Why update_plane_project needs a policy

The tool updates/modifies project data reversibly in Plane, which is a Write operation. It does not execute arbitrary code, delete data, or trigger financial transactions. Severity is medium because project metadata updates could affect team workflows or visibility, but changes are reversible. Confidence is high as the intent is explicit in both name and description.

From the tool's definition Tool name 'update_plane_project' and description 'Update an existing project in the Plane project management system' indicate modification of existing data.
