Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It only says 'List comments' without disclosing whether the operation is read-only, paginated, or requires specific permissions. The presence of a 'dry_run' parameter in the schema is not mentioned, introducing ambiguity about the tool's actual behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
