Example: I'm building a music player in Swift for MacOS. I want to have visualizers that use Metal to render directly with the GPU. I don't understand GPU rendering. I never will. So, what do I do?
I tell a strong model like Opus or Fable to write a spec first. Tell it that I want "lesser/cheaper models" to be able to do the actual implementation without needing to guess or think too hard about it. It builds something exactly like this: https://github.com/bocan/bocan-music/blob/main/docs/design-s...
As you can see, I don't just tell it to build software. I tell it to build tests. My CLAUDE.md has guardrails. It knows that if it's told to build anything, it has to format, lint, run the new tests and old tests. It knows to keep my coverage above 80%. When it's done, it commits with a highly detailed commit message.
When all that's done. I test the software extensively by hand. Does it do exactly what I want? If so, great. Next feature. If not, I go back and have my lesser/cheaper model fix the code and add tests. I rarely if ever update the specs if it finds bugs as there's no need.
