Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses two concrete effects ('Release GPU memory' and 'stop the scheduler') and a timing guarantee. However, it does not mention whether the call blocks until jobs finish, whether it is idempotent, or what happens if invoked while jobs are still running.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
