Implements all Phase 1 recommendations from expert panel review: 1. **Response Analysis Pipeline** (Martin Fowler recommendation) - New lib/response_analyzer.sh component - Parses Claude Code output for completion signals - Detects test-only loops and stagnation - Updates .exit_signals file with structured data - Tracks confidence scores and progress indicators 2. **Circuit Breaker Pattern** (Michael Nygard recommendation) - New lib/circuit_breaker.sh component - Three-state pattern: CLOSED → HALF_OPEN → OPEN - Prevents runaway token consumption - Detects: no progress (3 loops), same errors (5 loops) - Automatic halt with clear user guidance - Manual reset capability 3. **Structured Output Contract** (Sam Newman recommendation) - Updated PROMPT.md template with RALPH_STATUS format - Defines clear JSON-parseable exit signals - SMART criteria for completion detection - Concrete examples for all scenarios 4. **Integration & Testing** - ralph_loop.sh integration of both components - 20 comprehensive BATS integration tests (all passing) - Tests cover: signal detection, circuit states, full loop flows - Validates Phase 1 implementation correctness **Impact**: Solves infinite loop problem, enables reliable exit detection, prevents token waste through systematic stagnation detection. **Test Results**: 20/20 integration tests passing 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
