Unhead Vue Skilld

What it does

When your agent uses it

• Debugging code that imports @unhead/vue
• Sets up Unhead SSR / streaming SSR / build plugins in a Vue app

Example prompts

• “/unhead-vue-skilld”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Async context: calling useHead() after an await inside onMounted()/watchers throws useHead() was called without provide context. Fix, in…
2. 2Never call useHead() inside a watcher callback: each call pushes a new entry and duplicates tags. Pass the reactive value into one…
3. 3Deduplication key is key, not hid/vmid: meta: [{ key: 'description', name: 'description', content: '...' }].
4. 4Inline content: innerHTML (was children in v1); body scripts use tagPosition: 'bodyClose' (was body: true).
5. 5Untrusted input: use useHeadSafe(); it whitelists attributes and strips scripts/handlers.
6. 6Head instance access in Vue: use injectHead() from @unhead/vue, not getActiveHead() from unhead; only the former binds to component…

What it can do on your machine

Read from SKILL.md and the folder at commit c8994af. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and vue).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • unhead.unjs.io

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unhead Vue Skilld loads about 1.9k tokens when it runs, and up to ~7.5k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 533 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~72

When it runs · the whole SKILL.md, loaded when a task matches

~1.9k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~7.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Full-stack <head> manager for Vue (@unhead/vue 3.x). Use when writing, reviewing, or debugging code that imports @unhead/vue, calls useHead, useSeoMeta, useHeadSafe, useScript, injectHead, createHead, or sets up Unhead SSR / streaming SSR / build plugins in a Vue app.

// entry-client.ts (SPA or hydration)
import { createHead } from '@unhead/vue/client'
import { createApp } from './main'

const { app } = createApp()
const head = createHead()
app.use(head)
app.mount('#app')

// entry-server.ts (SSR)
import { createHead } from '@unhead/vue/server'
import { renderToString } from 'vue/server-renderer'
import { createApp } from './main'

export async function render(url: string) {
  const { app } = createApp()
  const head = createHead()
  app.use(head)
  const html = await renderToString(app)
  return { html, head } // render tags later with transformHtmlTemplate(head, template)
}

<script setup lang="ts">
import { useHead, useSeoMeta } from '@unhead/vue'

useHead({
  title: () => `${user.value.name} - Profile`, // getters, refs, computed all reactive
  titleTemplate: '%s | My Site',
  meta: [{ name: 'description', content: () => description.value }],
})

useSeoMeta({ // flat, type-safe keys; og/twitter handled automatically
  ogTitle: 'My Page',
  ogImage: 'https://example.com/image.jpg',
})
</script>

// Third-party scripts
import { useScript } from '@unhead/vue'

const { proxy, onLoaded, status } = useScript(
  { src: 'https://example.com/analytics.js' },
  { use: () => window.analytics, trigger: 'client' },
)
proxy.track('pageview') // queued until the script loads

import { createHead } from '@unhead/vue/client'
import { AliasSortingPlugin, TemplateParamsPlugin } from '@unhead/vue/plugins'

const head = createHead({ plugins: [TemplateParamsPlugin, AliasSortingPlugin] })

// vite.config.ts
import { Unhead } from '@unhead/vue/bundler'

export default defineConfig({
  plugins: [vue(), Unhead()], // add { streaming: true } for streaming SSR
})
