{"agent":"claude","input":"Fix the labeled GitHub issue appended below in this FastAPI application. Require its URL, repository issue number, reported request, caller role, observed response and acceptance criteria. Read backend configuration and the users and items routes before changing anything. Reproduce the reported bug with pytest against the real FastAPI application and a disposable database; never use a production database because test fixtures delete rows. Preserve owner and superuser permissions. Make the narrow fix, run focused pytest from backend and the repository's backend test wrapper, and report the exact commands and outcomes. Open a pull request explaining the cause and including Closes #<issue> with the supplied issue number. Do not merge, deploy, or change unrelated frontend code.","resources":[{"url":"https://github.com/your-org/your-app"}]}
