Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavior disclosure burden. It does add meaningful behavior by stating the cancellation is a clean exit at the nearest stage boundary, but it does not mention side effects, whether the cancellation is reversible, what happens to partial results, or whether the call is synchronous.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
