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 — 706 CLI scripts (all stdlib-only, zero pip installs)
• Reference docs — 823 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 727 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.

Quick Install

Windows users: clone with git clone -c core.symlinks=true (Developer Mode enabled) — otherwise the .gemini//.codex//.vibe//.hermes/ mirror trees check out as 1-line pointer text files instead of skills — and set PYTHONUTF8=1 so tools that print Unicode don't crash on legacy-codepage consoles. Details: INSTALLATION.md → Windows Notes.

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.

FAQ

How do I install Claude Code plugins? Add the marketplace with /plugin marketplace add alirezarezvani/claude-skills, then install any skill bundle with /plugin install <name>@claude-code-skills.

Do these skills work with OpenAI Codex / Cursor / Windsurf / Aider / Mistral Vibe? Yes. Skills work natively with 13 tools: Claude Code, OpenAI Codex, Gemini CLI, OpenClaw, Hermes Agent, Mistral Vibe, Cursor, Aider, Windsurf, Kilo Code, OpenCode, Augment, and Antigravity. Hermes Agent and Mistral Vibe both use the same agentskills.io SKILL.md standard — run python scripts/sync-hermes-skills.py or ./scripts/vibe-install.sh to install. For other tools run ./scripts/convert.sh --tool all then ./scripts/install.sh --tool <name>. See Multi-Tool Integrations for details.

Will updating break my installation? No. We follow semantic versioning and maintain backward compatibility within patch releases. Existing script arguments, plugin source paths, and SKILL.md structures are never changed in patch versions. See the CHANGELOG for details on each release.

Are the Python tools dependency-free? Yes. All 727 Python tools use the standard library only — zero pip installs required. Every skill's CLI entry point is verified to run with --help (most skills ship one script per tool; a few, like the vendored engineering/skillopt-sleep engine, ship a multi-module package behind a single python -m entry point). A few tools — engineering/book-to-skill's document extractors — can optionally use third-party parsers for higher-fidelity output, but every format falls back to a standard-library parser and nothing is installed implicitly.

How do I create my own Claude Code skill? Each skill is a folder with a SKILL.md (frontmatter + instructions), optional scripts/, references/, and assets/. See the Skills & Agents Factory for a step-by-step guide.

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. ↩
