Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses meaningful behavior: grouping by component, scope over the whole archive, and the need for a key. However, it does not describe return structure, error behavior, or rate limits, leaving significant gaps in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
