Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It states 'list' implying read-only, but does not mention side effects, error handling, or authentication needs. The description is minimal and does not provide adequate transparency for an agent to understand the tool's behavior beyond the basic operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
