Business Idea Pressure-Test

Runs a raw business or side-project idea through a 9-dimension founder filter and returns a build / sleep-on-it / pass viability brief.

UtilitiesIntermediate★ 823⑂ 67AI score 9/10Last updated: Sep 4, 2026

What it does

Turns a fuzzy idea into a structured viability brief instead of enthusiastic hand-waving.

  • Scores 9 dimensions — problem, audience, wedge, monetization, moat, portfolio fit, distribution, energy fit, opportunity cost — each marked ✅ / 🟡 / ❌ / ❓
  • Offers to run deep-research when two or more dimensions are unknown
  • Checks .com availability for candidate names via /domain
  • Ends with a hard verdict (Build / Sleep on it / Pass), an MVP sketch, pricing range, first-100-customers plan, and an "angle to steal" section for killed ideas
  • Archives every brief to ~/.config/makerskills/business-brainstorm/archive/ with a running INDEX.md

Who it's for

  • Makers with a constant stream of side-project ideas and no consistent filter
  • Operators running several properties who must decide between launching new vs. extending existing
  • Solo founders who want killed ideas documented so they don't get re-litigated

Examples

  1. "Should I build a contract SaaS for freelance designers?" → scored brief lands on Sleep on it: strong monetization, no moat
  2. "Pressure test this idea" with a link to an old chat → skill loads context, finds 80% overlap with an existing product and proposes an extension instead
  3. Feed it eight name candidates → it runs /domain and reports which .coms are free inside the brief
