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. It states the action ('reject') but doesn't explain what rejection entails (e.g., irreversible cancellation, permission requirements, or effects on the request). This leaves significant gaps in understanding the tool's behavior and implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
