Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full burden. It indicates a read operation ('summarize') and hints at output content (retry/approval gates), but does not explicitly state that it is read-only, describe side effects, or clarify return structure. It adequately discloses core behavior but lacks detail on permissions, errors, or data format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
