Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states the action 'List' and gives no details about the return format, uniqueness of article numbers, pagination, or absence of side effects. The agent cannot anticipate whether results are deduplicated or how they are structured.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
