What Are Claude Code Skills & Agent Plugins?
Claude Code skills (also called agent skills or coding agent plugins) 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 — 268 CLI scripts (all stdlib-only, zero pip installs)
- Reference docs — templates, checklists, and domain-specific knowledge
One repo, eleven platforms. Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, and converts to 8 more tools via scripts/convert.sh. All 268 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.
