Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are provided, the description bears the behavioral transparency burden. It clearly signals that this is a read-only listing operation on public, non-sensitive content, which is meaningful safety context. It does not mention output format, pagination, ordering, or request-specific constraints, though those gaps are modest for a zero-parameter list tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
