+name: Never use 'as any'
+description: User strongly prohibits using 'as any' type casts - always use proper types instead
+type: feedback
+---
+
+Never use `as any` in this codebase. Always define proper types. If a value needs a type that doesn't exist yet, add the field to the type definition (e.g., `id?: int` on UserOutput) rather than casting with `as any`.
+
+**Why:** The user considers `as any` a serious code quality violation. It bypasses the type system entirely and defeats the purpose of using TypeScript.
+
+**How to apply:** When you need to access a property that isn't on the current type, extend the type to include it. Never cast to `any` as a shortcut.
