+# Debug Variables Task Include
+
+This task file (`tasks/utils/debug/main.yml`) outputs key variables for troubleshooting Ansible roles and playbooks.
+
+## Purpose
+
+Use this file to quickly debug and inspect variables such as `application_id`, `applications`, `ports`, and more. It helps identify missing or misconfigured variables during playbook runs.
+
+## Usage
+
+Include the debug file in any task list or role:
+
+```yaml
+- import_tasks: utils/debug/main.yml
+````
+
+or
+
+```yaml
+- include_tasks: utils/debug/main.yml
+```
+
+Optionally, enable it conditionally:
+
+```yaml
+- import_tasks: utils/debug/main.yml
+  when: enable_debug | default(false)
+```
+
+**Note:**
+The path is relative to the directory of your task file.
+
+---
+
+This tool is intended for development and troubleshooting only. Remove or disable it in production runs.
