popups makes Claude act as a popup conversion expert. It picks the popup type and trigger, writes headline, subhead, button and decline copy, and sets who sees it and how often.

It triggers on exit intent, modals, overlays, slide-ins, sticky bars and notification bars. It also checks privacy, accessibility and Google guidelines. The folder bundles an evals file and no scripts.

Good for

Marketers adding email capture, discount or announcement popups
E-commerce and SaaS teams fixing a popup that annoys visitors
Designers who need copy formulas and mobile rules for overlays

What's in the skill

When it loads

When the user wants to create or optimize popups, modals, overlays, slide-ins, or banners for conversion purposes. Also use when the user mentions "exit intent," "popup conversions," "modal optimization," "lead capture popup," "email popup," "announcement banner," "overlay," "collect emails with a popup," "exit popup," "scroll trigger," "sticky bar," or "notification bar." Use this for any overlay or interrupt-style conversion element. For forms outside of popups, see cro. For general page conversion optimization, see cro.

Questions

How do I install popups?

Use the install box above. The repo README also documents the full marketing-skills plugin for Claude Code and Codex, and a one-skill ZIP for the Claude web app on the repo's Releases page.

Do I need the product-marketing skill first?

No. The SKILL.md only says to read a product marketing context file if one exists (.agents/product-marketing.md, .claude/product-marketing.md or the older product-marketing-context.md) and to ask you for anything it does not cover. The README calls product-marketing the foundation the other skills check first.

Does it cover exit-intent popups?

Yes. Exit intent is both a trigger strategy and a popup type in the SKILL.md.

Does it cover privacy and accessibility?

It has sections for GDPR and privacy, accessibility and Google guidelines. Treat them as a checklist, not legal advice.

How is it different from the cro skill?

The SKILL.md says to use popups for any overlay or interrupt-style conversion element, and to see cro for forms outside popups and for general page conversion. Its related-skills list also points to cro for the form inside the popup.

Does popups work in the Claude app or Codex?

The README documents a Codex plugin and a one-skill ZIP for the Claude web app, uploaded under Customize, then Skills. Claude Code is covered by the skills CLI and the plugin.

Does popups need an API key or scripts?

The SKILL.md names no API keys, and the skill folder bundles no scripts. It holds the SKILL.md and an evals file.

Is popups safe?

It is plain text instructions with no bundled scripts, so what it can do depends on your client's own permissions.
