Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate this is a non-read-only, non-destructive, non-idempotent, open-world operation. The description adds that it's a POST request, implying a state-changing action, but doesn't elaborate on what 'rebuild' entails behaviorally—such as whether it restarts services, reinitializes data, or affects availability. It doesn't contradict annotations, but provides minimal additional context beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
