### 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
|
||||

### 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
|
||||
