It is early browser days. It is good they are not converging. That is how we got AJAX (now Fetch) and even JS.
replyIssue is that both harness and specific model matters a lot in what type of instruction works best, if you were to use Anthrophic's models together with the best way to do prompting with Codex and GPT models, you'd get a lot worse results compared to if you use GPT models with Codex, prompted in the way GPTs react best to them.
replyI don't think people realize exactly how important the specific prompts are, with the same prompt you'd get wildly different results for different models, and when you're iterating on a prompt (say for some processing), you'd do different changes depending on what model is being used.
Having experimented with soft-linking AGENTS.md into CLAUDE.md and GEMINI.md, this lines up well with my experience. I now just let each time maintain it's own files and don't try to combine them. If it's something like my custom "## Agent Instructions" then I just copy-pasta and it's not been hard, and since that section is mostly identical I just treat AGENTS.md as the canonical and copy/paste any changes over to the others.

replyAre there any good guides on how to write prompt files tailored to different agents?
replyWould also be interested in examples of a CLAUDE.md file that works well in Claude, but works poorly with Codex.
Why would you settle for a guide when you can get a claude skill to do it for you?
replyBecause that just does it for you, it doesn't help me understand how to write better prompts.
replyActually, 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.
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
replyYou can just use a single agents.md and have claude.md use it. Then symlink or sync skills/etc between .folders. It’s not perfect but works.
replyAgree, for now im using dotagents by sentry to handle a lot of this.
replyAnd why would they ever let switch?
replyInteroperability means that people could switch to them as well
