Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description does substantial lifting: it discloses the price ($0.0102 via x402), the failure-billing policy (uncharged on 422/unreachable), and what the result contains (fixed vs. regressed findings). It omits auth requirements and what happens when the report_id is older than 30 days, which keeps it from a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
