Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'Update multiple notes' which implies a mutation operation, but doesn't disclose behavioral traits such as required permissions, whether updates are atomic or partial, error handling for invalid inputs, rate limits, or what happens to existing note properties not mentioned. This leaves significant gaps 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.
