# Design System — voltagent.dev
> Extracted automatically by Clone Architect from https://voltagent.dev
> Date: 2026-05-30
> Viewport: Desktop 1440x900 + Mobile 390x844
> Every value in this file comes from real getComputedStyle() — no approximation.

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(5, 5, 7)` is the page background. Every component composits against this.
> - **Accent**: `#306cce` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 48px between major bands. Card padding: 48px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
>
> **Before generating UI**: import this DESIGN.md, scan §2 (Color Palette) + §4 (Components) + §10 (Agent Guide). Skip §11–12 unless extending.

## 1. Visual Theme & Atmosphere

voltagent.dev commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is an inky black surface (`#050507`) where elevation is communicated through subtle white-opacity gradations rather than traditional shadows — semi-transparent white borders act as the primary depth indicator, like wireframes etched in moonlight. 

Typography is anchored in **Inter**, deployed with OpenType features enabled globally (`"calt", "rlig"`). These aren't decorative — they're load-bearing: without them, the typeface reverts to its generic state and the design loses its specific texture. Headlines run at a remarkably light weight (400) — restraint over assertion, creating an editorial calm that invites reading rather than demanding it. Negative letter-spacing at display sizes (-0.65px at 60px) compresses headlines into engineered blocks, dense and authoritative. 

Body text reads in Light Gray (`#f2f2f2`) (contrast ratio 46.3:1, well above WCAG AA). **M Tricolor Blue** (`#306cce`) provides interactive distinction without visual aggression. Elevation is built from multi-layer shadow stacks — each level combines several blurred layers at varying offsets to simulate the way light actually falls on stacked surfaces, not the simulated drop-shadow of cheap interfaces. 
Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions. The site uses a variable font with SLNT axes, enabling precise weight/width control across the type hierarchy. 

**Key Characteristics:**
- Background: Pure Black (`#050507`)
- Primary typeface: IBM Plex Mono
- Primary text: Light Gray (`#e3e3e3`)
- Accent: M Tricolor Blue (`#306cce`)
- Display: 60px weight 400, letter-spacing -0.65px
- Shadow system: 14 distinct elevation levels
- Custom fonts loaded: IBM Plex Mono, IBM Plex Sans, Inter

### Full Font Size Scale

Sizes detected in the design (descending): `60px`, `36px`, `24px`, `20px`, `18px`, `16px`, `14px`, `13.33px`, `13px`, `12px`, `11px`

> 5 size(s) detected outside the sampled hierarchy (36px, 24px, 20px, 12px, 11px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles.

### OpenType & Variable Font Features

The typography uses these OpenType features intentionally — this is a sophisticated type system, not a default fallback:

- **contextual alternates** (`calt`) — connections between letters refined contextually

**Clone instruction:** Enable these in your CSS:
```css
body {
  font-feature-settings: "calt", "rlig";
}
```

**Variable font axes:**
- SLNT axis

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **FooterLink**:
  - **hover:** text #9ca3af → #9aa3ae

*State transitions extracted via Playwright simulation — exact values in the YAML matrix below.*

```yaml
component-behaviors:
  button:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 217, 146)"
  link:
    default:
      bg: "rgb(36, 37, 38)"
      fg: "rgb(245, 246, 247)"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(16, 185, 129)"
  footerLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(156, 163, 175)"
    hover:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(154, 163, 174)"
```

**Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand.


## 4c. Component Vocabulary (Closed System)

*This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.*

### Buttons
- **7 shape(s)** in this system: `Ghost`, `Outline`, `Dark / Solid`, `Ghost`, `Dark / Solid`
- **DO NOT introduce new buttons variants** without justification

### Navigation
- **1 shape(s)** in this system: `Main Nav`
- **DO NOT introduce new navigation variants** without justification

### Code Blocks
- **1 shape(s)** in this system: `Inline Code / Pre`
- **DO NOT introduce new code blocks variants** without justification

## 5. Layout Principles

### Layout Type
**top-nav + content**

### Grid
Single column, centered content

| Xs | 4px | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 8px | Cards, containers |
| Lg | 8px | Large rounded elements, pill segments |
| Xl | 8px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Navigation | `none` |
| Code Blocks | `0px` |
| Page Body | `0px` |

**Shape Personality**: Sharp & Angular — No rounding. Precise, editorial, enterprise feel.

**Full Radius Spectrum**: 0px, 2px, 4px, 6px, 6.4px, 8px, full/pill (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

*Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.*

| Name | Value | Use case |
|------|-------|----------|
| **hero** | `64px` | Top/bottom of full-bleed hero sections |
| **section** | `32px` | Between major bands (color change, content shift) |
| **subsection** | `48px` | Within a section, between content groups |
| **card** | `16px` | Card padding, list-item spacing |
| **compact** | `8px` | Form fields, tight clusters, badge padding |
| **micro** | `7px` | Icon-text gap, tag inner padding |

**Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.).

## 5c. Widget & Structure Library

Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values).

**4/8 structural patterns detected.**

### Hero Pattern

- **Composition:** split-left-text — Split layout, text-left/media-right — heading + body in left column, image/illustration in right column. Common for product showcases.
- **Viewport coverage:** 466px tall (not full-viewport)
- **Heading:** "AI Agent EngineeringPlatform" — 60px left-aligned
- **Media:** present, positioned right
- **CTAs:** 2 (primary: "Get Started")
- **Clone instruction:** Reproduce the **split-left-text** layout. Use the heading font-size token at the documented size. Place media right of text.

### Navigation Pattern

- **Position:** sticky (stays visible during scroll)
- **Layout:** logo-left-links-left — Logo and links both on the left (CTAs typically right)
- **Height:** 64px
- **Logo:** ✓ present
- **Nav links:** 4 primary items
- **CTAs in nav:** 2
- **Clone instruction:** Build a sticky logo left links left navigation. Reserve 2 slots for primary CTAs.

### Card Grid Pattern

- **Card count:** 8 cards detected
- **Columns (desktop):** 3-up grid
- **Card dimensions:** 544×451px (aspect 1.21:1)
- **Gap:** 0px between cards
- **Content:** ✗ no image + icon
- **Clone instruction:** Build a 3-column grid (desktop) with cards at ~1.21:1 aspect ratio. Text/icon-only cards (no photography).

### Footer Pattern

- **Columns:** 1
- **Links:** 17 total
- **Height:** 280px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~17 links per column, social media links, and a copyright line.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Inset (Level 1) | <br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0.7) 0px 20px 60px 0px`,<br>`rgba(148, 163, 184, 0.1) 0px 0px 0px 1px inset` | Buttons, pressed-state elements |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 217, 146, 0.3) 0px 0px 30px 0px` | Cards, elevated surfaces |
| Layered (Level 3) | <br>`rgba(0, 0, 0, 0.1) 0px 1px 2px 0px` | Cards, elevated surfaces |
| Layered (Level 4) | <br>`rgba(47, 214, 161, 0.4) 0px 0px 15px 3px`,<br>`rgba(47, 214, 161, 0.15) 0px 0px 30px 6px` | Cards, elevated surfaces |

**Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation.

## 7. Motion & Interaction

### Easing System

| CSS Variable | Curve | Semantic Name |

- **Animation Library**: 27 unique animations (27 total including variants)

> This design moves with deliberate & calm timing using custom cubic-bezier curves, creating a UI that feels calm and controlled.

## 8. Do's and Don'ts

### Do
- Use dark background (`#050507`) as the foundation — this is a dark-mode-native design
- Use Inter as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-0.65px) at display sizes for compressed, editorial headlines
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
- Use M Tricolor Blue (`#306cce`) as the primary accent — it's the brand's signature interactive color
- Use 6px border-radius on buttons — the standard corner rounding for interactive elements
- Keep navigation sticky to the top — the design uses a persistent navigation pattern
- Maintain nav height at 64px — consistent vertical space for the navigation bar
- Build the hero as a split layout with media on the left — text and visual share equal weight
- Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
- Make the navigation sticky — it stays visible during scroll, signaling content depth
- Each card uses an icon (not photo) — the visual language is illustrative, not photographic
- Use a 3-column grid on desktop — density matters for this content type

### Don't
- Don't use light backgrounds — the dark canvas is the native medium
- Don't substitute with generic sans-serif or serif — the custom font carries the brand
- Don't increase letter-spacing on headings — the type is designed to run tight at scale
- Don't invent new shadow values — use only the extracted shadow levels
- Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements
- Don't introduce additional saturated accent colors — the palette is intentionally controlled
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence


## 7b. Enforceable Brand Rules

*Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.*

```yaml
rules:
  - id: brand-canvas-001
    type: do
    rule: "Always use the page background `rgb(5, 5, 7)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(5, 5, 7)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `#306cce` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#306cce\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 360px | Single column, compact spacing |
| Mobile Large | 640px | Expanded mobile layout |
| Mobile Large | 720px | Expanded mobile layout |
| Mobile Large | 767px | Expanded mobile layout |
| Tablet | 996px | Multi-column grids begin |
| Desktop | 1100px | Full feature layout |
| Desktop | 1270px | Full feature layout |
| Large Desktop | 1440px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `60px` | `36px` |
| heading | line-height | `60px` | `40px` |
| button | width | `auto` | `46px` |

### Collapsing Strategy
- Headlines: 60px → 36px on mobile
- Navigation: horizontal links → hamburger menu on mobile
- Cards: multi-column → stacked vertical on mobile
- Footer: multi-column → stacked single column on mobile

### Touch Targets
- Buttons: 8px padding
- Navigation: adequate spacing between items
- Interactive elements: minimum 44px touch target recommended

### Collapsing Narrative

How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions):

- **Hero collapses split-left-text → centered** — the side-by-side layout stacks vertically, with media moving above the text.
- **Navigation collapses to hamburger** — 4 links visible on desktop, 1 on mobile (the rest hide behind a menu toggle).
- **Nav CTAs reduced** on mobile (2 → 1) — the design prioritizes content over conversion buttons at small sizes.
- **Card grid: 3-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.

## 9b. Visual Tone & Photography

**Tone:** Illustration-driven

The site relies primarily on illustrations, vector art, and decorative SVG elements rather than photography. Use commissioned illustrations, icon sets, or generated graphics for clones — stock photos will feel off-brand.

**Canonical Brand Image (OG):**
- https://voltagent.dev/img/social4.png
  *This is the image shown when the site is shared on social media — represents the brand visual essence.*

**Hero Image (above-fold dominant visual):**
- Aspect: 1.28:1 (landscape)
- Rendered size: 767×600px
- Alt text: "framework preview"
- *Use this aspect ratio + composition for your clone's hero — mimicking the proportion preserves the visual hierarchy.*

**Aspect Ratio Distribution:**
- Landscape (1.15–2.3): 1 (100%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 0 (0%)

**Media Format Mix:**
- PNG: 1 (logos, transparent UI elements, mockups)
- SVG: 23 (icons, illustrations, decorative geometry)

**Average rendered image size:** 767×600px
**Above-fold image count:** 0 / 1

**Decorative Patterns Detected:**
- 1 radial gradient — circular color blooms used for spotlight/glow effects
- 23 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents
- **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic

**Clone instruction for decorative work:** Decorative SVG accents are part of the brand — generate or source blob/illustration shapes to scatter behind content.

**Imagery Guidance for clones:**
- Use vector illustration as the primary visual language — photos will read as off-brand.
- Maintain consistent illustration style (line weight, color palette) across the site.

## 10. Agent Prompt Guide

### Quick Reference
- Background: Pure Black (`#050507`)
- Primary text: Light Gray (`#f2f2f2`)
- Accent: M Tricolor Blue (`#306cce`)
- Border: Slate (`#4b5563`)
- Font: Inter
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Pure Black background (#050507). Headline at 60px Inter weight 400, line-height 1, letter-spacing -0.65px, color #f2f2f2."
- "Create the primary CTA button: `#306cce` background, `#00d992` text, 9999px border-radius, 8px padding, 700 weight, Inter font."
- "Build navigation: sticky on `#050507`. Inter 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Pure Black (`#050507`) — every component is composited against this exact base.
2. **Typography**: All type in Inter, weight range 300–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: M Tricolor Blue (`#306cce`) is the sole interactive color. On hover → #2554a0 (`#2554a0`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.08,0.52,0.52,1)`. Timing: 200ms for micro-interactions, 200ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `6px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (7px–32px). All padding, margin, and gap values are multiples from this scale — no magic numbers.
7. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent.

## 11. CSS Design Tokens Raw Export

*Copy-paste ready `:root {}` block — all values extracted directly from the live site.*

```css
/* Colors */
:root {
  --ca-canvas: #050507;
  --ca-surface-1: #262626;
  --ca-ink: #f2f2f2;

```


## 13. Page Structure Skeleton

*The actual layout the source site uses. Reproduce these sections in order to match the site structure.*

```yaml
page-skeleton:
  - section: unknown
    tag: div
    height: 9415px
    width: full-bleed
    layout: flex-column justify=normal
    children: 4
    bg: "rgb(5, 5, 7)"
  - section: main-content
    tag: main
    classes: ["flex-1", "relative", "overflow-hidden", "bg-[#050507]"]
    height: 9071px
    width: full-bleed
    layout: block
    children: 5
    bg: "rgb(5, 5, 7)"
  - section: unknown
    tag: div
    classes: ["main-wrapper", "mainWrapper_z2l0"]
    height: 9071px
    width: full-bleed
    layout: flex-column justify=normal
    children: 1
    bg: "rgb(5, 5, 7)"
  - section: section-3
    tag: section
    classes: ["feature-showcase", "relative", "z-10", "px-4"]
    height: 699px
    width: full-bleed
    layout: block
    children: 1
    padding: "0px 24px"
  - section: section-4
    tag: section
    classes: ["relative", "w-full", "overflow-hidden"]
    height: 584px
    width: full-bleed
    layout: block
    children: 2
  - section: section-5
    tag: section
    classes: ["relative", "w-full", "overflow-hidden", "z-10"]
    height: 589px
    width: full-bleed
    layout: block
    children: 2
  - section: footer
    tag: footer
    classes: ["text-[#dcdcdc]", "font-['Inter']", "py-8", "md:py-12"]
    height: 280px
    width: full-bleed
    layout: block
    children: 1
    padding: "48px 0px"
```

**Agent rule**: rebuild sections in this order (sorted by vertical position). Match the layout primitive (grid N-col / flex direction / block).


## 14. Copy Library (Real Content from Source)

*Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.*

```yaml
copy:
  section-headings:
    - "The end-to-end"
    - "THE PLATFORM"
    - "USED AND TESTED BY DEVELOPERS AT"
    - "Complete toolkit for enterprise level AI agents"
  ctas:
    - "Get Started"
    - "$
npm create voltagent-app@latest"
    - "Framework"
    - "Observability"
  navigation:
    - "voltagent"
    - "Documentation"
    - "Pricing"
    - "Thank you!
9.2K"
    - "Try VoltOps"
  footer-links:
    - "Privacy Policy"
    - "Getting Started"
```

**Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording.


## 15. Asset Inventory (Image Roles & Ratios)

*Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.*

```yaml
assets:
  thumbnail:
    count: 13
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "onekr-billy avatar"
      - "sharkoil avatar"
      - "jjj124 avatar"
```

**Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`.


## 16. Component HTML Templates

*Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.*

### Button (primary action)
```html
<button class="btn btn-primary">
  Get Started
</button>
```
_Source pattern detected: padding `12px 16px` · radius `6px` · weight `700`_

**Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling.


## 12. Known Extraction Gaps

*Auto-detected limitations of this extraction — understand before building:*

- **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass.
- **6 parasitic shadow(s) detected** — colored box-shadows (not near-black) found in allShadows. These likely originate from browser extensions or third-party injected widgets (e.g. Grammarly, chat overlays), not from the site's own design system. Discard them when building.
