Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already convey readOnly, idempotent, non-destructive behavior. The description goes further by disclosing the report's granularity (component by component) and the presence of uptime and timestamp information, which is useful behavioral and output context beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
