Your ChatGPT, Claude, and Codex already ship with agent skills, and most people have no idea what those skills are doing to their output. This is what a skill actually is, how to tell a working one from a broken one, and how to build your own.

What's really happening inside agent skills?
The common story is that installing more skills makes your AI more capable. The real question is whether your agent can even see the ones you already have.
In this video, I share the inside scoop on how agent skills actually work:
- Why a folder arriving on your machine proves nothing about your output
- How loading order decides whether your agent ever opens the skill
- What a vague description costs you in wasted context window
- Where conflicts across 25 skills start dulling every result
Skills are the cheapest way to make an agent more useful and the fastest way to make it worse, and what separates the two is whether you ever check what you installed.
