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 — 824 CLI scripts (all stdlib-only, zero pip installs)
• Reference docs — 931 templates, checklists, and domain-specific knowledge files

One repo, thirteen platforms. Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, Hermes Agent skills, Mistral Vibe skills, and converts to more tools via scripts/convert.sh. All 824 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.

Footnotes

1. Hermes Agent is BYO-sync tier: the repo ships a pre-generated .hermes/skills/claude-skills/ tree, but you run python scripts/sync-hermes-skills.py once locally to install into ~/.hermes/skills/. Uses the same agentskills.io SKILL.md standard — no format conversion. ↩

2. Mistral Vibe is also BYO-sync tier: the repo ships a pre-generated .vibe/skills/claude-skills/ tree, run ./scripts/vibe-install.sh once locally to install into ~/.vibe/skills/. Same agentskills.io SKILL.md standard — no format conversion. Docs: https://docs.mistral.ai/mistral-vibe/agents-skills. ↩
