Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover read-only, idempotent, non-destructive, closed-world. The description adds genuinely new behavioral context: an authenticated Clipform account is required and anonymous sessions will be prompted to sign in. It also discloses a real data limitation (booking, contact, file upload, drawing, camera, payment nodes return counts only), which prevents the agent from promising per-response detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
