+## ⚠️ MANDATORY: Remove Unused Code
+
+**Never keep unused code around. Always delete it completely.**
+
+- When a feature is removed, delete ALL related code (implementation, tests, types, configs)
+- Do NOT comment out code "for later" - use version control history
+- Do NOT skip tests for removed functionality - delete them
+- Do NOT leave dead code paths, unused imports, or orphaned functions
+- When refactoring, actively look for and remove any code that becomes unused
+
+> **Delete unused code immediately. No exceptions.**
