-# terraform-plan
-
-Plan Terraform configuration files using the official Terraform CLI.
-
-## Inputs
-
-| Input | Required | Default | Description |
-|-------|----------|---------|-------------|
-| `terraform-dir` | No | `terraform` | Directory containing `.tf` files |
-| `terraform-version` | No | `~1.15` | Terraform version to use |
-| `var-file` | No | `""` | Path to `.tfvars` file, relative to `terraform-dir` |
-| `workspace` | No | `""` | Terraform workspace to select |
-| `jfrog-token` | No | `""` | JFrog Artifactory token for the Terraform provider registry (`TF_TOKEN_schmalz_jfrog_io`) |
-
-## Outputs
-
-No outputs are exported.
-
-Terraform `plan` only previews changes and does not produce finalized output values in state.
-
-## Usage
-
-```yaml
-- uses: https://schmalz-git.git.onstackit.cloud/schmalz/shared-actions/terraform-plan@terraform-plan-v1
-  id: tf-plan
-  with:
-    workspace: stage
-    var-file: stage.tfvars
-    jfrog-token: ${{ secrets.JFROG_TOKEN }}
-``
-
-
-## Notes
-
-- Runs `terraform init`, selects the workspace according to PR, and executes `terraform plan`.
-- Does **not** apply any changes — it only previews what Terraform would do.
-- Helps identify infrastructure changes before execution, such as:
-  - Resources that will be created
-  - Resources that will be updated
-  - Resources that will be *deleted*
-  - Resources that will be replaced
-- Useful for reviewing changes in environments.
-- Helps detect unexpected changes caused by provider version updates, module updates, variable changes, or Terraform configuration changes.
-- Improves deployment safety by showing the impact of changes before `terraform apply`.
-- Sets `TF_TOKEN_schmalz_jfrog_io` on both `init` and `plan` steps if `jfrog-token` is provided.
-- If `var-file` is provided, it is passed as `-var-file` to the plan command.
-- Commonly used in CI for pre-apply visibility, especially in pull requests or staging validation workflows.
