📌 A viral X post by Granite highlights Anthony Fu—Vercel design engineer and creator of Vitest, VueUse, Slidev, and UnoCSS—open-sourcing his personal Claude Code agent skills at github.com/antfu/skills. The MIT-licensed collection packages his modern JavaScript stack expertise as drop-in, shareable skills for agentic engineering.
👨💻 Who Is Anthony Fu?
Design engineer at Vercel and core team member of Vue, Nuxt, and Vite. Creator of Vitest, VueUse, Slidev, UnoCSS, and other widely used open-source tools, with roughly 40K GitHub followers.
🧠 What Is antfu/skills?
A curated collection of Agent Skills—markdown knowledge modules that teach Claude Code (and compatible agents) Anthony Fu's preferences, conventions, and best practices for the modern JS stack.
📦 What's Inside
Hand-maintained skills (antfu, antfu-design), docs-generated skills for Vue, Nuxt, Vite, Vitest, UnoCSS, Pinia, and pnpm, plus vendored skills from Slidev, VueUse, Turborepo, and Vercel's web-design guidelines.
⚡ How to Install
One command via the Vercel skills CLI: pnpx skills add antfu/skills --skill='*'. Add -g for a global install. Skills are on-demand and drop into any compatible project.
🚀 Why It Matters
Turns a generic Claude Code setup into a domain-expert agent for Vue/Vite/Nuxt work. Uses git submodules tied to upstream docs so skills stay current—a pattern you can fork for your own stack.

Details
The source post comes from Granite (@Granite0x), who argues Anthony Fu has quietly built much of the modern web tooling ecosystem in his spare time—and now shared his private Claude Code configuration instead of keeping it closed. The tweet points to antfu/skills, describing it as a drop-in loadout that moves developers from casual "vibe coding" toward structured agentic engineering.
The repository is Anthony Fu's curated Agent Skills collection, built on the agentskills.io standard. It bundles his opinionated workflow preferences (ESLint, pnpm, Vitest, Vue conventions) with documentation-derived skills synced from official Vue, Nuxt, Vite, and Vitest sources via git submodules. Vendored skills from projects like VueUse, Slidev, and Turborepo round out a one-stop kit for the Vite/Nuxt ecosystem.
Fu describes the project as a proof-of-concept for generating and keeping agent skills in sync with upstream documentation. Skills are shareable and loaded on demand, scaling beyond what a single context window can hold—complementary to always-on AGENTS.md files. The repo includes tooling to fork and generate your own customized skill collection.
Granite's post also links to a companion X Article, "Build Your Opus 4.8 Workspace on GitHub," covering the broader Claude Code setup surface: skills, hooks, subagents, MCP servers, workflow YAMLs, and canary deployments.
