WHY IT NEEDS A POLICY

Why update_project needs a policy

This tool modifies existing project metadata (name, description, color, etc.) reversibly. It is Write rather than Execute because it performs straightforward data mutation without triggering external operations or code execution. Severity is medium because misuse could corrupt project organization or metadata, affecting task management workflow, but changes are reversible via subsequent updates or undo.

From the tool's definition Tool name 'update_project' and description 'Update an existing project' indicate modification of existing data in Todoist. The sibling tools show a clear pattern: create_* tools for new items, delete_* tools for removal, and update_* for modification.
