📋 Step-by-Step Safety Guide: Using Claude Code Skills Securely
Phase 1: Pre-Installation Security
Step 1: Verify Marketplace Authenticity
# Check repository details before adding
curl -s https://api.github.com/repos/daymade/claude-code-skills | grep -E '"full_name"|"stargazers_count"'
# Expected: "full_name": "daymade/claude-code-skills", stargazers > 100
Step 2: Review Skill Source Code
# Clone and audit before installation
git clone https://github.com/daymade/claude-code-skills
cd claude-code-skills/skill-name/
# Review SKILL.md and scripts/ for suspicious operations
Step 3: Check for Credential Exposure
# Run repomix-safe-mixer standalone scanner
cd claude-code-skills/
npm install -g repomix
repomix-safe-mixer/scripts/scan.py --path ./ --report
Safety Checklist:
- Repository is official daymade/claude-code-skills
- No hardcoded API keys in skill definitions
- All scripts use environment variables for secrets
- SKILL.md documents security considerations
Phase 2: Secure Installation
Automated Installation (Recommended)
# macOS/Linux - verify script before execution
curl -fsSL https://raw.githubusercontent.com/daymade/claude-code-skills/main/scripts/install.sh -o install.sh
# Review script contents
cat install.sh
# Then execute
bash install.sh
Manual Installation (Most Secure)
# Add marketplace
claude plugin marketplace add https://github.com/daymade/claude-code-skills
# Install skills individually
claude plugin install skill-creator@daymade-skills
claude plugin install repomix-safe-mixer@daymade-skills # Install security tools first
Critical Safety Rule: Always install repomix-safe-mixer first to audit other skills.
Phase 3: Runtime Security
Step 4: Enable Claude Code Safety Features
# In ~/.claude/claude_desktop_config.json
{
"mcpServers": {
"safety-guard": {
"command": "python↗ Bright Coding Blog",
"args": ["-m", "claude_safety_guard"],
"env": {
"BLOCK_SENSITIVE_OPS": "true",
"REQUIRE_CONFIRMATION": "true"
}
}
}
}
Step 5: Audit Skill Permissions
# Each skill's manifest shows required permissions
cat ~/.claude/plugins/daymade-skills/skill-creator/skill.json | grep -A 5 "permissions"
Step 6: Test in Isolated Environment
# Create sandbox directory
mkdir -p ~/claude-sandbox
cd ~/claude-sandbox
# Test skill with limited scope
claude "Using skill-creator, create a test-skill here but only use echo commands"
Phase 4: Credential Management
Step 7: Use Environment Variables
# NEVER hardcode secrets in skills
# Create .env file in project root
cat > .env << EOF
GITHUB_TOKEN=ghp_xxxxxxxxxxxxxxxx
OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxx
EOF
# Add to .gitignore
echo ".env" >> .gitignore
Step 8: Run Pre-Execution Security Scan
# Before packaging any skill
cd your-skill-directory
repomix-safe-mixer/scripts/scan.py --pack --block-on-findings
Phase 5: Ongoing Monitoring
Step 9: Review Claude Code Session Logs
# Check for suspicious tool usage
grep -i "exec\|delete\|rm -rf" ~/.claude/projects/*/sessions/*.jsonl
Step 10: Update Skills Regularly
# Update all skills weekly
for skill in $(claude plugin list); do
claude plugin install "$skill"@daymade-skills
done
🔒 Advanced Security: The "Zero Trust" Protocol
For enterprise environments handling sensitive codebases:
1. Air-Gapped Installation
# Clone to internal Git server
git clone --mirror https://github.com/daymade/claude-code-skills \
https://github.yourcompany.com/claude-skills
# Install from internal source
claude plugin marketplace add https://github.yourcompany.com/claude-skills
2. Mandatory Code Signing
# Sign all skill scripts
gpg --armor --detach-sign skill.sh
# Verify before execution
gpg --verify skill.sh.asc skill.sh
3. Audit Trail Configuration
# Enable comprehensive logging
export CLAUDE_LOG_LEVEL=debug
export CLAUDE_LOG_FILE=/var/log/claude-audit.log
