Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It communicates recency, pagination, and workspace filtering, but it does not clarify the sort semantics of 'recent', whether the operation is read-only, or the default behavior when workspace_name is omitted. These are moderate gaps for a listing tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
