Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral burden. It discloses what is returned (including the unusual "provenance banner"), which implies a safe read-only operation, but says nothing about cost, permissions, or pagination. Adequate for a zero-parameter read but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
