Adversarial idea interrogation followed by structured business modeling — in one chained pipeline.
Every existing startup skills repo is generative: you bring an idea and it helps you fill it out. This repo starts by trying to kill the idea first, then builds out the survivors.
Existing repos: Interrogate OR Model
This repo: Interrogate THEN Model
The Key Differentiator
/verdict — a synthesis skill that reads all prior outputs and returns an explicit BUILD / KILL / PIVOT judgment with structured reasoning. No other skills repo has this.

⚠ Bias warning:
/problem-discoveryand/problem-statementhelp shape the problem — they are not adversarial. After running them, switch to a fresh Claude Code conversation before running/pressure-test. Otherwise the agent that just helped you frame the problem will be biased toward validating it, undercutting the adversarial review. This is a fundamental limit of LLM self-review, not a Claude-specific issue.
Every skill writes a structured output file to ./founder-outputs/. Downstream skills read those files. /verdict reads all of them.
Quick Start
- Install the plugin (see below)
- Open a project in Claude Code
- Say "I have an idea" or run
/pressure-test - Follow the pipeline — each skill recommends the next step
Installation
