cloakbrowser

name: cloakbrowser description: Use to crawl websites with stealth Chromium (57 C++ fingerprint patches) via agent-browser CLI.

CloakBrowser

Stealth Chromium with source-level anti-detect patches, driven by agent-browser CLI.

Crawl

~/.claude/skills/cloakbrowser/scripts/crawl.py <url1> [url2] ...

Strips noise, unwraps links inline, returns clean text. Output saved to CRAWL_OUTPUT_DIR if set.

DDG Search

~/.claude/skills/cloakbrowser/scripts/ddg-search.py "your query"

Free, unlimited DuckDuckGo search. Saves JSONL to $DDG_SEARCH_OUTPUT_DIR (default /tmp).

~/.claude/skills/cloakbrowser/scripts/ddg-search.py "your query"        # page 1
~/.claude/skills/cloakbrowser/scripts/ddg-search.py "your query" --page 2  # page 2

Custom Exploration

Ad-hoc browser exploration with full Playwright API + humanize patches.

~/.claude/skills/cloakbrowser/scripts/custom.py <url>              # Open URL, print title + text
~/.claude/skills/cloakbrowser/scripts/custom.py <url> --eval <js>  # Run JS and print result
~/.claude/skills/cloakbrowser/scripts/custom.py <url> --snapshot   # Print accessibility snapshot
~/.claude/skills/cloakbrowser/scripts/custom.py <url> --html       # Print page HTML

See references/usage.md for the full Python CDP pattern.

Key Concepts

• CloakBrowser binary — ~/.cloakbrowser/chromium-*/chrome with 58 C++ fingerprint patches
• Stealth — get_default_stealth_args() + time-based fingerprint. READ stealth.
• agent-browser daemon — auto-starts on first command, persists across CLI calls, auto-shutdowns after idle
• Tab-per-call — each invocation opens a tab, works, closes it. Daemon stays alive
• Concurrency — multiple calls share one browser instance (~600MB), each gets its own tab
• RAM lifecycle — 0MB idle → ~600MB active → 0MB after 5min idle

Environment Variables

Notes

• Stealth — see stealth.md (source-linked to CloakHQ README)
• humanize — on by default in connect_cdp() per README
• Challenges — wait_for_challenge() for Turnstile
• 2Captcha / CapSolver — Paid API fallbacks (~$3/1000 solves). Not integrated.
