Curated by Skill Harbor — the official agent skill for shadcn/ui from the shadcn-ui team: it manages components and projects through the CLI (`init`, `add`, `search`, `view`, `docs` — always via the project's package runner: npx, pnpm dlx, or bunx) and, more importantly, encodes the critical rules the agent must enforce when writing UI — styling (semantic color tokens, `gap-*` instead of `space-x-*`/`space-y-*`, `size-*` for equal dimensions, `cn()` for conditionals, no manual `z-index` on overlays), forms (`FieldGroup` + `Field`, `InputGroup` primitives, `ToggleGroup` for 2–7 option sets, `data-invalid` + `aria-invalid` validation states), composition (items always inside their `Group`, `asChild`/`render` for custom triggers, required `DialogTitle` for accessibility, full `Card` composition, `Avatar` always with `AvatarFallback`), components-over-custom-markup (`Alert` for callouts, `Empty` for empty states, `Skeleton` for loading, `Badge` over styled spans), icons (`data-icon` in buttons, no sizing classes), and chat UI (compose `MessageScroller`, `Message`, `Bubble`, `Attachment`, `Marker` — never hand-rolled bubbles). It also ships the workflow (check installed components before `add`, fetch `docs` URLs before touching a component, `--dry-run`/`--diff` before updates, never `--overwrite` without approval), the project-context fields it reads from `info` (aliases, isRSC for `"use client"`, tailwindVersion, style, base radix/base, iconLibrary, resolvedPaths, framework, packageManager), component registries (explicit registry required — never guess), and preset management (decode/apply/resolve preset codes, overwrite vs partial vs merge vs skip on preset switches). By @shadcn-ui, listed here with credit to its creator. Honest caveats: this is an agent-invocable skill (`user-invocable: false`) — it teaches your agent, it doesn't install anything by itself; its styling rules are opinionated and will fight existing projects that use raw color values or `space-y-*` habits; the `rules/*.md` reference files it links to ship alongside the SKILL.md and should be installed together. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: a Muse account with skill installation enabled Install "shadcn/ui Agent Skill" for me. Agent skill for shadcn/ui — CLI workflows, critical styling and composition rules, registries, presets Repository: https://github.com/shadcn-ui/ui/blob/main/skills/shadcn/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "shadcn-ui". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. save my API key in the vault). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
