Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations (readOnlyHint: true, destructiveHint: false, idempotentHint: true, openWorldHint: true) already indicate this is a safe, read-only, idempotent operation that may return partial results. The description adds minimal value by including '(GET)', which aligns with read-only behavior but doesn't contradict annotations. However, it lacks additional context such as rate limits, authentication needs, or what 'all' entails (e.g., pagination, filtering).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
