Product Listing Writer Skill

Etsy, Shopify, Amazon and Whop listings, every limit counted

product-listing-writer - findings on the bundled example

One product brief returns listings for 3 stores in one answer: an Etsy title at 121 of 140 characters, 13 tags of max 20, a first line of 143 characters that says the result and the buyer (worked example inside).

Get it on Whop - $19 once Get it on Gumroad

Who it's for

Built for sellers on Etsy, Shopify, Amazon and Whop who write every listing by hand and still get titles cut off or tags rejected.

What breaks, and when

A title over the limit is cut where the store decides, and a first line without the result gives a buyer no reason to open the page.

FAQ

What is a Claude skill?

A folder with a SKILL.md, a method, fill-in templates and a worked example. Claude loads it when your request matches and follows that method instead of improvising.

How is this different from asking Claude without the skill?

The skill carries a fixed method, fill-in templates and a full worked example, so Claude follows the same structure every time instead of improvising a new one.

What does it not do?

It does not upload listings, set prices or invent specs, reviews or sales numbers. Store limits change; if a field is rejected, check the store's help page.
