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 — 305 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 305 Python tools run anywhere Python runs.

Skills vs Agents vs Personas

All three work together. See Orchestration for how to combine them.
