About this skill

Claude Skills Library Expert

Skill by ara.so — Claude Code Skills collection.

Expert in using, installing, and contributing to the alirezarezvani/claude-skills repository — the most comprehensive open-source library of AI coding agent skills with 268+ production-ready skills across 9 domains (engineering, marketing, product, compliance, C-level advisory, etc.).

What This Project Does

The claude-skills library provides modular instruction packages (skills) that give AI coding agents domain expertise they don't have out of the box. Each skill includes:

  • SKILL.md — structured instructions, workflows, decision frameworks
  • Python tools — 373 CLI scripts (stdlib-only, zero pip installs)
  • Reference docs — templates, checklists, domain-specific knowledge

Multi-tool support: Works natively with Claude Code, OpenAI Codex, Gemini CLI, and converts to 9+ other tools (Cursor, Aider, Windsurf, Kilo Code, OpenCode, Augment, Antigravity, Hermes Agent).

Converting Skills to Other Tools

The library supports 12 AI coding tools via conversion scripts.

Convert All Skills to All Tools

cd claude-skills
./scripts/convert.sh --tool all

This generates tool-specific outputs in:

  • .cursor/ — Cursor .mdc rules
  • .aider/ — Aider CONVENTIONS.md
  • .kilocode/ — Kilo Code rules
  • .windsurf/ — Windsurf skills
  • .opencode/ — OpenCode skills
  • .augment/ — Augment rules
  • ~/.gemini/antigravity/ — Antigravity skills
  • ~/.hermes/ — Hermes Agent skills

Install Converted Skills into a Project

# Install with confirmation
./scripts/install.sh --tool cursor --target /path/to/project

# Force install without confirmation
./scripts/install.sh --tool aider --target . --force

Tool-Specific Conversion

# Cursor
./scripts/convert.sh --tool cursor
./scripts/install.sh --tool cursor --target .

# Aider
./scripts/convert.sh --tool aider
./scripts/install.sh --tool aider --target .

# Windsurf
./scripts/convert.sh --tool windsurf
./scripts/install.sh --tool windsurf --target .

# Hermes Agent

Using Personas

Personas are pre-configured agent identities with curated skill loadouts and distinct communication styles.

Available Personas

  • startup-cto — Architecture decisions, tech stack, team building
  • growth-marketer — Content-led growth, launch strategy, channel optimization
  • solo-founder — Cross-domain, MVP building, wearing all hats

Install a Persona

# Claude Code
cp agents/personas/startup-cto.md ~/.claude/agents/

# For other tools, convert first
./scripts/convert.sh --tool cursor

Use a Persona

# In your conversation with the AI agent:
"I want you to act as the Startup CTO persona. Review my architecture decisions for this new feature."

Orchestration Patterns

Orchestration coordinates personas, skills, and agents across domain boundaries.

Four Patterns

1. Solo Sprint — Switch personas across project phases

Week 1-2: startup-cto + aws-solution-architect
Week 3-4: growth-marketer + launch-strategy
Week 5-6: solo-founder + analytics-tracking

2. Domain Deep-Dive — One persona + multiple stacked skills

# Example: Security audit
/activate persona startup-cto
/use skill-security-auditor
/use aws-solution-architect
/use compliance-automation

3. Multi-Agent Handoff — Personas review each other's output

1. startup-cto designs architecture
2. devops-engineer reviews deployment strategy
3. skill-security-auditor audits the plan

4. Skill Chain — Sequential skills, no persona needed

# Content pipeline
/use copywriting → /use seo-content-optimizer → /use email-sequence

See orchestration/ORCHESTRATION.md for full protocol and examples.

Common Patterns

Using Python Tools from Skills

All 373 Python tools are stdlib-only and can run anywhere:

#!/usr/bin/env python3
# Example: engineering-team/playwright-pro/scripts/generate-test.py
import sys
import json

def generate_test(page_url, selectors):
    """Generate a Playwright test from URL and selectors."""
    test_code = f"""
import {{ test, expect }} from '@playwright/test';

test('test {page_url}', async ({{ page }}) => {{
  await page.goto('{page_url}');
  await expect(page.locator('{selectors[0]}')).toBeVisible();
}});
"""
    return test_code

if __name__ == "__main__":
    url = sys.argv[1] if len(sys.argv) > 1 else "https://example.com"
    selectors = sys.argv[2:] if len(sys.argv) > 2 else ["body"]
    print(generate_test(url, selectors))

Usage:

python engineering-team/playwright-pro/scripts/generate-test.py \
  "https://myapp.com/login" \
  "input[name='email']" \
  "button[type='submit']"

Stacking Skills

# Claude Code
/use senior-architect
/use aws-solution-architect
/use skill-security-auditor

# Then ask:
"Review my architecture for a multi-tenant SaaS with SOC 2 compliance requirements."

Using Skills with Code Generation

User: "Generate a REST API with CRUD operations for a blog post resource."

AI (with senior-backend skill):
- Analyzes requirements
- Follows RESTful patterns from skill
- Generates code with proper validation
- Includes security best practices
- Adds tests and documentation

Troubleshooting

Skills Not Loading

Claude Code:

# Check installation
ls ~/.claude/skills/

# Reinstall
/plugin uninstall my-skill@claude-code-skills
/plugin install my-skill@claude-code-skills

Gemini CLI:

# Check installation
ls ~/.gemini/skills/

# Reinstall
./scripts/gemini-install.sh

Conversion Script Fails

# Ensure you're in the repo root
cd /path/to/claude-skills

# Check Python version (requires 3.7+)
python3 --version

# Run with verbose output
./scripts/convert.sh --tool cursor --verbose

Python Tools Not Executable

# Make scripts executable
find . -name "*.py" -type f -exec chmod +x {} \;

# Or run with python3 explicitly
python3 engineering-team/playwright-pro/scripts/generate-test.py

Persona Not Activating

# Ensure persona file is in correct location
# Claude Code
cp agents/personas/startup-cto.md ~/.claude/agents/

# For other tools, convert first
./scripts/convert.sh --tool cursor

# Verify file exists
cat ~/.claude/agents/startup-cto.md

Skill Security Concerns

Use the skill-security-auditor before installing third-party skills:

# Install the security auditor
/plugin install skill-security-auditor@claude-code-skills

# Audit a skill directory
/use skill-security-auditor
"Audit the skills in /path/to/untrusted-skills/"

Configuration

Environment Variables

Skills respect these environment variables:

# General
export CLAUDE_SKILLS_PATH="$HOME/.claude/skills"
export GEMINI_SKILLS_PATH="$HOME/.gemini/skills"

# For tools with API integration
export OPENAI_API_KEY="your-key-here"
export ANTHROPIC_API_KEY="your-key-here"

# Project-specific
export PROJECT_ROOT="/path/to/project"
export DOCS_OUTPUT_DIR="./docs"

Tool-Specific Configuration

Cursor (.cursor/config.json):

{
  "skills_path": ".cursor/rules",
  "auto_load": true
}

Aider (.aider.conf.yml):

conventions: CONVENTIONS.md
auto_commits: true

Windsurf (.windsurf/config.yml):

skills_dir: .windsurf/skills
auto_activate: true

Advanced Usage

Creating Skill Bundles

# Create a custom bundle
mkdir -p my-bundle/skills
cp -r engineering-team/senior-architect my-bundle/skills/
cp -r product-team/product-manager my-bundle/skills/
cp -r marketing-skill/content-pod/* my-bundle/skills/

# Install bundle
cp -r my-bundle/skills/* ~/.claude/skills/

Automating Skill Updates

#!/bin/bash
# scripts/update-skills.sh
cd ~/claude-skills
git pull origin main
./scripts/convert.sh --tool all
./scripts/install.sh --tool cursor --target ~/my-project --force
echo "Skills updated!"

Using Skills in CI/CD

# .github/workflows/skill-audit.yml
name: Security Audit
on: [push]
jobs:
  audit:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
