- "Create a compliance dashboard"

## Best Practices

- Run compliance checks weekly
- Automate with Lambda/EventBridge
- Track compliance trends over time
- Document exceptions with justification
- Integrate with AWS Security Hub
- Use AWS Config Rules for continuous monitoring

## Kiro CLI Integration

```bash
kiro-cli chat "Use aws-compliance-checker to run CIS benchmark"
kiro-cli chat "Generate PCI-DSS report with aws-compliance-checker"
```

## Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
