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)

Start Chrome on :9222 with remote debugging.

start.js auto-detects Chrome/Chromium, including Playwright-managed binaries under /opt/ms-playwright and ~/.cache/ms-playwright. Use CHROME_BIN to force a path.

Navigate

./scripts/nav.js https://example.com
./scripts/nav.js https://example.com --new
./scripts/nav.js https://idp.example/auth --url-contains keycloak

Navigate current tab or open new tab.

Targeting flags (supported by nav/eval/screenshot/click/type/wait):

• --url-contains <fragment>: select tab whose URL contains fragment
• --target-id <id>: use specific CDP target id
• --wait-new-tab: wait for a newly opened tab/page (popup/new-tab auth flows)
• --timeout-ms <ms>: override timeout

Evaluate JavaScript

./scripts/eval.js 'document.title'
./scripts/eval.js 'document.querySelectorAll("a").length'
./scripts/eval.js --url-contains keycloak 'location.href'

Execute JavaScript in selected tab (async context). Be careful with string escaping; single quotes are easiest.

First-class click/type/wait helpers

./scripts/click.js '#kc-login'
./scripts/type.js '#username' 'nick'
./scripts/type.js '#password' 'ChangeMe1234!'
./scripts/wait.js --url-contains '/hub/home'
./scripts/wait.js --wait-new-tab --url-contains keycloak

These helpers reduce brittle one-off JS snippets and improve auth-flow reliability.

Screenshot

./scripts/screenshot.js
./scripts/screenshot.js --url-contains '/hub/home'

Screenshot selected viewport; prints temp file path.

Pick Elements

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

Interactive element picker. Click to select, Cmd/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
