Tested verbatim install (clean git-clone + cp, valid strict-YAML frontmatter, all 14 reference docs present), trigger fit against the concrete description, and an OUTPUT task authoring a Nitro v3 GET route handler for /api/greet/:name plus a nitro.config.ts with SWR-cache and basic-auth route rules. A/B showed both skill and skill-less arms produced correct, idiomatic Nitro v3 code (right file-suffix routing, defineHandler/defineConfig from 'nitro', valid routeRules); the base arm had strong general Nitro knowledge, so the skill's output was same-quality, not clearly better.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 4/5
- Output vs. baseline 5/10
- Docs & honesty 5/5
What Nitro does
Nitro is the framework-agnostic server toolkit (powering Nuxt) for building and deploying web servers anywhere. Use when working with nitro.config, server routes/event handlers, route rules, caching, storage, tasks, websockets, or deploying to Node/Bun/Deno/Cloudflare/Vercel.
How to install Nitro
git clone https://github.com/antfu/skills
cd skills
mkdir -p ~/.claude/skills
cp -r skills/nitro ~/.claude/skills/nitro
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.
Commands — how to trigger Nitro
-
/nitroBuilds and deploys server routes, caching, and tasks with the Nitro toolkit.
It also activates on plain-language prompts like these:
-
Add a server route with caching using Nitro -
Deploy this Nitro server to Cloudflare -
Set up a scheduled task in nitro.config
Frequently asked questions
- Is the Nitro skill free?
- Yes. The skill itself is free from antfu/skills. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Nitro work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 12, 2026. Verdict: Works with setup. Tested verbatim install (clean git-clone + cp, valid strict-YAML frontmatter, all 14 reference docs present), trigger fit against the concrete description, and an OUTPUT task authoring a Nitro v3 GET route handler for /api/greet/:name plus a nitro.config.ts with SWR-cache and basic-auth route rules.

- What is the Nitro SkillProof Score?
- 7.6/10 — installs cleanly 5/5, triggers reliably 4/5, output vs. baseline 5/10, docs & honesty 5/5.
- How do I install Nitro?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Nitro with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
