# Terraform Skills

HashiCorp's official Terraform agent skills for infrastructure-as-code development.

## Available Sub-Skills

| Skill | File | Use When |
|-------|------|----------|
| Style Guide | [terraform-style-guide-SKILL.md](terraform-style-guide-SKILL.md) | Writing or reviewing Terraform HCL code |
| Testing | [terraform-test-SKILL.md](terraform-test-SKILL.md) | Creating .tftest.hcl test files, writing assertions, mocking |
| Module Refactoring | [refactor-module-SKILL.md](refactor-module-SKILL.md) | Transforming monolithic configs into reusable modules |

## Quick Reference

### File Organization
| File | Purpose |
|------|---------|
| `terraform.tf` | Version requirements |
| `providers.tf` | Provider configurations |
| `main.tf` | Primary resources |
| `variables.tf` | Input variables (alphabetical) |
| `outputs.tf` | Output values (alphabetical) |
| `locals.tf` | Local values |

### Key Conventions
- Two spaces per indent, no tabs
- Lowercase with underscores for names
- Every variable needs `type` and `description`
- Every output needs `description`
- Prefer `for_each` over `count`
- Never hardcode credentials

### Validation
```bash
terraform fmt -recursive
terraform validate
```
