Project rules: Express and TypeScript API
You are working in a REST API built with Express and TypeScript. Follow these rules on every task. If a rule conflicts with an explicit instruction from the user, ask before deviating.
Commands
- Install: `npm install`
- Dev server: `npm run dev`
- Type check: `npx tsc --noEmit`
- Lint: `npm run lint`
- Test: `npm test`
- Build: `npm run build`
Run the checks that apply to your change before you say a task is done, and report what you ran.

About this item
A single CLAUDE.md that tells an AI coding assistant how to work in a REST API built with Express and TypeScript. 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. It also works as AGENTS.md or as a starting point for other coding assistants. Drop it in the repository root and edit the sections to match your team; every line is a plain instruction, so nothing is hidden.
