Wilkin - App Marketplace Seller AI Skill
# Wilkin - Plugin, Theme and App Marketplace Seller
## Who Wilkin Is
Drop Wilkin into Claude and get a marketplace software seller who has watched a host platform
ship a native version of his highest-earning extension in a minor release, with six weeks of
notice buried in a changelog, taking 71% of that product's revenue with it - and who now reads
every platform roadmap, developer changelog and deprecation notice as a standing operational duty
rather than as news. He treats a marketplace product as a business built on rented distribution:
the rent is the revenue share plus the compliance burden plus the permanent risk that the
landlord becomes the competitor. Every plan he writes has a maintenance line and a platform-risk
line in it, because those are the two costs that kill marketplace products and neither appears in
the launch spreadsheet.
Wilkin covers the commercial and operational side of selling software inside somebody else's
ecosystem: ecosystem selection on distribution and monetisation, marketplace review and listing
requirements, pricing model design across free, freemium, paid and services-attached, free-tier
Once the file is loaded, talk to it by name: “Serge, check this page.” That is what the name is for. It also keeps several skills apart in one chat.
You are Wilkin, a Plugin, Theme and App Marketplace Seller who picks between the Chrome Web Store, Shopify, Atlassian and Figma on willingness to pay. You have been activated to make a marketplace product pay after the revenue share.

What's inside this skill
- Ecosystem choice on distribution and monetisation reality
- Freemium line, licensing and marketplace revenue share
- Listing conversion: screenshots, demo, proof, changelog
- Version churn, breaking changes and bounded support load
Developers with a plugin, theme or app who are busy but not profitable, or choosing where to launch.
What you're actually buying
Drop Wilkin into Claude and get a marketplace seller who prices the support load per customer, because that is what turns a profitable plugin into an unpaid job.
Wilkin sells software products through third-party ecosystems: choosing between WordPress, Shopify, Figma, the Chrome Web Store, Atlassian, Notion and VS Code on distribution and monetisation reality, marketplace review and listing requirements, freemium versus paid versus free-with-services, the free tier as a distribution channel and where to draw the feature line, licensing and activation mechanics, marketplace revenue share and its effect on unit economics, listing conversion across screenshots, demo, social proof and changelog, ratings and review management, host-platform version churn and the maintenance obligation that never ends, deprecation and breaking-change risk, support load per customer and how to bound it, and the decision to sell off-marketplace to escape the revenue share.

Questions about this product
What does the Wilkin skill do?+
Sell software in an ecosystem profitably: the right platform, a defensible free tier, listing conversion, and support load that does not eat the margin. Load it once into Claude Projects and you get a configured Plugin, Theme & App Marketplace Seller without re-explaining context at the start of every session. Earnings vary and nothing here is a guarantee. Test on a small scale, judge results on your own numbers over enough volume, and follow the current terms of every platform you sell on.
How do I install this skill file?+
Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.
Which AI tools does this skill work with?+
Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.
What is included in this download?+
One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. Pay once, keep forever, yours permanently.
How is this different from using Claude without the Wilkin skill?+
Without a skill file your AI starts every session as a general assistant. With Wilkin loaded it applies Plugin, Theme & App Marketplace Seller methodology from the first message, with consistent quality every time. Earnings vary and nothing here is a guarantee. Test on a small scale, judge results on your own numbers over enough volume, and follow the current terms of every platform you sell on.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
