             ## Reviewer Instructions
             ### Unit Tests 
-            - Make sure that the code being tested is not mocked out.
-            - Make sure that the code being tested is not using any external services.
+            - Ensure that external API calls or side effects are mocked out, not the function under test
+            - Each test should import the actual function being tested
+            - Mock only external dependencies, never the function itself
             - Make sure tests cover real functionality, not only type definitions
             - `expect()` syntax should be used instead of `assert()`
             - If a test is using mocks, ensure its cleaned up after the test
