Claude code is Claude code, whether you use in cursor or not

Codex and Claude code are neck and neck, but we made the decision to go all in on opus 4, as there are compounding returns in optimizing prompts and building intuition for a specific model

That said I have tested these prompts on codex, amp, opencode, even grok 4 fast via codebuff, and they still work decently well

But they are heavily optimized from our work with opus in particular
