Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states 'Delete', which aligns with the destructiveHint: true annotation. However, it does not elaborate on behavioral traits such as idempotency (whether deleting a non-existent key is safe) or any permissions needed. Since annotations already provide destructive hint, the description adds minimal behavioral context beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
