# Policy-as-Code Generator

Converts natural language compliance requirements into executable policy code. Generates OPA Rego, AWS Config Rules, Sentinel policies, or Terraform modules.

## Quick Commands

**Generate OPA Rego policy:**

```bash
node plugins/grc-engineer/scripts/generate-policy.js "Ensure no S3 buckets are public and all must have a 'Department' tag" rego
```

**Generate AWS Config Rule:**

```bash
node plugins/grc-engineer/scripts/generate-policy.js "All EC2 instances must have encryption enabled" aws-config
```

**Generate Sentinel policy:**

```bash
node plugins/grc-engineer/scripts/generate-policy.js "Terraform plans must not create resources without required tags" sentinel
```

## Supported Output Formats

- **rego** - Open Policy Agent (OPA) Rego language
- **sentinel** - HashiCorp Sentinel policy language
- **aws-config** - AWS Config Rule (Python/Lambda)
- **terraform** - Terraform policy module
- **checkov** - Checkov YAML policy
