Limitations

Key limitations: File access rules, malware scanning needs, and deletion policies need product review. Schema changes, migrations, deletes, backups, row-level security, and retention policies need explicit review before agents touch production data. API automation needs client-side throttling, idempotency where supported, pagination limits, retries, and audit logging. Store credentials outside source control and use least-privilege scopes, short-lived tokens, or restricted keys where the product supports them.
