Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, yet it discloses nothing beyond the verb. It doesn't say whether the deletion is permanent, whether published versions are removed with it, whether a confirmation or special permission is required, or what happens to a webapp that is currently published.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
