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 indicates a read-like verification but uses 'recompute' which could imply mutation. It does not clarify side effects, required input state, or behavior on mismatch. For a verification tool, more transparency is needed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
