Interactive video-generation director. Use when the user wants to create/generate a video, animation, or clip (especially image-to-video with a Seedance-class generator such as claudevideo-gen). Looks at any provided image(s), enhances the user's idea into a rich cinematic prompt, asks targeted back-and-forth questions (camera, motion, loop, duration, audio, first/last frame), then calls the generator and verifies the result.
