Plugin Auditor

Purpose

Automatically audits Claude Code plugins for security vulnerabilities, best practice violations, CLAUDE.md compliance, and quality standards - optimized for claude-code-plugins repository requirements.

Trigger Keywords

• "audit plugin"
• "security review" or "security audit"
• "best practices check"
• "plugin quality"
• "compliance check"
• "plugin security"

Audit Categories

1. Security Audit

Critical Checks:

• ❌ No hardcoded secrets (passwords, API keys, tokens)
• ❌ No AWS keys (AKIA...)
• ❌ No private keys (BEGIN PRIVATE KEY)
• ❌ No dangerous commands (rm -rf /, eval(), exec())
• ❌ No command injection vectors
• ❌ No suspicious URLs (IP addresses, non-HTTPS)
• ❌ No obfuscated code (base64 decode, hex encoding)

Security Patterns:

# Check for hardcoded secrets
grep -r "password\s*=\s*['\"]" --exclude-dir=node_modules
grep -r "api_key\s*=\s*['\"]" --exclude-dir=node_modules
grep -r "secret\s*=\s*['\"]" --exclude-dir=node_modules

# Check for AWS keys
grep -r "AKIA[0-9A-Z]{16}" --exclude=README.md

# Check for private keys
grep -r "BEGIN.*PRIVATE KEY" --exclude=README.md

# Check for dangerous patterns
grep -r "rm -rf /" | grep -v "/var/" | grep -v "/tmp/"
grep -r "eval\s*\(" --exclude=README.md

Audit Process

When activated, I will:

1. Security Scan

   bashCopy

   # Run security checks
   grep -r "password\|secret\|api_key" plugins/plugin-name/
   grep -r "AKIA[0-9A-Z]{16}" plugins/plugin-name/
   grep -r "BEGIN.*PRIVATE KEY" plugins/plugin-name/
   grep -r "rm -rf /" plugins/plugin-name/
   grep -r "eval\(" plugins/plugin-name/
   

2. Structure Validation

   bashCopy

   # Check required files
   test -f .claude-plugin/plugin.json
   test -f README.md
   test -f LICENSE
   
   # Check component directories
   ls -d commands/ agents/ skills/ hooks/ mcp/ 2>/dev/null
   

3. Best Practices Check

   bashCopy

   # Check for TODO/FIXME
   grep -r "TODO\|FIXME" --exclude=README.md
   
   # Check for console.log
   grep -r "console\.log" --exclude=README.md
   
   # Check script permissions
   find . -name "*.sh" ! -perm -u+x
   

4. Compliance Verification

   bashCopy

   # Check marketplace entry
   jq '.plugins[] | select(.name == "plugin-name")' .claude-plugin/marketplace.extended.json
   
   # Verify version consistency
   plugin_version=$(jq -r '.version' .claude-plugin/plugin.json)
   market_version=$(jq -r '.plugins[] | select(.name == "plugin-name") | .version' .claude-plugin/marketplace.extended.json)
   

5. Generate Audit Report
