Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true. The description adds that it ends Unity.exe processes without affecting the Hub, and that confirm=true is required. This provides useful context beyond the annotations, though more detail on process termination behavior (e.g., unsaved changes) would be beneficial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
