| [`tfsec_scan`](#tfsec_scan) | Scan Terraform for security issues |
| [`tf_to_ncl`](#tf_to_ncl) | Convert HCL to Nickel format |
| [`tf_validate`](#tf_validate) | Validate Terraform configurations |
| [`tf_plan`](#tf_plan) | Generate Terraform plan |

### tfsec_scan

Scan Terraform for security issues.

### tf_to_ncl

Convert HCL to Nickel format.

### tf_validate

Validate Terraform configurations.

### tf_plan

Generate Terraform plan.

## Usage Examples

```python
# Scan infrastructure for security issues
@omni("tf-ncl.tfsec_scan", {"path": "infrastructure"})

# Convert Terraform to Nickel
@omni("tf-ncl.tf_to_ncl", {"tf_file": "main.tf", "output": "main.ncl"})
