+- [noUndeclaredVariables](https://biomejs.dev/linter/rules/no-undeclared-variables/) is now able to bind read of value to a type-only import in ambient contexts ([#4526](https://github.com/biomejs/biome/issues/4526)).
+
+  In the following code, `A` is now correctly bound to the type-only import.
+  Previously, `A` was reported as an undeclared variable.
+
+  ```ts
+  import type { A } from "mod";
+
+  declare class B extends A {}
+  ```
