Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint=true and destructiveHint=false, indicating this is a safe read operation. The description doesn't contradict these annotations, but it also doesn't add meaningful behavioral context beyond what's already implied by 'cancelDeployment'. It doesn't explain what happens to the deployment, whether it's reversible, or what the response looks like. With annotations covering safety, this gets a baseline score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
