Stencil connects AI coding agents like Claude Code, Cursor, and Codex to the Stencil pattern library—a curated collection of structured UI pattern specifications derived from actual applications. By automatically calling Stencil tools before building any UI screen, agents retrieve relevant reference patterns and use them to produce visually considered output, moving beyond generically trained defaults. This approach ensures generated UI feels intentionally designed, adapting real-world design rationale and visual language to a project's existing design system.
