Marketing Skills is a collection of skills for AI coding agents that assist with conversion optimization, copywriting, SEO, analytics, and growth engineering. Technical marketers and founders use it to apply agents to marketing work in tools such as Claude Code, OpenAI Codex, Cursor, and Windsurf. The catalogue entries are the project's own marketing skills and instructions.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00116 | $0.02781 |
| Opus 5.5 | $0.00046 | $0.01112 |
| Sonnet 5.5 | $0.00023 | $0.00556 |
| Haiku 4.5 | $0.00012 | $0.00278 |
Grade A, and why
popups 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 today.
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.

How it starts
The opening of the file, as written. The whole thing — 454 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
-
Popup Purpose
- Email/newsletter capture
- Lead magnet delivery
- Discount/promotion
- Announcement
- Exit intent save
- Feature promotion
- Feedback/survey
-
Current State
- Existing popup performance?
- What triggers are used?
- User complaints or feedback?
- Mobile experience?
-
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 ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

popups is a skill published in the GitHub repository coreyhaines31/marketingskills (56,921 stars, last pushed today), licensed MIT. It adds 116 tokens to every session and 2,781 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
