Phase Ordering Skill
CRITICAL: Always reference this skill when creating phases. Incorrect ordering causes failures.

Dependency Rules
Hard Dependencies (MUST follow)
| Phase | MUST Come After |
|---|---|
| Database | Setup |
| Auth | Database |
| API | Infrastructure, Auth |
| Business Logic | Database, API contracts |
| Frontend | API contracts exist |
| Features | Business logic, Frontend foundation |
| Integration Tests | Feature implementation |
| Security | Implementation complete |
| Documentation | Features stable |
| Deployment | Tests pass, Security done |
Soft Dependencies (Recommended)
| Phase | Should Come After |
|---|---|
| Performance tests | Integration tests |
| Security hardening | Basic tests exist |
| Documentation | Most features done |
What Can Run in Parallel
Safe Parallel Work
After Phase 005 (API Layer):
├── Backend features (Phase 006+)
└── Frontend development (Phase 007+)
After Phase 008 (Features):
├── Integration tests
├── Security audit
└── Documentation
Never Parallel
❌ Database schema + API (needs schema)
❌ Auth + features (needs auth)
❌ Frontend + backend for SAME feature
❌ Tests + implementation of same feature
Task Ordering Within Phase
Standard Task Order
1. Schema/Config changes
2. Types/Interfaces
3. Core implementation
4. Integration (routes, wiring)
5. Tests
6. Exports/Index files
Example: API Endpoint Phase
Task 1: Add database migration
Task 2: Create entity/model
Task 3: Create repository
Task 4: Create service/use case
Task 5: Create route handler
Task 6: Add validation schemas
Task 7: Register routes
Task 8: Write unit tests
Task 9: Write integration tests
Phase Dependencies Lookup Table
Phase 001 (Setup) → []
Phase 002 (Database) → [001]
Phase 003 (Infrastructure)→ [001, 002]
Phase 004 (Auth) → [002, 003]
Phase 005 (API) → [003, 004]
Phase 006 (Business) → [002, 005]
Phase 007 (Frontend) → [001, 005]
Phase 008 (Features) → [006, 007]
Phase 009 (Testing) → [008]
Phase 010 (Security) → [008, 009]
Phase 011 (Docs) → [008]
Phase 012 (DevOps) → [009, 010]
Phase 013 (Polish) → [all]
Quick Validation
Before creating phases, verify:
- No phase depends on a later phase
- Database phases come before API phases
- Auth exists before protected features
- API contracts exist before frontend
- Implementation before testing
- All dependencies can be satisfied
Anti-Patterns
❌ WRONG
Phase 1: Build login UI
Phase 2: Create user table
Phase 3: Add auth endpoints
✅ CORRECT
Phase 1: Create user table + migrations
Phase 2: Add auth endpoints
Phase 3: Build login UI
