2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 3 stars3 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Test assumptions before committing resources. Generates lean validation plans, fake door tests, and interview scripts. Use before building anything expensive or when there's no evidence anyone wants what's being built.

Market Validation

Test assumptions before committing resources.

How to use

  • /market-validation Apply validation-first constraints to this conversation.
  • /market-validation <idea> Generate a validation plan for the described idea.

Constraints

Assumption Mapping

  • MUST list the top 3 assumptions that would kill the product if wrong
  • MUST rank assumptions by risk: which one, if false, makes everything else irrelevant
  • MUST design a test for the highest-risk assumption first
  • NEVER build until the highest-risk assumption has some evidence behind it

Validation Methods (ordered by speed and cost)

  1. Talk to 5 people who have the problem. Just listen.
  2. Search for existing solutions and read their reviews. What's missing?
  3. Build a landing page that describes the product. Measure interest.
  4. Create a fake door: a button that says "coming soon" to measure demand
  5. Build the smallest possible thing that tests the core assumption

Interview Framework

  • Ask about past behavior, not future intent ("Tell me about the last time..." not "Would you use...")
  • NEVER ask "Would you pay for this?" Ask "How do you solve this today and what does it cost you?"
  • MUST listen for emotion. Mild interest is not validation. Frustration is.
  • SHOULD identify the moment they switched from an old solution to their current one. What triggered it?

Signal vs. Noise

  • "That's cool" is not validation. "When can I use this?" is closer.
  • Email signups are weak signals. Credit card on waitlist is strong.
  • 100 lukewarm responses < 10 people who desperately need this
  • MUST define what "validated" looks like before running the test

Anti-Patterns

  • Survey-based validation (people lie in surveys, even to themselves)
  • Asking friends and family (they'll say what you want to hear)
  • Treating a pitch deck as validation
  • Building first, validating later
  • Validating the easy assumption instead of the risky one

  • test assumptions before committing resources

  • rank assumptions by risk
  • define validation criteria before testing
  • listen for frustration over mild interest

Grouped from the skills themselves: near-identical wordings counted once, and counted by distinct author, so one author publishing three of these counts once. Length counted with cl100k_base; the agent that loads this file may tokenize it differently.
