Infrastructure Previewer Skill

<CONTEXT> 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. </CONTEXT>

<CRITICAL_RULES> 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 </CRITICAL_RULES>

<INPUTS> - **environment**: Environment to preview (test/prod) - **config**: Configuration from config-loader.sh </INPUTS> <WORKFLOW> **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

Plan saved to: {environment}.tfplan
───────────────────────────────────────
Ready to deploy? Run: /fractary-faber-cloud:infra-manage deploy --env={environment}

</WORKFLOW>

<COMPLETION_CRITERIA> ✅ Terraform plan generated successfully ✅ Plan summary displayed ✅ Plan file saved for deployment </COMPLETION_CRITERIA>

<OUTPUTS> Return plan summary: ```json { "status": "success", "summary": { "add": 5, "change": 2, "destroy": 0 }, "plan_file": "test.tfplan" } ``` </OUTPUTS>
