Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses the destructive nature ('Archive (delete)') and batch behavior, but lacks critical details: whether archiving is reversible, permission requirements, rate limits, error handling for partial failures, or what 'delete' entails (soft/hard). For a destructive batch tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
