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 the mechanism (sending Ctrl-C) and the expected effect (interrupting processing), which is useful behavioral context. However, it doesn't state whether the interruption is graceful, whether state is preserved, what happens if no process is running, or what the output contains. Some behavioral transparency is present but significant gaps remain.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
