Cloakbrowser

Stealth Chromium browser automation that bypasses bot detection. Use this skill whenever the user wants to scrape, screenshot, PDF, or automate a site that blocks normal headless browsers — Cloudflare Turnstile, reCAPTCHA v3, FingerprintJS, ShieldSquare, BrowserScan, "Access Denied" responses, suspicious 403/429s on plain `curl`, or any site where Playwright/Puppeteer get caught. Also use when the user mentions CloakBrowser, stealth Chromium, anti-bot bypass, "headless detection", "real Chrome fingerprint", or wants a one-off "what does this page actually render" check.

# CloakBrowser

A patched-source Chromium plus a Playwright-shaped Python wrapper. Fingerprints
are modified at the C++ level (canvas, WebGL, audio, fonts, WebRTC, TLS, CDP
input, `navigator.webdriver`, plugin list, `window.chrome`, …) so detection
services see a real browser because it **is** a real browser — no JS shim that
breaks on the next Chrome upgrade.

## Install state on this VPS

Already installed:

- `cloakbrowser` CLI lives at `/home/node/.local/bin/cloakbrowser` in the
  stable OpenClaw container image.
- Stealth Chromium binary lives at
  `/home/node/.cloakbrowser/chromium-<version>/chrome`.
- Wrapper Python is exposed through `/usr/local/bin/cloakbrowser-python`; the
  bundled scripts use this stable wrapper so they work even when Codex sets
  `HOME` to an isolated session directory.

If a fresh checkout or a new machine needs setting up:

```bash
uv tool install cloakbrowser
cloakbrowser install        # downloads the ~206 MB Chromium binary
```

The `cloakbrowser` CLI only manages the binary (`install`, `info`, `update`,
`clear-cache`). It is **not** a scraper — for that, use the scripts in this
skill or write inline Python.
