Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already communicates that this is a read-only operation, so the description does not need to repeat that. However, the phrase 'when possible, refresh' introduces ambiguity about what refresh means (e.g., triggering a regeneration vs. refreshing local status), and no additional side effects or limitations are disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
