CLI Development

This skill grounds CLI work in the Command Line Interface Guidelines — an open-source guide maintained by Aanand Prasad, Ben Firshman, Carl Tashian, and Eva Parish that updates traditional UNIX principles for modern human-first command-line tools.

clig.dev is a single canonical page. The full text is published under https://clig.dev/ (HTML) and https://clig.dev/llms.txt (machine-readable markdown). This skill mirrors the structure of that guide as a sitemap plus per-section reference files, and instructs you to fetch the canonical source before citing rules so your recommendations track upstream changes.
