# Browser Automation

Use this skill when you need the `browser` tool for anything beyond a single page check.

## Operating Loop

1. Check browser state before acting:
   - `openclaw browser doctor` or `action="status"` when the browser/plugin setup itself may be broken.
   - `action="status"` for availability.
   - `action="profiles"` if login state or profile choice matters.
   - `action="tabs"` before opening a new tab if retries/timeouts may have left windows behind.
2. Prefer stable tab handles:
   - Open important tabs with `label`, for example `label="meet"`.
   - After `action="tabs"` or `action="open"`, store `suggestedTargetId` and pass it as `targetId` in later calls.
   - `suggestedTargetId` is the label when one exists, otherwise the stable `tabId` handle like `t1`.
   - Avoid relying on raw DevTools `targetId` except for immediate diagnostics; it can change under Chromium target replacement.
3. Read before you click:
   - Use `action="snapshot"` on the intended `targetId`.
   - Use the same `targetId` for follow-up actions so refs stay on the same tab.
   - For durable Playwright refs, request `refs="aria"` when supported. If you receive `axN` refs from `snapshotFormat="aria"`, use them only after that same snapshot call; stale or unbound `axN` refs fail fast and need a fresh snapshot.
   - Use `urls=true` when link text is ambiguous or a direct navigation target would avoid brittle clicks.
   - Use `labels=true` on snapshot or screenshot when visual position matters. On Playwright-backed profiles, the response includes an `annotations` array (`{ref, number, role, name?, box}`) with each ref's bounding box in the captured image's coordinate space, so you can reason about position without re-snapshotting; screenshot labels can also combine with `fullPage=true` (CLI: `--full-page`) to label the whole document, or `ref` / `element` to clip to one element. `profile="user"` and other existing-session (chrome-mcp) profiles render an overlay into page screenshots but do not attach `annotations` or use the Playwright full-page/ref/element projection helper, so read positions from the labeled image itself on those profiles. The raw-CDP fallback (no Playwright) does not support labeled screenshots at all and returns a 501, so only request `labels` when Playwright is available.
4. Act narrowly:
   - Prefer `action="act"` with a ref from the latest snapshot.
   - After navigation, modal changes, or form submission, snapshot again before the next action.
   - Avoid blind waits. Wait for visible UI state when possible.
5. Report real blockers:
   - If the page needs login, permission, captcha, 2FA, camera/microphone approval, or another manual step, stop and tell the user exactly what is needed.
   - Do not claim the browser is not logged in just because the current page shows a permission or onboarding dialog. Inspect the visible UI first.

## Browser batch CLI

`openclaw browser batch` runs an array of nested `/act` actions in one `/act` call (the same `kind="batch"` runtime reached through the agent tool), so CLI users and scripts can combine actions like `wait`, `click`, `type`, and `evaluate` into a single replayable plan without per-action round trips. Each entry in `actions[]` is a `BrowserActRequest` — the closed union the `/act` route accepts — not arbitrary `openclaw browser` subcommands. `batch` is not supported on `profile="user"` and other existing-session (chrome-mcp) profiles; send actions individually there.

- CLI: `openclaw browser batch --actions '<json>'`, `--actions-file plan.json`, or `--actions-file -` for stdin. `--continue` sets `stopOnError=false`; default stops on first error.
- Ref lifecycle: refs come from a `snapshot` run before the batch (snapshot is not a nested action). A nested action that changes page state — such as a `click` that triggers navigation, or an `evaluate` that mutates the DOM — can invalidate earlier refs for the rest of the batch; put state-changing actions first, or split into a follow-up batch after re-snapshotting. Navigation and re-snapshotting happen outside the batch, since `open`, `navigate`, and `snapshot` are not `/act` kinds.
- Target id: nested actions share the request's tab; an explicit nested `targetId` that resolves to a different tab is rejected with `ACT_TARGET_ID_MISMATCH`.
- Response: `{ "results": [{ "ok": true } | { "ok": false, "error": "..." }, ...] }` in order; with default `stopOnError` the array ends at the first failure. Any failed entry exits nonzero; use `--json` to preserve the full response in scripts.

## Tab Hygiene

Before creating a tab for a named task, list tabs and reuse an existing matching label or URL when it is still usable.

Example:

```json
{ "action": "tabs" }
```

If no suitable tab exists:

```json
{ "action": "open", "url": "https://example.com", "label": "task" }
```

Then target it by label:

```json
{ "action": "snapshot", "targetId": "task", "refs": "aria" }
```

If a retry creates duplicates, close the extras by `tabId`:

```json
{ "action": "close", "targetId": "t3" }
```

Do not pass bare numbers like `"2"` as `targetId`. Numeric tab positions are only for the CLI `openclaw browser tab select 2` helper; browser tool calls need a `suggestedTargetId`, label, `tabId`, or raw target id.

## Stale Ref Recovery

If an action fails with a missing or stale ref:

1. Snapshot the same `targetId` again.
2. Find the current visible control.
3. Retry once with the new ref.
4. If the UI moved to a blocker state, report the blocker instead of looping.

## Existing User Browser

Use `profile="user"` only when existing cookies/login matter. This attaches to the user's running Chromium-based browser.

On macOS, `action="importprofile"` is the alternative when the agent should use an isolated managed browser with cookies copied from a real Chrome-family profile. First use `action="profiles"` and inspect `systemProfiles`, then import into a fresh managed profile name. Import asks for one Keychain/Touch ID consent prompt. It copies cookies, not local storage or IndexedDB; device-bound session credentials (DBSC) mean some Google sessions may still require re-authentication.

For `profile="user"` and other existing-session profiles, omit `timeoutMs` on `act:type`, `hover`, `scrollIntoView`, `drag`, `select`, and `fill`; that driver rejects per-call timeout overrides for those actions. `act:evaluate` accepts `timeoutMs`.

## Google Meet Notes

When creating or joining a Meet:

- Treat camera/microphone permission screens as progress, not login failure.
- If asked whether people can hear you, click the microphone option when voice is required.
- If Google asks for sign-in, 2FA, account chooser confirmation, or permission that needs user approval, report the exact manual action.
- Use one labeled tab per meeting flow, for example `label="meet"`, and reuse it during retries.
