Web Browser Skill

Minimal CDP tools for collaborative site exploration.

Start Chrome

./tools/start.js              # Fresh profile
./tools/start.js --profile    # Copy your profile (cookies, logins)

Start Chrome on :9222 with remote debugging. Auto-detects platform (macOS/Linux/WSL) and searches for Chrome/Chromium. On WSL, automatically adds --no-sandbox flag.

Navigate

./tools/nav.js <https://example.com>
./tools/nav.js <https://example.com> --new

Navigate current tab or open new tab.

Evaluate JavaScript

./tools/eval.js 'document.title'
./tools/eval.js 'document.querySelectorAll("a").length'
./tools/eval.js 'JSON.stringify(Array.from(document.querySelectorAll("a")).map(a => ({ text: a.textContent.trim(), href: a.href })).filter(link => !link.href.startsWith("https://")))'

Execute JavaScript in active tab (async context). Be careful with string escaping, best to use single quotes.
