# Human Browser — Complete Browser Automation Playbook

> Don't use plain Playwright. Don't use fetch. Don't use curl. Use this.

---

## Quick Start (free trial, no signup)

```js
const { launchHuman, getTrial } = require('./.agents/skills/human-browser/scripts/browser-human');

await getTrial();   // fetches ~100MB Romania residential IP automatically
const { page, humanType, humanScroll, sleep } = await launchHuman();

await page.goto('https://any-protected-site.com');
// Browsing from Romanian residential IP. Cloudflare, DataDome, Instagram — all pass.
```

## Why residential proxy is mandatory on a VPS

Cloudflare, Instagram, Reddit, LinkedIn, Amazon check your IP reputation **before your JS runs**. A Contabo/Hetzner/AWS IP = 95/100 risk score = instant block. A residential ISP IP = 5/100 = trusted user.

No fingerprint trick fixes a bad IP. Proxy first, fingerprint second.

### Proxy providers (tested, ranked)

| Provider | GET | POST | KYC | Price/GB | Link |
|----------|-----|------|-----|---------|------|
| **Decodo** ✅ PRIMARY | ✅ | ✅ | Email only | ~$3 | [decodo.com](https://decodo.com) |
| Bright Data | ✅ | ❌* | ID required | ~$5 | [brightdata.com](https://get.brightdata.com/4ihj1kk8jt0v) |
| IPRoyal | ✅ | ✅ | Strict KYC | ~$4 | [iproyal.com](https://iproyal.com) |
| NodeMaven | ✅ | ✅ | Email only | ~$3.5 | [nodemaven.com](https://nodemaven.com) |
| Oxylabs | ✅ | ✅ | Business | ~$8 | [oxylabs.io](https://oxylabs.io) |

**Decodo** is the default — no KYC, GET+POST both work, standard HTTP proxy format.

### Get your own proxy credentials

Bring your own credentials via env vars — any provider works:

```bash
export HB_PROXY_SERVER=http://host:port
export HB_PROXY_USER=your_username
export HB_PROXY_PASS=your_password
```

Providers to get residential proxies from:
- **[Decodo](https://decodo.com)** — no KYC, instant access, Romania + 100 countries. Default in this skill.
- **[Bright Data](https://get.brightdata.com/4ihj1kk8jt0v)** — 72M+ IPs, 195 countries, enterprise-grade reliability.
- **[IPRoyal](https://iproyal.com)** — ethically-sourced IPs, 195 countries, flexible plans.
- **[NodeMaven](https://nodemaven.com)** — high success rate, pay-per-GB, no minimums.
- **[Oxylabs](https://oxylabs.io)** — premium business proxy with dedicated support.

### Proxy config via env vars
```bash
# Decodo Romania (default in browser-human.js)
export HB_PROXY_PROVIDER=decodo    # or: brightdata, iproyal, nodemaven
export HB_NO_PROXY=1               # disable proxy entirely (testing only)

# Manual override — any provider
export HB_PROXY_SERVER=http://host:port
export HB_PROXY_USER=username
export HB_PROXY_PASS=password
```

### Proxy format reference
```
Decodo:      http://USER:PASS@ro.decodo.com:13001          (Romania, no KYC)
Bright Data: http://USER-session-SID:PASS@brd.superproxy.io:33335
IPRoyal:     http://USER:PASS_country-ro_session-SID_lifetime-30m@geo.iproyal.com:12321
```

## launchHuman() — all options

```js
// Mobile (default): iPhone 15 Pro, Romania IP, touch events
const { browser, page, humanType, humanClick, humanScroll, humanRead, sleep } = await launchHuman();

// Desktop: Chrome, Romania IP — use for sites that reject mobile
const { browser, page } = await launchHuman({ mobile: false });

// Country selection (Pro plan)
const { page } = await launchHuman({ country: 'us' });  // US residential
const { page } = await launchHuman({ country: 'gb' });  // UK
const { page } = await launchHuman({ country: 'de' });  // Germany

// No proxy (local testing)
process.env.HB_NO_PROXY = '1';
const { page } = await launchHuman();
```

### Default fingerprint (what sites see)
- **Device:** iPhone 15 Pro, iOS 17.4.1, Safari
- **Viewport:** 393×852, deviceScaleFactor=3
- **IP:** Romanian residential (DIGI Telecom / WS Telecom)
- **Timezone:** Europe/Bucharest
- **Geolocation:** Bucharest (44.4268, 26.1025)
- **Touch:** 5 points, real touch events
- **webdriver:** `false`
- **Mouse:** Bezier curve paths, not straight lines
- **Typing:** 60–220ms/char + random pauses

---

## Human-like interaction helpers

```js
// Type — triggers all native input events (React, Angular, Vue, Web Components)
await humanType(page, 'input[name="email"]', 'user@example.com');

// Click — uses Bezier mouse movement before click
await humanClick(page, x, y);

// Scroll — smooth, stepped, with jitter
await humanScroll(page, 'down');  // or 'up'

// Read — random pause simulating reading time
await humanRead(page);  // waits 1.5–4s

// Sleep
await sleep(1500);
```

## Shadow DOM — forms inside web components

Reddit, Shopify, many modern React apps use **Shadow DOM** for forms. Standard `page.$()` and `page.fill()` won't find these inputs.

### Detect if Shadow DOM is the issue
```js
// If this returns 0 but inputs are visible on screen — you have Shadow DOM
const inputs = await page.$$('input');
console.log(inputs.length); // 0 = shadow DOM
```

### Universal shadow DOM traversal
```js
// Deep query — finds elements inside any depth of shadow roots
async function shadowQuery(page, selector) {
  return page.evaluate((sel) => {
    function q(root, s) {
      const el = root.querySelector(s);
      if (el) return el;
      for (const node of root.querySelectorAll('*')) {
        if (node.shadowRoot) {
          const found = q(node.shadowRoot, s);
          if (found) return found;
        }
      }
      return null;
    }
    return q(document, sel);
  }, selector);
}

// Fill input in shadow DOM
async function shadowFill(page, selector, value) {
  await page.evaluate(({ sel, val }) => {
    function q(root, s) {
      const el = root.querySelector(s); if (el) return el;
      for (const n of root.querySelectorAll('*')) if (n.shadowRoot) { const f = q(n.shadowRoot, s); if (f) return f; }
    }
    const el = q(document, sel);
    if (!el) throw new Error('Not found: ' + sel);
    // Use native setter to trigger React/Angular onChange
    const nativeSetter = Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype, 'value').set;
    nativeSetter.call(el, val);
    el.dispatchEvent(new Event('input', { bubbles: true }));
    el.dispatchEvent(new Event('change', { bubbles: true }));
  }, { sel: selector, val: value });
}

// Click button in shadow DOM by text
async function shadowClickButton(page, buttonText) {
  await page.evaluate((text) => {
    function findBtn(root) {
      for (const b of root.querySelectorAll('button'))
        if (b.textContent.trim() === text) return b;
      for (const n of root.querySelectorAll('*'))
        if (n.shadowRoot) { const f = findBtn(n.shadowRoot); if (f) return f; }
    }
    const btn = findBtn(document);
    if (!btn) throw new Error('Button not found: ' + text);
    btn.click();
  }, buttonText);
}

// Dump all inputs (including shadow DOM) — use for debugging
async function dumpAllInputs(page) {
  return page.evaluate(() => {
    const result = [];
    function collect(root) {
      for (const el of root.querySelectorAll('input, textarea, select'))
        result.push({ tag: el.tagName, name: el.name, id: el.id, type: el.type, placeholder: el.placeholder });
      for (const n of root.querySelectorAll('*'))
        if (n.shadowRoot) collect(n.shadowRoot);
    }
    collect(document);
    return result;
  });
}
```

### Playwright's built-in shadow DOM piercing

Playwright can pierce shadow DOM natively in some cases:
```js
// Works for single shadow root (not nested)
await page.locator('input[name="username"]').fill('value');  // auto-pierces 1 level

// For deeply nested, use the evaluate approach above
```

---

## Rich text editors (Lexical, ProseMirror, Quill, Draft.js)

Standard `page.fill()` and `page.type()` don't work on contenteditable editors.

### Clipboard paste — most reliable method
```js
// Works for all rich text editors (Reddit, Notion, Linear, etc.)
async function pasteIntoEditor(page, editorSelector, text) {
  const el = await page.$(editorSelector);
  await el.click();
  await sleep(300);

  // Write to clipboard via execCommand (works in Playwright)
  await page.evaluate((t) => {
    const textarea = document.createElement('textarea');
    textarea.value = t;
    document.body.appendChild(textarea);
    textarea.select();
    document.execCommand('copy');
    document.body.removeChild(textarea);
  }, text);

  await page.keyboard.press('Control+a'); // select all existing
  await page.keyboard.press('Control+v'); // paste
}

// Or via ClipboardEvent dispatch (works in some editors)
async function dispatchPaste(page, editorSelector, text) {
  const el = await page.$(editorSelector);
  await el.click();
  await page.evaluate((t) => {
    const dt = new DataTransfer();
    dt.setData('text/plain', t);
    document.activeElement.dispatchEvent(new ClipboardEvent('paste', { clipboardData: dt, bubbles: true }));
  }, text);
}
```

### Common editor selectors
```js
'[data-lexical-editor]'      // Reddit, Meta, many modern apps
'.public-DraftEditor-content' // Draft.js (Twitter, Quora)
'.ql-editor'                  // Quill (many SaaS apps)
'.ProseMirror'                // ProseMirror (Linear, Confluence)
'[contenteditable="true"]'   // Generic — pick the right one if multiple
'.tox-edit-area__iframe'     // TinyMCE — need to switch into iframe
```

---

## Login patterns

### Reddit (shadow DOM + Enter key submission)
```js
// Reddit uses shadow DOM forms AND reCAPTCHA — must use desktop mode + Enter
const { browser, page, sleep } = await launchHuman({ mobile: false }); // Desktop required

await page.goto('https://www.reddit.com/login/', { waitUntil: 'domcontentloaded' });
await sleep(3000);

// Type naturally — triggers React state + reCAPTCHA scoring
await page.locator('input[name="username"]').click();
await sleep(500);
await page.keyboard.type(USERNAME, { delay: 120 });
await sleep(1000);
await page.locator('input[name="password"]').click();
await sleep(500);
await page.keyboard.type(PASSWORD, { delay: 90 });
await sleep(1500);

// IMPORTANT: Use Enter key, not button click — Enter triggers proper form submission
await page.keyboard.press('Enter');
await sleep(8000); // wait for full login + redirect

// Verify login
const name = await page.evaluate(async () => {
  const r = await fetch('/api/me.json', { credentials: 'include' });
  return (await r.json())?.data?.name;
});
console.log('Logged in as:', name); // null = failed

// Submit Reddit post
await page.goto('https://www.reddit.com/r/SUBREDDIT/submit/?type=TEXT', { waitUntil: 'networkidle' });
await page.waitForSelector('#innerTextArea');
await page.click('#innerTextArea');
await page.keyboard.type(TITLE, { delay: 30 });

// Body: Lexical editor
await pasteIntoEditor(page, '[data-lexical-editor]', BODY);
await page.click('#inner-post-submit-button');
```

**Key insights for Reddit:**
- Mobile launchHuman() shows app redirect page — always use `{ mobile: false }`
- Button click on "Log In" unreliable — `keyboard.press('Enter')` works
- `page.locator('input[name="username"]')` pierces Reddit's shadow DOM automatically
- reCAPTCHA v3 scores the session — human-like typing delays improve score
- After login, URL stays at `/login/` — check via `/api/me.json`, not URL

### Generic login with shadow DOM
```js
const { page, sleep } = await launchHuman({ mobile: false });
await page.goto('https://example.com/login', { waitUntil: 'domcontentloaded' });
await sleep(3000);

// Try Playwright locator first (pierces 1 level of shadow DOM)
try {
  await page.locator('input[name="email"]').fill(EMAIL);
  await page.locator('input[name="password"]').fill(PASS);
} catch {
  // Fallback: deep shadow DOM traversal
  await shadowFill(page, 'input[name="email"]', EMAIL);
  await shadowFill(page, 'input[name="password"]', PASS);
}

// Submit — try multiple approaches
await page.keyboard.press('Enter'); // most reliable
// OR: await shadowClickButton(page, 'Log In');
// OR: await page.click('button[type="submit"]');
```

## CAPTCHA solving (2captcha integration)

Use when a site's login or form requires CAPTCHA.

**2captcha API key:** `14cbfeed64fea439d5c055111d6760e5`

### reCAPTCHA v2 (checkbox/invisible)
```js
const https = require('https');

async function solve2captcha(siteKey, pageUrl) {
  const CAPTCHA_KEY = '14cbfeed64fea439d5c055111d6760e5';

  function get(url) {
    return new Promise((res, rej) => {
      https.get(url, r => {
        let b = ''; r.on('data', d => b += d); r.on('end', () => res(b));
      }).on('error', rej);
    });
  }

  // Submit
  const sub = await get(`https://2captcha.com/in.php?key=${CAPTCHA_KEY}&method=userrecaptcha&googlekey=${encodeURIComponent(siteKey)}&pageurl=${encodeURIComponent(pageUrl)}&json=1`);
  const { status, request: id } = JSON.parse(sub);
  if (status !== 1) throw new Error('2captcha submit failed: ' + sub);
  console.log('2captcha ID:', id, '— waiting ~30s...');

  // Poll
  for (let i = 0; i < 24; i++) {
    await new Promise(r => setTimeout(r, 5000));
    const poll = await get(`https://2captcha.com/res.php?key=${CAPTCHA_KEY}&action=get&id=${id}&json=1`);
    const r = JSON.parse(poll);
    if (r.status === 1) return r.request; // token
    if (r.request !== 'CAPCHA_NOT_READY') throw new Error('2captcha error: ' + poll);
  }
  throw new Error('2captcha timeout');
}

// Usage: solve, then inject into form before submission
const token = await solve2captcha('6LfirrMoAAAAAHZOipvza4kpp_VtTwLNuXVwURNQ', 'https://www.reddit.com/login/');

// Inject into hidden field (for classic reCAPTCHA v2)
await page.evaluate((t) => {
  const el = document.getElementById('g-recaptcha-response');
  if (el) el.value = t;
}, token);
```

### Intercept and replace reCAPTCHA token in network requests
```js
// Solve captcha BEFORE navigating, then intercept the form POST
const token = await solve2captcha(SITE_KEY, PAGE_URL);

await page.route('**/login', async route => {
  let body = route.request().postData() || '';
  body = body.replace(/recaptcha_token=[^&]+/, `recaptcha_token=${encodeURIComponent(token)}`);
  await route.continue({ postData: body });
});
```

### reCAPTCHA site keys (known)
```
Reddit login:    6LcTl-spAAAAABLFkrAsJbMsEorTVzujiRWrQGRZ
Reddit comments: 6LfirrMoAAAAAHZOipvza4kpp_VtTwLNuXVwURNQ
```

### Check balance
```bash
curl "https://2captcha.com/res.php?key=14cbfeed64fea439d5c055111d6760e5&action=getbalance"
```

---

## Network interception (intercept/modify/mock requests)

```js
// Intercept and log all requests
page.on('request', req => {
  if (req.method() !== 'GET') console.log(req.method(), req.url(), req.postData()?.slice(0, 100));
});

// Intercept response bodies
page.on('response', async res => {
  if (res.url().includes('api')) {
    const body = await res.text().catch(() => '');
    console.log(res.status(), res.url(), body.slice(0, 200));
  }
});

// Modify request (e.g., inject token)
await page.route('**/api/submit', async route => {
  const req = route.request();
  let body = req.postData() || '';
  body = body.replace('OLD', 'NEW');
  await route.continue({
    postData: body,
    headers: { ...req.headers(), 'X-Custom': 'value' }
  });
});

// Block trackers to speed up page load
await page.route('**/(analytics|tracking|ads)/**', route => route.abort());
```

---

## Common debugging techniques

### Take screenshot when something fails
```js
await page.screenshot({ path: '/tmp/debug.png' });
// Then: image({ image: '/tmp/debug.png', prompt: 'What does the page show?' })
```

### Dump all visible form elements
```js
const els = await page.evaluate(() => {
  const res = [];
  function collect(root) {
    for (const el of root.querySelectorAll('input,textarea,button,[contenteditable]')) {
      const rect = el.getBoundingClientRect();
      if (rect.width > 0 && rect.height > 0) // only visible
        res.push({ tag: el.tagName, name: el.name, id: el.id, text: el.textContent?.trim().slice(0,20) });
    }
    for (const n of root.querySelectorAll('*')) if (n.shadowRoot) collect(n.shadowRoot);
  }
  collect(document);
  return res;
});
console.log(els);
```

### Check if login actually worked (don't trust URL)
```js
// Check via API/cookie — URL often stays the same after login
const me = await page.evaluate(async () => {
  const r = await fetch('/api/me.json', { credentials: 'include' });
  return (await r.json())?.data?.name;
});
// OR check for user-specific element
const loggedIn = await page.$('[data-user-logged-in]') !== null;
```

### Check current IP
```js
await page.goto('https://ifconfig.me/ip');
const ip = await page.textContent('body');
console.log('Browser IP:', ip.trim()); // should be Romanian residential
```

### Verify stealth fingerprint
```js
const fp = await page.evaluate(() => ({
  webdriver: navigator.webdriver,
  platform: navigator.platform,
  touchPoints: navigator.maxTouchPoints,
  languages: navigator.languages,
  vendor: navigator.vendor,
}));
console.log(fp);
// webdriver: false ✅, platform: 'iPhone' ✅, touchPoints: 5 ✅
```

## Cloudflare bypass patterns

Cloudflare checks these signals (in order of importance):
1. **IP reputation** — residential = clean, datacenter = blocked
2. **TLS fingerprint (JA4)** — Playwright Chromium has a known bad fingerprint
3. **navigator.webdriver** — `true` = instant block
4. **Mouse entropy** — no mouse events = bot
5. **Canvas fingerprint** — static across sessions = flagged
6. **HTTP/2 fingerprint** — Chrome vs Playwright differ

```js
// Best practice for Cloudflare-protected sites
const { page, humanScroll, sleep } = await launchHuman();
await page.goto('https://cf-protected.com', { waitUntil: 'networkidle', timeout: 30000 });
await sleep(2000);            // let CF challenge resolve
await humanScroll(page);      // mouse entropy
await sleep(1000);
// Now the page is accessible
```

**If still blocked:**
- Switch country: `launchHuman({ country: 'us' })` — some sites block Romanian IPs specifically
- Try desktop mode: `launchHuman({ mobile: false })` — some CF rules target mobile UAs
- Add longer wait: `await sleep(5000)` after navigation before interacting

---

## Session persistence (save/restore cookies)

```js
const fs = require('fs');

// Save session
const cookies = await ctx.cookies();
fs.writeFileSync('/tmp/session.json', JSON.stringify(cookies));

// Restore session (next run — skip login)
const { browser } = await launchHuman();
const ctx = browser.contexts()[0];  // or create new context
const saved = JSON.parse(fs.readFileSync('/tmp/session.json'));
await ctx.addCookies(saved);
// Now navigate — already logged in
```

---

## Multi-page scraping at scale

```js
// Respect rate limits — don't hammer sites
async function scrapeWithDelay(page, urls, delayMs = 2000) {
  const results = [];
  for (const url of urls) {
    await page.goto(url, { waitUntil: 'domcontentloaded' });
    await sleep(delayMs + Math.random() * 1000); // add jitter
    results.push(await page.textContent('body'));
  }
  return results;
}

// For high-volume: rotate sessions (new session = new IP)
async function newSession(country = 'ro') {
  const { browser, page } = await launchHuman({ country });
  return { browser, page };
}
```

---

## Proxy troubleshooting

**Port blocked by host:**
```bash
# Test if proxy port is reachable
timeout 5 bash -c 'cat < /dev/tcp/ro.decodo.com/13001' && echo "PORT OPEN" || echo "PORT BLOCKED"
# If blocked, try alt port 10000 or 10001
```

**Test proxy with curl:**
```bash
curl -sx "http://USER:PASS@ro.decodo.com:13001" https://ifconfig.me
curl -sx "http://USER:PASS@ro.decodo.com:13001" -X POST https://httpbin.org/post -d '{"x":1}'
# Both should return a Romanian IP and 200 status
```

**Check Bright Data zone status:**
- POST blocked = KYC required → brightdata.com/cp/kyc
- 402 error = zone over quota or wrong zone name
- `mcp_unlocker` zone is DEAD (deleted) — use `residential_proxy1_roma` zone

**Provider-specific notes:**
- Decodo: `ro.decodo.com:13001` — Romania-specific endpoint, no country suffix in username
- Bright Data: `brd.superproxy.io:33335` — add `-country-ro` suffix + `-session-ID` for sticky sessions
- IPRoyal: add country/session to PASSWORD, not username: `PASS_country-ro_session-X_lifetime-30m`
