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 --- .claude/settings.local.json | 6 +- SPECIFICATION_WORKSHOP.md | 453 +++++++++++++++++++++ USE_CASES.md | 523 +++++++++++++++++++++++++ lib/circuit_breaker.sh | 16 + templates/PROMPT.md | 159 ++++++++ tests/integration/test_edge_cases.bats | 413 +++++++++++++++++++ 6 files changed, 1569 insertions(+), 1 deletion(-) create mode 100644 SPECIFICATION_WORKSHOP.md create mode 100644 USE_CASES.md create mode 100644 tests/integration/test_edge_cases.bats diff --git a/.claude/settings.local.json b/.claude/settings.local.json index edf9bde..a18f027 100644 --- a/.claude/settings.local.json +++ b/.claude/settings.local.json @@ -7,7 +7,11 @@ "Bash(npx bats:*)", "Bash(npm init:*)", "Bash(grep:*)", - "Bash(git add:*)" + "Bash(git add:*)", + "Bash(git commit:*)", + "Bash(git push:*)", + "Bash(npm run test:integration:*)", + "Bash(test:*)" ], "deny": [], "ask": [] diff --git a/SPECIFICATION_WORKSHOP.md b/SPECIFICATION_WORKSHOP.md new file mode 100644 index 0000000..ecdbc97 --- /dev/null +++ b/SPECIFICATION_WORKSHOP.md @@ -0,0 +1,453 @@ +# Ralph Specification Workshop Guide + +**Based on**: Janet Gregory's "Three Amigos" collaborative testing approach +**Purpose**: Facilitate productive specification conversations for new Ralph features +**Audience**: Developers, Testers, Product Owners working on Ralph enhancements + +--- + +## What is a Specification Workshop? + +A specification workshop brings together three perspectives ("Three Amigos") to define features before implementation: + +1. **Developer** (How to implement) - Technical feasibility and approach +2. **Tester** (How to verify) - Edge cases, validation, quality criteria +3. **Product Owner / User** (What's the value) - Business requirements and success criteria + +**Goal**: Produce concrete, testable specifications that prevent bugs and misunderstandings. + +--- + +## Workshop Template + +### Feature: [Name] + +**Participants**: +- Developer: [Name] +- Tester: [Name] +- Product Owner: [Name] +**Date**: YYYY-MM-DD +**Duration**: 30-60 minutes + +--- + +## 1.

User Story + +**As a** Ralph user +**I want** automatic retries on temporary API errors +**So that** transient issues don't stop my development workflow + +### 2. Acceptance Criteria + +- [x] Ralph detects "rate_limit_error" in Claude output +- [x] Ralph waits appropriate time before retry (5 minutes) +- [x] Ralph limits retries to 3 attempts +- [x] Ralph falls back to user prompt on persistent failure +- [x] Retry attempts are logged clearly + +### 3. Questions from Tester + +**Q**: What counts as a "rate limit error" vs other errors? +**A**: Specific string "rate_limit_error" or "429" status code in output + +**Q**: Should retries count against hourly call limit? +**A**: Yes, retry attempts consume call quota + +**Q**: What if user Ctrl+C during wait period? +**A**: Graceful shutdown, save state, allow resume + +### 4. Implementation Approach + +**Approach**: +- Add retry logic to `execute_claude_code()` function +- Implement exponential backoff (5 min → 10 min → 15 min) +- Store retry state in `.retry_state` file +- Add retry counter to status.json + +**Constraints**: +- Must work with existing rate limit tracking +- Cannot bypass circuit breaker +- Retries must respect API 5-hour limit + +### 5.

Waiting 5 minutes..." +- Ralph sleeps for 300 seconds +- Ralph retries Claude Code execution +- If successful: continues normally, resets retry count to 0 + +**Scenario 2: Persistent Failure** + +**Given**: +- Ralph has retried 3 times already +- Each retry resulted in "rate_limit_error" + +**When**: 4th execution also returns rate limit error + +**Then**: +- Ralph logs "Retry limit exceeded (3 attempts)" +- Ralph prompts user: "Continue waiting? (y/n)" +- User decision determines next action (exit or continue) + +### 6. Edge Cases + +1. Rate limit error during first loop → Retry works immediately +2. User interrupts during wait → Clean shutdown, state preserved +3. Different error after retry → Handle as normal error, don't increment retry count +4.
