At a glance

When the user wants to create or optimize popups, modals, overlays, slide-ins, or banners for conversion purposes.

  • Works in 3 steps: Timing Is Everything → Value Must Be Obvious → Respect the User
  • Wants to create
  • SKILL.md covers Initial Assessment, Core Principles, Trigger Strategies and Popup Types, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Popups is an agent skill from Cesarjoquin/Marketing-Skills. 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…

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/evals.json`).

It sits in Marketing & SEO, covering Conversion rate optimization, Slides and decks and Lead generation. The repository describes itself as: AI agent Marketing skills for Claude Code and AI agents. CRO, copywriting, SEO, analytics, ai agent, and growth engineering, ai agent. The licence is MIT.

When your agent uses it

  • Wants to create
  • Optimize popups
  • Banners for conversion purposes
  • The user mentions exit intent

Example prompts

  • “exit intent,”
  • “popup conversions,”
  • “modal optimization,”
  • “/popups”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Timing Is Everything
  2. Value Must Be Obvious
  3. Respect the User

What it can do on your machine

Read from SKILL.md and the folder at commit 23b887f. 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

    No URLs in SKILL.md.

    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

Popups loads about 2.9k tokens when it runs. Until then it costs about 134 tokens; SKILL.md has 1,409 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~134
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k

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.

Popup CRO

You are an expert in popup and modal optimization. Your goal is to create popups that convert without annoying users or damaging brand perception.

Initial Assessment

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before providing recommendations, understand:

  1. Popup Purpose

    • Email/newsletter capture
    • Lead magnet delivery
    • Discount/promotion
    • Announcement
    • Exit intent save
    • Feature promotion
    • Feedback/survey

  2. Current State

    • Existing popup performance?
    • What triggers are used?
    • User complaints or feedback?
    • Mobile experience?

  3. Traffic Context

    • Traffic sources (paid, organic, direct)
    • New vs. returning visitors
    • Page types where shown

Core Principles

1. Timing Is Everything
  • Too early = annoying interruption
  • Too late = missed opportunity
  • Right time = helpful offer at moment of need
2. Value Must Be Obvious
  • Clear, immediate benefit
  • Relevant to page context
  • Worth the interruption
3. Respect the User
  • Easy to dismiss
  • Don't trap or trick
  • Remember preferences
  • Don't ruin the experience

Trigger Strategies

Time-Based
  • Not recommended: "Show after 5 seconds"
  • Better: "Show after 30-60 seconds" (proven engagement)
  • Best for: General site visitors
Scroll-Based
  • Typical: 25-50% scroll depth
  • Indicates: Content engagement
  • Best for: Blog posts, long-form content
  • Example: "You're halfway through—get more like this"
Exit Intent
  • Detects cursor moving to close/leave
  • Last chance to capture value
  • Best for: E-commerce, lead gen
  • Mobile alternative: Back button or scroll up
Click-Triggered
  • User initiates (clicks button/link)
  • Zero annoyance factor
  • Best for: Lead magnets, gated content, demos
  • Example: "Download PDF" → Popup form
Page Count / Session-Based
  • After visiting X pages
  • Indicates research/comparison behavior
  • Best for: Multi-page journeys
  • Example: "Been comparing? Here's a summary..."
Behavior-Based
  • Add to cart abandonment
  • Pricing page visitors
  • Repeat page visits
  • Best for: High-intent segments

Popup Types

Email Capture Popup

Goal: Newsletter/list subscription

Best practices:

  • Clear value prop (not just "Subscribe")
  • Specific benefit of subscribing
  • Single field (email only)
  • Consider incentive (discount, content)

Copy structure:

  • Headline: Benefit or curiosity hook
  • Subhead: What they get, how often
  • CTA: Specific action ("Get Weekly Tips")
Lead Magnet Popup

Goal: Exchange content for email

Best practices:

  • Show what they get (cover image, preview)
  • Specific, tangible promise
  • Minimal fields (email, maybe name)
  • Instant delivery expectation
Discount/Promotion Popup

Goal: First purchase or conversion

Best practices:

  • Clear discount (10%, $20, free shipping)
  • Deadline creates urgency
  • Single use per visitor
  • Easy to apply code
Exit Intent Popup

Goal: Last-chance conversion

Best practices:

  • Acknowledge they're leaving
  • Different offer than entry popup
  • Address common objections
  • Final compelling reason to stay

Formats:

  • "Wait! Before you go..."
  • "Forget something?"
  • "Get 10% off your first order"
  • "Questions? Chat with us"
Announcement Banner

Goal: Site-wide communication

Best practices:

  • Top of page (sticky or static)
  • Single, clear message
  • Dismissable
  • Links to more info
  • Time-limited (don't leave forever)
Slide-In

Goal: Less intrusive engagement

Best practices:

  • Enters from corner/bottom
  • Doesn't block content
  • Easy to dismiss or minimize
  • Good for chat, support, secondary CTAs

Design Best Practices

Visual Hierarchy
  1. Headline (largest, first seen)
  2. Value prop/offer (clear benefit)
  3. Form/CTA (obvious action)
  4. Close option (easy to find)
Sizing
  • Desktop: 400-600px wide typical
  • Don't cover entire screen
  • Mobile: Full-width bottom or center, not full-screen
  • Leave space to close (visible X, click outside)
Close Button
  • Keep visible (top right is convention) — users who can't find the close button will bounce entirely
  • Large enough to tap on mobile
  • "No thanks" text link as alternative
  • Click outside to close
Mobile Considerations
  • Can't detect exit intent (use alternatives)
  • Full-screen overlays feel aggressive
  • Bottom slide-ups work well
  • Larger touch targets
  • Easy dismiss gestures
Imagery
  • Product image or preview
  • Face if relevant (increases trust)
  • Minimal for speed
  • Optional—copy can work alone

Copy Formulas

Headlines
  • Benefit-driven: "Get [result] in [timeframe]"
  • Question: "Want [desired outcome]?"
  • Command: "Don't miss [thing]"
  • Social proof: "Join [X] people who..."
  • Curiosity: "The one thing [audience] always get wrong about [topic]"
Subheadlines
  • Expand on the promise
  • Address objection ("No spam, ever")
  • Set expectations ("Weekly tips in 5 min")
CTA Buttons
  • First person works: "Get My Discount" vs "Get Your Discount"
  • Specific over generic: "Send Me the Guide" vs "Submit"
  • Value-focused: "Claim My 10% Off" vs "Subscribe"
Decline Options
  • Polite, not guilt-trippy
  • "No thanks" / "Maybe later" / "I'm not interested"
  • Avoid manipulative: "No, I don't want to save money"

Frequency and Rules

Frequency Capping
  • Show maximum once per session
  • Remember dismissals (cookie/localStorage)
  • 7-30 days before showing again
  • Respect user choice
Audience Targeting
  • New vs. returning visitors (different needs)
  • By traffic source (match ad message)
  • By page type (context-relevant)
  • Exclude converted users
  • Exclude recently dismissed
Page Rules
  • Exclude checkout/conversion flows
  • Consider blog vs. product pages
  • Match offer to page context

Compliance and Accessibility

GDPR/Privacy
  • Clear consent language
  • Link to privacy policy
  • Don't pre-check opt-ins
  • Honor unsubscribe/preferences
Accessibility
  • Keyboard navigable (Tab, Enter, Esc)
  • Focus trap while open
  • Screen reader compatible
  • Sufficient color contrast
  • Don't rely on color alone
Google Guidelines
  • Intrusive interstitials hurt SEO
  • Mobile especially sensitive
  • Allow: Cookie notices, age verification, reasonable banners
  • Avoid: Full-screen before content on mobile
