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.

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
