WHY IT NEEDS A POLICY

Why create_absence needs a policy

This tool creates a new record (absence/leave request) in the Sanka system, which is reversible through updates or deletion by authorized parties. It modifies business state (employee availability) but does not execute arbitrary code, delete data permanently, move money, or trigger external systems directly.

From the tool's definition Tool name 'create_absence' and description 'Create a leave or absence request' directly indicate data creation. The verb 'Create' and the action of submitting an absence request are characteristic of Write operations.
