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:
   • NexisClaw 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".
   • Use tabId handles like t1 or labels like meet as targetId in later calls.
   • Avoid relying on raw DevTools targetId unless the tool just returned it.
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.
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.

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:

{ "action": "tabs" }

If no suitable tab exists:

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

Then target it by label:

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

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

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

Do not pass bare numbers like "2" as targetId. Numeric tab positions are only for the CLI NexisClaw 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.

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

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.
