Dismiss Cookie Banner

When to invoke

On the first interaction after navigating to a new page, before the agent attempts to interact with content. Especially relevant for sites in EU, UK, California, or Chinese jurisdictions, where banners are near-universal.

The matcher will assign this skill a high score when:

• is_initial_load = true
• cookies_present = true and DOM contains a cookie-related marker

Recipe

1. wait_for_dom_ready timeout=2s
2. wait extra=400ms
3. try_each selectors=[ "#onetrust-accept-btn-handler", "button#onetrust-pc-btn-handler", ".cc-allow", ".cc-accept-all", "button.cookie-accept", "button:has-text('Accept all cookies')", "button:has-text('Accept All Cookies')", "button:has-text('Accept all')", "button:has-text('Accept cookies')", "button:has-text('I Agree')", "button:has-text('Agree and continue')", "button:has-text('Got it')", "[aria-label*='Accept' i][aria-label*='cookie' i]", "[data-testid*='cookie-banner-accept']", "[data-cookieconsent='accept']", ] action=click on_success=stop timeout=1500ms
4. wait extra=300ms

Success criteria

• assert no_visible_element selector="[aria-label*='cookie' i][role='dialog']" OR no_visible_element selector="#onetrust-banner-sdk" OR no_change_was_needed

When NOT to use

• The user task is about the cookie banner itself — e.g., privacy testing, a screenshot of the pre-consent state, or auditing consent UI.
• The site has already had its banner dismissed in the persistent context (this skill is idempotent but logs an unnecessary execution).

Known failures

• Custom CMS banners (~2% of sites): sites running bespoke consent UIs may not match any of the standard selectors. The vision fallback handles these when an adapter is configured; otherwise the skill returns failed and the agent decides.
• Cross-origin iframe banners (~1%): banners served from a different origin (e.g., embedded consent providers using <iframe>) cannot be clicked through Playwright's default context. We report failed with reason="iframe_cross_origin".
• "Reject all" intent: this skill always accepts. If your task requires rejecting cookies, use the future reject-cookie-banner skill (post-launch) or override the recipe via the agent.

Example usage

Agent: "Go to bbc.com and tell me the top story."
→ matcher selects [dismiss-cookie-banner, verify-page-loaded, extract-text]
→ invoke_skill("dismiss-cookie-banner") → success in 207ms, deterministic_path=true
→ invoke_skill("verify-page-loaded") → success in 84ms
→ agent reads the top story headline directly

Related skills

• verify-page-loaded — typically chained immediately after this one
• dismiss-newsletter-popup — sometimes co-occurs on news sites
• exit-tracking-popup — for the rare "we use cookies for analytics" upsells that aren't the main consent UI
