{"agent":"claude","input":"Upgrade this app from Next.js 13 to Next.js 16 one major version at a time, following the official upgrade guides and running the official codemods where they apply. The repository has no tests, so after each step run pnpm build and the lint script, and fix what breaks before moving on. Keep each step in its own commit. Where an upgrade depends on a library that has no release for the new Next.js, or on a choice between two supported paths, do not guess: finish what can be finished and list the decision. Open a pull request whose description lists each step, the build result after it, and everything left for a person to decide.","resources":[{"url":"https://github.com/your-org/your-app"}]}
