Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true and readOnlyHint=false, conveying the tool's mutating nature. The description adds no further behavioral context (e.g., what happens to in-flight jobs, whether it's reversible). With annotations covering the core safety profile, a score of 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
