About

Keep What Works is one writer's working notebook made public: essays on building durable systems, written from inside the work rather than above it. The essays share a spine — twelve principles, each earned by something breaking — and the site keeps them honest with executable checks: claims trace to instruments, numbers trace to measurements, and a test suite reds when the copy outruns the evidence.

The tool that fell out of writing them is Trinity Local: send one prompt to Claude, ChatGPT, and Gemini in parallel, see what they agree on and where they split, and let a chairman synthesize a verdict weighted by which model your own decisions historically side with. It is free, MIT-licensed, local-first, and runs on the subscriptions you already pay for. No lab can build it, because no lab can see across all three — that asymmetry is the whole idea, and the essays explain why.

The name is the method: throw what breaks, keep what works, and make "works" mean something you can measure. The essays are the long version. The story is the short one.
