I see the same thing and have effectively the same philosophy. If I'm using something like figma or glean or playwright/chrome dev tools, plugin/skill/mcp - likely very useful.
But so many of the weird collections of skills that people on YouTube get viral followings for - I just don't get it.
People excitedly ask me what skills I use and I feel bad just saying only things we've directly authored for some express purpose. None of the "hot" ones.
I've written a large handful of skills, but they aren't like vim plugins. I don't just leave them "on".
This has been my experience at least- curious if I'm just behind the times.
I also effectively didn't leave the IDE+ChatGPT copy/paste workflow until the first release of Claude code. So maybe I'm slow to adopt.
