Ai To Figma

AI to Figma

Turn a design brief or visual reference into an approved visual direction, rebuild it as validated static HTML, then capture that HTML into an editable Figma Design file.

Core contract

1. Resolve the brief, reference role, delivery target, fidelity mode, and device before creating the task workspace. Open the delivery-target chooser only for missing target fields. In Codex, insert it with the native ::codex-inline-vis directive; do not substitute a visualize content reference or modal form.
2. Scaffold design.md with the resolved mode and without creating index.html. For adaptation and independent planning, establish the visual direction, generate a full-screen preview, iterate without a fixed limit, and stop until the user explicitly approves one version.
3. After explicit approval, persist the selected file under previews/ and run scripts/record-preview-approval.mjs. Reconstruction skips only this full-screen preview gate, not generation of separate final assets.
4. Resolve the local-font Typography Plan, inventory every non-text final visual in the Visual Asset Plan, classify its complexity as structural, flat, or rich, and show both complete decision tables to the user. Never abbreviate away composition, identity, complexity, method, or status. The approved full-screen preview is a reference, not a final asset.
5. Resolve every typography and visual-asset row to ready, validate all required gates, then create index.html with scripts/init-html.mjs. Stop on any blocked item.
6. Rebuild the approved direction with static HTML, inline CSS, separate final assets, and only small amounts of native JavaScript. Mark each planned visual with its data-visual-id; never embed the full-screen preview or introduce React or a remote runtime.
7. Validate the rendered page and its visual-plan mappings locally before requesting a Figma capture.
8. Use Figma MCP generate_figma_design as the delivery path and open only the root-scoped captureUrl emitted by scripts/serve-preview.mjs. Do not silently fall back to use_figma, clipboard HTML, SVG import, or a flat screenshot.
9. Treat every capture ID as single-use. Permit one diagnosed retry with a new capture ID, then stop and report the failure.

Input roles

• Brief: required product/content intent unless the user explicitly requests a literal reconstruction.
• Reference: optional screenshot, local image, or node-specific Figma URL used for reconstruction or visual-language extraction.
• Target: optional prompt input, but required before work begins. Use an explicitly designated Figma Design URL, or resolve the current Figma identity and plan for a new Design file through the delivery-target gate.
• Device: web or mobile. Infer it only when the prompt or reference makes the class unambiguous.

If one Figma URL could be either a reference or a target, ask which role it has. Never guess.

Interpret “recreate”, “restore”, “1:1”, or equivalent language as reconstruction. Interpret “inspired by”, “reference”, or equivalent language as visual-language adaptation. Otherwise plan the interface from the brief.

Required references

• Read references/workflow.md for the state machine and stop conditions.
• Read references/target-resolution.md on every run before creating the task workspace.
• Read references/design-spec.md on every run before creating design.md.
• Read references/typography.md on every run before resolving fonts or creating design.md.
• Read references/reference-modes.md when a screenshot, image, or Figma frame is supplied.
• Read references/canvas-specs.md for the chosen device. Mobile output must include the complete iOS status bar and home-indicator structure.
• Read references/asset-policy.md when the design contains logos, product identity, photos, illustrations, avatars, mascots, or thumbnails.
• Read references/icon-system.md whenever the design contains generic interface icons.
• Read references/transparent-assets.md whenever an asset needs transparency or image generation.
• Read references/html-authoring.md before writing HTML.
• Read references/figma-capture.md immediately before any Figma write.
• Read references/validation-and-recovery.md before final verification or after any failure.

Hard prohibitions

• Do not crop a UI reference screenshot into final asset files.
• Do not generate, invent, or approximately redraw an existing brand or product logo.
• Do not regenerate an identity-critical product, person, package, or mascot and present it as the original.
• Do not use an unvalidated transparent asset.
• Do not generate a keyed background or run local background removal for a GPT Image 2 asset; request native transparency and validate the final alpha output.
• Do not reduce a compositionally dominant hero illustration to generic CSS merely because its silhouette is abstract or geometrically reproducible.
• Do not implement a rich visual with HTML/CSS, inline SVG, MingCute, or device-native structure. Use a file-backed original or image generation.
• Do not substitute SVG or CSS when an image-generation row cannot be resolved. Invoke the runtime image-generation capability or mark the row blocked.
• Do not create index.html before the Visual Asset Plan passes or continue while any visual is planned, resolving, or blocked.
• Do not create index.html before the Typography Plan passes, use a remote or downloaded font, or leave a requested display font unresolved.
• Do not create index.html for adaptation or independent planning before an explicitly approved preview is recorded and its hash validates.
• Do not use the approved full-screen preview in HTML, the Visual Asset Plan, or Figma output; rebuild it as editable structure and separate assets.
• Do not generate or distort an identity-critical logo, person, product, package, mascot, or character in a direction preview. Leave a neutral placeholder or use an authorized original without alteration.
• Do not bake required shadows, backgrounds, UI text, or controls into generated subject images.
• Do not mix MingCute with another generic icon family, use an icon font, retain an icon placeholder, or load icons at page runtime.
• Do not send unreviewed HTML to Figma.
• Do not capture body, html, or the browser viewport; capture only [data-figma-capture-root] through the URL emitted by scripts/serve-preview.mjs.
• Do not claim delivery until the captured node or page has been reread and visually verified.
• Do not create .ai-to-figma/<slug>/ while the delivery target is unresolved or an account switch is pending.
