webpack.config.js

+					'style-loader',
+					'css-loader',


The SCSS configuration uses 'style-loader' which injects CSS into JavaScript bundles. For WordPress themes, you should use MiniCssExtractPlugin.loader to generate separate CSS files that can be properly enqueued.

theme.json

+          "name": "Primary"
+        },
+        {
+          "slug": "secondary", 


Extra trailing space after 'secondary' should be removed for consistency.

tests/js/theme.test.js

+
+			// Test theme initialization
+			expect( () => {
+				const {{theme_slug|camelCase}} = {


Using mustache variables directly in JavaScript variable names can cause syntax errors. Consider using a more predictable variable name or ensure proper validation of the camelCase transformation.

Copilot · 2025-10-19T02:45:41Z

src/js/theme.js

+} );
+
+// Theme utilities
+const {{theme_slug|camelCase}} = {


The mustache variable {{theme_slug|camelCase}} used as a JavaScript object name could result in invalid syntax if the camelCase transformation produces reserved keywords or invalid identifiers.

Copilot · 2025-10-19T02:45:41Z

src/js/editor.js

+		const { PanelBody, TextControl } = wp.components;
+		const { __ } = wp.i18n;
+
+		const {{theme_slug|camelCase}}Sidebar = () => {


Using mustache variables in function names can lead to invalid JavaScript syntax. Consider using a static function name or implementing proper validation for the camelCase transformation.
