Complete knowledge of the 9-phase development pipeline
When to Use
- When user says "I have little development experience"
- When using
/pipeline-*commands - When asked "How do I start development?", "What's the order?"
- When starting a new project from scratch
Optional Application Principle
This skill is optional, not mandatory.
Activation conditions:
- When non-developers/beginner developers start development
- When user explicitly requests guidance
- When /pipeline-start command is used
Deactivation conditions:
- When experienced developers want to "proceed freely"
- For non-development AI work (documentation, analysis, etc.)
- For existing project maintenance/bug fixes
## 9-Phase Pipeline Overview
Phase 1: Schema/Terminology ──→ Define data structures and domain terms Phase 2: Coding Convention ────→ Define code writing rules Phase 3: Mockup Development ───→ Feature validation with HTML/CSS/JS + JSON Phase 4: API Design/Impl ──────→ Backend API + Zero Script QA Phase 5: Design System ────────→ Build component system Phase 6: UI Implementation ────→ Actual UI implementation and API integration Phase 7: SEO/Security ─────────→ Search optimization and security hardening Phase 8: Review ───────────────→ Architecture/convention quality verification Phase 9: Deployment ───────────→ Production deployment
## Relationship with PDCA (Key Concept)
❌ Wrong understanding: Mapping entire Pipeline to PDCA ❌ (Plan=Phase1-3, Do=Phase4-6, Check=Phase7-8, Act=Phase9)
✅ Correct understanding: Run PDCA cycle within each Phase
Phase N ├── Plan: Plan what to do in this Phase ├── Design: Detailed design ├── Do: Execute/implement ├── Check: Verify/review └── Act: Confirm and move to next Phase
## Phase Application by Level
| Phase | Starter | Dynamic | Enterprise |
|-------|---------|---------|------------|
| 1. Schema/Terms | Simple | Detailed | Detailed |
| 2. Convention | Basic | Extended | Extended |
| 3. Mockup | O | O | O |
| 4. API | - | bkend.ai | Direct impl |
| 5. Design System | Optional | O | O |
| 6. UI + API | Static UI | Integration | Integration |
| 7. SEO/Security | SEO only | O | O |
| 8. Review | - | O | O |
| 9. Deployment | Static hosting | Vercel etc. | K8s |
### Starter Level Flow
Phase 1 → 2 → 3 → 5(optional) → 6(static) → 7(SEO) → 9
### Dynamic Level Flow
Phase 1 → 2 → 3 → 4(bkend.ai) → 5 → 6 → 7 → 8 → 9
### Enterprise Level Flow
Phase 1 → 2 → 3 → 4(direct impl) → 5 → 6 → 7 → 8 → 9
