Generates and prompts video clips on the filmmaking canvas. Use when the user asks to generate, render, animate, continue, restyle, edit, shoot, or compose a video clip; render script or shot notes as video; animate a storyboard, starting frame, image, character, location, or reference; use image, video, audio, storyboard, starting-frame, or voice refs; compose an ad, brand film, product promo, music-video shot, or video sequence; or before calling generate_video.js. Owns video CLI flags, refs, prompt construction, audio-ref handling, and video-specific failure hints.
>- Generates/edits filmmaking canvas images via generate_image.js and generate_image_pro.js. Use before image CLIs for character/location design, refs, starting frames, storyboards, stills, edits, variations, and downstream video anchors. Video-bound characters default to Pattern 7 4-panel sheets; one-off static portraits use Pattern 1. Story/script breakdowns should create detailed location anchors plus material character/location variants. Storyboards
Designs and attaches voice samples or final narration/line audio on the filmmaking canvas via the local generate_voice.js CLI. Use before calling generate_voice.js; when the user asks to give a character a voice, preview how a character sounds, create reusable timbre anchors for every speaking character or VO/narration, or create exact narration/VO/final line audio.
>- Orchestrates story, script, screenplay, concept, product promo, and multi-shot idea work into finished video. Use first when the user asks to make a video from a story or script; asks what next in a story video project; or needs a decision spanning script splitting, image refs, voices or VO, video clips, render strategy, Timeline ordering, or final Timeline handoff. Routes execution to script-compose, image-compose, voice-compose, and video-compose before those skills' CLIs are used.
>- Handles explicit screenplay/story work on the filmmaking canvas. Triages screenplay (use verbatim), story/concept (iterate then rewrite), or neither (defer). Captures the final script note/title; on explicit command, splits into <=15s shot notes and extracts characters, variants, locations, and speaking/VO needs. Use for writing, adapting, rewriting, splitting, analyzing, or breaking down scripts/stories. Preserves dialogue verbatim and returns multi-stage planning to story-to-video-workflow before media generation. Does not split/analyze on file drop or without explicit intent.
Designs and maintains semantic groupings and readable layouts on the filmmaking canvas — scenes, character-reference sets, act beats, and other titled visual frames. Use when nodes on the canvas cluster around a shared meaning and would read more clearly if arranged together and wrapped in a frame. Don't force it — groups are a view concern, not an organizing tax.
