## 🐛 Troubleshooting

### Issue: Signature verification failed
```bash
# Check if public key is imported
gpg --list-keys

# Import missing key
gpg --import public_key.asc

# Re-verify
python3 clawsec.py verify skill.py
```

### Issue: Malicious detection false positive
```bash
# Add to whitelist
python3 clawsec.py whitelist skill.py

# Review threat rules
python3 clawsec.py rules --list
```

### Issue: Advisory feeds not updating
```bash
# Check network connectivity
python3 clawsec.py test-connectivity

# Clear cache
python3 clawsec.py clear-cache

# Force refresh
python3 clawsec.py refresh-advisories
```
