Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure, and it discloses nothing: no mention of side effects, prerequisites, what state is mutated, what 'qe' means, or what the operation returns. For a 'set' operation on a video-editing timeline, an agent has zero idea what invoking this tool will actually do.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
