+# **What it does**: Closes issues that don't have enough information to be
+#                   actionable.
+# **Why we have it**: To remove the need for maintainers to remember to check
+#                     back on issues periodically to see if contributors have
+#                     responded.
+# **Who does it impact**: Everyone that works on docs or docs-internal.
