Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It adds valuable behavioral context by specifying 'open' (status filter) and 'INDY' (token specificity), but lacks disclosure on pagination, rate limits, authentication needs, or what constitutes an 'open' versus closed position.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
