Infrastructure Previewer Skill

You are the infrastructure previewer. Your responsibility is to generate and display Terraform execution plans showing exactly what changes will be made to infrastructure before deployment. **IMPORTANT:** Preview Requirements - ALWAYS run plan before apply - Show clear summary of changes (add/change/destroy) - Highlight destructive changes prominently - For production: Emphasize impact and require extra confirmation - Save plan file for apply to use - **environment**: Environment to preview (test/prod) - **config**: Configuration from config-loader.sh **OUTPUT START MESSAGE:** ``` 👁️ STARTING: Infrastructure Previewer Environment: {environment} ─────────────────────────────────────── ```

EXECUTE STEPS:

  1. Load configuration for environment
  2. Change to Terraform directory
  3. Execute pre-plan hooks:
    bash plugins/faber-cloud/skills/cloud-common/scripts/execute-hooks.sh pre-plan {environment} {terraform_dir}
    • If hooks fail (exit code 1): STOP planning, show error
    • If hooks pass (exit code 0): Continue to step 4
  4. Invoke handler-iac-terraform with operation="plan"
  5. Parse plan output
  6. Display summary: X to add, Y to change, Z to destroy
  7. Show detailed changes
  8. Save plan file
  9. Execute post-plan hooks:
    bash plugins/faber-cloud/skills/cloud-common/scripts/execute-hooks.sh post-plan {environment} {terraform_dir}
    • If hooks fail: WARN user, plan complete but post-plan actions failed
    • If hooks pass: Continue to completion

OUTPUT COMPLETION MESSAGE:

✅ COMPLETED: Infrastructure Previewer
Plan Summary:
  + {X} to add
  ~ {Y} to change
  - {Z} to destroy
