Brainstorm Experiments New
Turn a new product idea into XYZ hypotheses and low-effort pretotype experiments before you commit engineering time.
Overview
Brainstorm-experiments-new is an agent skill most often used in Validate (also Idea) that designs XYZ hypotheses and pretotype experiments for new products with minimal effort.
Install
npx skills add https://github.com/phuryn/pm-skills --skill brainstorm-experiments-newWhat is this skill?
- Produces XYZ hypotheses: at least X% of Y will do Z
- Suggests 2–3 pretotype experiments per concept with minimal effort
- Covers landing pages, explainer video, email, pre-order/waitlist, and concierge MVP options
- Reads user-supplied market research or mockups when provided
- Grounded in lean startup / Alberto Savoia-style pretotyping principles
- 2–3 pretotype experiments suggested per validation pass
Adoption & trust: 1k installs on skills.sh; 12.3k GitHub stars; 3/3 security scanners passed (skills.sh audits).
What problem does it solve?
You have a new product concept but no cheap, structured way to test whether anyone in your target market will actually engage.
Who is it for?
Solo founders choosing what to build next who want landing-page or waitlist tests instead of guessing demand.
Skip if: Mature products optimizing funnels—use growth experiment skills—or when the spec is already approved and you only need an implementation plan.
When should I use this skill?
Validating a new product idea, creating pretotypes, or testing market demand.
What do I get? / Deliverables
You leave with an XYZ hypothesis plus 2–3 concrete pretotype plans you can run before writing production code.
- XYZ hypothesis statement
- 2–3 pretotype experiment briefs with methods and success signals

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Validate because the skill designs market tests for ideas that are not built yet. Scope fits framing who will do what (X% of Y will Z) and choosing the smallest experiments to learn.
Where it fits
Compare two audience segments by drafting different Y markets inside XYZ hypotheses before picking a niche.
Turn a one-line product pitch into measurable Z behaviors and pick landing page versus concierge pretotypes.
Specify a landing-page experiment with sign-up success criteria tied to the X% threshold in your hypothesis.
Pause engineering until pretotype results exist—reuse the skill to add a pre-order test if the first pretotype is inconclusive.
How it compares
Lean pretotype designer for new ideas, not a full analytics stack or A/B platform integration.
Common Questions / FAQ
Who is brainstorm-experiments-new for?
Indie PMs and solo builders validating greenfield ideas who want structured pretotypes instead of open-ended brainstorming alone.
When should I use brainstorm-experiments-new?
In Validate scope when defining XYZ hypotheses and pretotypes; in Idea research when comparing concepts; before Build when you still need proof of demand via landing page or waitlist tests.
Is brainstorm-experiments-new safe to install?
It is planning prose with no shell requirements by default; review the Security Audits panel on this Prism page for the pm-skills package source.

## Design Lean Startup Experiments (New Product) Create XYZ hypotheses and design pretotype experiments to validate a new product concept with minimal effort. ### Context You are helping validate a new product concept: **$ARGUMENTS** using lean startup methodology. If the user provides files (market research, landing page mockups), read them first. ### Instructions 1. **Create an XYZ Hypothesis** in the form: "At least X% of Y will do Z" - **X%**: The percentage of the target market expected to engage - **Y**: The specific target market (e.g., "mid-size luxury sedan buyers") - **Z**: How they will engage with the product 2. **Suggest 2-3 pretotype experiments** to test the hypothesis with minimal effort. Consider: - **Landing Page**: Test interest by measuring sign-ups or clicks - **Explainer Video**: Test understanding and appeal through engagement metrics - **Email Campaign**: Test demand through response and click-through rates - **Pre-Order / Waitlist**: Test willingness to pay through skin-in-the-game commitment - **Concierge / Manual MVP**: Deliver the service manually to test value 3. **Key principles** (Alberto Savoia, *The Right It*): - **Skin-in-the-Game**: Test willingness to pay — not just interest. Real commitment (time, money, reputation) is the only reliable signal. - **Your Own Data (YODA)**: Collect your own data through experiments rather than relying on Others' Data (ODP) like market reports or analogies. "The market for your idea does not care about the market for someone else's idea." - Measure actual behavior, not users' opinions 4. **For each experiment**, specify the hypothesis being tested, the method, the metric, and the success threshold. Think step by step.
