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

364 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>.

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* — 667 CLI scripts (all stdlib-only, zero pip installs)
• Reference docs* — 750 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 667 Python tools run anywhere Python runs.

Skills vs Agents vs Personas

All three work together. See Orchestration for how to combine them.

OpenAI Codex

npx agent-skills-cli add alirezarezvani/claude-skills --agent codex
# Or: git clone + ./scripts/codex-install.sh

OpenClaw

bash <(curl -s https://raw.githubusercontent.com/alirezarezvani/claude-skills/main/scripts/openclaw-install.sh)

Manual Installation

git clone https://github.com/alirezarezvani/claude-skills.git
# Copy any skill folder to ~/.claude/skills/ (Claude Code) or ~/.codex/skills/ (Codex)

Multi-Tool Support (New)

Convert all 345 skills to 9 AI coding tools* with a single script:

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.

Skills Overview

364 skills across 18 domains:*

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.

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:*

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.

POWERFUL Tier

25 advanced skills with deep, production-grade capabilities:

🔒 Skill Security Auditor

New in v2.0.0 — audit any skill for security risks before installation:

python3 engineering/skill-security-auditor/scripts/skill_security_auditor.py /path/to/skill/

Scans for: command injection, code execution, data exfiltration, prompt injection, dependency supply chain risks, privilege escalation. Returns PASS / WARN / FAIL* with remediation guidance.

Zero dependencies.* Works anywhere Python runs.

Recently Enhanced Skills

Production-quality upgrades added for:

• engineering/git-worktree-manager — worktree lifecycle + cleanup automation scripts
• engineering/mcp-server-builder — OpenAPI -> MCP scaffold + manifest validator
• engineering/changelog-generator — release note generator + conventional commit linter
• engineering/ci-cd-pipeline-builder — stack detector + pipeline generator
• marketing-skill/prompt-engineer-toolkit — prompt A/B tester + prompt version/diff manager

Each now ships with scripts/, extracted references/, and a usage-focused README.md.

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 667 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.
