Build UI that fits the product instead of generic AI defaults. Use whenever building, designing, redesigning, restyling, polishing or reviewing screens, pages, components, flows or design systems, including requests like "make this UI better", "improve the UX" or "make it look less generic": work from the existing design system, design every state, check the rendered result, and look up real app and website references with the optional UXKIN MCP tools when a decision needs evidence.

UXKIN: real UI references for AI coding agents
Search real iOS app screens, complete user journeys and website design systems from Claude, Claude Code, Cursor, Codex, GitHub Copilot and any MCP client, so the UI your agent builds looks like a real product instead of AI defaults.
500,000+ real screens · 30k+ UI elements · 15k+ website design systems, each with a DESIGN.md

Ask a coding agent for a settings screen, a paywall or a landing page and it fills every gap with the most common choices: the same gradients, card grids and vague copy as everyone else. UXKIN gives it something better to work from: how real, shipped products handle the same screen or flow, and the actual colors, type and components of real websites.

npx skills add uxkin/agent
That installs all seven, or copy them into your agent's skills folder:
skills/no-ui-slop: how to build UI that
fits the product. Works on its own, with no account; with the UXKIN
server connected, it also tells your agent when to look up a real
reference.skills/uxkin-research: how to research
before designing: search the UXKIN library in plain words, open whole
journeys, compare several apps and report what they have in common.build-ui: a plan for each kind of UI
job (new screen, dashboard, polish, simplify, review), finished by
rendering at phone and desktop sizes, fixing and checking again.ios-screens: native iPhone UI in
SwiftUI, UIKit, React Native, Expo or Flutter, checked on small and large
iPhones, light and dark.design-md: reads your project and
writes (or updates) its DESIGN.md: colors with roles, type scale,
spacing, components and rules for agents.ui-from-screenshot: builds
a screenshot or mockup with your own components, then compares the result
with the image and fixes the differences.ui-states: finds and builds every
state of a screen (first use, empty, loading, error, offline, success)
and checks each one.All of them work on their own; with the UXKIN server connected they can
also look up real screens, flows and design systems. The plugins below
include no-ui-slop and uxkin-research; the other five install with
the command above (they live in .agents/skills).
The server is hosted at https://uxkin.com/mcp (Streamable HTTP). Most
apps sign in with your UXKIN account: no token to copy.
| App | How |
|---|---|
| Claude (web, desktop, mobile) | Open UXKIN in Claude's directory, click Connect, log in and click Allow |
| Claude Code | claude mcp add --scope user --transport http uxkin https://uxkin.com/mcp, then /mcp → uxkin → Authenticate |
| Cursor | One-click install on uxkin.com/cursor-ui-design, then Login next to uxkin |
| Codex | codex mcp add uxkin --url https://uxkin.com/mcp, then codex mcp login uxkin (or install the Codex plugin) |
| GitHub Copilot (VS Code) | Command Palette → MCP: Add Server → HTTP → https://uxkin.com/mcp, then sign in when asked (guide) |
| Lovable, Bolt, Devin Desktop | Add a custom MCP server with the URL above (Lovable, Bolt, Devin Desktop / Windsurf) |
| Any other MCP client | Add https://uxkin.com/mcp and sign in, or follow the setup at uxkin.com/docs |
Searching needs a UXKIN plan (Monthly or Lifetime). You can disconnect any app from your account.
Once connected, ask your agent things like:
| Tool | Returns |
|---|---|
find_ui_references | Real iOS app screens, user journeys (multi-screen flows like onboarding or cancelling a subscription) and websites |
find_ui_materials | Design systems from real websites: colors with their roles, typography, components, and the full DESIGN.md for the top match |
get_journey | Every screen of one journey, in order |
list_collections / get_collection | The references you saved into collections on uxkin.com |
All tools are read-only.
It also offers ready-made prompts your app can show as commands (in
Claude Code: /mcp__uxkin__research_flow and so on):
| Prompt | What it asks your agent to do |
|---|---|
research_flow | See how real apps handle a flow (onboarding, checkout, paywall…) and recommend one |
find_design_system | Find real website design systems that fit your product and mood |
review_my_ui | Compare a screen in your project with real apps and suggest fixes |
build_from_collection | Start from references you saved on uxkin.com |
no-ui-slop and uxkin-research skills (skills). The five other skills are installed separately with npx skills add uxkin/agent..claude-plugin),
Cursor (.cursor-plugin) and Codex
(.codex-plugin), the Kiro power (POWER.md),
the Google Antigravity plugin
(plugin.json) and the Gemini CLI extension
(gemini-extension.json): the skill and the MCP
server in one install.server.json), published to the
official MCP Registry.DESIGN.md): UXKIN exports a
DESIGN.md for every website in its library, and UXKIN itself is built from
one. Hand it to your agent to see the format in action.DISTRIBUTION.md): every
registry, app store and directory, and where each one stands.examples): config files for each app, project
instructions for your AGENTS.md or CLAUDE.md, example prompts, and
worked examples (account deletion, subscription cancellation, mobile
onboarding) showing what an agent does differently with UXKIN.One install adds the skill and the UXKIN server. The skill works right
away; to search the library, connect the server (Claude opens a UXKIN page
where you log in and click Allow). In Claude Code, type /mcp, pick
uxkin and choose Authenticate.
In Claude Code you can also add it from GitHub directly:
claude plugin marketplace add uxkin/agent
claude plugin install uxkin@uxkin
After installing, click Login next to uxkin in Cursor's MCP settings, log in to UXKIN and click Allow.
codex plugin marketplace add uxkin/agent
codex plugin add uxkin@uxkin
codex mcp login uxkin
The last command opens a UXKIN page where you log in and click Allow.
git clone https://github.com/uxkin/agent uxkin
agy plugin install ./uxkin
Then type /mcp, pick uxkin and choose Authenticate: a UXKIN page
opens where you log in and click Allow. To add only the server, put
mcp_config.json in ~/.gemini/config/mcp_config.json.
In Kiro, open the Powers panel → Add Custom Power → Import power
from GitHub, and enter https://github.com/uxkin/agent. When Kiro asks
to authenticate uxkin, click Authenticate, log in to UXKIN and click
Allow.
gemini extensions install https://github.com/uxkin/agent
Then start Gemini CLI and type /mcp auth uxkin: a UXKIN page opens where
you log in and click Allow.
The skill runs locally and sends nothing. The MCP server receives only the search text your agent sends (for example "onboarding for a meditation app"), the result limit and your sign-in, and returns matching references from uxkin.com. It doesn't read your code, files or conversation. See the privacy policy.
Fixes to the skill, setup steps and examples are welcome: see CONTRIBUTING.md. To report a security problem, see SECURITY.md.
The skill and the files in this repository are MIT licensed. The UXKIN library itself (its screens, journeys and design systems) is a hosted service, not part of this repository: see the terms. The MIT license covers the code and text here; it doesn't grant use of the UXKIN name or logo.

Install via CLI
npx mdskills install uxkin/no-ui-slopUXKIN is a free, open-source AI agent skill. Build UI that fits the product instead of generic AI defaults. Use whenever building, designing, redesigning, restyling, polishing or reviewing screens, pages, components, flows or design systems, including requests like "make this UI better", "improve the UX" or "make it look less generic": work from the existing design system, design every state, check the rendered result, and look up real app and website references with the optional UXKIN MCP tools when a decision needs evidence.
Install UXKIN with a single command:
npx mdskills install uxkin/no-ui-slopThis downloads the skill files into your project and your AI agent picks them up automatically.
UXKIN works with Claude Code, Claude Desktop, Cursor, Vscode Copilot, Windsurf, Continue Dev, Gemini Cli, Amp, Roo Code, Goose. Skills use the open SKILL.md format which is compatible with any AI coding agent that reads markdown instructions.
