Skill: Frame Chaining (Visual Continuity)

What

Every panel after panel-01 receives the previous panel's actual generated pixels. The prompt describes ONLY what changed. The chain carries visual identity forward.

How It Works

{
  "panel_id": "panel-05",
  "ref_panels": ["panel-04"],
  "prompt_text": "Same scene. She is now pulling herself onto the bed..."
}

The generate.py script:

Loads panel-04's PNG
Sends it as image input with continuity instruction
Sends the text prompt describing the delta
The model sees what came before and modifies it

Rules (Non-Negotiable)

Panel-01 has NO ref_panels — it's the establishing shot. Full description needed.
Every subsequent panel references the previous: "ref_panels": ["panel-{N-1}"]
Every chained prompt MUST start with "Same scene" — this is load-bearing. Drop it and the model generates a completely different environment.
Describe the DELTA, not everything — the model can SEE the previous frame. Don't re-describe the room, the lighting, the characters' outfits. Just say what MOVED.
Reduce object ambiguity — "the blue plastic chair she was sitting on" not "the chair." Multiple instances of the same object type confuse the model.
Generation MUST be sequential — panel-05 needs panel-04 to exist first. --all runs sequentially.
If regenerating panel-05, also regen panel-06+ — the chain is broken. Everything downstream inherits from the broken link.

Prompt Style Comparison

❌ Without chaining (full description every time):

"A hospital room with warm light from the window. A 28-year-old South Asian woman in an NHS blue gown sits propped on pillows in a hospital bed holding a newborn. A 3-year-old girl in purple pajamas with a butterfly clip is pulling herself onto the bed..."

✅ With chaining (delta only):

"Same scene. The toddler is now pulling herself up onto the hospital bed, small hands gripping the white sheet, bunny slippers dangling as her feet leave the floor."

Chain Drift

Over long sequences (15+ panels), visual details can drift. Mitigation:

Object reference PNGs are sent alongside EVERY prompt (via characters field)
The object refs act as anchors even when the chain drifts
PRO model panels re-establish quality that cheap panels inherit
