 ### 2.1 Identify Python Files
 
-Find all Python files in the src directory:
+The Z3 repository contains Python source files primarily in `src/api/python/z3/`. Verify these files are available:
 
 ```bash
-find ${{ github.workspace }}/src -name "*.py" -type f | head -20
+# Check that src directory was checked out
+ls -la ${{ github.workspace }}/src/api/python/z3/

+# List Python files
