Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. It usefully reveals that deleting the watch item also deletes its history, which is an important side effect. However, it does not state irreversibility, permission requirements, or effects on active watch jobs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
