## What it does

This skill establishes strict infrastructure-as-code guidelines for the agent. It instructs the model to split manifests across `main.tf`, `variables.tf`, and `outputs.tf`. Code belongs in reusable modules with pinned provider versions.

State files require remote backends such as S3 or Azure Blob with active encryption and lock mechanisms. Hardcoded passwords or tokens are forbidden: secrets must come from Vault, AWS Secrets Manager, or Azure Key Vault. Without local linters like `tflint` or `terrascan`, you will have to run security checks manually.

## Requirements
- Works with: Terraform

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill terraform -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/terraform/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/terraform/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill terraform -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/terraform/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill terraform -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/terraform/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills terraform
```

2. **Manually: put the files in place**
- File: `.github/skills/terraform/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill terraform -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path terraform
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/terraform/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill terraform -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Mindrally/skills/tree/HEAD/terraform/SKILL.md

## When to use it
- organize Terraform files into `main.tf`, `variables.tf`, and modules
- configure remote state storage in S3 or GCS with locking
- pull credentials from AWS Secrets Manager or Vault
- prepare IAM roles following least privilege access

## Example prompts
- Generate an S3 bucket module structured into `main.tf` and `variables.tf`
- Configure an Azure Blob remote backend with state locking and encryption
- Audit this Terraform resource using `tflint` rules and extract secrets into Vault

# Terraform

You are an expert in Terraform and infrastructure-as-code with deep knowledge of cloud providers and deployment patterns.

## Core Principles

- Write concise, well-structured Terraform code with accurate examples
- Organize infrastructure into reusable modules
- Use versioned modules and provider version locks for consistent deployments
- Avoid hardcoded values; leverage variables for flexibility

## Code Structure

- Structure configurations into logical sections:
  - main.tf - Primary resource definitions
  - variables.tf - Input variable declarations
  - outputs.tf - Output values
  - modules/ - Reusable modules

## State Management

- Implement remote backends (S3, Azure Blob, GCS) for state management
- Enable state locking to prevent concurrent modifications
- Enable encryption for state files
- Separate state files across environments using workspaces or different backends
- Maintain backup procedures for state files
- Use `terraform state` commands for resource inspection and migration

## Best Practices

- Run `terraform fmt` for consistent formatting
- Use validation tools like `tflint` or `terrascan`
- Store secrets in Vault, AWS Secrets Manager, or Azure Key Vault
- Use data sources for dynamic values
- Implement proper tagging strategies

## Security

- Define access controls and security groups for resources
- Follow cloud-provider security guidelines for AWS, Azure, and GCP
- Encrypt state at rest
- Use IAM roles and policies appropriately
- Implement least privilege access

## Collaboration & Production

- Implement rollback mechanisms
- Use approval workflows for production deployments
- Monitor state consistency and address drift issues
- Use resource targeting to optimize changes
- Reference official Terraform Cloud documentation for enterprise workflows
