Use when designing AI agent products, defining roadmaps for agentic workflows, or evaluating how to evolve AI from passive tool to proactive partner in software development

Use when designing AI agents or chatbots, when raw model outputs feel like a black box, or when building natural language interfaces that need structure and trust
Use when building AI-powered products or agents, when raw model intelligence isn't enough to solve user problems, or when designing the architecture for agentic workflows
View yourself as an entity with infinite dimensions rather than a single good/bad identity. Strengths and weaknesses are often the same trait in different contexts. Use during performance reviews or when receiving tough feedback.

| description | Use before starting a company with co-founders, when bringing on a new co-founder, or annually as a relationship health check to prevent the 65% of startup failures caused by co-founder conflict |
A set of critical discussion topics for co-founders to align on before starting a company (or to revisit periodically). Designed to prevent the 65% of startup failures caused by co-founder conflict.
Core principle: Assume nothing. If you act based on your values and they act based on theirs, you'll think they're acting strangely—but they're just being themselves.

Two co-founders realized too late: one wanted a massive venture outcome, the other wanted a small shop where they knew everyone's name. The painful split could have been avoided with this conversation upfront.
