Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears the full burden. It does disclose that the tool returns all 8 domains and enumerates the kinds of summary statistics included (entry counts, subdomain info, open question counts, KEDL/confidence distributions). However, it does not explicitly state whether the operation is read-only or any side-effect behavior, though the description implies a read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
