popups

An agent skill by coreyhaines31, from coreyhaines31/marketingskills. Tags: analytics, conversion, design, optimization, web.

What it does

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.

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add coreyhaines31/marketingskills --skill popups

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/coreyhaines31/marketingskills
cp -r marketingskills/skills/popups ~/.claude/skills/popups

Safety box score

Grade A, minimal risk: 4 of 100 risk points, rated 2026-10-21. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This skill is documentation-only and does not ship executable code, network clients, or installers. Its main effect is to steer an agent toward designing marketing popups and banners, which can affect user experience and conversion strategy but not the machine itself; the only real local reach is reading an optional product-marketing context file if present.

Category levels, from 0 (none) to 3 (high)
Category	Level	Why
Code & shell execution	0 (none)	No scripts, shell commands, or code evaluation are included; the repository contents are just `SKILL.md` and `evals.json`.
Network access	0 (none)	The skill does not download remote content or send data to any host; it only discusses popup strategy.
Filesystem reach	1 (low)	It tells the agent to read local context files if present: `If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename...)`.
Secrets & credentials	0 (none)	It does not ask for passwords, tokens, `.env` files, browser sessions, or other credentials.
Privilege & persistence	0 (none)	There is no sudo, service registration, global install, or OS/shell configuration step.
Instruction hijack surface	0 (none)	I found no prompt-injection payloads, hidden text, or instructions to ignore higher-priority rules; the content is ordinary task guidance.
Irreversible actions	0 (none)	The skill only advises on popup design and testing; it does not send messages, publish, deploy, purchase, or delete anything.
Transparency	0 (none)	All supplied files are readable markdown/JSON; there are no binaries, encoded blobs, or unpinned installers.

Before installing

Read `SKILL.md` and confirm it is guidance-only, with no bundled code or scripts.
Check whether `.agents/product-marketing.md` / `.claude/product-marketing.md` exists and whether you want the agent to use that extra local context.
If you care about user-experience risk, review the sections on exit intent, urgency, and frequency capping before enabling it for production marketing work.
