Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It only states the action 'Delete an attachment' without disclosing side effects, irreversibility, required permissions, or what happens to the attachment or dependent data. It adds no behavioral context beyond the imperative verb.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
