Use this when you're editing React UI code in an existing Salesforce UI bundle, specifically anything under uiBundles/*/src/ that touches pages, components, or styling. It enforces project conventions like using appLayout.tsx for navigation, shadcn/ui with Tailwind, and runtime basename detection for routing. The skill pushes hard on design thinking, demanding you commit to a bold aesthetic direction with distinctive fonts and cohesive color palettes instead of defaulting to safe choices. It also blocks common mistakes like importing Salesforce platform modules or hardcoding base paths. Won't help if you're scaffolding a new app from scratch, that's a different skill.
