Design DNA

A 3-phase workflow for extracting, structuring, and applying design identity across three dimensions:

Design System — measurable tokens (color, typography, spacing, layout, shape, elevation, motion, components)
Design Style — qualitative perception (mood, visual language, composition, imagery, interaction feel, brand voice)
Visual Effects — special rendering (Canvas, WebGL, 3D, particles, shaders, scroll effects, cursor effects, SVG animations, glassmorphism, etc.)

Phases

Phase 1: Structure — Output the Schema

When the user asks for the structural dimensions or schema:

Read references/schema.md
Present the full schema with field descriptions
Explain the three dimensions and their roles:
- design_system: What you can measure — exact hex values, pixel sizes, rem scales
- design_style: What you can feel — mood, personality, composition strategy
- visual_effects: What you can see but can't express in CSS alone — WebGL scenes, particle systems, shader distortions, scroll-driven animations
Ask if the user wants to customize or extend any dimensions

Phase 2: Analyze — Extract DNA from References

When the user provides images, screenshots, or links representing a target design style:

Read references/schema.md for the full field list
For each reference provided:
- If image/screenshot: first run the deterministic color measurement (see below), then analyze the remaining visual properties directly
- If URL: fetch and analyze the page's visual design
For every field in the schema, extract or infer a value from the references
When multiple references conflict, note the dominant pattern and mention variants
Output a complete Design DNA JSON — every field populated, no empty strings
After output, ask: "Want to adjust any values before using this for generation?"

Analysis approach per dimension:

Dimension 1: design_system

color: Do not estimate hex values by eye — perceived colors drift toward familiar palette defaults (often by a ΔE of 10+). When the reference is an image file, measure instead. Resolve SKILL_ROOT to the absolute directory containing this SKILL.md; never assume the current project directory contains the skill's scripts/ folder. Use absolute paths for the reference and output, and keep one uniquely named measurement file per reference:
```
npm install --prefix "$SKILL_ROOT/scripts" --silent
node "$SKILL_ROOT/scripts/measure-colors.mjs" "$REFERENCE_IMAGE" > "$MEASUREMENT_JSON"
```
Use the measured hexes verbatim in the DNA JSON: map the background role to surface.background; map text to the end of neutral.scale that contrasts with the measured background and document that foreground use in neutral.usage; and map accent to accent.hex. Keep both the measured palette and its measurement configuration in design_system.color.measured_palette and design_system.color.measurement so verification can reuse the same clustering configuration. Coverage values are fractions from 0 to 1. Only fall back to visual sampling when measurement is impossible (for example, a URL-only reference that cannot be screenshotted). Choose primary and secondary colors by semantic role, use accent for CTA emphasis, and order the neutral scale from lightest to darkest regardless of theme.
typography: Identify font families by visual characteristics (geometric, humanist, serif class). Estimate scale ratios from heading/body size relationships.
spacing: Assess density by element proximity. Measure rhythm by section gap consistency.
layout: Identify grid by content alignment patterns. Note max-width, column count, asymmetry.
shape: Measure border-radius by comparing to element height. Note border and divider presence.
elevation: Classify shadow softness, spread, and layering approach.
motion: If observable (video/interactive), note easing curves and duration feel.

Dimension 2: design_style

Synthesize holistic impressions — mood, personality, composition strategy
Compare against genre archetypes (SaaS, editorial, brutalist, etc.)
Note ornamentation level and whitespace philosophy

Dimension 3: visual_effects

From code: Scan for <canvas>, WebGL contexts, Three.js/Pixi.js imports, GSAP/Lottie usage, custom shaders, IntersectionObserver scroll triggers, SVG <animate> elements
From screenshots: Describe visible effects that go beyond standard CSS — glowing particles, 3D object renders, noise textures, gradient animations, parallax depth, cursor trails, text distortions, glassmorphic surfaces. Note these in composite_notes when exact implementation can't be determined.
From video/interaction demos: Note scroll behaviors, hover distortions, transition choreography, loading sequences
Set enabled: false for any effect category not present in the reference
Rate overview.effect_intensity and overview.performance_tier based on what's observed

Phase 3: Generate — Apply DNA to Content

When the user provides DNA JSON + content to design:

Read references/generation-guide.md
Parse the DNA JSON and extract all tokens across three dimensions
Build CSS custom properties from design_system values
Apply design_style qualitative fields to guide subjective design decisions
When the design needs assets or source materials, fetch them from the original source whenever possible. If the user provided a URL, retrieve the real asset from that URL instead of recreating, approximating, or substituting it.
Implement visual_effects using appropriate technologies:
- Lightweight effects → CSS animations, SVG, vanilla JS
- Medium effects → Canvas 2D, GSAP, Lottie
- Heavy effects → Three.js, custom GLSL shaders, Pixi.js
Generate the design output (default: self-contained HTML with inline CSS/JS)
Run quality checks from the generation guide
Verify (when the DNA contains a measured palette): save the current Design DNA JSON if it is not already a file, screenshot the generated output, then score it against that DNA file. Resolve SKILL_ROOT from this SKILL.md and use absolute paths; do not assume a temporary file named measured-colors.json exists:
```
node "$SKILL_ROOT/scripts/verify.mjs" "$IMPLEMENTATION_SCREENSHOT" "$DESIGN_DNA_JSON"
```
A standalone measurement JSON may be used instead of the DNA file when that is the only persisted artifact. For multiple image references, verify against each reference's measurement separately. The report gives per-color ΔE and coverage drift with PASS/FAIL thresholds. If it fails, fix the offending colors and re-verify instead of asking the user to judge fidelity by eye.

If the user provides only content without DNA JSON, ask whether to:

Analyze a reference first (go to Phase 2)
Use a described style (extract DNA from description, then generate)

Phase Combinations

Users may invoke any combination:

Phase 1 only: "Show me the design structure/schema"
Phase 2 only: "Analyze this design" (with images/links)
Phase 2 → 3: "Analyze this design and build me a landing page in the same style"
Phase 1 → 2 → 3: Full pipeline
Phase 3 only: User already has DNA JSON

Detect which phase(s) are needed from context and execute accordingly.

# Design DNA

A 3-phase workflow for extracting, structuring, and applying design identity across three dimensions:

1. **Design System** — measurable tokens (color, typography, spacing, layout, shape, elevation, motion, components)
2. **Design Style** — qualitative perception (mood, visual language, composition, imagery, interaction feel, brand voice)
3. **Visual Effects** — special rendering (Canvas, WebGL, 3D, particles, shaders, scroll effects, cursor effects, SVG animations, glassmorphism, etc.)

## Phases

### Phase 1: Structure — Output the Schema

When the user asks for the structural dimensions or schema:

1. Read [references/schema.md](references/schema.md)
2. Present the full schema with field descriptions
3. Explain the three dimensions and their roles:
- **design_system**: What you can measure — exact hex values, pixel sizes, rem scales
- **design_style**: What you can feel — mood, personality, composition strategy
- **visual_effects**: What you can see but can't express in CSS alone — WebGL scenes, particle systems, shader distortions, scroll-driven animations
4. Ask if the user wants to customize or extend any dimensions

### Phase 2: Analyze — Extract DNA from References

When the user provides images, screenshots, or links representing a target design style:

1. Read [references/schema.md](references/schema.md) for the full field list
2. For each reference provided:
- If image/screenshot: **first run the deterministic color measurement** (see below), then analyze the remaining visual properties directly
- If URL: fetch and analyze the page's visual design
3. For every field in the schema, extract or infer a value from the references
4. When multiple references conflict, note the dominant pattern and mention variants
5. Output a complete Design DNA JSON — every field populated, no empty strings
6. After output, ask: "Want to adjust any values before using this for generation?"

**Analysis approach per dimension:**

#### Dimension 1: design_system
- **color**: Do not estimate hex values by eye — perceived colors drift toward familiar palette defaults (often by a ΔE of 10+). When the reference is an image file, measure instead. Resolve `SKILL_ROOT` to the absolute directory containing this `SKILL.md`; never assume the current project directory contains the skill's `scripts/` folder. Use absolute paths for the reference and output, and keep one uniquely named measurement file per reference:
```bash
npm install --prefix "$SKILL_ROOT/scripts" --silent
node "$SKILL_ROOT/scripts/measure-colors.mjs" "$REFERENCE_IMAGE" > "$MEASUREMENT_JSON"
```
Use the measured hexes verbatim in the DNA JSON: map the `background` role to `surface.background`; map `text` to the end of `neutral.scale` that contrasts with the measured background and document that foreground use in `neutral.usage`; and map `accent` to `accent.hex`. Keep both the measured palette and its `measurement` configuration in `design_system.color.measured_palette` and `design_system.color.measurement` so verification can reuse the same clustering configuration. Coverage values are fractions from `0` to `1`. Only fall back to visual sampling when measurement is impossible (for example, a URL-only reference that cannot be screenshotted). Choose primary and secondary colors by semantic role, use accent for CTA emphasis, and order the neutral scale from lightest to darkest regardless of theme.
- **typography**: Identify font families by visual characteristics (geometric, humanist, serif class). Estimate scale ratios from heading/body size relationships.
- **spacing**: Assess density by element proximity. Measure rhythm by section gap consistency.
- **layout**: Identify grid by content alignment patterns. Note max-width, column count, asymmetry.
- **shape**: Measure border-radius by comparing to element height. Note border and divider presence.
- **elevation**: Classify shadow softness, spread, and layering approach.
- **motion**: If observable (video/interactive), note easing curves and duration feel.

#### Dimension 2: design_style
- Synthesize holistic impressions — mood, personality, composition strategy
- Compare against genre archetypes (SaaS, editorial, brutalist, etc.)
- Note ornamentation level and whitespace philosophy

#### Dimension 3: visual_effects
- **From code**: Scan for `<canvas>`, WebGL contexts, Three.js/Pixi.js imports, GSAP/Lottie usage, custom shaders, IntersectionObserver scroll triggers, SVG `<animate>` elements
- **From screenshots**: Describe visible effects that go beyond standard CSS — glowing particles, 3D object renders, noise textures, gradient animations, parallax depth, cursor trails, text distortions, glassmorphic surfaces. Note these in `composite_notes` when exact implementation can't be determined.
- **From video/interaction demos**: Note scroll behaviors, hover distortions, transition choreography, loading sequences
- Set `enabled: false` for any effect category not present in the reference
- Rate `overview.effect_intensity` and `overview.performance_tier` based on what's observed

### Phase 3: Generate — Apply DNA to Content

When the user provides DNA JSON + content to design:

1. Read [references/generation-guide.md](references/generation-guide.md)
2. Parse the DNA JSON and extract all tokens across three dimensions
3. Build CSS custom properties from `design_system` values
4. Apply `design_style` qualitative fields to guide subjective design decisions
5. When the design needs assets or source materials, fetch them from the original source whenever possible. If the user provided a URL, retrieve the real asset from that URL instead of recreating, approximating, or substituting it.
6. Implement `visual_effects` using appropriate technologies:
- Lightweight effects → CSS animations, SVG, vanilla JS
- Medium effects → Canvas 2D, GSAP, Lottie
- Heavy effects → Three.js, custom GLSL shaders, Pixi.js
7. Generate the design output (default: self-contained HTML with inline CSS/JS)
8. Run quality checks from the generation guide
9. **Verify (when the DNA contains a measured palette)**: save the current Design DNA JSON if it is not already a file, screenshot the generated output, then score it against that DNA file. Resolve `SKILL_ROOT` from this `SKILL.md` and use absolute paths; do not assume a temporary file named `measured-colors.json` exists:
```bash
node "$SKILL_ROOT/scripts/verify.mjs" "$IMPLEMENTATION_SCREENSHOT" "$DESIGN_DNA_JSON"
```
A standalone measurement JSON may be used instead of the DNA file when that is the only persisted artifact. For multiple image references, verify against each reference's measurement separately. The report gives per-color ΔE and coverage drift with PASS/FAIL thresholds. If it fails, fix the offending colors and re-verify instead of asking the user to judge fidelity by eye.

**If the user provides only content without DNA JSON**, ask whether to:
- Analyze a reference first (go to Phase 2)
- Use a described style (extract DNA from description, then generate)

## Phase Combinations

Users may invoke any combination:
- **Phase 1 only**: "Show me the design structure/schema"
- **Phase 2 only**: "Analyze this design" (with images/links)
- **Phase 2 → 3**: "Analyze this design and build me a landing page in the same style"
- **Phase 1 → 2 → 3**: Full pipeline
- **Phase 3 only**: User already has DNA JSON

Detect which phase(s) are needed from context and execute accordingly.
