Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must convey behavioral context, but it only uses the verb 'List' to imply a read-only operation. It does not disclose return format, permissions, prerequisites, or any side effects, leaving significant gaps for operational expectations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
