Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that it ranks pairs and recommends keep/cut decisions, which implies read-only behavior, but it does not explicitly state whether it modifies data, requires specific permissions, or any side effects. The behavioral disclosure is adequate but not exhaustive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
