Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It transparently discloses that the operation defaults to dry-run and returns a retry build identifier, which is useful. However, it does not clarify what side effects occur outside dry-run, what 'fictional' means, or whether permissions/rate limits apply.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
