Make design.md a prerequisite for every composition, not an optional picker step. Step 0a is now "Design system" and must complete before prompt expansion (Step 0b), because expansion output is supposed to cite design.md's palette, typography, and motion energy — expanding first produces generic breakdowns the downstream agents then ignore. Resolution order for design.md: 1. Existing design.md in project root → use as-is 2. Invoke /visual-style skill in Create mode → save output to design.md 3. references/design-picker.md (fallback if user prefers pre-built) 4. house-style.md defaults (only with explicit "skip design") Also expand prompt-expansion.md's scene-breakdown spec to require 2–5 decoratives per scene drawn from house-style's list, each using design.md's palette values. Spells out that "single ambient motion" means one looping motion applied to these decoratives, not one element total — this was the p1 regression root cause in the eval run.

Prompt-expansion.md was re-stating house-style rules in its scene breakdown and negative-prompt sections. That's duplication — if house-style changes, expansion drifts. Fix: - Prerequisites now tell the expansion step to read house-style.md and design.md before generating. The expansion generates output that conforms to those rules; it doesn't re-state them. - Scene breakdown template names the three layer slots (background/midground/foreground) without re-stating the decorative-count rule or palette-compliance rule. - Negative-prompt no longer hard-codes palette/font rules — those live in design.md and house-style.md where they belong. - The "single ambient motion doesn't mean single element" clarification moves to house-style.md where the base rule lives, so any reader sees it next to the rule it clarifies.

Expansion is not about lengthening a short prompt — it's about
grounding the user's intent against design.md and house-style.md
and producing a consistent intermediate that every downstream
agent reads the same way.
Even a fully-detailed user prompt benefits:
- Color words ("warm", "cinematic") → resolved to design.md hex values
- Decorative layers the user forgot → added explicitly per house-style
- Vague transitions → specified as morph operations with duration/ease
tied to design.md energy
- Per-scene timing → verified to sum to stated total
The eval showed p5 (fully-expanded brief) skipping this step and
missing the benefit. When expansion runs on an already-expanded
prompt, it's mostly pass-through, but it still binds the prompt to
design.md and house-style — which is the contract downstream steps
depend on.
Single-scene compositions and trivial edits are the only exceptions.

The p2 eval (sparse prompt, 6 scenes) was dense and alive because expansion had to invent atmosphere and micro-details to fill in the 1-sentence input. The scene subagents then built from that rich spec. p3/p5/p6 (detailed prompts) produced muted output because the expansion was framed as "largely pass-through" for already-detailed inputs. Scene subagents got a thin brief and built thin output. Make expansion always enrich, never pass-through: - Every user prompt is a *seed*, not a spec. Expansion takes what the user wrote and adds atmosphere, ambient motion, micro-details. User's content stays; expansion builds on top. - Scene-by-scene breakdown now enumerates 5 required fields per scene: background (2-5 decoratives with ambient motion), midground, foreground, micro-details (2-3 per scene: registration marks, tick indicators, monospace labels, background data streams, grid patterns), transition morph. - Framing note: the quality gap between a single-pass composition and a multi-scene-pipeline composition comes from this step. If expansion front-loads the richness, every scene subagent builds from a rich brief; every scene comes out alive. Addresses user feedback after the eval review: "the only significant difference I see is in p2" — because p2 was the only case where expansion had to enrich. Making enrichment mandatory everywhere.
