Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Delete' implies a destructive mutation, but it doesn't disclose critical behaviors: whether deletion is permanent, requires specific permissions, affects associated data (e.g., documents, agents), or has confirmation steps. This is inadequate 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.
