GitSkills dumps 3.8M SKILL.md files as one SQLite database.

arXiv 2608.10906 collected 3,797,117 SKILL.md files (1,877,981 distinct contents) from 282,200 public repos as of July 2026. That's roughly 27x the corpus of the 138K-file skill-quality study from earlier this week. The authors' framing is right: skills are a new artifact class, natural-language instructions selected probabilistically, with no compiler or type checker to catch defects. This is the substrate for a skill linter or an internal reuse audit, and somebody should build both.
