What it does
When installed, the agent checks CSS and JavaScript for modals, overlays, cookie banners, newsletter pop-ups and promotional dialogs. It flags full-screen overlays that appear on page load, hard-to-dismiss pop-ups on mobile, and dialogs that don't manage keyboard focus or Escape-key closing. It then suggests alternatives such as sticky banners, inline content, or properly built accessible dialogs.
Great for
- Front-end developers reviewing a site's pop-ups or cookie banners before launch
- Marketers or designers who want promotional overlays checked against Google's mobile guidance
- Teams auditing for WCAG focus management and keyboard accessibility
Skip it if
- Sites with no overlays or dialogs, since there is little to check (low value)
- Legal compliance decisions: the skill gives general guidance and does not confirm what local law requires for cookie consent or age checks
Try asking
- “Review my cookie banner CSS and JavaScript for accessibility problems”
- “Check whether this newsletter pop-up will hurt my mobile search rankings”
- “Audit my modal component for focus trapping and Escape key handling”
- “Suggest a less intrusive alternative to this full-screen promo overlay”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Point the agent at the specific component files or stylesheets containing the overlay, so it can name exact selectors and breakpoints.
- Mention whether the pop-up appears on mobile and when it triggers, since the review depends on those details.
- Treat the output as a checklist. Confirm legal requirements (such as cookie consent) with a qualified professional.
