Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It does state 'permanently', implying irreversibility, which is a key behavioral fact. However, it does not mention potential side effects (e.g., removal of associated data), permission requirements, or error conditions, leaving a significant gap 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.
