{"agent":"claude","input":"Containerize this NestJS app. First read package.json, the lockfile, nest-cli.json, tsconfig.json, tsconfig.build.json and src/main.ts, and list the Node version the repository implies, the package manager, the build command and its output directory, the entry file, the port, and every environment variable or service the app needs at runtime. Write a production multi-stage Dockerfile: a dependencies stage that installs from the lockfile, a build stage that runs the Nest build and prunes dev dependencies, and a slim runtime stage with only the compiled output and production dependencies, running as a non-root user with NODE_ENV and PORT set. Add a .dockerignore and a compose.yaml with the app service, its port and a health check, plus any database or queue the app depends on. Build the image in the sandbox, start it with docker compose, request the root route and fix anything until it answers. Open a pull request with the image size, the container log, and the commands to build and run it locally.","resources":[{"url":"https://github.com/your-org/your-app"}]}
