A few nits:

1. Writing code is cheap now

Change to "generating code is cheap", reserve "writing" for the manually written code for the pre-AI era. I think this is a good wording separation.

2. Agentic Engineering Patterns

I must ask to add at least a chapter to be read by agent. I.e., patterns just to tell agents how human might be working when working with them. Without this, I believe the book's content will be less relevant in 3 months, but with that, it feels a agentic-native book to me. (this is not try to be cute, we have to write for agents now)

I kinda feel that this person makes a lot of noise in this website. Can we rate limit them a bit?

Simon, if you're reading this, I'm a huge fan of so much of your work! Rodney CLI has been a game changer for local development. I have a few open PRs that I've contributed but it doesn't look active. Are you planning on maintaining it or should I fork it?

one theory I am thinking through is that people say AI is good at greenfield and has a harder time editing code in a legacy code base.

So maybe you just treat projects as greenfield instead of editing.

Like if you want to make changes to a page you generate a new version of the page instead of editing the old one in place.

Then you keep the old version as fallback if problems come up with the new version.
