Why update_leader needs a policy

As an update operation, changes are reversible (data can be modified again or reverted), distinguishing it from destructive deletion. The blast radius is medium—incorrect updates could disrupt tour operations, but no data is permanently lost and corrections are possible.

From the tool's definition Tool name 'update_leader' and description 'Actualizar un guía' (Update a guide) indicate modification of existing guide/leader data. The verb 'update' and context of modifying travel program entities confirms reversible write operation.
