Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. The verb 'Get' clearly indicates a safe, read-only operation. It also discloses what data is returned (document counts, reference statistics, working group assignments), which is useful behavioral context. It does not mention caveats like pagination or performance, but for a simple overview query this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
