How to Build Consistent Designs with Claude Code

Using AI coding agents like Claude Code can lead to inconsistent application designs, as they tend to create new UI elements if no centralized standard exists. To solve this, all UI components such as buttons, fonts, and colors should be refactored into a single, unified folder. The coding agent must then be explicitly instructed to only use pre-approved elements from this shared location. This process can be done step-by-step, starting with one element type at a time and using another agent to review the refactoring work. To maintain consistency long-term, the code review agent's prompts should be updated to automatically flag any new UI implementations that deviate from the established design system.
