About this item
A single .cursorrules that tells an AI coding assistant how to work in a FastAPI service written in Python with type hints. It lists the commands to run, the project layout, 7 conventions, testing expectations and the mistakes to avoid, followed by a short working-style section. Rename it to CLAUDE.md or AGENTS.md if your assistant expects that file. Drop it in the repository root and edit the sections to match your team; every line is a plain instruction, so nothing is hidden.
