Just is a command runner like make but with cleaner syntax, and this skill helps Claude write justfiles with proper structure. It covers the essentials: recipe attributes for confirmation prompts and OS restrictions, the arg system for CLI-style flags (added in v1.46), built-in constants for terminal colors, and module imports. The quick reference tables are genuinely useful since Just's attribute system has grown complex over recent versions. If you're using Just for task automation and want Claude to generate recipes that follow current patterns, including check/write workflows and proper shell settings, this gets you there. The skill requires unstable features enabled for modules and user-defined functions, so keep that in mind.
