One of the weirder things in "AI" is the whole "skills" thing. It sounds as if those were somehow little programs or tools integrated into your agents but they are just markdown files with strings that you pull into your prompt to hope the slop machine does better. Crazy shit.
@tante skills are just macros.

@tante as I noted, “skills are just macros”, but I guess they’re a little cleverer than that.

They work-around limited context space by being part of your prompt that only gets loaded if the skill-triggering metadata indicates the “skill” may be relevant to the problem at hand.
