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 validation, and outputs a viability brief: build / sleep on it / pass. Archives every idea to ~/.config/makerskills/business-brainstorm/archive/ so past work is searchable. Triggers on "/business-brainstorm," "/brainstorm," "new business idea," "should I build X," "pressure test this idea," "validate this idea," "is X a good business," "what about a [type] for [audience]."

/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)
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.
Step 2 — Load the framework + personal overlay
Read references/framework.md — the user's filter. Apply each dimension in order.
Also try to load ${MAKERSKILLS_CONFIG:-$HOME/.config/makerskills}/business-brainstorm/portfolio.local.md if it exists — this is where the user lists their real in-flight businesses, properties, audiences, and partners. When present, use it for the "portfolio fit," "distribution," and "opportunity cost" dimensions instead of asking the user to name each one.
Step 3 — Score each dimension
For each of the 9 dimensions in framework.md, give a 1-line take + a verdict (✅ strong / 🟡 OK / ❌ weak / ❓ unknown — needs research).
Don't BS the unknowns. Mark them ❓ and route to deep-research in Step 4.
Step 4 — Trigger research where needed (optional)
If 2+ dimensions are ❓ unknown, offer the user: "Want me to run /deep-research on [topic] before scoring?"
Useful research targets:
- Market size / who pays signal →
/last30days <space>+WebSearch - Competitive landscape → search for "alternatives to X", "X vs Y" pages
- ICP signal → forums / Reddit / X where the audience hangs out
- Pricing benchmarks → look at competitor pricing pages
If the user says yes, run Skill({skill: "deep-research", args: "<topic>"}) and incorporate the brief.
Step 5 — Check the .com
Always run /domain on the working name(s). A perfect idea with a $50k domain is a worse idea than a B+ idea with a free .com.
If naming is wide open, brainstorm 5–10 candidate names through /domain and report which are available.
Step 6 — Output the brief
Use this template:
# Business brainstorm: <name or idea slug>
**Date:** <YYYY-MM-DD>
**Idea:** <1–2 sentences>
**Why now:** <1 sentence>
## Verdict
**Build** / **Sleep on it** / **Pass** / **Steal an angle for [existing property]**
<2–3 sentence rationale>
## Score
| Dimension | Take | Verdict |
|---|---|---|
| 1. Problem | … | ✅ |
| 2. Audience | … | 🟡 |
| 3. Wedge | … | ❓ |
| 4. Monetization | … | ✅ |
| 5. Moat | … | ❌ |
| 6. Portfolio fit | … | ✅ |
| 7. Distribution | … | ✅ |
| 8. Energy fit | … | 🟡 |
| 9. Opportunity cost | … | ❌ |
## Domain
- <name>.com — available / taken / aftermarket $<price>
- (other candidates if relevant)
## Research applied
- <link to deep-research brief in ~/.config/makerskills/deep-research/archive/, if run>
## Open questions
- <what would change the verdict>
## If you build it (sketch)
- **First 100 customers:** <how>
- **Wedge offer:** <what>
- **Price:** <range>
- **MVP scope:** <1–3 features>
## If you don't build it
- **Angle to steal for existing properties:**
- Property A: …
- Property B: …
- Property C: …
- (etc., only where relevant)
Step 7 — Archive
Archives live in ${MAKERSKILLS_CONFIG:-$HOME/.config/makerskills}/business-brainstorm/archive/ (create the directory if missing). Never write archives inside the skill's own folder — skill installs and upgrades re-sync from source and wipe anything saved there. Migration: if this skill's folder contains an old references/ideas-archive/ with user entries, move those files into the archive directory first.
Write to <archive dir>/<YYYY-MM-DD>-<slug>.md. Append to <archive dir>/INDEX.md (create if missing):
- 2026-06-16 — [<idea>](./<filename>.md) — **<verdict>** — <one-line rationale>
Step 8 — Surface
Show the brief in chat. Tell the user the archive path. Offer:
- "Want to push to Notion as a positioning canvas?"
- "Want me to scaffold a project repo / landing page?" (if verdict = Build)
- "Want me to revisit in 30 days?" (if verdict = Sleep on it)
Composes with
deep-research— for market validation when dimensions are ❓/domain— for .com availability and naming brainstorm/last30days— for audience/market recency signal (via deep-research)- Memory (
project_*.md) — for portfolio context (don't pitch an idea that already exists)
Notes on quality
- Nine dimensions, not one hero metric. Ideas fail because one dimension quietly rots even when the rest score high. Force each dimension to be scored — no "we'll figure that out later" cop-outs.
- Verdict discipline: Ship / Sleep on it / Kill. Not "maybe." Ambiguity in the verdict compounds into ambiguity in the commit; the brief exists to prevent that.
- Portfolio-context check is non-negotiable. Before writing, grep memory + wiki for existing property overlap. If the new idea is 80% one of your existing properties, propose extending the existing property instead of forking a new one — 4x cheaper to compound.
- Archive every brief, even Kills. Killed ideas resurface — the brief with rationale prevents re-litigating. The archive dir + INDEX.md makes revisit trivial.
- "Angle to steal" section forces value from Kills. Even ideas you won't build often have an angle that improves an existing property. Don't skip this section — it's the highest-leverage output of a Kill verdict.
- 30-day revisit for "Sleep on it." Set the calendar reminder. Sleep-on-it ideas that never get revisited become dead weight in the archive; ideas that get revisited resurface with better context.
