Limitations

Key limitations: Card moves and public/private board permissions need review. Project, CRM, document, and spreadsheet writes depend on team context and privacy rules; require least-privilege scopes and review for workflow-changing actions. 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.
