Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It accurately indicates a read-only operation ('List all installed SSL certificates') without side effects, but it does not mention return format, pagination, or any potential limitations. For a simple list operation this is minimally adequate, though it lacks richer behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
