WHY IT NEEDS A POLICY

Why create_workspace needs a policy

This tool creates a new workspace, which is a data structure that can be created, modified, or deleted. It has no irreversible destructive effects, does not execute arbitrary code or external operations, and does not involve financial transactions. The blast radius is limited to the user's own workspace quota (max 2 per user) and affects only organizational data structures.

From the tool's definition Tool name 'create_workspace' and description 'Create a new workspace' directly indicate creation of new data structures with reversible effects (workspaces can be deleted or modified).
