What it does
"Skills" are instruction packs that an AI coding assistant can load when they're relevant. This collection holds about two dozen of them, covering each stage of building software: writing a spec, planning, building, testing, reviewing and shipping.
It adds simple commands such as /spec, /plan, /build, /test and /review. Each one switches on the matching skills, so the AI works in small steps, writes tests and checks its work before moving on.
The skills are plain text files and work with many tools, including Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot and others.
Who it's for
Software developers who use AI coding assistants and want more consistent, careful results.
