+# Code Quality Rules
+
+1. Test Coverage:
+
+    - Before attempting completion, always make sure that any code changes have test coverage
+    - Ensure all tests pass before submitting changes
+
+2. Lint Rules:
+
+    - Never disable any lint rules without explicit user approval
+
+3. Styling Guidelines:
+    - Use Tailwind CSS classes instead of inline style objects for new markup
+    - VSCode CSS variables must be added to webview-ui/src/index.css before using them in Tailwind classes
+    - Example: `<div className="text-md text-vscode-descriptionForeground mb-2" />` instead of style objects
+
