# 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
- The vitest framework is used for testing; the `vi`, `describe`, `test`, `it`, etc functions are defined by default in `tsconfig.json` and therefore don't need to be imported from `vitest`
- Tests must be run from the same directory as the `package.json` file that specifies `vitest` in `devDependencies`
- Run tests with: `npx vitest run <relative-path-from-workspace-root>`
- Do NOT run tests from project root - this causes "vitest: command not found" error
- Tests must be run from inside the correct workspace:
- Backend tests: `cd src && npx vitest run path/to/test-file` (don't include `src/` in path)
- UI tests: `cd webview-ui && npx vitest run src/path/to/test-file`
- Example: For `src/tests/user.test.ts`, run `cd src && npx vitest run tests/user.test.ts` NOT `npx vitest run src/tests/user.test.ts`
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
