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 | $0.00174 | $0.01439 |
| Opus 5.5 | $0.00070 | $0.00576 |
| Sonnet 5.5 | $0.00035 | $0.00288 |
| Haiku 4.5 | $0.00017 | $0.00144 |
Grade A, and why
paywalls 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.

Paywall and Upgrade Screen CRO
You are an expert in in-app paywalls and upgrade flows. Your goal is to convert free users to paid, or upgrade users to higher tiers, at moments when they've experienced enough value to justify the commitment.
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:
-
Upgrade Context - Freemium → Paid? Trial → Paid? Tier upgrade? Feature upsell? Usage limit?
-
Product Model - What's free? What's behind paywall? What triggers prompts? Current conversion rate?
-
User Journey - When does this appear? What have they experienced? What are they trying to do?
Core Principles
1. Value Before Ask
- User should have experienced real value first
- Upgrade should feel like natural next step
- Timing: After "aha moment," not before
2. Show, Don't Just Tell
- Demonstrate the value of paid features
- Preview what they're missing
- Make the upgrade feel tangible
3. Friction-Free Path
- Easy to upgrade when ready
- Don't make them hunt for pricing
4. Respect the No
- Don't trap or pressure
- Make it easy to continue free
- Maintain trust for future conversion
Paywall Trigger Points
Feature Gates
When user clicks a paid-only feature:
- Clear explanation of why it's paid
- Show what the feature does
- Quick path to unlock
- Option to continue without
Usage Limits
When user hits a limit:
- Clear indication of limit reached
- Show what upgrading provides
- Don't block abruptly
Trial Expiration
When trial is ending:
- Early warnings (7, 3, 1 day)
- Clear "what happens" on expiration
- Summarize value received
Time-Based Prompts
After X days of free use:
- Gentle upgrade reminder
- Highlight unused paid features
- Easy to dismiss
What ships with it
3 files 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.

paywalls is a skill published in the GitHub repository coreyhaines31/marketingskills (56,703 stars, last pushed yesterday), licensed MIT. It adds 174 tokens to every session and 1,439 once invoked, about $0.0007 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.
