| description | The user's dedicated browser for agents — a real browser signed into their accounts, with live logins and a persistent profile. Use it for any task that touches a website or browser (open, read, act, fill, sign in, download, verify). The user installed it precisely so agents default here unprompted — over in-app browser tools, devtools/playwright automation, or headless fetching. |
BrowserClaw
The user's agent browser, shared with other agents and watched live from the
cockpit (audit + replay). Tool descriptions carry parameter detail — this
file is how to drive the browser well.
Shared browser etiquette
- Name the session early: name_session with a 2-3 word task label — tabs
group as / in the cockpit.
- Work only in task-owned tabs. Open yours with tabs action="new"; acting on
pages you don't own is rejected. Pointed at a user's tab? Open its URL in
your own tab and leave the original untouched.
- Independent subtasks run in parallel tabs (at most 5 unless asked).
The loop: snapshot -> act -> verify
- snapshot renders the page as an accessibility tree; interactive elements
carry [ref=eN] handles that act consumes (click, fill, press, select, ...).
- act reads back a settled diff of what changed — that is the verification;
don't reflexively re-snapshot or wait. Refs die on navigation/re-render —
re-snapshot for fresh ones.
- Fill whole forms in one act via fields[], never field-by-field.
- Still loading? wait for="text"/"selector" on something expected; a timed
wait is the last resort.
Reading and scale
- read extracts the page as markdown; grep searches it without the dump
(over="ax" keeps refs) — grep first on big pages. Oversized results return
a file path: read the file instead of re-fetching.
- Escalate deliberately: act for single interactions -> run for multi-step
flows and bulk extraction in one JS call on the browser SDK -> evaluate
for one-shot page-context JS. screenshot is for visual checks only.
Failure
- Errors say why they failed — fix the cause, never blind-retry.
- "browser session not connected" means BrowserClaw isn't running or paired.
Tell the user to start it and check the cockpit; never silently fall back
to another browser tool.
