Business Brainstorm (Idea Pressure-Test)

Runs a rough business idea through a 9-dimension founder filter and returns a viability brief with a clear build / sleep / pass verdict.

UtilitiesIntermediate★ 556⑂ 46AI score 7/10Last updated: Aug 1, 2026

What it does

Turns a vague business, product, or side-project idea into a structured viability brief.

Captures the idea in 1–2 sentences plus the "why now"; if it's too vague to score, it asks clarifying questions instead of padding with assumptions.
Scores nine dimensions — problem, audience, wedge, monetization, moat, portfolio fit, distribution, energy fit, opportunity cost — each marked ✅ / 🟡 / ❌ / ❓.
If two or more dimensions are unknown, it offers to run deep-research on market size, competitors, ICP signal, or pricing benchmarks.
Checks .com availability for working names via /domain, and can brainstorm 5–10 candidates.
Outputs a brief with verdict, MVP sketch, first-100-customers plan, open questions, and an "angle to steal" section for killed ideas — then archives it to ~/.config/makerskills/business-brainstorm/archive/ with an INDEX.md entry.

Who it's for

Founders and solo makers with more ideas than time who need a forcing function to decide.
Operators running a portfolio of products who must check overlap and opportunity cost before starting anything new.
Anyone who wants killed ideas documented so they don't get re-litigated months later.

Example uses

"Should I build an invoicing SaaS for freelance designers?" → moat ❌, distribution ✅ → verdict: Sleep on it, with a 30-day revisit reminder.
"Pressure-test a sponsor-matching marketplace for newsletters" → market size and ICP come back ❓ → deep-research runs, findings fold into the brief, plus available .com candidates.
A Pass verdict still yields the "angle to steal" section, which becomes a new feature or offer for an existing property.

Install the skill I found on Claude Skill Mart.

Install with a command instead

git clone https://github.com/coreyhaines31/makerskills.git && mkdir -p ~/.claude/skills && cp -r makerskills/skills/business-brainstorm ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

Open a terminal (Terminal on macOS/Linux, WSL or Git Bash on Windows).
Clone the repo: git clone https://github.com/coreyhaines31/makerskills.git
Create the skills folder: mkdir -p ~/.claude/skills
Copy the skill: cp -r makerskills/skills/business-brainstorm ~/.claude/skills/ — confirm the bundled references/framework.md came along.
Optional: copy the companion deep-research and domain skills the same way so the research and naming steps work end to end.
