What are Claude Code Skills?

Claude Code skills are .md instruction files that teach Claude Code exactly how to perform specific tasks — with real commands, working code, and technology-specific pitfalls.

Without a skill, Claude gives you generic advice. With a skill, it gives you production-ready code.

# Install any skill in 2 seconds
mkdir -p ~/.claude/skills
curl -o ~/.claude/skills/docker-compose.md https://clskills.in/skills/docker/docker-compose.md
# Done. Claude Code now knows Docker Compose best practices.

What makes these skills different?

Most "AI prompts" are vague one-liners. Every skill here has:

• Expert role — not "you are a helpful assistant", but "you are a senior DevOps engineer"
• Prerequisite checks — what to verify before starting
• Step-by-step instructions — real commands, real API calls, not pseudocode
• Working code — 25-40 lines, copy-paste ready
• Specific pitfalls — things that actually go wrong with that exact technology

Example: Two Factor Auth skill

You are a security engineer implementing two-factor authentication.

## What to check first
- Verify speakeasy or otplib is installed: npm list speakeasy
- Confirm database has twoFactorSecret, twoFactorEnabled, backupCodes columns
- Check JWT secret or session store is configured

## Steps
1. Install packages: npm install speakeasy qrcode
2. Create 2FA setup endpoint using speakeasy.generateSecret() + qrcode.toDataURL()
3. Create verification endpoint with speakeasy.totp.verify()
4. Generate 8-10 backup codes, store hashed in database
5. Add 2FA check middleware on protected routes
6. Create backup code redemption endpoint
7. Add "remember this device" with 30-day cookie
8. Add disable 2FA endpoint requiring password + valid TOTP

## Code
[35 lines of working Express.js implementation]

## Pitfalls
- Never log TOTP secrets — they're equivalent to passwords
- Always hash backup codes with bcrypt before storing
- Use 30-second window for TOTP verification, not 60
