Implementation Details

1. Requirements Enhancement (PROMPT.md) ✅

Expert Recommendations: Karl Wiegers (SMART criteria), Gojko Adzic (Specification by Example) File Modified: templates/PROMPT.md Lines Added: +160

What Was Added:

📋 Exit Scenarios Section

Six concrete scenarios using Given/When/Then format:

Scenario 1: Successful Project Completion

• Given: All @fix_plan.md items marked [x], tests passing, no errors
• Then: OUTPUT EXIT_SIGNAL=true with COMPLETE status
• Ralph's Action: Gracefully exits loop with success message

Scenario 2: Test-Only Loop Detected

• Given: Last 3 loops only ran tests, no implementation
• Then: OUTPUT WORK_TYPE=TESTING with FILES_MODIFIED=0
• Ralph's Action: Increments test_only_loops, exits after threshold

Scenario 3: Stuck on Recurring Error

• Given: Same error in last 5 loops, no progress
• Then: OUTPUT STATUS=BLOCKED with error description
• Ralph's Action: Circuit breaker opens after 5 loops

Scenario 4: No Work Remaining

• Given: All tasks complete, nothing in specs/ to implement
• Then: OUTPUT EXIT_SIGNAL=true with COMPLETE status
• Ralph's Action: Immediate graceful exit

Scenario 5: Making Progress

• Given: Tasks remain, files being modified, tests passing
• Then: OUTPUT STATUS=IN_PROGRESS with progress metrics
• Ralph's Action: Continues loop, circuit stays CLOSED

Scenario 6: Blocked on External Dependency

• Given: Requires external API/library/human decision
• Then: OUTPUT STATUS=BLOCKED with specific blocker
• Ralph's Action: Logs blocker, may exit after multiple blocks

SMART Criteria Compliance:

• ✅ Specific: Each scenario has precise conditions
• ✅ Measurable: Boolean checks, countable metrics
• ✅ Achievable: Automated detection possible
• ✅ Relevant: Directly addresses exit detection
• ✅ Timely: Clear when conditions apply

Impact:

• Eliminates ambiguity in completion detection
• Provides Claude with concrete examples to follow
• Enables Ralph to parse and validate expected outputs

2. Use Case Documentation ✅

Expert Recommendation: Alistair Cockburn (Use Case methodology) File Created: USE_CASES.md (600 lines)

Contents:

Actor Catalog

• Ralph (Primary Actor): Autonomous agent orchestrating development loops
• Claude Code (Supporting Actor): AI development engine
• Human Developer (Supporting Actor): Initiator and reviewer

Six Primary Use Cases

UC-1: Execute Development Loop (Main workflow)

• Preconditions: PROMPT.md exists, @fix_plan.md has tasks
• Success: Task completed, files modified/committed, status tracked
• 14-step main scenario with extensions for:
  • Circuit breaker OPEN → halt with guidance
  • Rate limit exceeded → countdown wait
  • API 5-hour limit → user prompt
  • Execution failure → retry with backoff
  • EXIT_SIGNAL detected → graceful completion
  • Circuit breaker opens → stagnation halt

UC-2: Detect Project Completion (Response analysis)

• Success: Completion accurately determined, confidence scored
• 7-step main scenario with extensions for:
  • No structured output → natural language parsing
  • IN_PROGRESS status → work type analysis
  • BLOCKED status → intervention recommendation
  • High confidence → exit even without explicit signal

UC-3: Prevent Resource Waste (Circuit breaker)

• Success: Runaway loops halted, <1K tokens wasted
• 9-step main scenario with extensions for:
  • No files changed (1 loop) → monitor
  • No files changed (2 loops) → HALF_OPEN warning
  • No files changed (3 loops) → OPEN and halt
  • Same error (5 loops) → OPEN and halt
  • Files changed → recovery to CLOSED

UC-4: Handle API Rate Limits

• Success: Rate limits respected, execution continues
• 9-step main scenario with extensions for:
  • New hour → reset counter
  • Limit reached → countdown wait
  • API error → retry with user prompt

UC-5: Provide Loop Monitoring (ralph-monitor)

• Success: Real-time status visible, <2s latency
• 9-step continuous monitoring with extensions for:
  • No status.json → waiting message
  • Circuit OPEN → red alert display
  • Ralph exited → completion summary

UC-6: Reset Circuit Breaker (Manual intervention)

• Success: Circuit reset, Ralph can resume
• 11-step manual recovery with extensions for:
  • Cannot determine cause → status commands
  • PROMPT.md issue → edit and clarify
  • Environment issue → fix configuration

3. Enhanced Test Coverage ✅

Expert Recommendations: Lisa Crispin (Testing Strategy), Janet Gregory (Quality Conversations) File Created: tests/integration/test_edge_cases.bats (330 lines)

20 New Edge Case Tests:

Boundary Conditions:

1. ✅ Empty output file (0 bytes)
2. ✅ Very large output file (100KB+)
3. ✅ Output length exactly at 50% decline threshold
4. ✅ Very high loop numbers (loop 9999)
5. ✅ Negative file count (treat as 0)

Error Conditions: 6. ✅ Malformed RALPH_STATUS block 7. ✅ Corrupted circuit breaker state file (JSON recovery) 8. ✅ Corrupted circuit breaker history file 9. ✅ Missing git repository (graceful fallback) 10. ✅ Missing exit signals file (auto-create)

Data Handling: 11. ✅ Unicode characters in output (emoji support) 12. ✅ Binary-like content with control characters 13. ✅ Multiple RALPH_STATUS blocks (malformed) 14. ✅ Status block with unknown/extra fields

Complex Scenarios: 15. ✅ Simultaneous test-only and completion signals (precedence) 16. ✅ Conflicting signals handled appropriately 17. ✅ Circuit breaker rapid state transitions 18. ✅ Rapid loops in same second (timestamp handling) 19. ✅ Exit signals array overflow (rolling window) 20. ✅ Stuck loop with varying error messages

Test Results: 20/20 passing (100%) Combined Total: 40 integration tests (20 core + 20 edge cases)

Code Quality Improvement:

• Enhanced init_circuit_breaker() with JSON validation
• Auto-recovery from corrupted state files
• Graceful handling of missing dependencies
