# 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:**
```bash
# 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**
   ```bash
   # 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**
   ```bash
   # 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**
   ```bash
   # 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**
   ```bash
   # 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**
