Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate this is a non-read-only, non-destructive, idempotent, open-world operation. The description adds minimal behavioral context beyond annotations—it implies a setup/configuration action via 'POST' but doesn't detail effects (e.g., whether it installs drivers, allocates resources, or requires specific permissions). With annotations covering safety and idempotency, the description adds some value but lacks depth on implementation specifics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
