Phase 2: Requirements, testing, and documentation enhancements
Implements all Phase 2 high-priority recommendations from expert panel: **1. Requirements Improvement** (Karl Wiegers, Gojko Adzic) - Enhanced templates/PROMPT.md with 6 concrete Given/When/Then scenarios - Specification by Example format for all exit conditions - Clear expectations for each scenario type: * Successful completion * Test-only loops * Stuck on errors * No work remaining * Making progress * Blocked on dependencies **2. Use Case Documentation** (Alistair Cockburn) - Created comprehensive USE_CASES.md (600+ lines) - Defined 6 primary use cases with full Cockburn format: * UC-1: Execute Development Loop * UC-2: Detect Project Completion * UC-3: Prevent Resource Waste * UC-4: Handle API Rate Limits * UC-5: Provide Loop Monitoring * UC-6: Reset Circuit Breaker - Includes actors, goals, success scenarios, extensions, edge cases - Clear goal hierarchy and success metrics **3. Enhanced Test Coverage** (Lisa Crispin, Janet Gregory) - Added tests/integration/test_edge_cases.bats (20 new tests) - Edge cases: empty files, large files, corrupted JSON, unicode - Boundary conditions: exact thresholds, overflow scenarios - Error conditions: missing git, malformed data, rapid transitions - All 40 integration tests passing (100% success rate) **4. Circuit Breaker Robustness** - Enhanced init_circuit_breaker() with corruption detection - Auto-recovery from corrupted state/history files - Validates JSON before use, recreates if invalid **5. Specification Workshop Guide** - Created SPECIFICATION_WORKSHOP.md - Three Amigos methodology with templates - Includes complete example workshop - Best practices and red flags - Quick 15-minute template for small features **Test Results**: 40/40 integration tests passing **Documentation Added**: 1,200+ lines (USE_CASES.md, SPECIFICATION_WORKSHOP.md) **Coverage Improvement**: Edge cases and error conditions fully tested 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
