Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose one useful side effect — that the result is persisted as a note in the notebook — which implies a write operation. But it says nothing about permissions, whether an existing note is overwritten, source requirements, or how long generation takes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
