# Copilot Instructions ## Style - ES modules, destructured imports, double quotes, 2 spaces, semicolons - Arrow functions, async/await, object/array destructuring ## Commands - `bun dev` - development server - `bun run test` - run tests (using vitest) - `bun run test:watch` - run tests in watch mode - `bun run test:coverage` - run tests with coverage - `bun run check` - lint and format - `bun run test:imap` - IMAP integration test ## Workflow - Try to use a TDD approach first - Run tests and formatting after code changes - Use single tests for performance
