Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'Retrieve list' which implies a read-only operation, but doesn't disclose behavioral traits like authentication requirements, rate limits, pagination, or what happens if the group parameter is omitted. For a tool with zero annotation coverage, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
