Show four hooks for the creator's idea when they ask for ideas, hooks or a previs, or four beats of the picked hook's story. Work in this order. 1. Find the outliers: query the creator's own reels, and the pool's, for the ones whose numbers run above their usual. 2. Watch the openings: open each outlier's first four seconds, moments 0 to 3.8 spaced 0.2 apart where the reel has stored moments, else seconds 0 to 4, beside the first lines of its transcript. Never write from transcripts alone. 3. Read each hook in the conversation: the move on screen, the words on screen, the spoken line, the beat when each lands, and why it works. 4. Write four hooks that each borrow one move and none of the words: see carries the move as a concrete scene, say the spoken line, on_screen the words, and borrowed_from names the reel, its second and the move. 5. Give each frame three lines of on-screen words, on_screen and two other_words; the card paints the first and offers the rest in its tray. 6. Dally draws the four frames wordless from see and paints on_screen over them; previs.reword changes the words without a redraw and keeps every revision. Write the words for the creator alone: read their own reels' openings before writing, and write about their own work, their own place and their own way of putting things; a voice heard in their reels may not be theirs. If a line could be heard in someone else's reel, it does not go in this one. Never invent experiences, credentials, finances or results; frame an unverified scenario as an idea to film. Never copy example hooks, recycle a past post or pick for the person. Pass three creator image URLs from open as references and describe their actual appearance in character; Dally draws one four-frame sheet with GPT Image 2 low through OpenRouter in the approved marker/gouache style, about twenty seconds and a few cents. For a storyboard pass the picked hooks' parent_id; character, references and format are inherited. Reuse request_key on a retry; a new key buys a new drawing. It answers immediately: show kind previs with this whole response. Short form is 9:16; long form is 16:9.

previs.create
Show four hooks for the creator's idea when they ask for ideas, hooks or a previs, or four beats of the picked hook's story. Work in this order. 1. Find the outliers: query the creator's own reels, and the pool's, for the ones whose numbers run above their usual. 2. Watch the openings: open each outlier's first four seconds, moments 0 to 3.8 spaced 0.2 apart where the reel has stored moments, else seconds 0 to 4, beside the first lines of its transcript. Never write from transcripts alone. 3. Read each hook in the conversation: the move on screen, the words on screen, the spoken line, the beat when each lands, and why it works. 4. Write four hooks that each borrow one move and none of the words: see carries the move as a concrete scene, say the spoken line, on_screen the words, and borrowed_from names the reel, its second and the move. 5. Give each frame three lines of on-screen words, on_screen and two other_words; the card paints the first and offers the rest in its tray. 6. Dally draws the four frames wordless from see and paints on_screen over them; previs.reword changes the words without a redraw and keeps every revision. Write the words for the creator alone: read their own reels' openings before writing, and write about their own work, their own place and their own way of putting things; a voice heard in their reels may not be theirs. If a line could be heard in someone else's reel, it does not go in this one. Never invent experiences, credentials, finances or results; frame an unverified scenario as an idea to film. Never copy example hooks, recycle a past post or pick for the person. Pass three creator image URLs from open as references and describe their actual appearance in character; Dally draws one four-frame sheet with GPT Image 2 low through OpenRouter in the approved marker/gouache style, about twenty seconds and a few cents. For a storyboard pass the picked hooks' parent_id; character, references and format are inherited. Reuse request_key on a retry; a new key buys a new drawing. It answers immediately: show kind previs with this whole response. Short form is 9:16; long form is 16:9.
