Two developers build different tables with the same wood. User preference files make Claude build your table. Not a generic one.
Three files guide your decisions.
Architecture Most tutorials teach layer-based folders. They group files by what they are. Use feature-based folders instead. They group files by what they do. Adding a feature means touching one folder. Deleting a feature means deleting one folder. Avoid barrel exports. Import directly from the file.
State Management Pick the right tool.
- useState for local UI state.
- Zustand for shared client state.
- TanStack Query for server data. Never put server data in Zustand. It creates copies. It causes sync issues.
Testing Do not test everything at once.
- Unit tests for pure logic.
- Integration tests with real databases.
- E2E tests for critical paths. Integration tests must use real data. Mocks lie.
The Result Claude loads these files. It builds features your way. It uses the right state tool. It writes the right tests. You stop repeating yourself.
