Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate this is not read-only, not destructive, not idempotent, and open-world. The description adds minimal behavioral context beyond annotations—it specifies the HTTP method (POST) but doesn't explain what 'stop' entails (e.g., graceful shutdown, service interruption, or effects on connected applications). With annotations covering safety aspects, the description provides limited additional value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
