The Field Guide is the short version of The 90% Code — the thesis, the framework, and the questions worth starting with. It reads as an interactive guide now, so it works just as well on your phone as on your laptop. Prefer a file? There's a Download PDF option inside.

It's the entry point, not the whole tool — but it's enough to start seeing your own system clearly.

The book lands October 2026. There's a link inside to join the launch list, if you want the Prelude and Chapter 1 before then.

Best,

Sonali Sharma
