Why release_host_reservation is rated Medium

This tool modifies infrastructure by releasing a previously made host reservation, which is a reversible Write operation.

The blast radius is moderate as it could affect resource availability and scheduling if misused, but the operation is reversible.

From the tool's definition Tool name is 'release_host_reservation' which modifies infrastructure state by releasing a reservation. Description states 'Release host reservation' indicating a state change operation.
