camoufox

camoufox is a skill for Claude Code, Codex from AgentComputerAI/torch. It costs 91 tokens per session (2,041 once invoked), scanned A, original, MIT.

A Firefox-based browser for automated web browsing that changes browser-identifying details at the browser-engine level. These details, often called a browser fingerprint, can be used by websites to recognize automated visitors.

In plain words
What is it for?
Use it for browser scraping in environments without a usable Chrome session. It is intended for concurrent personas and sites where ordinary browser automation is detected.
Why use it?
It provides a browser option when the user’s real Chrome profile is unavailable, such as on a virtual machine, headless server, remote computer, or CI system. It also supports running multiple browser identities.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

camoufox scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Camoufox

Camoufox is a Firefox fork where fingerprint spoofing happens at the C++ engine level — navigator.*, WebGL, Canvas, AudioContext, screen geometry are all rewritten before any JavaScript can inspect them. That makes it structurally more robust than puppeteer-stealth, which patches the same signals via JavaScript shims that anti-bot systems can detect.

For torch, Camoufox is the answer to "my machine can't run the real-Chrome-clone strategy" — VMs, headless servers, CI pipelines, remote boxes with no host Chrome. It's a strict fallback, not a replacement: when 127.0.0.1:9222 is available (the user's real profile), that's still the better choice because it has real cookies, history, and browsing reputation that Camoufox's synthetic fingerprints cannot replicate.

When to activate

Use this skill when:

  • Running on a VM or headless server — no host Chrome to clone, no GUI to drive a headed browser, and puppeteer.launch() with stealth gets detected on hard sites
  • Running in CI — same reasons
  • You need concurrent personas — torch's cloned profile is a single identity; Camoufox's BrowserForge fingerprint generator produces internally-consistent fresh personas on demand (5% Linux, 2560x1440 at 9.5%, Intel HD GPU at 27.5%, etc. matching real-world distributions)
  • The current toolchain is genuinely failing — a site that real-Chrome-clone + stealth + solver + proxy still can't crack (rare, but happens — Interstitial, Kasada, Shape)

Do not use this skill when:

  • The user has a real Chrome profile torch can clone (127.0.0.1:9222 is set) — real profile beats synthetic fingerprint for account-level reputation scoring
  • The site tests specifically for Chrome/Chromium (some sites use V8-specific quirks that SpiderMonkey cannot spoof)
  • You only need to scrape soft targets where vanilla stealth plugin already works

Installation

Camoufox is Python-first. torch drives it from Node via the Playwright server mode.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

camoufox is a skill published in the GitHub repository AgentComputerAI/torch (5 stars, last pushed 6mo ago), licensed MIT. It adds 91 tokens to every session and 2,041 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
