| description | General browser automation — drive Chrome/Chromium over CDP (navigate, click, type, eval, screenshot, snapshot) via the agent-browser CLI. Use for normal or authenticated/logged-in browsing. For anonymous bot-walled / Cloudflare targets (i.e. "stealth" browsing) use the cloak-browser skill instead; for logged-in sites, inject real cookies (see below). |
agent-browser
agent-browser (vercel-labs) is a CDP browser-automation CLI. It drives an
external Chrome/Chromium — it ships no browser of its own.
Full command reference: run agent-browser skills get core --full — it
prints agent-browser's own up-to-date guide (verbs, sessions, --state,
--profile, network, tabs). Read it from the tool rather than duplicating it.
Typical loop:
agent-browser --session s open https://example.com
agent-browser --session s snapshot
agent-browser --session s eval "document.title"
agent-browser --session s close
When to use which
| Situation | Tool |
|---|
| Normal / cooperative site | agent-browser |
| Logged-in / authenticated (your real HubSpot, Gmail, …) | agent-browser + injected real cookies — your genuine, stable identity |
| Anonymous site behind a bot wall (Cloudflare, fingerprinting, sannysoft) | the cloak-browser skill (rotating stealth fingerprint) |
Do not use cloak-browser for authenticated work: its per-launch fingerprint
rotation over a logged-in account reads as account-takeover.
Authenticated sites
To drive a site you're already logged into, lift your real browser cookies and
inject them rather than re-authenticating. The reliable recipe (rookiepy →
Playwright state JSON → agent-browser --state, plus why attaching to running
Chrome / copied profiles fail) is captured in the drive_authed_browser_rookiepy
memory. Load a saved state with agent-browser --state <file> open <url>.
Notes
- One browser per
--session, launched on first open; close when done.
close --all before switching --profile/--state, or a stale daemon
silently ignores them.
- Don't share a
--session name between agent-browser and cloak-browser — the
first to launch the daemon wins, so the other silently reuses its browser.
- The binary comes from nix-config (llm-agents.nix); this skill is docs only.
