I think one of the main examples that i saw in a swyx article a while back is that using the sort of ALL CAPS and *IMPORTANT* language that works decently with claude will actually detune the codex models and make them perform worse. I will see if I can find the post
Because that just does it for you, it doesn't help me understand how to write better prompts.
Actually, I can just read the skill with my own eyes and then I can also learn. So, thank you for sharing. It's interesting to read through what it suggests for different models - it fits for the ones I work with regularly, but there are many I don't know the strengths and weaknesses of.
Would also be interested in examples of a CLAUDE.md file that works well in Claude, but works poorly with Codex.
