Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden of disclosing behavioral traits. It only states 'create a new OneNote notebook' without mentioning side effects, permissions, default storage location, or whether the operation is idempotent. This is minimal and lacks the context an agent might need for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
