I ran a Gumroad store with Claude Code skills — here are 3 of them, free

Description and use

Creating and selling digital products on Gumroad using Claude Code skills in two weeks.

Problem

Create and sell digital products on Gumroad efficiently using Claude Code skills.

Outcome

Generated two Gumroad products with verified formulas and listings in two weeks, leveraging Claude Code skills for automation.

Workflow

• Define a skill folder with SKILL.md and place it in ~/.claude/skills/
• Create skill 1: invoice-generator to auto-generate .xlsx invoices with formulas and verification
• Create skill 2: gumroad-listing-writer to pull product file stats and generate compliant listings
• Create skill 3: cold-email-from-url to generate outreach emails
• Clone the skill repository from GitHub and copy skills into ~/.claude/skills/
• Run the skills via Claude to produce products and listings
• Publish products on Gumroad
• Promote via article

Evidence

Two weeks ago I had zero digital products. Today there are two on Gumroad — an Indonesian freelancer tax tracker (6 sheets, 4,942 formulas) and a photographer booking pack (7 sheets, 2,797 formulas) — plus the listings and the article that promote them. Claude Code did almost all of it.

A skill is a folder with a SKILL.md file. The front matter tells Claude when to use it; the body tells it how. Drop it in ~/.claude/skills/ and Claude picks it up by itself when your request matches.

The helper that does the heavy lifting is ~60 lines: ... print(count_formulas(p)) # 5

The rule that matters: open the product file first and pull real counts. Sheet names, formula counts, page counts. Then write name (≤60 chars), slug, 140-char summary, a sectioned description...
