Product
A SKILL.md file that automates one specific repeatable business task. Best current niches on Agensi: SEO keyword research workflows, B2B cold email sequences, Etsy listing generation (meta: this pairs directly with Product 2), product description generation for Shopify. Pick one you can test and iterate.
What a Skill is
A structured markdown file with system instructions, step-by-step agent logic, input/output format definitions, and quality checks — essentially an AI agent blueprint that any compatible tool can run. It's portable (not locked to one AI model) and permanent (buyers own it).
AI Stack
Claude to design and write the SKILL.md logic
ChatGPT to test the skill from a buyer's perspective
Agensi as the marketplace (agensi.io)
Markdown editor (Obsidian or VS Code) for formatting
Validation
Before building: search Agensi for your intended niche. If fewer than 5 skills exist, proceed. If 20+ exist, find a sub-niche or different task. Test your skill yourself on 3 different real-world inputs before listing. Poor output quality = bad reviews = death on a small platform.
Timeline
Day 1: choose niche + study top 5 Agensi listings. Day 2–3: design skill logic with Claude. Day 4: testing and iteration. Day 5: write listing copy. Day 6: submit to Agensi (8-point security review before publishing). Day 7–10: first sale possible through organic search.
Income math
$8 × 89 installs = $712 gross. At 70% revenue share: $498 net — from one file, once built. The platform is early enough that 89 installs in a month is achievable for a quality skill in an underserved niche. Top 3 skills on the platform are doing this. This is not typical — but it is the documented current ceiling for early movers.
