Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

popup-cro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to popups — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 453 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 .claude/product-marketing-context.md exists, 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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
