**/*.{ts,tsx}: Use TypeScript for all new code in this codebase unless explicitly told otherwise
Use Fuselage components from @rocket.chat/fuselage for all UI work — only create custom components when Fuselage doesn't provide the needed functionality
Check Theme.d.ts for valid color tokens when working with Fuselage components
Use optional chaining with fallbacks for platform-specific APIs instead of mocks (e.g., process.getuid?.() ?? 1000) to ensure code works across all platforms without requiring mocks
TypeScript code must use strict mode
Use React functional components with hooks instead of class components
Redux actions must follow the FSA (Flux Standard Action) pattern
Use camelCase for file naming
Use PascalCase for component file names (React components)
Write self-documenting code through clear naming — avoid unnecessary comments
