SkillKit

The toolkit for creating reusable skills for AI coding agents.

SkillKit helps you build, validate, and share skills that extend how your AI agent works. Works with Claude Code, GitHub Copilot, OpenCode, and Codex.

Previously known as claude-skillkit. All old links redirect here automatically.

What is SkillKit?

SkillKit is a toolkit for creating and validating custom AI agent skills. It ships two core skills:

skillkit — meta-skill for creating new skills and subagents with dual-mode validation
skillkit-help — pre-build orientation: understand what skills are, decide skills vs subagents

Looking for community skills & agents? Use: npx @rfxlamia/sm → SkillKit Marketplace

Install

npx @rfxlamia/skillkit

Interactive CLI — pick your tool(s), choose user or project scope. Done.

Core Skills

Skill	Trigger	What it does
skillkit	`/skillkit`	Create & validate skills/subagents — fast mode (12 steps) or full mode (15 steps)
skillkit-help	`/skillkit-help`	Answer "what are skills?", "should I make one?", "is my skill good enough?"

Create Your First Skill

Install: npx @rfxlamia/skillkit
Run /skillkit-help — guided path to your first skill in ~10 minutes
Submit a PR to SkillKit Marketplace to share it
