Why data engineering skills work in Codex CLI
Each skill on this page is a SKILL.md file built for data engineering work and confirmed to run in Codex CLI. Install one into ~/.codex/skills/, start a new session, and Codex CLI follows the workflow the creator encoded instead of improvising from a short prompt.
Listings are ranked by installs, upvotes and reviews, so what surfaces first is what other Codex CLI users actually keep. Free and paid skills compete on the same page, and every listing shows its security scan result before you download anything.
