Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds context about the response contents, including 'all visible stages' and 'next move', which goes beyond annotations without contradicting them. No side effects or special behavior are mentioned, but for a read tool that is acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
