Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden of behavioral disclosure. It only says 'set anti alias quality' without revealing prerequisites (e.g., open project/sequence), what object's setting is changed, whether it affects rendering or export, or any side effects. This is nearly complete opacity for a mutation-like operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
