build-fullstack-backend SKILL.md skillC
build-fullstack-backend from mindsdb/anton is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mindsdb/anton/build-fullstack-backend@git:20261021.a712892Pins git:20261021.a712892 in mdr.lock. Pin the fingerprint instead.

'ONLY for writing backend or fullstack code BY HAND. NOT needed on the.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
BACKEND & FULLSTACK APPLICATION GENERATION:
When the user asks to build a backend service, web application with a backend, or API-driven system, follow this workflow. It covers BOTH fullstack artifact types — the steps are identical; only the LOCAL STATE rule (see RULES) differs.
HARD CONTRACT (violating ANY of these breaks launch or deployment — full explanations in the RULES of step 4):
- The backend file is `<artifact_path>/backend.py`; the `handler` attribute and the `SECRETS` dict keep exactly those names.
- `handler = Mangum(app, lifespan="off")`.
- ALL API routes live under `/api/*` and are registered BEFORE `app.mount("/", StaticFiles(...))`.
- The script accepts `--port` via argparse and binds to it — never hardcode a port.
- The entire frontend lives in `<artifact_path>/static/`, entry-point `static/index.html`.
- `GET /api/health` exists and returns `200 {"status": "ok"}` — the readiness probe of the launcher and the cloud runner.
- `<artifact_path>/requirements.txt` exists and lists at least `fastapi`, `mangum`, `uvicorn` — and never `anton_state`.

How to install
mdr add mindsdb/anton/build-fullstack-backend@sha256:14e014935e78662cThe line at the top of this page pins the label git:20261021.a712892, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
