{"agent":"claude","input":"Review the Astro pull request whose URL, base SHA and head SHA the caller appends below. Require the PR identity before proceeding; the repository resource is the caller's application, not the public example. Check out the supplied PR head and verify the revision. Read package.json, the checked-in lockfile, workspace and Vitest configuration. Use the declared package manager; for a Starlight-style pnpm workspace run pnpm install --frozen-lockfile and pnpm --filter @astrojs/starlight test --run. Inspect sidebar navigation and i18n changes with their surrounding implementation, configuration and tests. Post one GitHub review with concrete failure scenarios and current-head file-and-line citations, separating blocking defects from suggestions and including exact test outcomes and setup limitations. If posting is unavailable, return the review and say it was not posted. Do not push commits, approve without evidence or merge.","resources":[{"url":"https://github.com/your-org/your-app"}]}
