WHY IT NEEDS A POLICY

Why linear_create_issue needs a policy

This tool creates new data (a Linear issue) which is a reversible modification—issues can be deleted or archived later. It does not execute arbitrary code, delete data, or move money. Creation of project management artifacts carries medium severity because it could spam a workspace or pollute project data, but the impact is recoverable and localized to the Linear workspace.

From the tool's definition Tool name is 'linear_create_issue' and description states 'Create a new Linear issue', indicating irreversible creation of a new data record in the Linear project management system.
