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 2 weeks via Claude Code + Codex using test suite + human-directed architecture + hundreds of small prompts), we now have both theory and proof. Action: Read Willison's guide. Adopt TDD for all agent-assisted development. Humans define WHAT, agents implement HOW.
