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 validationskillkit-help — pre-build orientation: understand what skills are, decide skills vs subagentsLooking for community skills & agents? Use:
npx @rfxlamia/sm→ SkillKit Marketplace
npx @rfxlamia/skillkit
Interactive CLI — pick your tool(s), choose user or project scope. Done.
| 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?" |
npx @rfxlamia/skillkit/skillkit-help — guided path to your first skill in ~10 minutesThe skillkit skill drives the creation workflow:
| Trigger | Workflow | Steps |
|---|---|---|
create skill | Full skill creation | 12 steps with research + validation |
create subagent | Subagent creation | 8 steps with template-based workflow |
validate skill | Validation only | Structure, references, quality checks |
Skills vs Subagents | Decision helper | Recommends approach, then creates |
convert doc to skill | Migration | Transform existing docs into skills |
Quality target: 9.0+/10 via 5-layer validation and multi-proposal generation.
14 Python scripts in skills/skillkit/scripts/ — all support --format {text|json}.
