retry
  • On an unexpected exception, logs a warning, waits briefly, injects an agent-facing critical error message into history, and suppresses the original exception once.
• Single retry only
  • Uses an internal counter so the retry happens at most one time per monologue.
