Reference Design Contract

Use this skill when the user has taste signals, references, or a rough "like this" request and needs a reusable design contract before generation. The goal is not to write a longer prompt. The goal is to make design decisions explicit enough that a later prototype, deck, redesign, or image-remix run can execute without guessing.

What this skill produces

Create three files:

1. DESIGN.md — the reusable visual direction, following OpenDesign's standard nine-section design-system shape.
2. design-contract.md — the decision record: evidence used, keep/change boundaries, rationale, risks, and quality gate.
3. implementation-handoff.md — concise build instructions for the next artifact-producing skill or coding agent.

If a preview is useful, also create example.html as a small hand-built contract preview. Do not make it the main deliverable.

Workflow

1. Lock the job. Identify target artifact type, audience, brand/product context, references, and constraints. Ask at most two questions only when a missing answer would change the direction. Otherwise choose a sensible default and label it as inferred.
2. Read evidence. Use provided screenshots, URLs, existing DESIGN.md, brand docs, image artifacts, or user notes. If evidence is missing, say so and base the contract on the brief only; do not invent brand facts.
3. Separate reference semantics. For every reference, split it into:
   • Keep: qualities to preserve, such as density, composition, material, typography rhythm, color temperature, or motion attitude.
   • Change: subject matter, copy, brand marks, exact layout, protected assets, and anything the user wants adapted.
   • Do not copy: literal screenshots, logos, claims, pricing, proprietary UI, or exact prompt wording from examples.
4. Freeze the direction. Choose one coherent visual stance. Do not provide five unrelated moodboards. If there are genuinely competing directions, name them briefly, pick the recommended one, and continue.
5. Write DESIGN.md. Use these nine headings exactly:
   • ## 1. Visual Theme & Atmosphere
   • ## 2. Color
   • ## 3. Typography
   • ## 4. Spacing & Grid
   • ## 5. Layout & Composition
   • ## 6. Components
   • ## 7. Motion & Interaction
   • ## 8. Voice & Brand
   • ## 9. Anti-patterns
6. Write design-contract.md. Include:
   • goal and target artifact
   • evidence table with confidence (observed, provided, inferred)
   • keep/change/do-not-copy table
   • final design stance in one paragraph
   • risks and explicit unknowns
   • quality gate checklist
7. Write implementation-handoff.md. Keep it short and operational:
   • files to read
   • token/palette/type/layout constraints
   • asset rules
   • responsive requirements
   • "first artifact should prove..." acceptance notes
8. Validate. Read references/checklist.md and satisfy every P0 gate before final handoff.

Output rules

• Make every claim traceable to user input, observed reference evidence, or an explicitly labeled inference.
• Prefer concrete constraints over adjectives: "one warm accent, no purple or blue glow" beats "premium".
• Treat "do the same style" as "borrow controllable qualities", not "clone the original subject or prompt".
• If the user asks for immediate UI generation too, finish these contract files first, then hand off to the appropriate artifact skill in the next step.
