skillkit
By rfxlamia
Create and validate high-quality Claude Code skills using TDD workflow: choose fast/full modes for generation, run behavioral tests, security scans, token estimates, and automated quality gates targeting 9.0/10+ scores. Decide skill vs subagent, migrate docs, get templates and guidance.

Component Details
Skills (3)
Pre-build orientation for skill creators. Answers "what are skills?", "should I make one?", and "is my skill good enough?" before you start building. Use for: understand skills, decide skills vs subagents, validate an existing skill. When ready to actually build, invoke /skillkit directly instead.
One sentence: what this skill does and when to invoke it. Use for: [list 2-3 trigger phrases users would naturally type].
Toolkit for creating and validating skills and subagents. Use when: creating a new skill (fast or full mode), validating an existing skill, deciding Skills vs Subagents, migrating docs to skills, estimating token cost, or running a security scan. Triggers: "create skill", "build skill", "validate skill", "new subagent", "skills vs subagents", "estimate tokens", "security scan".

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 validationskillkit-help— pre-build orientation: understand what skills are, decide skills vs subagents
Looking for community skills & agents? Use:

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

SkillKit Creator Reference
The 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.
