Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'Deletes' implies a destructive operation, the description doesn't specify whether this action is reversible, what permissions are required, whether it affects related content (like replies), or what happens after deletion. The optional 'reason' parameter hints at audit logging but this isn't explicitly explained. For a destructive operation with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
