## Why add_checklist is rated Medium

This is a Write category tool because it creates and modifies data (a checklist) on a Trello card in a reversible manner. The severity is medium because misuse could clutter boards with unwanted checklists, but the action is reversible (checklists can be deleted). Confidence is high because the description clearly indicates a create/modify operation with no side effects beyond the intended checklist creation.

From the tool's own definition: "The tool description states it will 'Create a checklist on a card and optionally seed it with items,' which is a create operation that modifies card state in Trello."

## Use case

AI agents use add_checklist 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.
