Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the read-only, non-destructive, non-open-world annotations, the description discloses ordering (newest to oldest), expiry (feedback tasks and findings expire 30 days after creation), pagination behavior (empty page with continuation cursor), and the semantic distinction that feedback summaries are recorded states rather than live polling. These are substantive behavioral details the annotations do not cover.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
