tests/type-leaks/README.md:34

• The README instructs to use cd tests/types, but the directory is named tests/type-leaks. Please update the path to cd tests/type-leaks.

cd tests/types

tests/type-leaks/README.md:13

• The test implementation scans files under the types/ directory, not src/. Please update the documentation to reflect the actual scanned paths.

1. **TypeScript source files**: Scans all `.ts` files in each package's `src/` directory

tests/type-leaks/vitest.config.ts:5

• [nitpick] The name field is set to types, which may be too generic. Consider renaming it to type-leaks to better reflect the test suite's purpose.

        name: "types",

[nitpick] The import extraction logic duplicates handling for value and type imports separately. Consider merging these conditions into a single block to reduce code duplication.

Suggested change

	// Import declarations
	if (node.type === "ImportDeclaration" && node.source?.value) {
	// Import declarations (value and type imports)
	if (node.type === "ImportDeclaration" && node.source?.value && (node.importKind === "type" || node.importKind === undefined)) {
