## Why update_card is rated Medium

This tool modifies card metadata in Trello in ways that can be undone. While it changes data, none of these operations are destructive (permanent deletion) or financial. The severity is medium because misuse by an AI agent could alter task data, due dates, or archive important cards, potentially disrupting workflow, but these changes remain reversible.

From the tool's own definition: "Tool description explicitly states it can 'Update a card's name, description, due date, or closed (archived) state.' The verb 'update' and the reversible nature of these modifications (name, description, due date can be changed back; archiving is reversible…"

## Use case

AI agents use update_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.
