**Step 1: Read Review Guide**
Reference: reviews/skill-mcp.md

**Step 2: Scan for Red Flags**
Check against patterns/red-flags.md:
- Obfuscation (base64, hex encoding, eval)
- Credential access (env vars, file reads)
- Network exfiltration (unexpected HTTP calls)
- Code injection (exec, eval, subprocess)
- Privilege escalation (sudo, system commands)

**Step 3: Assess Trust Level**
- Source tier: [1-5]
- Repository age: [X months]
- Star count: [X]
- Maintainer reputation: [verified/unknown]

**Step 4: Generate Report**
Use template: templates/report-skill.md
Risk level: [LOW/MEDIUM/HIGH/REJECT]

**Step 1: Read Repository Guide**
Reference: reviews/repository.md

**Step 2: Check Metadata**
- Account age
- Commit history (sudden activity spikes?)
- Contributor diversity
- Issue/PR engagement

**Step 3: Code Analysis**
Scan for:

undefined

**Example: Dependency Audit**

```javascript
// Check package.json for typosquatting
const package = require('./package.json');

const suspiciousPatterns = [
  'requset',  // typo of 'request'
  'electorn', // typo of 'electron'
  'loadsh',   // typo of 'lodash'
];

Object.keys(package.dependencies).forEach(dep => {
  if (suspiciousPatterns.includes(dep)) {
    console.log(`⚠️ Suspicious dependency: ${dep}`);
  }
});

**Step 1: Read URL/Document Guide**
Reference: reviews/url-document.md

**Step 2: Check Domain**
- Newly registered? (< 30 days)
- Typosquatting official domains?
- Known malicious IP ranges?

**Step 3: Content Analysis**
Scan for:
- Prompt injection attempts
- Social engineering tactics
- Hidden instructions in metadata
- Malicious redirects

**Step 4: Social Engineering Check**
Reference: patterns/social-engineering.md
- Authority impersonation
- Urgency manipulation
- Emotional triggers

**Step 5: Generate Report**
Use template: templates/report-url.md

undefined

undefined

**Step 1: Read On-Chain Guide**
Reference: reviews/onchain.md

**Step 2: Validate Format**
- Correct checksum?
- Valid network?
- Known contract type?

**Step 3: AML Risk Assessment**
Query available tools:
- Sanctioned address lists
- Mixer/tumbler usage
- Theft reports
- Scam databases

**Step 4: Transaction Analysis**
- Funding sources
- Interaction patterns
- Contract calls

**Step 5: Generate Report**
Use template: templates/report-onchain.md

import re
from eth_utils import is_address, to_checksum_address

def validate_ethereum_address(addr):
    """Validate Ethereum address format and checksum"""
    
    # Check basic format
    if not re.match(r'^0x[a-fA-F0-9]{40}$', addr):
        return {'valid': False, 'reason': 'Invalid format'}
    
    # Check if it's a valid address
    if not is_address(addr):
        return {'valid': False, 'reason': 'Invalid address'}
    
    # Verify checksum if mixed case
    if addr != addr.lower() and addr != addr.upper():
        try:
            checksum_addr = to_checksum_address(addr)
            if addr != checksum_addr:
                return {
                    'valid': False,
                    'reason': 'Checksum mismatch',
                    'correct': checksum_addr

        except ValueError:
            return {'valid': False, 'reason': 'Invalid checksum'}
    
    return {'valid': True, 'address': addr}

**Example: AML Risk Check (Conceptual)**

```python

response = requests.get(
    f'https://api.misttrack.io/v1/address_risk',
    params={'address': address, 'chain': chain},
    headers={'Authorization': f'Bearer {api_key}'}
)

data = response.json()
return {
    'risk_score': data.get('risk_score'),
    'categories': data.get('risk_categories', []),
    'is_sanctioned': data.get('is_sanctioned', False),
    'mixer_usage': data.get('mixer_exposure', 0)
}

**Step 1: Read Product Guide**
Reference: reviews/product-service.md

**Step 2: Architecture Analysis**
- Centralized vs decentralized
- Data custody model
- Permission model
- Update mechanism

**Step 3: Security Assessment**
- Audit history
- Bug bounty program
- Incident response track record
- Open source components

**Step 4: Generate Report**
