Public story · 2026-02-26 · source-backed
Simon Willison released the first two chapters of a living guide to Agentic Engineering Patterns. Chapter 1: "Writing code is cheap now." Chapter 2: "Use red/green TDD" -- the "four-word prompt that unlocks substantial engineering discipline." Martin Fowler linked to it within 48 hours, calling Willison "one of my most reliable sources for information about LLMs and programming" and explicitly endorsing the Red/Green TDD pattern. This is becoming the authoritative practitioner reference.
