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.

≈71 tokens for metadata: the name and description. ≈831 when used: this file. ≈16k more on demand in 14 files.

Description uses 3.5% of example budget

Before choosing a Skill, your Agent reads its name and description. All available Skills share that space.

  • A shorter description leaves more room for other Skills. This entry exceeds our 1% size suggestion.

In our Claude Code example, all Skill names and descriptions share 8,000 characters. This Skill uses ≈284 characters, or 3.5%.

The 1% threshold is a size suggestion. Longer descriptions can still fit.

Your model, settings, and other Skills decide how much text your Agent can read.

Example settings and source

The example uses a 200k-token context and default Claude Code settings. The count includes the name, description, separators, and when_to_use when present. Codex also counts local file paths.

Skit's source and limits: Codex 0.160.1, Claude Code 2.1.292.

The skill is based on Nitro v3 (beta, 3.0.260903), generated at 2026-09-25.

Nitro is a framework-agnostic, deployment-agnostic server toolkit powered by H3 v2, unstorage, and Vite/Rolldown/Rollup. It powers Nuxt and works standalone. From one codebase it builds optimized output for Node.js, Bun, Deno, Cloudflare, Vercel, Netlify, and more.

Key capabilities:

  • Filesystem routing with H3 v2 event handlers, dynamic params, and method suffixes.
  • Route rules for declarative caching, headers, redirects, proxying, and CORS.
  • Caching layer (cached handlers/functions, SWR) on top of the unstorage KV layer.
  • Runtime config overridable via NITRO_* env vars.
  • Tasks (on-demand + scheduled/cron), WebSockets/SSE, a SQL database layer, and OpenAPI auto-docs.
  • Plugins & lifecycle hooks, custom renderer/server entry, and portable deployment presets.

Key v3 changes (vs. nitropack v2): the package is renamed nitropack → nitro with H3 v2 (web-standard Request/Response); auto-imports are removed (import everything explicitly); directory scanning is opt-in via serverDir; useStorage → useKV (nitro/kv) and the storage config option → kv; cache swr now defaults to false. If unsure about v2-vs-v3 APIs, read advanced-migration first.
