Codex API scaffolder — REST endpoint from a plain-English spec
Describe your endpoint in plain English and Codex builds the full implementation: route handler, request validation, error responses, and a usage example — no boilerplate writing required.
Paste into the Codex CLI or as a task in Cursor: 'Generate a complete, production-ready [LANGUAGE, e.g. TypeScript / Python] REST API endpoint with the following spec: Endpoint: [METHOD] [PATH, e.g. POST /api/users/invite] Purpose: [ONE SENTENCE — what this route does] Request body: [DESCRIBE FIELDS, types, and which are required] Auth: [Bearer token / API key / none — and what it should check] Success response: [HTTP status + shape of the response JSON] Error cases to handle: [e.g. duplicate email 409, invalid input 422, unauthorized 401] Generate: 1. The route handler with input validation (use [zod / pydantic / joi] for schema enforcement) 2. Typed request/response interfaces 3. Inline error handling — no try/catch around the whole function; handle each error case explicitly 4. A brief JSDoc/docstring comment on the handler function 5. A cURL example showing a valid request and the expected 200 response Style rules: [framework, e.g. Express / Fastify / Flask / Next.js API routes]. No placeholder comments. No TODO. The output must run without modification.' Tip: paste your existing route file first and say 'following the patterns in this file, add:' — Codex will match your naming conventions, error format, and middleware usage exactly rather than introducing a new style.
