Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already convey that this is a write operation, idempotent, and non-destructive. The description adds the notion of a 'flow' but does not disclose details about valid transitions or side effects. With annotations present, the description provides minimal but non-contradictory additional context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
