Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full behavioral disclosure. It transparently states that the operation deletes audio and leaves silence, which is the key behavioral trait. It does not mention undo or other side effects, but the destructive nature is evident from 'Delete', and the silence behavior is clearly disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
