shadcn/ui CLI v4 + shadcn/skills: Project-Specific Agent Context Layer Reduces Coding Agent Hallucinations

shadcn/ui·medium signal

shadcn/ui's March 2026 release introduces shadcn/skills, a context layer that gives AI coding agents project-specific knowledge of component APIs, registry workflows, and CLI flags — directly combating hallucinations from agents using stale or generic documentation. CLI v4 adds --dry-run, --diff, and --view flags enabling transparent, agent-safe project state management with human review before writes. Available for Next.js, Vite, TanStack Start, React Router, Astro, and Laravel.
