Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses that deletion can be permanent or move to trash, which is useful behavioral context. However, it doesn't mention permissions required, whether deletion is reversible, rate limits, or what happens to linked data (e.g., comments, backlinks). For a destructive operation with zero annotation coverage, this leaves significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
