{"agent":"codex","input":"Upgrade Gatsby and its plugins to the latest compatible versions with npm. Upgrade gatsby and every gatsby-* package together so their peer ranges match, then the remaining dependencies. Keep React on its current major unless the new Gatsby supports a newer one. This project has no test suite, so run npm run build, then gatsby serve, and check that the home page, every post, /rss.xml and the manifest load and that the feed lists every post. Leave out any upgrade that breaks the build or those checks and say why with the error. Finish with npm run clean, npm ci and npm run build. Open a pull request with one line per bump.","resources":[{"url":"https://github.com/your-org/your-app"}]}
