# OpenTofu Open-Source Infrastructure Engine & Migration

Operates OpenTofu (open-source Terraform fork): migrating existing .tf codebases, managing state encryption at rest (OpenTofu native state encryption), evaluating plans, and provider compatibility.

## When to Invoke
Invoke this skill whenever you need to:
- migrate from terraform to opentofu
- enable opentofu state encryption
- run tofu plan

## Execution SOP & Rules
1. Install tofu CLI binary from official Linux Foundation package repositories.
2. Run tofu init to download provider plugins and verify state lock compatibility.
3. Configure tofu { encryption { key_provider 'aws_kms' {...} } } for end-to-end encrypted state.
4. Execute tofu plan -out=tfplan and verify all provider resources remain intact.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
