# Engineering Advanced Skills — Codex CLI Instructions

When working on advanced engineering tasks, use the POWERFUL-tier skill system:

## Routing

1. **Identify the domain:** Architecture, CI/CD, databases, observability, agents, RAG, or security
2. **Read the specialist SKILL.md** for detailed instructions

## Key Skills by Task

| Task | Skill |
|------|-------|
| Agent architecture | agent-designer |
| RAG systems | rag-architect |
| MCP servers | mcp-server-builder |
| CI/CD pipelines | ci-cd-pipeline-builder |
| Database schema | database-designer |
| Performance tuning | performance-profiler |
| API review | api-design-reviewer |
| Monitoring/SLOs | observability-designer |
| Release management | release-manager |
| Security audit | skill-security-auditor |
| Tech debt | tech-debt-tracker |

## Rules

- Load only 1-2 skills per request — don't bulk-load
- These are advanced skills — combine with engineering-team/ core skills as needed
