Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate a non-read-only, non-destructive, non-idempotent mutation. The description 'Unarchive a project' adds no behavioral context beyond that, such as side effects, permission requirements, or what state changes occur. It does not contradict annotations, but also does not enrich them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
