What it does

Uithing is an agent skill from BayBreezy/ui-thing. Manages UI Thing components, prose, blocks, themes, shortcuts, docs, and MCP-driven workflows in Nuxt projects and in the UI Thing source repo. Use when working with ui-thing CLI commands like ui-thing init, ui-thing add, ui-thing prose, ui-thing block, or ui-thing theme; when editing app/components/Ui, docs, generators, or generated registries; or when converting pasted React/shadcn code into native Vue/Nuxt UI Thing components.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including reference files and assets (for example `agents/openai.yaml`, `cli.md` and `mcp.md`).

It sits in Frontend & Design, covering Design systems and Technical documentation. It works with Nuxt, shadcn/ui, React and Vue.js. The repository describes itself as: A modern set of Nuxt components built with Reka UI & TailwindCSS. Inspired by shadcn/ui & shadcn-vue.

When your agent uses it

Working with ui-thing CLI commands like ui-thing init
Editing app/components/Ui
Generated registries
Converting pasted React/shadcn code into native Vue/Nuxt UI Thing components

Example prompts

“Use the uithing skill to manage UI Thing components, prose, blocks, themes, shortcuts, docs, and MCP-driven workflows in Nuxt projects and in the UI…”
“/uithing”

Workflow steps

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

Use existing UI Thing components first.
Compose existing Ui* families before writing custom markup.
Preserve Reka accessibility, focus handling, keyboard behavior, and portal behavior.
Preserve Nuxt conventions: auto-imports, SFC patterns, and docs/content structure.
Treat generated registries as derived outputs, never as authoring targets.
For React conversion, preserve intent and semantics, not JSX syntax.

What it can do on your machine

Read from SKILL.md and the folder at commit f492923. 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

Uithing loads about 1.3k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 546 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~114
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~2.1k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 546 words (~1,345 tokens).

“UI Thing is a Nuxt-first, shadcn-inspired, copy-paste component system built on Vue 3, Nuxt 4, Reka UI, Tailwind CSS v4, tailwind-variants, and Nuxt Content.”
