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 — 298 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 298 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.

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/

# 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

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 @claude-code-skills.

Do these skills work with OpenAI Codex / Cursor / Windsurf / Aider? Yes. Skills work natively with 11 tools: Claude Code, OpenAI Codex, Gemini CLI, OpenClaw, Cursor, Aider, Windsurf, Kilo Code, OpenCode, Augment, and Antigravity. Run ./scripts/convert.sh --tool all to convert for all tools, then install with ./scripts/install.sh --tool . 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 298 Python CLI tools use the standard library only — zero pip installs required. Every script is verified to run with --help.

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.
