177 production-ready skills, 16 agents, 3 personas, and an orchestration protocol for 11 AI coding tools.
Reusable expertise packages that give AI coding agents domain knowledge they don't have out of the box — from architecture and security to marketing, compliance, and C-level advisory.
Works with: Claude Code · OpenAI Codex · Gemini CLI · OpenClaw · Cursor · Aider · Windsurf · Kilo Code · OpenCode · Augment · Antigravity
4,400+ GitHub stars — the most comprehensive open-source skill library for AI coding agents.
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 | 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.

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

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?
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 <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 254 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.
We welcome contributions! See CONTRIBUTING.md for guidelines.
Quick ideas:
- Add new skills in underserved domains
- Improve existing Python tools
- Add test coverage for scripts
- Translate skills for non-English markets
