Browser

You can drive a real Chromium running inside this container. With this skill active, the browser core starts automatically and you have browser_* MCP tools attached over CDP to the live shared session. If the user opens the Browser pane, they see the same browser and can log in by hand; you inherit that session's cookies without handling credentials.

This skill is for the Live Agent Browser only. For one-off public screenshots, recordings, or cookie-authenticated headless recipes, use /workspace/scripts/browser.mjs instead.

How to work

Use a hybrid perception loop:

1. browser_navigate, then browser_snapshot. The snapshot is the default

way to read structure, text, roles, and element refs.

1. Take a screenshot when the task is visual: layout verification, charts,

maps, canvas, image content, custom widgets, anything opaque or missing from the snapshot, and after actions with visible consequences.

1. Act through refs when the snapshot gives reliable targets. Use

screenshot-grounded coordinate interaction when the DOM is misleading.

1. Observe again after each action with browser_snapshot,

browser_take_screenshot, or browser_wait_for. Do not assume an action worked.

Keep screenshot cost bounded: viewport screenshots by default, JPEG/moderate quality when options are available, full-page screenshots only when needed. The viewport is 1366x768 and maps 1:1 to OS-level fallback coordinates.

Pacing

Wait for navigation/load states before acting. Use browser_wait_for when content is dynamic. Take one meaningful action, then observe. Avoid blind multi-action bursts, especially on authenticated sites.

Logging in

This browser exits via the container's datacenter IP, so strict providers may show verification challenges. If a task needs a login or challenge response:

1. Ask the user to open the Browser pane and log in by hand.
2. Wait until they say the login is complete.
3. Continue with the browser_* tools against the shared session.

Never type the user's credentials yourself.

OS-level input fallback

Use the browser_* tools first. If a site visibly swallows or rejects CDP input, fall back to X-server input with coordinates from a screenshot:

sh /workspace/.browser-gui/human-input.sh move 640 420
sh /workspace/.browser-gui/human-input.sh click 640 420
sh /workspace/.browser-gui/human-input.sh type "text to type"
sh /workspace/.browser-gui/human-input.sh key Tab Return
sh /workspace/.browser-gui/human-input.sh scroll -3

Coordinates map to the browser window at 0,0 on the 1366x768 display.

Write policy

Reading (search, timelines, messages) is fine on your own. Before any public or irreversible write - posting, replying, DMing, following, buying, or changing settings - say exactly what you're about to do and get the user's confirmation first. They can watch and stop you in the Browser pane.
