## Why create_card is rated Medium

This tool creates new data (a Trello card) reversibly—cards can be modified, archived, or deleted later. It does not execute arbitrary operations, delete data irreversibly, or move money. The medium severity reflects that misuse could clutter boards or create unwanted tasks, but the impact is limited to a single Trello workspace and reversible.

From the tool's own definition: "Tool name is 'create_card' and description states 'Create a card in a list', which creates new data in Trello. The parameters (pos, due) are for configuration of the new card's placement and deadline."

## Use case

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

## Recommended policy (PolicyLayer)
