Design & UI
Ruby on Rails design system guidelines for building consistent, maintainable UI with minimal abstraction. This skill should be used when creating or refactoring Rails views, partials, components, form builders, helpers, Stimulus controllers, Turbo Frames, Turbo Streams, or design tokens.

Designing meeting schedulers and booking experiences that qualify leads, set up calls well, and convert at higher rates than a generic Calendly link. Availability logic, qualification gating, prep automation, follow-up sequencing. Honest about any-time-friction (no qualification, just a booking link), interrogation-gate (so much qualification it scares users off), and qualified-fast-path (just enough qualification to set up the call well) patterns. Triggers on scheduler design, meeting booking, demo scheduling, sales call scheduling, calendar tool, booking page, qualification flow. Also triggers when sales team complains about cold demos, when booking conversion is poor, or when scheduler is being scoped for the first time.

Keep React screens thin and reusable UI in its own package, separate from app screens. Trigger when authoring or restyling a page, route, screen, or component in an app with a shared UI package—especially when a file is trending toward walls of plain <div className="..."> Tailwind markup. Favor reusing existing primitives in that package and moving new reusable units into it, while avoiding premature over-extraction. Do not trigger for non-React code, single-package apps without a shared UI package, or edits to the internals of one existing component. The package name is per-repo (see ADR-0013); do not require @repo/ui or @native/ui.

Bias UI work toward installing existing components from configured shadcn registries (the free @shadcn registry and the paid @shadcnblocks block registry) before hand-rolling them. Triggers when building or restyling React UI in a project that has a components.json with registries configured — heroes, navbars, footers, pricing tables, feature grids, dashboards, forms, auth screens, marketing sections, data tables, and other common blocks. Use the shadcn MCP tools to search, preview, and add, and always assemble at least three buildable variations with a side-by-side comparison surface before settling on one. Do NOT trigger for genuinely bespoke or domain-specific components that no registry would carry, for non-React stacks, or for projects with no registry configured
