"Writing code is cheap now" talks about the central challenge of agentic engineering: the cost to churn out working code has dropped to almost nothing, how does that impact our existing intuitions about how we work, both individually and as a team? https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/

"Red/green TDD" talks about how you can get much better results from most coding agents by encouraging them to use test-first development where they watch the tests fail before building an implementation that lets them pass https://simonwillison.net/guides/agentic-engineering-patterns/red-green-tdd/
