+# Package Import Tests
+
+This directory contains verification tests to ensure `@strands-agents/sdk` can be imported correctly in both ESM and CommonJS module formats.
+
+## Running the Tests
+
+From the root of the project:
+
+```bash
+npm run test:package
+```
+
+This command builds and installs the SDK locally, then runs both ESM and CJS import tests.
+
+## Test Structure
+
+```

+├── esm-module/     # ES Module import test
