+# Utils Package Preference
+
+When working with the Android/KMP codebase, prefer APIs from `com.pr0gramm3r101.utils` whenever possible.
+
+## Clipboard
+- Use `supportClipboardManagerImpl` (Composable) instead of `LocalClipboardManager` / `LocalClipboard`
+- `SupportClipboardManager.setText(string: String)` is suspend; call from `scope.launch { }`
+
+## String
+- Use `String.toAnnotatedString()` for `AnnotatedString` conversion
+
+## Modifier
+- Use `Modifier.conditional` from `com.pr0gramm3r101.utils.Compose` for conditional modifiers
+
+## CompositionLocal
+- Use `CompositionLocal.invoke()` for `current` when available
+
+## Other
+- Check `Utils.kt`, `Compose.kt`, `Components.kt`, `Adaptive.kt` before implementing custom solutions
