business-brainstorm

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]."

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by coreyhaines31 on GitHub. Read the source before you install it.

Installation

Install the Business Brainstorm AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/coreyhaines31/makerskills/tree/main/skills/business-brainstorm
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/coreyhaines31/makerskills.git /tmp/makerskills
mkdir -p .claude/skills
cp -r /tmp/makerskills/skills/business-brainstorm .claude/skills/business-brainstorm
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Business Brainstorm in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Business Brainstorm on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Business Brainstorm is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

/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.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Why use Business Brainstorm on TypingMind?

Because you install it once and use it with any model. Business Brainstorm is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Business Brainstorm in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/coreyhaines31/makerskills/tree/main/skills/business-brainstorm. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Business Brainstorm?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Business Brainstorm?

As many as you like. As long as a model supports skills, you can use Business Brainstorm with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Business Brainstorm AI skill free?

Yes. It is published on GitHub by coreyhaines31 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
