Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description clarifies that the operation is non-cascading and permanent, which is critical behavioral information beyond what the annotations provide. However, it doesn't mention failure cases, return behavior, or idempotency, which would be relevant for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
