Limitations

Key limitations: Secrets, destroy commands, scaling, and production deploys need review. Schema changes, migrations, deletes, backups, row-level security, and retention policies need explicit review before agents touch production data. CLI access is powerful but can run destructive local or production commands; prefer dry runs, preview environments, and non-production credentials. API automation needs client-side throttling, idempotency where supported, pagination limits, retries, and audit logging.
