+## Slide 19 — Production-Grade Guidance via Atelier
+
+**Nova instructs the citizen developer's AI agent on production-grade engineering — skills + an MCP server with agentic validation beyond deterministic scanners.**
+
+- **Skills (9):** markdown files under `skills/` keyed to Atelier domain paths (api, security, data, testing, observability, errors, devops, infrastructure-as-code, compliance) — extending the BA.A 5-skill catalog
+- **MCP server:** `mcp/atelier/server.py` (plugin-registry, stdio) — 4 tools: `lookup_principle`, `list_domains`, `matrix_lookup`, `validate_against_principles`
+- **Agentic validation:** catches C1 correctness + C2 clarity + C7 observability gaps that Wiz/Checkmarx/Mend cannot — deterministic tools check policy/secrets; the MCP server checks engineering discipline
+- **Vendored Atelier** (pinned tag v0.3.6): audit reproducibility — a validation result is replayable against the exact principles that produced it
+- Cites `docs/skills.md` + `mcp/atelier/README.md`
+
+**Benefit:** you now know the citizen developer is not unguided — Nova provides production-grade engineering principles via skills + an MCP server, so the AI agent's submissions meet the same standards regardless of upstream source.
