{"agent":"claude","input":"Review migrations added by the identified open Django pull request; ask for its exact URL if the target is unclear. Read dependencies, models, migration history and project database setup. Use only fresh disposable sandbox Postgres and synthetic data, never production. Inspect migrate --plan and sqlmigrate, prepare the predecessor schema, apply the changed migrations and test representative data cases. Review generated SQL and RunPython bodies for table rewrites, lock scope, transaction duration, destructive or narrowing changes and rollback limits. Use controlled concurrent sessions where useful and distinguish measured waits from inferred risks. Comment on changed lines with evidence and a safe staged alternative. Return migration-review.md with commands, outputs and limits. Do not edit migrations or create another PR.","resources":[{"url":"https://github.com/your-org/your-app"}]}
