Vueuse Core Skilld

What it does

When your agent uses it

• Writing code that imports @vueuse/core
• @vueuse/shared (VueUse)

Example prompts

• “@vueuse/core”
• “@vueuse/shared”
• “/vueuse-core-skilld”

Requirements

• Node.js

Workflow steps

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

1. 1No templateRef. Removed in v15.0.0
2. 2Timer options are gone; pass scheduler. The deprecated per-composable
3. 3useThrottleFn now fires trailing calls by default (trailing default
4. 4useEventSource handles SSE message events and triggers both
5. 5deepRefs default flips next major. It defaults to true today with an

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).

  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):

  • github.com
  • vueuse.org

  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

Vueuse Core Skilld loads about 1.5k tokens when it runs, and up to ~7.2k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 421 words of instructions outside code blocks.

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

~87

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

~1.5k

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

~7.2k

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

Collection of essential Vue Composition Utilities. ALWAYS use when writing code that imports "@vueuse/core" or "@vueuse/shared" (VueUse). Provides the v15.0.0 API surface, v14 to v15 migration rules, new composables (useWebMCP, useTemporalNow, useLiveAnnouncer, useElementOverflow), deprecations, and configuration best practices.

import { useLocalStorage, useDark, useTitle, useThrottleFn } from '@vueuse/core'

// Reactive getter args enable derived values without computed()
const isDark = useDark()
const title = useTitle(() => isDark.value ? 'Night' : 'Day')

// Storage with schema evolution: mergeDefaults fills new keys
const settings = useLocalStorage('settings', { theme: 'light', density: 'comfortable' }, { mergeDefaults: true })

// v15 throttle fires a trailing call by default; 3rd arg is `trailing`
const onResize = useThrottleFn(handler, 200, false, true) // trailing=false, leading=true

import { useWebMCP } from '@vueuse/core'

// Register a WebMCP tool for browser agents (new in v15)
const { isSupported, isRegistered, error } = useWebMCP({
  name: 'get-current-user',
  description: 'Returns the signed-in user id',
  inputSchema: { type: 'object' },
  execute: () => ({ userId: user.value?.id ?? null }),
})
