## 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
|
||
|
||
#### Goal Hierarchy
|
||
```
|
||
SYSTEM GOAL: Complete project with minimal token waste
|
||
├─ Execute loops (UC-1)
|
||
├─ Detect completion (UC-2)
|
||
├─ Prevent waste (UC-3)
|
||
├─ Respect limits (UC-4)
|
||
└─ Provide visibility (UC-5)
|
||
```
|
||
|
||
#### Success Metrics
|
||
| Use Case | Criteria | Target |
|
||
|----------|----------|--------|
|
||
| UC-1 | Completion rate | >95% |
|
||
| UC-2 | Detection accuracy | >90% |
|
||
| UC-3 | Circuit trip time | <3 loops |
|
||
| UC-4 | Rate compliance | 100% |
|
||

|
||
|
||
**Impact**:

**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
|
||

|
||
|
||
#### Best Practices
|
||
**Before Workshop**:
|
||
- Prepare user story 24 hours ahead
|
||
- Provide relevant context
|
||
- Time-box to 30-60 minutes
|
||
|
||
**During Workshop**:
|
||
- Focus on one feature at a time
|
||
- Use concrete examples, not abstractions
|
||
- Encourage "what could go wrong?" questions
|
||
- Document decisions in real-time
|
||
|
||
**After Workshop**:
|
||

|
||
- Create tracked action items
|
||
- Use scenarios for test cases
|
||
|
||
#### Red Flags
|
||
- ❌ "We'll figure it out during implementation"
|
||
- ❌ "That's edge case, handle later"
|
||
- ❌ Vague acceptance criteria
|
||
- ❌ No concrete examples
|
||
|
||
#### Success Indicators
|
||
- ✅ Clear, testable scenarios
|
||
- ✅ Edge cases identified before coding
|
||
- ✅ All three perspectives represented
|
||
- ✅ Concrete examples throughout
|
||
|
||
#### Quick Template (15 minutes)
|
||
Condensed format for small features:
|
||
- User story
|
||
- Key scenarios (2-3)
|
||
- Edge cases
|
||
- Test checklist
|
||
- Done criteria
|
||
|
||
**Impact**:
|
||
- Prevents bugs through upfront specification
|
||
- Ensures quality conversations happen early
|
||
- Provides repeatable process for future features
|
