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

# FastAPI Best Practices for AI Agents

A machine-readable companion to [README.md](./README.md) for AI coding agents
working in FastAPI projects. Same rules, restructured for fast pattern matching:
version pins, Do/Don't blocks, anti-patterns, and a quick-reference table.

## Compatibility Matrix

Pin to these versions or newer. Examples in this file assume them.

| Dependency       | Minimum   | Notes                                                |
|------------------|-----------|------------------------------------------------------|
| Python           | 3.11      | Required for `StrEnum` and `X \| Y` union syntax     |
| FastAPI          | 0.115     | `Annotated[T, Depends(...)]` is the idiomatic form   |
| Pydantic         | 2.7       | v1 APIs (`json_encoders`, `.dict()`) are removed     |
| pydantic-settings| 2.4       | Lives in a separate package since Pydantic v2        |
| SQLAlchemy       | 2.0       | Use the async API (`AsyncSession`, `async_sessionmaker`) |
| Alembic          | 1.13      | Async-aware migrations                               |
| httpx            | 0.27      | Use `ASGITransport` for in-process tests             |

How to install

The exact contents, by fingerprint
mdr add yzfly/skills/skills/cto/references/payload/backend/python-fastapi/AGENTS.md@sha256:b6f366ac4c0c318e

The line at the top of this page pins the label git:20260503.c091e90, 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.
