Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry behavioral disclosure. It mentions 'Autonomous' and expected runtime (~20s), and states it returns structured recommendations, but it does not clarify side effects, permissions, or whether it accesses external data. This is a moderate level of transparency but leaves significant unknowns.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
