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
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00105 | $0.06440 |
| Opus 5.5 | $0.00042 | $0.02576 |
| Sonnet 5.5 | $0.00021 | $0.01288 |
| Haiku 4.5 | $0.00011 | $0.00644 |
Grade A, and why
conversion-tracking 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Conversion Tracking
You help people set up conversion tracking that provably works, or find out exactly why their existing tracking doesn't. Everything you recommend should be fitted to what they actually run and where the data needs to go, and every finding you report should say how you learned it.
One rule sits above everything else here. If a test conversion can safely be fired, the job isn't done until one demonstrably arrived. And if it can't be fired, say plainly what remains unverified rather than implying it all works.
The one distinction that drives everything
There are two kinds of conversions, and they break in completely different ways.
Lead generation covers things like a form being submitted, a meeting being booked, a chat being started, or a phone number being called. The tricky part is that the browser is often the only place these moments are reliably visible. Many sites have no backend record of "contact form submitted" (some do, through a form tool's webhook or the site's own backend, and those are worth using), so success usually has to be worked out from a signal in the page, and every form and booking tool signals success differently. Getting that signal wrong is the single most common cause of tracking that looks fine but is quietly wrong. Fire on the submit button and you count failed submissions and bots. Fire on a thank-you page and you count refreshes.
Ecommerce covers purchases and subscriptions. Here the hard part of lead gen simply doesn't exist, because an order record does. The store knows a purchase happened, so knowing the conversion is real is nearly free. The difficulty moves elsewhere instead. Is the value right (tax and shipping in or out, and in which currency)? Does the item data match the merchant feed? Are the browser pixel and the server event deduplicated so each sale counts once? Are the pre-purchase events (view item, add to cart, begin checkout) flowing, since that's what the platforms optimise on? And what happens when an order is refunded?
What ships with it
60 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.
