Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure. It only says 'Load' but does not mention side effects (e.g., replacing an existing clip), required permissions, error behavior for missing files, or whether the clip is added to the current scene. This is insufficient for an agent to anticipate outcomes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
