Joel Spolsky represents one of the most distinctive thinking patterns in their field. Joel Spolsky's approach — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The developer experience & the joel test framework distils Joel Spolsky's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds. Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Joel Spolsky made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Joel Spolsky's distinctive patterns rather than a default model voice.

Inside the framework

A glimpse of Joel Spolsky's thinking.

Core Philosophy

Great software comes from removing friction for developers—give them the best tools, eliminate interruptions, and create systems that make the right thing the easy thing. Most software failures aren't technical; they're organizational failures that manifest as technical problems.
