+# Engineering Skills — Codex CLI Instructions
+
+When working on engineering tasks, use the engineering skill system:
+
+## Routing
+
+1. **Identify the domain:** Architecture, frontend, backend, DevOps, security, AI/ML, data, or QA
+2. **Read the specialist SKILL.md** for detailed instructions
+3. **Use Python tools** for scaffolding and analysis
+
+## Python Tools
+
+All scripts in `engineering-team/*/scripts/` are stdlib-only and CLI-first. Run them directly:
+
+```bash
+python3 engineering-team/senior-fullstack/scripts/project_scaffolder.py --help
+python3 engineering-team/senior-security/scripts/threat_modeler.py --help
+python3 engineering-team/senior-frontend/scripts/bundle_analyzer.py --help
+```
+
