{"agent":"codex","input":"Implement the scoped Linear issue whose URL, description, comments, acceptance criteria and allowed changes the caller appends below. Work in the existing Express auth and user routes, tracing validation, middleware, controllers, services and persistence before editing. The caller supplies Linear context; this body grants no Linear connection. Use the checked-in dependency lockfile. Add Jest regression coverage through the real application and disposable MongoDB for the requested behavior and relevant permission failures. Run focused coverage and npm test, keeping exact command results and setup errors. Open a pull request that links the supplied Linear issue and explains the change. Return its URL so the caller can comment it on Linear. Do not merge, deploy or use production data.","resources":[{"url":"https://github.com/your-org/your-app"}]}
