## Why actual_tags_update is rated Medium

This tool creates or modifies data in a reversible manner (update operation), fitting the Write category. Severity is medium because misuse could corrupt financial categorization schemes or confuse budget tracking, but the changes are not irreversible and do not move money. Confidence is high given the explicit 'Update' language in both name and description.

From the tool's own definition: "Tool name is 'actual_tags_update' and description states 'Update an existing tag in Actual Budget,' which modifies data reversibly. Tags can be updated with new values for tag name, color, or description, and these changes can be undone by updating again."

## Use case

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