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 — ~402 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 ~402 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.

Multi-Tool Support (New)

Convert all 156 skills to 7 AI coding tools with a single script:

Tool	Format	Install
Cursor	.mdc rules	./scripts/install.sh --tool cursor --target .
Aider	CONVENTIONS.md	./scripts/install.sh --tool aider --target .
Kilo Code	.kilocode/rules/	./scripts/install.sh --tool kilocode --target .
Windsurf	.windsurf/skills/	./scripts/install.sh --tool windsurf --target .
OpenCode	.opencode/skills/	./scripts/install.sh --tool opencode --target .
Augment	.augment/rules/	./scripts/install.sh --tool augment --target .

Hermes Agent	~/.hermes/skills/	python scripts/sync-hermes-skills.py --verbose

How it works:

# 1. Convert all skills to all tools (takes ~15 seconds)
./scripts/convert.sh --tool all

# 2. Install into your project (with confirmation)
./scripts/install.sh --tool cursor --target /path/to/project

# Or use --force to skip confirmation:
./scripts/install.sh --tool aider --target . --force

# 3. Verify
find .cursor/rules -name "*.mdc" | wc -l  # Should show 156

Each tool gets:

• ✅ All 156 skills converted to native format
• ✅ Per-tool README with install/verify/update steps

Personas

Pre-configured agent identities with curated skill loadouts, workflows, and distinct communication styles. Personas go beyond "use these skills" — they define how an agent thinks, prioritizes, and communicates.

Persona	Domain	Best For
Startup CTO	Engineering + Strategy	Architecture decisions, tech stack selection, team building, technical due diligence
Growth Marketer	Marketing + Growth	Content-led growth, launch strategy, channel optimization, bootstrapped marketing
Solo Founder	Cross-domain	One-person startups, side projects, MVP building, wearing all hats

Usage:

# Claude Code
cp agents/personas/startup-cto.md ~/.claude/agents/

# Any tool
./scripts/convert.sh --tool cursor  # Converts personas too

See agents/personas/ for details. Create your own with TEMPLATE.md.

---

Orchestration

A lightweight protocol for coordinating personas, skills, and agents on work that crosses domain boundaries. No framework required.

Four patterns:

Pattern	What	When
Solo Sprint	Switch personas across project phases	Side projects, MVPs, solo founders
Domain Deep-Dive	One persona + multiple stacked skills	Architecture reviews, compliance audits
Multi-Agent Handoff	Personas review each other's output	High-stakes decisions, launch readiness
Skill Chain	Sequential skills, no persona needed	Content pipelines, repeatable checklists

Example: 6-week product launch

Week 1-2: startup-cto + aws-solution-architect + senior-frontend → Build
Week 3-4: growth-marketer + launch-strategy + copywriting + seo-audit → Prepare
Week 5-6: solo-founder + email-sequence + analytics-tracking → Ship and iterate

See orchestration/ORCHESTRATION.md for the full protocol and examples.

Footnotes

1. Hermes Agent is BYO-sync tier: the repo ships a pre-generated .hermes/skills/claude-skills/ tree (305 skills across 12 domains as of v2.7.3), 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. ↩
