Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark the tool as destructive and idempotent. The description adds the HTTP method and endpoint, but does not disclose any additional behavioral details such as cascading effects, error handling, or idempotency guarantees beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
