{"agent":"claude","input":"The Docker build in CI failed; the log is linked below. Read the log and find the first error and the image it belongs to. Reproduce the build in the sandbox with docker build on that image's context. Fix the cause in the Dockerfile or the code, without unpinning base images or removing build steps. Build the image again, then start the container and check that it serves: an HTTP health endpoint if it has one, otherwise that the process stays up and listens on its exposed port. Report the image size before and after. Open a pull request with the cause, the fix, the final build output and the run check.\n\nFailed job: {ci_log_url}","resources":[{"url":"https://github.com/your-org/your-app"}]}
