388 production-ready Claude Code skills, plugins, and agent skills for 13 AI coding tools.
The most comprehensive open-source library of Claude Code skills and agent plugins — also works with OpenAI Codex, Gemini CLI, Cursor, and 9 more coding agents. Reusable expertise packages covering engineering, DevOps, marketing (incl. AEO — Answer Engine Optimization for LLM citation), security (PreToolUse hooks), compliance, C-level advisory (incl. founder-mode CFO/CMO/CRO/CPO/COO/CHRO/CISO/GC/CDO/CAIO/CCO/VPE personas + 21 /cs:* slash commands), productivity (capture/email/reflect/weekly-review/deep-work/meetings), an academic research stack (litreview/grants/dossier/patent/syllabus/pulse/notebooklm/deep-research + hybrid router), and enterprise Research Operations (clinical-research/research-finance/market-research/product-research, v2.9.0).
Works with: Claude Code · OpenAI Codex · Gemini CLI · OpenClaw · Hermes Agent[^hermes] · Mistral Vibe[^vibe] · Cursor · Aider · Windsurf · Kilo Code · OpenCode · Augment · Antigravity
[^hermes]: 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.
[^vibe]: 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.
5,200+ GitHub stars — the most comprehensive open-source Claude Code skills & agent plugins library.
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.

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.
