Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('Duplicate') but doesn't explain what duplication entails—e.g., whether it copies properties, effects, or keyframes; if it requires specific permissions; or what the expected outcome is. This leaves significant gaps for an AI agent to understand the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
