Web Browser Skill

Minimal CDP tools for collaborative site exploration.

Start Chrome

./scripts/start.js              # Fresh profile
./scripts/start.js --profile    # Copy your profile (cookies, logins)
./scripts/start.js --headless   # No GUI needed (e.g. on headless servers)

Start Chrome on :9222 with remote debugging. Requires google-chrome installed on Linux.

If Chrome was already started by a previous run but has become a zombie (port taken but not responding), start.js will automatically kill the stale process and restart. If it fails to start, it prints the Chrome stderr log and suggests fixes.

Navigate

./scripts/nav.js https://example.com
./scripts/nav.js https://example.com --new

Navigate current tab or open new tab.

Evaluate JavaScript

./scripts/eval.js 'document.title'
./scripts/eval.js 'document.querySelectorAll("a").length'
./scripts/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.

Screenshot

./scripts/screenshot.js

Screenshot current viewport, returns temp file path

Pick Elements

./scripts/pick.js "Click the submit button"

Interactive element picker. Click to select, Ctrl+Click for multi-select, Enter to finish.

Dismiss Cookie Dialogs

./scripts/dismiss-cookies.js          # Accept cookies
./scripts/dismiss-cookies.js --reject # Reject cookies (where possible)

Automatically dismisses EU cookie consent dialogs.

Run after navigating to a page:

./scripts/nav.js https://example.com && ./scripts/dismiss-cookies.js

Background Logging (Console + Errors + Network)

Automatically started by start.js and writes JSONL logs to:

~/.cache/agent-web/logs/YYYY-MM-DD/<targetId>.jsonl

Manually start:

./scripts/watch.js

Tail latest log:

./scripts/logs-tail.js           # dump current log and exit
./scripts/logs-tail.js --follow  # keep following

Summarize network responses:

./scripts/net-summary.js
