           body: |
             This PR updates the list of Discourse deprecations in the `deprecation-ids.yml` file.
-            Any files that need to be manually checked for deprecation IDs that are not found by the
-            script are in `files_to_debug.txt`. Please delete this file if present before merging.
+            
+            The `files_to_debug.txt` file contains paths of files that should be checked for deprecation IDs that
+            were not found by the script. Please remove those entries (**but not the file**) before merging.
