Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It merely names the operation without explaining what 'item' refers to (e.g., a project item or source monitor clip), whether a selection is required, or any side effects. This is a slight improvement over a pure tautology but still lacks meaningful behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
