simonwillison.net — Willison has been publishing 5-8 posts per day for the last week, and is now consolidating into a structured guide. Two chapters published: "Writing code is cheap now" explores the economic implications when implementation approaches zero marginal cost — the value shifts entirely to judgment, architecture, and specification. "Red/green TDD" documents the workflow that 5+ independent sources have converged on. This is the definitive resource for how to work with coding agents effectively.

Simon Willison launched a multi-chapter guide collecting practical patterns for working with coding agents. Chapters include "Writing code is cheap now," "First run the tests," "Red/green TDD," "Hoard things you know how to do," and the new "Interactive Explanations" chapter f...
Third chapter of Willison's evolving Agentic Engineering Patterns guide (endorsed by Martin Fowler). Core technique: maintain a personal solutions library and feed proven examples to agents for recombination. This joins Red/Green TDD and "Writing code is cheap now" as the thre...
Willison's guide is the closest thing to a consensus playbook for working with coding agents. Two chapters published: "Writing code is cheap now" (the economics shift) and "Red/green TDD" (the methodology). Combined with the Ladybird Rust port case study (25K lines of Rust in...
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...
The fourth chapter of Willison's Agentic Engineering Patterns guide addresses cognitive debt by having agents build interactive animated explanations of their own code. Martin Fowler endorsed the full guide. The methodology is now four chapters: (1) code is cheap, (2) red/gree...
Willison shipped datasette-agent-edit 0.1a0 on June 7, letting agents perform structured data edits inside Datasette, alongside micropython-wasm sandbox work for running untrusted agent code. Separately his evolving Agentic Engineering Patterns guide reframes the work around t...
