Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description includes one important behavioral trait: 'Original content is not modified,' indicating non-destructiveness. However, with no annotations, it fails to disclose other relevant behaviors such as authorization requirements, whether a new revision is created in the database, rate limits, or the tool's side effects beyond the note attachment.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
