What it does

Vue Inspect is an agent skill from scott-fryxell/brayness. Inspect live Vue 3 component state via agent-browser eval - no Devtools extension, no console.log. Triggers - "inspect this Vue component", "what's the current value of this ref", "read setupState", "walk the Vue tree", "Vue devtools alternative". Vue 3 Composition API only.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `SOURCES.md`, `references/api-surface.md` and `references/common-use-cases.md`).

It sits in Productivity & Automation, covering Browser automation. It works with Vue.js and React. The repository describes itself as: A harness for the anxious digital mind. A safe place for creatives to keep their creative soul while exploring digital skills. The licence is MIT.

When your agent uses it

  • - inspect this Vue component
  • Whats the current value of this ref
  • Read setupState
  • Walk the Vue tree

Example prompts

  • “inspect this Vue component”
  • “s the current value of this ref”
  • “read setupState”
  • “/vue-inspect”

What it can do on your machine

Read from SKILL.md and the folder at commit 71f10e2. 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 bash).

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

  • Network

    No URLs in SKILL.md.

    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

Vue Inspect loads about 779 tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 313 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
~779
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.1k

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

Inspect live Vue 3 component state via agent-browser eval - no Devtools extension, no console.log. Triggers - "inspect this Vue component", "what's the current value of this ref", "read setupState", "walk the Vue tree", "Vue devtools alternative". Vue 3 Composition API only.

vue-inspect

Vue 3 exposes its whole runtime state on plain DOM nodes and component instances - no extension required. This skill is a set of copy-pasteable eval snippets (run via agent-browser eval "(() => { ... })()") that walk that internal state to answer "what does this component actually think its data is right now."

It exists because agent-browser has native React Devtools integration (--enable react-devtools + react tree/react inspect/react renders) but nothing built in for Vue. These snippets close that gap using Vue 3's own internals directly.

When to use

  • Runtime-dependent state: what a ref/prop/computed actually is right now (mid-animation, post-interaction), what's actually mounted, whether a component exists in the rendered tree at all.
  • Not for static reads - prop definitions and template markup live in the source file; go read it instead.

Quick start

Confirm the page is a Vue 3 app and get the version:

bash
agent-browser eval "document.querySelector('#app').__vue_app__.version"

If #app isn't the mount point, find it: Vue attaches __vue_app__ to whatever element was passed to app.mount(...). document.querySelector('[data-v-app]') or inspecting the root of the visible DOM tree usually finds it if the id differs.

Full reference snippets (tree walker, name-finder, state reader) live in references/api-surface.md - copy them directly into an eval call.

The one gotcha that will cost you time

setupState auto-unwraps top-level refs. setup.some_ref is the raw value (0, false, {...}), not a ref object - setup.some_ref?.value silently returns undefined. Check typeof setup.some_ref before assuming you need .value. Full explanation in references/troubleshooting-workarounds.md.

Files

  • references/api-surface.md - the internal properties (__vue_app__, subTree, setupState, type.name) and the three core snippets (tree walker, name-finder, state reader).
  • references/common-use-cases.md - worked examples: reading a ref, finding a v-for instance, checking props, confirming mount/unmount, reading provide/inject, catching a mid-animation state.
  • references/troubleshooting-workarounds.md - known failure modes (ref unwrapping, functional components, Teleport/Suspense/KeepAlive, multiple apps, Vue 2 differences, prod build name-mangling) with fixes.

Pairs with

  • agent-browser - runs the eval snippets; also has native React Devtools support for the equivalent React workflow (react tree, react inspect <id>).
