+        - Use `fix:` for bug fixes in application code
+        - Use `chore:` for infrastructure, CI/CD, dependencies, tooling
+        - Use `docs:` for documentation-only changes
+        - Use `refactor:` for code restructuring without functional changes
+        - Include body with technical details and reference any issue numbers
