Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden. It discloses a key behavioral trait: deletion cascades to all documents within the collection. However, it does not mention permanence, required permissions, or any other side effects (e.g., on shares or comments), leaving significant unknowns for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
