WHAT IT DOES

WHY IT NEEDS A POLICY

Why linear_create_issue needs a policy

Creating an issue is a reversible write operation—new issues can be updated or deleted later. It modifies the Linear system state by adding a new record, but does not destroy data or execute arbitrary code. The severity is medium because uncontrolled issue creation could spam a project tracking system or create misleading records, but the impact is contained and reversible.

From the tool's definition Tool name 'linear_create_issue' and description 'Create a new Linear issue' explicitly indicate the tool creates a new data record in the Linear issue tracking system.
