Skill Files Are the New Free Courses: $500 Expert Tutorials Now Exist as Markdown on GitHub
heyneighbor · x · 2026-11-11
0xDesigner points out one of AI's most overlooked upsides: skill files written for agents are also readable by humans. A few years ago you'd pay hundreds of dollars for a course from "a guy in a rented lambo" — now the same knowledge sits in a free markdown file on GitHub. "You can just learn things."
The observation highlights an unexpected dividend of the coding-agent ecosystem: structured, executable documentation built for agents doubles as high-quality human tutorials, quietly replacing a slice of the paid-course market.
