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
