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 ('trigger') but doesn't explain what 'trigger' entails—e.g., whether it advances slides immediately, requires specific permissions, has side effects like pausing media, or what happens if no presentation is active. This leaves critical behavioral traits unspecified 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.
