+# Verifikasi Dulu
+
+Use this checklist before editing a library/controller reference:
+
+1. Find the exact call site.
+2. Confirm the library file exists.
+3. Confirm the class name inside the file.
+4. Check other repo usages of the same library.
+5. Edit only after the pattern is confirmed.
+
+This skill exists to avoid guessing when a class load error or naming mismatch appears.
