What it does

Reui is an agent skill from Asymmetric-al/core. Build and maintain Core UI with the ReUI registry and authenticated ReUI MCP. Use for new pages/sections/features, ReUI components/examples/Pro blocks, @reui installs, REUILICENSEKEY setup, and ReUI API or documentation research. Preserve exact base-maia/Base UI, packages/ui ownership, existing shared tables, and Core tokens; use live APIs and worked examples.

Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including reference files (for example `references/docs.md`, `references/upstream-manifest.json` and `references/upstream.md`).

It sits in Frontend & Design. It works with Model Context Protocol and shadcn/ui. The repository describes itself as: A high-performance, enterprise-grade Next.js 16 application for mission-focused non-profit organizations. Built for high impact teams. The licence is AGPL-3.0.

When your agent uses it

  • New pages/sections/features
  • ReUI components/examples/Pro blocks
  • REUILICENSEKEY setup
  • Documentation research

Example prompts

  • “/reui”

Requirements

  • Node.js
  • A credential in REUI_LICENSE_KEY
  • Pre-approved tools (allowed-tools): Bash(npx shadcn@latest *), Bash(pnpm dlx shadcn@latest *), Bash(bunx --bun shadcn@latest *)

What it can do on your machine

Read from SKILL.md and the folder at commit c30c8ff. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(npx shadcn@latest *)
    • Bash(pnpm dlx shadcn@latest *)
    • Bash(bunx --bun shadcn@latest *)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • bun
    • npx
    • bunx

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

  • Network

    No URLs in SKILL.md. Its commands use npx and bunx, which can reach the network depending on how they are called.

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • REUI_LICENSE_KEY

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

Context cost

Reui loads about 3.9k tokens when it runs, and up to ~7.5k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 1,744 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~3.9k
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

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:80
    a key present only in root `.env.local` is not automatically loaded by the CLI
  • NoteMentions a .env fileSKILL.md:81
    If needed, use git-ignored `packages/ui/.env.local`.

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.

This repository (Asymmetric-al/core)

These Core instructions take precedence over the generic upstream guidance below. Reconcile them before running bun run skills:sync after an upstream refresh.

Triggers
  • Use ReUI for new pages, sections, and features that can reuse its components, examples, or Pro blocks; this repo expects substantial ReUI adoption.
  • Load for @reui registry installs, existing ReUI component work, ReUI MCP setup/debugging, and ReUI documentation or API research.
  • Pair with packages/ui/AGENTS.md, docs/ai/rules/frontend.md, the official .agents/skills/shadcn/SKILL.md, and docs/ai/skills/moai-library-shadcn/SKILL.md. ReUI does not replace those owners.
Workflow
  1. Read the nearest instructions and current source first. Verify packages/ui/components.json: exact base-maia, Base UI, Zinc-oriented semantic CSS variables, and iconLibrary: "lucide". Shared primitives stay in packages/ui; apps import @asym/ui. Adapt registry output to Core's Maia system before accepting it; preserve the reusable composition within that system. Do not run shadcn init, switch presets, introduce Radix, or fork shared primitives inside an app.
  2. Use the configured reui MCP for live discovery, APIs, and planning. Read its current tool schemas. get_project_context confirms style and license setup; a successful premium block search confirms plan access. Every MCP request requires an OAuth, personal-token, or license credential. Core's headless setup reads REUI_LICENSE_KEY from the process environment; never paste a secret into a committed file or command. See tools.md.
  3. Treat the account as Pro for discovery and installation entitlement. Verify repository visibility and source-distribution rights separately: Core is public and AGPL-3.0-only. The repository owner confirmed a separate agreement covering publication of Pro block source and modified derivatives here, including contributors; see docs/guides/development/reui-source-license.md for the recorded permission. Use suitable Pro blocks directly, alongside MIT public components, hooks, and examples with their notices. Keep commercial-source provenance distinct from MIT notices. Paid access alone does not establish distribution rights outside this confirmed scope; templates and Ultimate-only icons require their own applicable entitlement and permission. Use compose_page for full pages and scoped search for components/blocks. Motion Icons require Ultimate for discovery and install: use the existing lucide-react icons on Pro. Respect locked, unlock, weakMatch, and unavailableSections; do not invent missing inventory or promise an upgrade.
  4. Batch get_component for the APIs needed by an item, read omitted sections through the returned next hint, and copy worked get_examples composition. Confirm the API against already-installed source and current manifests before upgrading existing components: the live registry may be newer. Resolve API example imports against the actual shared source and public package exports; raw upstream paths may not match Core's installed owner. Use validate_usage for unfamiliar names/props. Documentation routing explains Base UI .md pages, llms.txt, setup, styling, RTL, and changelogs. Share an item's returned preview link and the relevant component docs link.
  5. Install only confirmed registry names into the shared UI package using Bun: bunx --bun shadcn@latest add @reui/<name> --yes --cwd packages/ui. Preview changes with --dry-run and inspect conflicts first. Never blindly --overwrite. Inspect registry files[].target and imports using CLI view/dry-run: explicit targets can create components/reui/* even though Core already owns the matching primitive under components/shadcn/* (for example components/shadcn/data-grid). Adapt that existing shared owner instead of introducing a duplicate tree. For genuinely new primitives or blocks, deliberately provide public @asym/ui exports and verify consumer imports; package aliases alone do not create exports. Keep the existing components.json aliases. packages/ui/components.json already has the authenticated @reui object with Authorization: "Bearer ${REUI_LICENSE_KEY}"; keep it. Free items also work through this config. The inherited shell key is usable; a key present only in root .env.local is not automatically loaded by the CLI running in packages/ui. If needed, use git-ignored packages/ui/.env.local. See rules/cli.md.
  6. Reuse existing shared UI before adding a duplicate. Keep DataTableResponsive from @asym/ui/components/shadcn/data-table for standard app tables. Use ReUI data-grid for a feature that needs its specific documented composition, integrated through packages/ui. Follow docs/guides/development/tanstack-virtual-foundation.md and the installed TanStack version; do not replace the shared table or apply an old v8 example to a v9 component. Keep data access in the existing API/database boundaries.
  7. Wire real typed data and all states; use documented Base UI render composition, Core semantic tokens, and shared motion/reduced-motion rules. New semantic status tokens belong in packages/ui/styles/globals.css, with purpose, light/dark values, Tailwind mapping, and contrast verification. Use TDD for substantive behavior, run the applicable package checks and browser/a11y checks, then the live get_audit_checklist plus Core gates.
  8. For skill maintenance, use references/upstream.md. Compare get_agent_skill.version with the pinned upstream version; stage the hosted bundle and reconcile Core overlays instead of executing the installer over this repository. Its direct writes bypass canonical source ownership.
Checklist
  • ReUI components/examples/Pro blocks considered before new custom UI
  • Current source, live API, returned item names, previews, and plan checked
  • Exact base-maia, Base UI, shared ownership, and semantic tokens preserved
  • Existing DataTableResponsive and data-access contracts preserved
  • Authenticated registry retained; license key stays outside tracked content
  • Source-distribution license verified separately from Pro authentication
  • MIT notices retained; restricted source omitted without covering agreement
  • Relevant TDD, package checks, browser/a11y checks, and audit gates passed
  • Skill refresh reconciled before running bun run skills:sync, followed by non-mutating bun run skills:verify

Naming: ReUI (@reui, this skill) is unrelated to shadcn-studio /rui (Refine UI) in docs/ai/rules/shadcn-studio-mcp.md.

ReUI for Agents

ReUI is a shadcn-compatible registry. It ships four things you reuse - never redesign:

  • components - the 24 ReUI building blocks with real APIs: data-grid, kanban, filters, date-selector, tree, stepper, ... (free)
  • examples - free c-* single-pattern use-cases of a component (c-kanban-1); install one and read it to see exact composition
  • blocks - premium full-page sections that compose components (data-grid-base-2, settings-2); Pro or Ultimate license at install
  • icons - Motion Icons in 4 styles, static + hover-animated variants; Ultimate license at install

The skill is free and this MCP is free to use; it just needs a ReUI account. On first use your agent opens a browser "Sign in with ReUI" prompt (a free account is created if you don't have one). Free covers components and examples with a daily request allowance; Pro unlocks premium blocks, Ultimate additionally unlocks Motion Icons, and either licensed plan removes the limit (see rules/registry.md). The same account and skill work in every agent and service the MCP connects to - this skill is agent-agnostic.

Skill + MCP are a team: this skill is the workflow (how to find, install, read the API, and adapt by reuse); the MCP is the live data and the hands (search, get_component, install commands). Your job: find the right item, install it with the shadcn CLI, read its real API, and adapt by reuse - wire real data and theme it; do not hand-roll or restyle what ReUI already provides. This skill layers on the shadcn skill: follow that for generic rules (spacing, cn(), semantic colors, forms); follow this for everything ReUI-specific.

The core loop (MCP-native)

  1. Find - call the ReUI MCP search tool with the user's intent. It returns a ranked, scored list across components/examples/blocks/icons, each with an install command, previewUrl, docsUrl, and componentsUsed. Pass hints (type, component, category, features, free) when you can infer them.
  2. Install - run the returned install command non-interactively: npx shadcn@latest add @reui/<name> --yes, with <name> exactly as a ReUI tool returned it. The CLI resolves deps, aliases, and the base/style from components.json. See cli.md.
    • The shadcn/ui components ReUI builds on (button, dialog, select, ...) are not ReUI items: install them by bare name, npx shadcn@latest add button --yes. A bare name in an item's registryDependencies is a shadcn/ui item.
    • badge and alert exist in both registries: @reui/badge is ReUI's, bare badge is shadcn's.
    • Templates are downloads from their page on reui.io, not shadcn add items.
  3. Read the API (on your base) - first note your base from components.json -> style (base-nova -> Base UI, radix-nova -> Radix UI). For each component an item uses, call get_component(name) and read its inline api (no web fetch); then get_examples(name) to install a worked example and copy its composition - the installed files are already in your base. Whenever you work with a component's API, also share its docsUrl (the primitive's API documentation page) with the user so they have the full reference. See components.md.
  4. Adapt (reuse-first) - swap demo data for real data, fix icon imports, align tokens. Do not redesign. See adapting.md.

Always show the preview. Every item a tool returns carries a previewUrl (a live preview page). Whenever you list, recommend, or present ReUI items to the user - blocks, components, examples, or icons, whether from search, search_icons, list_components, compose_page, or any getter - include each item's previewUrl so they can SEE it before installing. Blocks and examples open an individual live preview; icons and components link to their live category/component page. Never present an item without its preview link.

If the ReUI MCP is not configured, fall back to npx shadcn@latest search @reui -q "..." then add - but the MCP gives scored matches + inline APIs; prefer it.

Commands

Run ReUI as explicit slash commands (via the ReUI MCP) or just ask in plain language - both run the same workflow.

CommandInvokeDoes
build/mcp__reui__build <what>Compose a page/section/feature from ReUI: plan → install → read API → adapt → craft → audit.
add/mcp__reui__add <item>Find & install one component/example/block/icon and wire it in.
fix/mcp__reui__fix [target]Diagnose & fix ReUI usage: wrong/undocumented props, base/radix mismatch, missing states, a11y/scroll.
improve/mcp__reui__improve [target]Refine + extend existing ReUI UI to a production-exceptional bar (hierarchy, density, states, responsive, motion).

Invocation differs slightly per agent (/mcp__reui__build in Claude Code/Cursor/Windsurf, /mcp.reui.build in VS Code). No command surface? Just describe what you want - this skill drives the identical loop.

Can I use Reui in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Asymmetric-al/core --skill reui -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/reui, .gemini/skills/reui, .github/skills/reui and .opencode/skills/reui in your project.

What does Reui need to run?

Going by SKILL.md and its folder, Reui needs the command-line tools its instructions call (bun, npx and bunx) and credentials named REUI_LICENSE_KEY. Our summary lists: Node.js; A credential in REUI_LICENSE_KEY. Its frontmatter pre-approves these tools: Bash(npx shadcn@latest *), Bash(pnpm dlx shadcn@latest *), Bash(bunx --bun shadcn@latest *).

Does Reui access the network?

SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Reui safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Reui use?

Reui is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Reui use?

About 3.9k tokens (SKILL.md is roughly 16k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.7k tokens, read only when the agent opens those files.

What are the alternatives to Reui?

Skills that share tags, products or a category with Reui: Integrating shadcn/ui Components (google-labs-code/stitch-skills, 8.5k stars), UI UX Pro Max (saoudi-h/solar-icons, 190 stars), Activepieces Design System (activepieces/activepieces, 25k stars) and Uithing (BayBreezy/ui-thing, 729 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Reui?

Asymmetric-al (a GitHub organization) maintains it in Asymmetric-al/core, which has 381 GitHub stars. The repository holds 43 skills in this directory. The repository was last updated on October 9, 2026.
