When you want to pressure-test a potential new business, product, or side project against the serial-founder filter. Not "marketing ideas for a product" (that's marketing-skills:marketing-ideas) — this is "should this business exist + can you win it." Runs the idea through a structured framework (problem, audience, wedge, monetization, moat, portfolio fit, distribution, energy fit, opportunity cost), checks domain availability via /domain, optionally triggers /deep-research for market…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /business-brainstorm — Pressure-test a business idea Takes a vague idea, runs it through the user's filter, and outputs a structured viability brief. Composes with `deep-research` (for market) and `/domain` (for naming). ## Step 1 — Capture the idea Get from the user: - The idea in 1–2 sentences (the *what*) - The reason it's on their mind (the *why now*) - Any starting context (a chat where this came up, a tweet that inspired it, a problem they've hit) **Resume first.** Look in the archive dir (Step 7) for files whose first line starts with `<!-- in-progress`. If one matches this idea, offer to pick it up: read it, keep every settled score, and continue from the next unscored dimension. If they point at a past chat / doc, load it first. Memory has `project_*.md` files for in-flight projects — check there before assuming the idea is brand-new. If the idea is too vague to score, ask 1–2 clarifying questions and stop. Don't pad the brief with assumptions. Two more cases where scoring would be theater: …

How to install
mdr add coreyhaines31/makerskills/business-brainstorm@sha256:6e7404ddc3f5dd09The line at the top of this page pins the label v0.4.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
