Vue d’ensemble

Reverse-engineer a website's visual design system from a URL and produce a fully spec-compliant DESIGN.md file (https://github.com/google-labs-code/design.md). The output includes both machine-readable YAML design tokens (colors, typography, spacing, rounded corners, components) and human-readable markdown rationale sections (Overview, Colors, Typography, Layout, Elevation & Depth, Shapes, Components, Do's and Don'ts). Use this skill whenever the user wants to generate a DESIGN.md, create a design system file from a website, capture a site's visual identity, extract design tokens, build a design spec from a URL, clone a site's look and feel, or scaffold a DESIGN.md from scratch. Also triggers on: 'design system from URL', 'generate DESIGN.md', 'extract colors from site', 'what are this site's design tokens', 'capture design from website'.

DESIGN.md Creator

Reverse-engineer a website's visual design system and produce a fully spec-compliant DESIGN.md file following the google-labs-code/design.md format.

What this produces

A DESIGN.md file with two layers:

YAML frontmatter — machine-readable design tokens: colors, typography, spacing, rounded corners, components
Markdown body — human-readable rationale for each design decision, in 8 canonical sections

The output is ready for agents to consume immediately — no post-processing needed.

Step 1: Get the URL

If the user provided a URL via $ARGUMENTS, use it. Otherwise ask:

What website should I reverse-engineer? Provide the URL and I'll generate a DESIGN.md from its visual design.

Optionally, also tell me:

Where to save the file (default: DESIGN.md in the current directory)

Whether this is a dark-mode or light-mode site (I'll detect this automatically if you don't know)

Any specific components you want captured (buttons, cards, inputs, nav, etc.)

Wait for the URL before proceeding.

Step 2: Fetch and analyze the site

Fetch the page and all significant visual signals:

Fetch the main URL — use whichever method your agent environment supports:
- curl (works in any agent with shell access): curl -sL --max-time 15 -A "Mozilla/5.0" "<URL>" — captures raw HTML including <style> blocks and inline CSS
- webfetch tool (if your agent provides it natively): use it directly for cleaner content extraction
- If the initial fetch returns no CSS (JS-heavy SPA), also fetch the page's linked .css files: extract <link rel="stylesheet" href="..."> URLs from the HTML, resolve each href to an absolute URL using the page's final URL after redirects (e.g., /assets/app.css → https://example.com/assets/app.css, //cdn.example.com/app.css → https://cdn.example.com/app.css), de-duplicate, then curl each one
Identify key sub-pages — if the site has a component library, style guide, or "About" page, fetch those too (up to 2–3 additional pages) to improve coverage
Look for existing design system artifacts — check for /design-tokens.json, /tokens.json, tailwind.config.js, or any design system links in the page source

What to extract from the fetched content:

Signal	Where to look
Brand colors	CSS variables (`--color-*`, `--primary`, etc.), inline styles, og:image colors, logo
Typography	`font-family`, `font-size`, `font-weight`, `line-height`, `letter-spacing` in CSS
Spacing scale	`--spacing-*`, padding/margin patterns, grid gutter values
Corner radii	`border-radius` values across buttons, cards, inputs
Elevation	`box-shadow`, `backdrop-filter`, `z-index` layering patterns
Component styles	Button, card, input, nav, badge styles from class names or CSS
Design personality	Logo, imagery, copy tone, overall layout density

Note: You're inferring from observed CSS/HTML. Be honest about what you can directly observe vs. what you're inferring from visual patterns. Dark-mode sites typically have low-luminance surface colors and high-contrast text; light-mode sites are the inverse. When you can't determine an exact hex value, make a design-coherent choice and note it in the prose.

Step 3: Build the DESIGN.md

Read references/design-md-spec.md for the complete token schema and section rules.

Token extraction rules

Colors — Extract the site's full color role set. At minimum:

primary — main brand/action color
secondary — supporting accent or secondary brand color
neutral / surface — background/surface color
on-primary, on-surface — text colors on those surfaces
Include semantic colors if detectable: error, warning, success
Name tokens semantically (primary, secondary, tertiary, neutral) or use Material Design role names if the site uses a Material-style palette

Typography — Identify the main type scale. Typically 5–12 levels:

Display/headline levels (large, impactful headings)
Body levels (body-lg, body-md, body-sm)
Label levels (captions, tags, small UI text)
Include all detectable properties: fontFamily, fontSize, fontWeight, lineHeight, letterSpacing
Dimensions must include units: px, em, or rem

Spacing — Extract the spacing scale. Common pattern: a base unit (4px or 8px) with named steps: xs, sm, md, lg, xl. Also include layout-specific values like gutter, margin, container-max.

Rounded — Extract corner radius values. Name them: sm, DEFAULT, md, lg, xl, full (for pill shapes).

Components — Capture 4–8 key components. For each, include as many valid properties as observed: backgroundColor, textColor, typography (token ref), rounded (token ref), padding, height, width. Use token references like {colors.primary} instead of hardcoded hex values wherever possible. Include hover variants as separate entries (e.g., button-primary-hover).

Sections to write

Write all 8 sections in canonical order. Each section combines YAML tokens (defined in frontmatter) with prose rationale. For sections where tokens aren't applicable (Elevation, Shapes, Do's and Don'ts), write prose only.

Overview — Brand personality, target audience, emotional tone, design style (flat, glassmorphism, neumorphism, material, etc.), key design decisions. 2–4 sentences that give a coherent aesthetic picture.
Colors — Describe the role of each color palette entry. What does each color mean in the design? When is it used? Reference the token names.
Typography — Describe the font strategy: which typefaces, why they were chosen, how the scale is organized, any special treatments (tight tracking on headlines, text-shadow on dark backgrounds, etc.).
Layout — Grid system (fluid, fixed, 12-column?), spacing philosophy (8px grid, dense vs. airy), max-width, container strategy.
Elevation & Depth — How visual hierarchy is communicated: shadows, tonal layers, glassmorphism, borders, z-axis layering. If flat design, describe what replaces shadows.
Shapes — Corner radius philosophy: sharp/technical, soft/organic, fully rounded pills, mixed. Which components use which radius.
Components — Walk through the key component tokens and explain the design rationale for each group (action elements, containers, inputs, typography application).
Do's and Don'ts — 3–5 concrete rules for maintaining design consistency. Things like "always use {colors.primary} for CTAs, never {colors.secondary}" or "never use pure black (#000000) for text — use on-surface".

YAML frontmatter structure

  ...
spacing:
  base: <Npx>
  ...
components:
  button-primary:
    backgroundColor: "{colors.primary}"
    ...
  ...
---

Step 4: Validate and save

After generating the content:

Self-check these things before writing the file:
- All token references ({path.to.token}) resolve to a defined token
- Color values start with # followed by 6 hex digits
- All dimension values have units (px, em, rem) — no bare numbers except: font weights, unitless line-height multipliers, and spacing values (which may be unitless ratios or column counts per the spec)
- Section order matches the canonical order (Overview → Colors → Typography → Layout → Elevation & Depth → Shapes → Components → Do's and Don'ts)
- Component properties: canonical keys (backgroundColor, textColor, typography, rounded, padding, size, height, width) pass the linter silently; unknown keys are accepted by the spec but will produce a linter warning — flag them in the confidence notes
Check for an existing file at the target path before writing:
- If DESIGN.md (or the user-specified path) already exists, warn the user: "A DESIGN.md already exists at this path. Overwrite, save as DESIGN-<site-name>.md, or cancel?" Wait for their choice before writing.
- If no file exists, proceed directly.
Save the file as DESIGN.md in the current working directory (or the path the user specified).
Tell the user what was generated:

DESIGN.md saved.

Design system: [Name]
Style: [e.g., Glassmorphism / Flat / Material / Custom]
Colors: [N tokens] — [brief palette description]
Typography: [N levels] — [font family names]
Components: [list of captured components]

Confidence notes:

[Any values that were inferred rather than directly observed]

[Any sections that had limited CSS data and required design judgment]

Want me to refine any section, add more components, or lint the file with npx @google/design.md lint DESIGN.md?

Recovery

Situation	How to handle
`webfetch` not available	Fall back to `curl -sL --max-time 15 -A "Mozilla/5.0" "<URL>"` — available in any agent with shell access
Site blocks fetch (403/429)	Ask user to paste relevant CSS, screenshot, or describe the design manually
JS-heavy SPA with no inline CSS	Fetch the JS bundle URL if visible; also try fetching linked `.css` files directly; ask user for computed styles or a screenshot as a last resort
Can't determine exact hex values	Make design-coherent color choices; note them as "inferred" in prose and confidence notes
Site uses a known design system (Material, Ant, Chakra, Tailwind UI)	Note this in the Overview — tokens will align with that system's defaults
No typography found	Default to system fonts (Inter, -apple-system) and note it
User wants lint	Run `npx @google/design.md lint DESIGN.md` and surface any errors/warnings

Rules

Never fabricate specific brand hex values with false certainty — if you inferred a color, say so
All token cross-references must point to defined tokens — no dangling refs
Dimensions must always have units (exception: unitless lineHeight multipliers like 1.5 are valid)
The YAML frontmatter is normative; prose is explanatory context — don't contradict one with the other
Output goes in the current working directory as DESIGN.md unless the user specifies otherwise
If a section has genuinely no applicable content (e.g., a flat design with no elevation), include it briefly and explain: "This design system uses flat tonal layering rather than shadows — see Colors for the tonal surface stack"

# DESIGN.md Creator

Reverse-engineer a website's visual design system and produce a fully spec-compliant `DESIGN.md` file following the [google-labs-code/design.md](https://github.com/google-labs-code/design.md) format.

When you can't determine an exact hex value, make a design-coherent choice and note it in the prose.

## Step 3: Build the DESIGN.md

Read `references/design-md-spec.md` for the complete token schema and section rules.

### Token extraction rules

**Colors** — Extract the site's full color role set. At minimum:
- `primary` — main brand/action color
- `secondary` — supporting accent or secondary brand color  
- `neutral` / `surface` — background/surface color
- `on-primary`, `on-surface` — text colors on those surfaces
- Include semantic colors if detectable: `error`, `warning`, `success`
- Name tokens semantically (`primary`, `secondary`, `tertiary`, `neutral`) or use Material Design role names if the site uses a Material-style palette

**Typography** — Identify the main type scale. Typically 5–12 levels:
- Display/headline levels (large, impactful headings)
- Body levels (body-lg, body-md, body-sm)
- Label levels (captions, tags, small UI text)
- Include all detectable properties: `fontFamily`, `fontSize`, `fontWeight`, `lineHeight`, `letterSpacing`
- Dimensions must include units: `px`, `em`, or `rem`

**Spacing** — Extract the spacing scale. Common pattern: a base unit (4px or 8px) with named steps: `xs`, `sm`, `md`, `lg`, `xl`. Also include layout-specific values like `gutter`, `margin`, `container-max`.

**Rounded** — Extract corner radius values. Name them: `sm`, `DEFAULT`, `md`, `lg`, `xl`, `full` (for pill shapes).

**Components** — Capture 4–8 key components. For each, include as many valid properties as observed: `backgroundColor`, `textColor`, `typography` (token ref), `rounded` (token ref), `padding`, `height`, `width`. Use token references like `{colors.primary}` instead of hardcoded hex values wherever possible. Include hover variants as separate entries (e.g., `button-primary-hover`).

### Sections to write

Write all 8 sections in canonical order. Each section combines YAML tokens (defined in frontmatter) with prose rationale. For sections where tokens aren't applicable (Elevation, Shapes, Do's and Don'ts), write prose only.

1. **Overview** — Brand personality, target audience, emotional tone, design style (flat, glassmorphism, neumorphism, material, etc.), key design decisions. 2–4 sentences that give a coherent aesthetic picture.

2. **Colors** — Describe the role of each color palette entry. What does each color *mean* in the design? When is it used? Reference the token names.

3. **Typography** — Describe the font strategy: which typefaces, why they were chosen, how the scale is organized, any special treatments (tight tracking on headlines, text-shadow on dark backgrounds, etc.).

4. **Layout** — Grid system (fluid, fixed, 12-column?), spacing philosophy (8px grid, dense vs. airy), max-width, container strategy.

5. **Elevation & Depth** — How visual hierarchy is communicated: shadows, tonal layers, glassmorphism, borders, z-axis layering. If flat design, describe what replaces shadows.

6. **Shapes** — Corner radius philosophy: sharp/technical, soft/organic, fully rounded pills, mixed. Which components use which radius.

7. **Components** — Walk through the key component tokens and explain the design rationale for each group (action elements, containers, inputs, typography application).

8. **Do's and Don'ts** — 3–5 concrete rules for maintaining design consistency. Things like "always use `{colors.primary}` for CTAs, never `{colors.secondary}`" or "never use pure black (#000000) for text — use `on-surface`".

Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Reverse-engineer a website's visual design system from a URL and produce a fully spec-compliant DESIGN.md file (https://github.com/google-labs-code/design.md). The output includes both machine-readable YAML design tokens (colors, typography, spacing, rounded corners, components) and human-readable markdown rationale sections (Overview, Colors, Typography, Layout, Elevation & Depth, Shapes, Components, Do's and Don'ts). Use this skill whenever the user wants to generate a DESIGN.md, create a design system file from a website, capture a site's visual identity, extract design tokens, build a design spec from a URL, clone a site's look and feel, or scaffold a DESIGN.md from scratch. Also triggers on: 'design system from URL', 'generate DESIGN.md', 'extract colors from site', 'what are this site's design tokens', 'capture design from website'.
