What Are Skills?
Skills are modular instruction packages that give AI coding agents domain expertise they don't have out of the box. Each skill includes:
- SKILL.md — structured instructions, workflows, and decision frameworks
- Python tools — 254 CLI scripts (all stdlib-only, zero pip installs)
- Reference docs — templates, checklists, and domain-specific knowledge
One repo, eleven platforms. Works natively with Claude Code, and converts to 10 other tools via scripts/convert.sh. All 254 Python tools run anywhere Python runs.
Skills vs Agents vs Personas
| Skills | Agents | Personas | |
|---|---|---|---|
| Purpose | How to execute a task | What task to do | Who is thinking |
| Scope | Single domain | Single domain | Cross-domain |
| Voice | Neutral | Professional | Personality-driven |
| Example | "Follow these steps for SEO" | "Run a security audit" | "Think like a startup CTO" |
All three work together. See Orchestration for how to combine them.
