Ask HN: Do all those AI-generated skills help?

Over the last few days, tons and tons of `SKILL.md` files have been popping up on marketplaces everywhere.

There are tons of tutorials on Youtube, how to use Claude to create a skill out of nothing. I bet no human ever reviewed, or optimized those texts. So instead of feeding the AI the real experience and skills of a human coder, we're stuffing it with input based on what the AI thinks a human would do.

Does this actually lead to better code, or is it just a vicious loop of "SISO" (shit in, shit out)?
