WHAT IT DOES

What duplicate_card does on Framedeck

AI agents use duplicate_card to create or update resources in Framedeck — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Framedeck environment.

WHY IT NEEDS A POLICY

Why duplicate_card needs a policy

This tool creates a new card (reversible write operation) by duplicating an existing one. It does not execute code, delete data irreversibly, move money, or have destructive effects. The operation is typical of content management systems and can be undone by deleting the duplicate. The blast radius is minimal—worst case, duplicate cards clutter a board but cause no data loss or external side effects.

From the tool's definition Tool name 'duplicate_card' and description 'Duplicate a card including its checklist items' indicate creation of new content by copying existing data.
