# /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` skill (if installed) + web search
- 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 the `deep-research` skill on the 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:

```markdown
# 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):

```markdown
- 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.
