Start the prompt with the artifact: “six-panel storyboard contact sheet, rough graphite, no written text.” Then define the character and location anchors once. List panels in intended reading order with a shot size, visible action, and new information. End by repeating global constraints such as wardrobe, recurring props, weather, screen direction, blank margins, and the absence of captions or logos. This structure cannot force perfect compliance, but it makes omissions and drift easier to diagnose.
Use concrete continuity nouns rather than stylistic synonyms. If the coat is mustard yellow, the bicycle has a front basket, and the dog wears a red scarf, repeat those exact anchors. A creative-writing instinct to vary “coat,” “jacket,” and “rain shell” can become three different garments. Keep emotional direction observable: lowered shoulders, withheld eye contact, clenched fingers, or a pause at the doorway. Avoid naming protected films, living artists, or copyrighted characters as shortcuts for the look.
When a result fails, revise one class of problem at a time. If order is wrong, simplify the number of panels and restate progression. If identity drifts, reduce the cast and repeat anchors. If geography changes, provide a simpler layout and fewer reverse angles. If every frame is the same size, assign a purpose and shot size explicitly. Changing story, cast, camera, rendering, and palette together makes the next output hard to evaluate.
