This is pushed by Antropic, OpenAI doesn't seem to care much about "skills". Maybe Anthropic is doing some extra training to better follow sections of text marked as skill, who knows? Or you can just store what worked as a skill and share with others without any need to do their own prompt for common tasks?

		Yeah but this seems like a bolt-on and not something they train their model to understand at the token level like how they do tool calls. Maybe Anthropic has a token-level skills support (e.g. <SKILL_START>skill prompt<SKILL_END>).
