Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. The verb 'List' implies a read-only operation, which is a basic behavioral trait, but it does not disclose any details about return format, pagination, authentication, or rate limits. While the safety is implied, richer behavioral context is missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
