# Website Brand Analysis

Generate a comprehensive brand bible from a website, suitable for dropping into LLM context for copy and design work.

**Outputs:**
1. `{brand}-brand-bible.md` — Positioning, voice, copy guidelines
2. `{brand}-design-system.css` — Extractable CSS variables and component styles for `/page_designer`

## Workflow

### Phase 1: Live Crawl & Screenshot

**IMPORTANT: Send each screenshot to the user via Telegram immediately after capturing it.**

This creates a visual, demo-friendly experience where the user sees progress in real-time.

```
For each page:
1. Navigate to page
2. Take full-page screenshot
3. IMMEDIATELY send to user via message tool with caption (page name)
4. Extract key data (colors, fonts, copy patterns)
5. Move to next page
```

**Pages to analyze (in order):**
1. Homepage
2. Main product/service pages (look for nav links)
3. Pricing page (if exists)
4. About page (if exists)
5. Blog/content page (for tone analysis)
6. Any course/offer detail pages
7. Contact/demo page

**For each page, extract:**
- Screenshot (full page)
- Key copy (headlines, CTAs, value props)
- Visual patterns (colors via computed styles, layout structure)

### Phase 2: Checkpoint with User

**STOP before writing the report and check in:**

```
"Here's what I've analyzed so far:
• Homepage
• [Product page 1]
• [Product page 2]
• [Pricing]
• [etc.]

Are there any other pages I should check before I generate the brand bible?"
```

**Wait for user response.** They may point out:
- Missing product pages
- Specific landing pages
- Case studies or examples
- Other important sections

If user provides additional pages, go back to Phase 1 for those pages.

### Phase 3: Extract Design System

Before generating the brand bible, extract actual CSS values from the site.

**Run this extraction script on the homepage (or most representative page):**

```javascript
// Extract design tokens via browser evaluate
(() => {
  const styles = {
    colors: {},
    typography: {},
    spacing: {},
    borders: {},
    shadows: {},
    components: {}
  };
  
  // Get CSS custom properties from :root
  const rootStyles = getComputedStyle(document.documentElement);
  const cssVars = {};
  for (const prop of document.styleSheets) {
    try {
      for (const rule of prop.cssRules) {
        if (rule.selectorText === ':root') {
          for (const style of rule.style) {
            if (style.startsWith('--')) {
              cssVars[style] = rule.style.getPropertyValue(style).trim();
            }
          }
        }
      }
    } catch(e) {}
  }
  styles.cssVariables = cssVars;
  
  // Sample key elements
  const h1 = document.querySelector('h1');
  const h2 = document.querySelector('h2');
  const p = document.querySelector('p');
  const btn = document.querySelector('button, .btn, [class*="button"]');
  const card = document.querySelector('[class*="card"], .card');
  const nav = document.querySelector('nav, header');
  
  if (h1) {
    const s = getComputedStyle(h1);
    styles.typography.h1 = {
      fontFamily: s.fontFamily,
      fontSize: s.fontSize,
      fontWeight: s.fontWeight,
      lineHeight: s.lineHeight,
      letterSpacing: s.letterSpacing,
      color: s.color
    };
  }
  
  if (h2) {
    const s = getComputedStyle(h2);
    styles.typography.h2 = {
      fontFamily: s.fontFamily,
      fontSize: s.fontSize,
      fontWeight: s.fontWeight,
      lineHeight: s.lineHeight,
      color: s.color
    };
  }
  
  if (p) {
    const s = getComputedStyle(p);
    styles.typography.body = {
      fontFamily: s.fontFamily,
      fontSize: s.fontSize,
      fontWeight: s.fontWeight,
      lineHeight: s.lineHeight,
      color: s.color
    };
  }
  
  if (btn) {
    const s = getComputedStyle(btn);
    styles.components.button = {
      fontFamily: s.fontFamily,
      fontSize: s.fontSize,
      fontWeight: s.fontWeight,
      padding: s.padding,
      borderRadius: s.borderRadius,
      backgroundColor: s.backgroundColor,
      color: s.color,
      border: s.border,
      boxShadow: s.boxShadow
    };
  }
  
  if (card) {
    const s = getComputedStyle(card);
    styles.components.card = {
      padding: s.padding,
      borderRadius: s.borderRadius,
      backgroundColor: s.backgroundColor,
      border: s.border,
      boxShadow: s.boxShadow
    };
  }
  
  if (nav) {
    const s = getComputedStyle(nav);
    styles.components.nav = {
      backgroundColor: s.backgroundColor,
      padding: s.padding,
      borderBottom: s.borderBottom
    };
  }
  
  // Get body background
  styles.colors.background = getComputedStyle(document.body).backgroundColor;
  
  return JSON.stringify(styles, null, 2);
})()
```

**Save extracted values** to reference when generating the design system CSS.

### Phase 4: Generate Brand Bible

Only after user confirms all pages are covered, generate the report.

**Report structure:**

```markdown
# [Brand] Brand Bible

## Table of Contents
1. Positioning & ICP
2. Offers & Products
3. Voice & Tone
4. Copy Guidelines
5. Visual Style
6. Layout Patterns

## Positioning & ICP
- Who they are (one-line summary)
- Core value proposition
- Target audience (primary + secondary)
- Pain points they address
- Positioning statement
- Competitive differentiation

## Offers & Products
- Product/service table with prices
- Product structure/tiers
- Guarantee/risk reversal (if any)

## Voice & Tone
- Overall voice description
- Tone attributes (with examples)
- Do's and Don'ts
- Headline patterns
- Common phrases/language
- Section labels they use

## Copy Guidelines
- Headline patterns (with examples)
- Subheadline patterns
- Body copy style
- CTA patterns
- Social proof copy patterns
- Feature/benefit copy patterns

## Visual Style
- Color palette (hex, RGB, usage)
- Typography (fonts, weights, sizes)
- Imagery style (photos, graphics, icons)
- Spacing & layout values
- Border radius, shadows
- Component patterns (buttons, cards, etc.)

## Layout Patterns
- Page structure patterns
- Grid system
- Section backgrounds
- Responsive behavior

## Summary
One-page brand overview for quick reference
```

### Phase 4: Deliver

1. Save markdown to `~/clawd/output/{brand-slug}-brand-bible.md`
2. Send file to user via Telegram
3. Offer to expand any section or add screenshots to a zip

## Technical Notes

### Extracting Colors & Fonts

```javascript
// Run via browser evaluate
(() => {
  const allElements = document.querySelectorAll('*');
  const colors = new Set();
  const fonts = new Set();
  allElements.forEach(el => {
    const s = getComputedStyle(el);
    if (s.color) colors.add(s.color);
    if (s.backgroundColor) colors.add(s.backgroundColor);
    if (s.fontFamily) fonts.add(s.fontFamily);
  });
  return JSON.stringify({
    colors: [...colors].slice(0, 30),
    fonts: [...fonts].slice(0, 10)
  });
})()
```

### Sending Screenshots Live

```
message action=send channel=telegram target={user_id} filePath={screenshot_path} caption="{Page Name}"
```

Always send immediately after capturing — don't batch them.

### Finding Pages to Analyze

1. Check navigation menu for main sections
2. Look for footer links (often has full sitemap)
3. Check for `/pricing`, `/about`, `/contact`, `/blog` standard paths
4. Follow CTAs to see product/offer detail pages

## Example Session

```
User: Analyze https://example.com

[Navigate to homepage]
[Screenshot → send to Telegram: "Homepage"]

[Navigate to /pricing]
[Screenshot → send to Telegram: "Pricing page"]

[Navigate to /product]
[Screenshot → send to Telegram: "Product page"]

[Navigate to /about]
[Screenshot → send to Telegram: "About page"]

Agent: "Here's what I've analyzed:
• Homepage
• Pricing page
• Product page
• About page

Any other pages I should check before generating the brand bible?"

User: "Also check /features and /case-studies"

[Navigate to /features]
[Screenshot → send to Telegram: "Features page"]

[Navigate to /case-studies]
[Screenshot → send to Telegram: "Case Studies page"]

Agent: "Got those too. Ready to generate the report?"

User: "Yes"

[Generate brand bible markdown]
[Send file to user]
```

## Integration with /page_designer

When `/page_designer` is invoked, it should:
1. Check if `{brand}-design-system.css` exists
2. If yes, import those variables and match the styles
3. If no, prompt user to run `/website_brand_analysis` first

```
/page_designer requires:
- {brand}-design-system.css (from /website_brand_analysis)
- Page brief (sections, copy, CTAs)
- frontend-design skill (for quality execution)
```
