That said, performance and security considerations can be automated by a reusable harness and I think within six months it will just be built in to things like claude code and codex the same way you might tack on a performance/security section to your project's AGENTS.md.

A crude example is how, when building a large forum project years ago, I had a checklist I ran on every new http route: authentication, authorization, validation, etc. just because it's trivial to forget one of them. Yet now the LLM can come up with a lintable/verifiable way to ensure every route has the whole kit by construction.

Almost every way I feel like I can provide unique value to the automated AI workflow (aside from deciding what to build at all, and taste) feels like it can be automated by better markdown.
