Build production-grade FastAPI backends with SQLModel, Pydantic, and JWT authentication. Use this skill when building REST APIs, integrating with Neon PostgreSQL, implementing Better Auth JWT verification, or creating CRUD endpoints. Includes patterns for audit logging, worker/agent parity, and OpenAPI documentation.
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 Backend
Build production-grade FastAPI backends with SQLModel, Pydantic v2, and JWT/JWKS authentication patterns.
## When to Use
- Building REST API endpoints with FastAPI
- Creating SQLModel schemas for Neon PostgreSQL
- Implementing JWT verification against Better Auth JWKS
- Designing OpenAPI contracts for frontend consumption
- Adding audit logging to API operations
- Ensuring human-agent parity in API design
## Quick Start
```bash
# Project setup
uv init backend && cd backend
uv add fastapi sqlmodel pydantic httpx python-jose uvicorn
# Development
uv run uvicorn main:app --reload --port 8000
# Access docs
open http://localhost:8000/docs # Swagger UI with Authorize button
```
## Core Patterns
### 1. SQLModel Schema (Database + API)
SQLModel combines SQLAlchemy and Pydantic. Use `table=True` for database models:
```python
from sqlmodel import SQLModel, Field
from datetime import datetime
from typing import Optional, Literal
# Base model (shared fields, no table)
class TaskBase(SQLModel):
title: str = Field(max_length=200)
description: Optional[str] = None
status: Literal["pending", "in_progress", "review", "completed", "blocked"] = "pending"
…Read the whole file at its exact version.
How to install
mdr add mjunaidca/mjs-agent-skills/fastapi-backend@sha256:4f496508f4f0d335The line at the top of this page pins the label git:20251221.f6c90d7, 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.
