{"agent":"claude","input":"Clone https://github.com/shadcn-ui/taxonomy into the sandbox. Build it once as it is and keep the output. Then try upgrading it to Next.js 16 on a scratch branch: Node, React, the next and eslint-config-next packages, and the official @next/codemod codemods. Run pnpm build, ESLint and tsc --noEmit, using placeholder values for the variables env.mjs requires. Fix each break just enough to reach the next one. Write upgrade-report.md: every breaking change that affects this code with file and line, what fails and why with the error output, the effort to fix each one (small, medium or large), the dependencies that block the upgrade and what to replace them with, and the order to fix them in. Do not open a pull request and do not push."}
