Claude Code Skills & Plugins — Agent Skills for Every Coding Tool

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.

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.

Gemini CLI (New)

# Clone the repository
git clone https://github.com/alirezarezvani/claude-skills.git
cd claude-skills

# Run the setup script
./scripts/gemini-install.sh

Multi-Tool Support (New)

Convert all 345 skills to 9 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 . | | Antigravity | ~/.gemini/antigravity/skills/ | ./scripts/install.sh --tool antigravity | | Hermes Agent | ~/.hermes/skills/ | python scripts/sync-hermes-skills.py --verbose | | Mistral Vibe | ~/.vibe/skills/ | ./scripts/vibe-install.sh |

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 346

Each tool gets:

• ✅ All 345 skills converted to native format
• ✅ Per-tool README with install/verify/update steps
• ✅ Support for scripts, references, templates where applicable
• ✅ Zero manual conversion work

Run ./scripts/convert.sh --tool all to generate tool-specific outputs locally.
