 ## Review and code-quality expectations
 
-Every slice should get a sanity review, not merely a successful transplant.
+Run the installed `pre-submit-review` skill before creating or updating any
+pull request; the owner asked for a forced mechanism after #11, and it is the
+only copy of the procedure. Every slice should get a sanity review, not merely
+a successful transplant.
 Fix obvious smells, poor naming, needless allocation, awkward state shapes, and
 accidental complexity while keeping the slice focused. It is not necessary to
 fully understand or redesign every complicated subsystem.
