Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the mutation ('Create') and the kind constraint, but it does not explain side effects, idempotency, permissions, or what happens after creation. For a create operation, more context about impact is expected.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
