Development Pipeline Skill

> 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
