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.
