Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate no read-only, open-world, idempotent, or destructive hints, leaving the description to carry behavioral context. The description does not disclose potential side effects like creating a node in the scene tree, or whether the operation can be undone. It does not mention any important behaviors such as automatic node naming conflicts or scene attachment details. There is no contradiction with annotations, but coverage is weak.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
