Is the CloakBrowser skill free?

Yes. The skill itself is free from OctavianTocan/cloakbrowser-skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the CloakBrowser SkillProof Score?

7.2/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 4/5.

How do I install CloakBrowser?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use CloakBrowser with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

CloakBrowser

Wraps a third-party stealth-Chromium tool for anti-bot scraping, but needs a 206 MB proprietary binary the repo doesn't ship.

Test report

Verdict: Works with setup
Score: 7.2/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · fcc0b03

The scripts and argparse surface are clean and well-designed (all 6 py_compile cleanly, --help works standalone), and a local throwaway anti-bot server on 127.0.0.1 confirmed the real problem it targets (plain curl gets a 403, a browser-shaped UA gets 200) — but I could not verify the actual bypass claim because every script needs a separate uv/pipx install plus a ~206 MB proprietary Chromium binary from CloakHQ that isn't in this repo, and even the skill's own README admits its stealth codepaths were 'not end-to-end verified against a real protected target.'

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 4/5
Triggers reliably 5/5
Output vs. baseline 5/10
Docs & honesty 4/5

What CloakBrowser does

A thin CLI wrapper (fetch/screenshot/pdf/eval-js/serve scripts) around the separate CloakHQ/CloakBrowser project, a patched Chromium that spoofs browser fingerprints at the C++ level to get past Cloudflare Turnstile, reCAPTCHA v3, and similar bot-detection. Triggers well on bot-detection language ('403 on curl', 'Playwright got caught', 'CloakBrowser'), but every script fails until the user separately runs install.sh to pull the CloakBrowser package via uv/pipx and download its ~206 MB patched Chromium binary — a real external, separately-licensed dependency not included in this GitHub repo.

How to install CloakBrowser

git clone https://github.com/OctavianTocan/cloakbrowser-skill
mkdir -p ~/.claude/skills
cp -r cloakbrowser-skill ~/.claude/skills/cloakbrowser
~/.claude/skills/cloakbrowser/install.sh   # separately installs CloakBrowser + downloads ~206MB patched Chromium

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger CloakBrowser

/cloakbrowser Wraps a third-party stealth-Chromium tool for anti-bot scraping, but needs a 206 MB proprietary binary the repo doesn't ship.

It also activates on plain-language prompts like these:

curl keeps getting a 403 from this site, how do I get past the bot check
playwright got flagged by Cloudflare Turnstile, need a way around it
grab a screenshot of this page even though it blocks headless browsers
