Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint, covering the safety and repeatability profile. The description adds useful context by clarifying that all document types, binaries, and folders are included, but it does not disclose potential pagination behavior or return format. With annotations present, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
