video-spec-builder
Use when the user says they want to make a video, promotional film, product demo, animated short, Douyin/YouTube content, or says they want to change the storyboard, adjust pacing, swap shots, adjust subtitles, add voiceover, or change transitions. Collect video requirements through Socratic questioning, proactively activate the full capabilities of the rendering layer (TTS / subtitles / 3D / shader / audio-reactive, etc.), and output a standardized video-spec.md for rendering.
