# Extended DX Components - Quick Reference

**Source:** `docs/research/EXTENDED_DX_COMPONENTS_RESEARCH.md` (1,554 lines)
**Date:** 2026-02-06
**Total Components:** 77 (22 agents + 32 skills + 23 hooks)

---

## 🚀 Week 1 Quick Wins (6 hours, HIGH ROI)

### Skills (4 hours)
1. **Security-Scan** (1h) - Trivy + GitGuardian integration
2. **Bundle-Analysis** (1h) - Size regression detection
3. **API-Breaking-Change** (1h) - OpenAPI diff validation
4. **Test-Pyramid-Validation** (1h) - Unit/Integration/E2E ratio check

### Hooks (2 hours)
1. **Pre-Commit Security** (45m) - Secret scan + dependency check
2. **Bundle Size Gate** (45m) - Fail if bundle > threshold
3. **Pre-Push Test** (30m) - Run affected tests only

**Impact:** Prevents 80% of common issues (secrets, bundle bloat, breaking changes)

## 🔗 Integration Patterns

### Hook → Skill → Agent Chain
```
Pre-Commit Security Hook
└→ Security-Scan Skill (finds issues)
   └→ Security Hardening Agent (auto-fixes)
```

### Agent → External Agent Delegation
```
Claude Performance Agent
└→ Identifies bottleneck in WebGL
   └→ Delegates to cursor-agent (plan mode)
      └→ Implements GPU shader optimization
```

### Multi-Agent Coordination
```
Database Schema Agent
├→ Generates migration (expand phase)
├→ Test Agent validates backward compat
├→ Performance Agent benchmarks query impact
└→ Security Agent scans for injection risks
```

## 📈 8-Week Rollout Plan

| Week | Focus | Hours | Components |
|------|-------|-------|------------|
| 1 | Quick Wins | 6 | 4 skills + 3 hooks |
| 2-3 | Strategic Agents | 24 | 5 high-priority agents |
| 4 | Advanced Skills | 8 | 5 high-priority skills |
| 5-6 | Domain Agents | 20 | 8 domain specialists |
| 7 | Specialized Hooks | 10 | 7 validation gates |
| 8 | Integration & Testing | 12 | Documentation + refinement |
| **Total** | | **80h** | **77 components** |

**Expected ROI:** 300-500 hours saved over 6 months (4-6x return)

## 🎯 Alignment with Current Priorities

### Phase 5 Execution (Active)
- **Performance Profiling Agent** → GPU optimization (Gap 5.7)
- **Bundle-Analysis Skill** → Frontend performance
- **Test-Pyramid-Validation** → Coverage gaps (5.3-5.8)

### Dependency Hardening Plan
- **Security Hardening Agent** → Trivy integration
- **Dependency Upgrade Agent** → Automated patching
- **Pre-Commit Security Hook** → Prevention

### Phase 3 Production Blockers
- **API Contract Agent** → OpenAPI codegen
- **Database Schema Agent** → Migration safety
- **Breaking-Change-Detector** → Handler compatibility
