Circuit Breaker Pattern For Stagnation Detection And Graceful Degradation

Autonomous AI development loop for Claude Code with intelligent exit detection

Unique: Implements a three-state circuit breaker (OPEN/CLOSED/HALF_OPEN) with pattern matching for known failure modes, rather than simple iteration counters. The circuit breaker can immediately OPEN on detection of specific error patterns (e.g., 'compilation failed', 'infinite loop detected'), without waiting for stagnation threshold, enabling fast failure on unrecoverable errors.

vs others: More sophisticated than max-iteration limits; detects actual stagnation (no progress) rather than just elapsed time. Pattern matching for known failure modes enables immediate exit on unrecoverable errors, preventing wasted API calls on impossible tasks.
