What it does
Interstitials is an agent skill from thedaviddias/Front-End-Checklist. Use when applies to CSS and JavaScript implementations of modals, overlays, pop-ups, cookie banners, newsletter sign-up dialogs, and promotional overlays. Check for position: fixed, position: absolute with large z-index, backdrop overlays, and JavaScript that shows modals on page load or shortly after. Consider both SEO impact (Google) and accessibility (WCAG focus management).
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
It sits in Frontend & Design, covering Accessibility and Newsletters. It works with JavaScript. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it
- Applies to CSS and JavaScript implementations of modals
- Newsletter sign-up dialogs
- Promotional overlays
Example prompts
- “/interstitials”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
frontendchecklist.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Interstitials loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 547 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Avoid intrusive interstitials
Intrusive interstitials are a barrier for screen reader users who may not know a modal is blocking the page — they hear content that appears interactive but cannot activate it. Keyboard users may find focus trapped behind an overlay with no way to dismiss it. Users on mobile are most affected visually, as full-screen pop-ups eliminate all access to content until dismissed. Additionally, Google Search penalizes mobile pages with intrusive interstitials in search rankings.
Quick Reference
- Full-screen pop-ups that cover the main content immediately on mobile page load are penalized by Google Search (January 2017 Intrusive Interstitials Update)
- Acceptable interstitials: age verification, legally required notices (cookie consent where legally mandated), login walls for private content
- Unacceptable: pop-ups covering the main content area on mobile that are not easy to dismiss
- For accessibility: modal dialogs must trap focus, be dismissible by keyboard (Escape key), and return focus to the trigger element
- WCAG 2.1 SC 2.1.2 (No Keyboard Trap): users must be able to move focus away from any component using the keyboard
Check
Identify elements using position: fixed or position: absolute with high z-index values that cover significant portions of the viewport. For each: (1) Does it appear on page load or within a few seconds? (2) Does it cover more than a small portion of the main content on mobile screens (< 600px width)? (3) Is it easily dismissible — is there a visible close button with an accessible name? (4) Can it be dismissed by pressing the Escape key? (5) Does focus move into the dialog when it opens and return to the trigger when it closes? Flag dialogs that fail any of these checks.
Show full SKILL.md (271 more words)Show less
Fix
(1) Replace full-screen page-load pop-ups with: (a) sticky banners at the top or bottom (max-height 10-15% of viewport), (b) inline content blocks within the page, or (c) slide-in panels that do not cover the main content. (2) For legally required notices, use small sticky banners rather than full-screen overlays. (3) For all modal dialogs that must be used: implement ARIA dialog pattern — add role='dialog', aria-modal='true', aria-labelledby pointing to the dialog title; trap focus within the dialog using a focus trap; move focus to the first focusable element inside the dialog on open; close on Escape key; return focus to the trigger element on close. (4) Delay non-critical pop-ups until user interaction rather than triggering on page load.
Explain
Intrusive interstitials create two categories of problems: (1) SEO: Google's Intrusive Interstitials Update (2017) penalizes pages that show pop-ups covering the main content on mobile immediately after navigating from search results. Exempt are legally required notices, age verification, and login walls for gated content. (2) Accessibility: A modal dialog that does not manage focus is a WCAG failure. If a screen reader user cannot tell a dialog has appeared, or cannot navigate to it, or is trapped in it without being able to escape, the page fails WCAG 2.1 SC 2.1.2 (No Keyboard Trap) and SC 4.1.3 (Status Messages). The WAI-ARIA dialog pattern requires focus management as a baseline requirement.
