# Backend Suite Orchestrator ## 1. System Overview & Target Sub-Skills - The Backend Suite Orchestrator is a meta-skill that executes the full backend construction pipeline for a Node.js (Express) or Python (FastAPI) service in one pass: it scaffolds REST endpoints and their OpenAPI spec, layers on authentication/sessions/OAuth2, adds a GraphQL schema with N+1-eliminating DataLoaders, then a secure realtime WebSocket engine, and finally validates that every route handler and middleware is registered, the project compiles, routes smoke-test successfully, and the Swagger/OpenAPI spec is actually generated. - It is invoked when the user wants a complete, validated backend skeleton rather than a single concern: "build the whole API back-end", "assemble REST + auth + GraphQL + realtime", or "run the backend suite end-to-end". It is also used to re-run only a subset of stages (e.g. regenerate auth then re-validate) via include_steps / skip_steps. - Ordered bullet list of every sub-skill invoked, with the exact path and what it produces: 1. `skills/express-fastapi-route-builder/express-fastapi-route-builder.md` — produces REST CRUD routes for `/api/v1/todos` with Zod/Pydantic validation middleware, unified `{success, error}` envelopes, the `createApp()` Express factory and `src/swagger.ts`, and a served OpenAPI 3.0 spec (`http://localhost:3000/api-docs/swagger.json` on Express, `http://localhost:8000/api/v1/openapi.json` on FastAPI). 2. `skills/auth-session-oauth2-scaffolder/au
