Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full burden. It discloses the payload contents but says nothing about side effects, permissions, caching or whether the result is a fixed document — reasonable for a zero-parameter metadata read, but it leaves the agent to infer that the call is safe and free.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
