  • get_stuck_report

    Get a detailed analysis of why an agent is stuck, including action history, patterns, token waste estimate, and recovery recommendations.

    Log an agent action for loop detection. Maintains a rolling window of the last 50 actions and returns early warnings.

  • register_agent
