Discovery Call Prep
Grounded in The Mom Test and Transformed, this skill turns a hypothesis into a set of discovery-call questions you can actually use. Every question asks about something that already happened, never a hypothetical, and gets tagged with the product risk it tests: value, usability, feasibility, or business viability. It also flags any part of your hypothesis an interview simply can't answer, so you know what still needs a different kind of test. It ends with an ask that costs the person something real, since a real ask is the only signal that tells you whether they meant it.
What it does
Turns a hypothesis about a customer problem into a discovery-call question guide, so every question asks about something that already happened instead of something someone might do.
How to use this
Once it is installed, this skill picks itself up. You do not need to name it.

What this skill does
This is an overview of the skill from the site, not the skill's real instructions. The full SKILL.md Claude reads when this skill is active lives on GitHub at the source below.
Most discovery calls fail quietly. You ask someone whether they’d use a feature, they say “yeah, probably,” and you walk away with a false green light. This skill exists to stop that.
Give it a hypothesis and whatever you know about the person you’re about to talk to, and it builds you a question guide. Every question is written to ask about something that actually happened, not something the person imagines they’d do, because people are bad at predicting their own future behavior and polite about it to your face.
Each question also gets tagged with the risk it’s testing, drawn from Transformed’s four product risks: is this valuable, is it usable, can we build it, does it make business sense. That way you can look at your guide before the call and see if you’re only testing one risk while ignoring the other three.
The guide also tells you upfront what a conversation can’t settle. Some parts of a hypothesis need a prototype, a price test, or a pilot, not an interview, and it’s better to know that going in than to fool yourself with a good-sounding answer.
Finally, it ends every guide with a real ask, something that costs the person time, money, or a next step. If they won’t do it, you’ve learned something more useful than any answer they gave you.
