dym-browser-use-cloud

dym-browser-use-cloud is a skill for Claude Code from Rheinmir/setup. It costs 87 tokens per session (1,210 once invoked), scanned A, original, MIT.

A service for running browser tasks in separate cloud browsers instead of the user's local browser. It can also expose a local development site through a temporary internet tunnel.

In plain words
What is it for?
Use it to test a local site from a clean browser, run several browser flows independently, or work with sites that use bot checks.
Why use it?
It avoids shared tabs, extensions, and login sessions, and can provide separate environments for parallel tasks or sites that block local automation.

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

dym-browser-use-cloud scanned grade A with 1 finding 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 yesterday.

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.

When to use

  • Nhiều luồng chạy song song — Chrome cục bộ là một trình duyệt dùng chung, các luồng giành tab và focus lẫn nhau. Mỗi luồng một cloud browser thì cô lập hẳn.
  • Cần môi trường sạch — không extension, không session đăng nhập sẵn của user, không giẫm lên tab user đang làm.
  • Site chặn bot / captcha — cloud browser có IP quản lý sạch và cấu hình stealth.

KHÔNG dùng khi chỉ verify một trang nội bộ — trả tiền vô ích. Dùng /dym-browser-use repl.

Chi phí (theo tài liệu browser-use, CHƯA tự kiểm chứng — không có API key khi khảo sát)

~$0.01/task + ~$0.006/step + $0.02/giờ browser. Cloud browser tính tiền tới khi dừng hoặc hết hạn — luôn stop_remote_daemon(name) khi xong.

Steps

  1. Auth: browser-harness auth login, hoặc printf '%s' "$BROWSER_USE_API_KEY" | browser-harness auth login --api-key-stdin.
  2. Tunnel localhost — BẮT BUỘC --host-header=rewrite. Cloud browser nằm ngoài Internet, không với tới cổng cục bộ. 
    ngrok http 3000 --host-header=rewrite --log=stdout > /tmp/qa-ngrok.log 2>&1 &
sleep 3
PUBLIC_URL=$(curl -s http://127.0.0.1:4040/api/tunnels \
  | python3 -c 'import sys,json; print(json.load(sys.stdin)["tunnels"][0]["public_url"])')
curl -s -H "ngrok-skip-browser-warning: true" "$PUBLIC_URL" | head -c 200   # kiểm tới APP chưa
    Không có ngrok / không auth được → cloudflared tunnel --url http://127.0.0.1:3000 (không cần tài khoản, không có trang interstitial).
  3. Dựng cloud browser — TẮT proxy: 
    browser-harness <<'PY'
start_remote_daemon("qa", proxyCountryCode=None)   # proxy mặc định làm hỏng TLS của ngrok
PY
BU_NAME=qa browser-harness <<PY
new_tab("about:blank")
cdp("Network.setExtraHTTPHeaders", headers={"ngrok-skip-browser-warning": "true"})
goto_url("$PUBLIC_URL")
wait_for_load()
print(page_info())     # PHẢI ra title thật của app — không phải chrome-error/403/interstitial
PY
  4. Dọn — trên MỌI nhánh: pkill -f "ngrok http 3000" và stop_remote_daemon("qa") (đúng tên hàm — KHÔNG phải stop_daemon).

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.
