Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It usefully discloses that this mutates Feedbin state, but it does not say what is removed, whether the operation is idempotent, what permissions are required, or what happens to the underlying tag.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
