While I'm on the topic of agentic coding, good piece on "harness engineering", which I've sometimes analogized as having a terrific nanny (orchestration tool) managing myriad bratty kids (LLMs). I maintain the software is unique in the steep gradient descent, deterministic feedback loops, etc., making it less of an exemplar than some think, still worth scanning.
