Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description adequately discloses the idempotent nature, state transition, and specific error conditions (NOT_APPLIED, NOT_FOUND). It does not mention side effects like notifications or authorization requirements, but covers the core behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
