The 5 Best Design Skills for AI Agents in 2026

The five best design skills for AI agents in 2026 are Anthropic frontend-design, Impeccable, UI UX Pro Max, Taste Skill, and Vercel web-design-guidelines. For a new interface, start with frontend-design. To improve an interface that you already have, use Impeccable. To review UI code fast, use web-design-guidelines.

A design skill is an agent skill that teaches an AI coding agent how to design a user interface. An agent skill is a folder with a SKILL.md file. The file contains instructions, and the folder can also contain scripts and reference files. Claude Code, Codex, Cursor, and many other agents read the same Agent Skills format.

I chose these five skills from GitHub data and from the files in each repository. I read each SKILL.md file and README on 7 November 2026. I did not run a design test of the skills, so this list does not rank the quality of their output.

Compare the five design skills for AI agents#

This table compares the five skills on the data that I checked on 7 November 2026. Star counts change each day.

GitHub stars show interest, not quality. The counts for frontend-design and web-design-guidelines include all skills in their repositories.

1. Anthropic frontend-design: the best default for new UI#

Anthropic frontend-design is a design skill that gives an agent a design process for a new interface. Anthropic publishes the skill in its public skills repository under the Apache 2.0 license. The skill is one SKILL.md file with no scripts.

The skill tells the agent to work in two passes. In the first pass, the agent writes a short design plan:

• Color: four to six named hex values.
• Type: the typefaces and the role of each typeface.
• Layout: a layout concept, with short text and ASCII wireframes.
• Principles: the main rules that make this page different.

The agent then compares the plan with the brief. If a part of the plan looks like a default for any similar page, the agent changes that part. Only then does the agent write code.

The skill also lists five groups of traits that AI pages often share. One example is a cream background with a serif headline and a terracotta accent. Another example is a set of identical rounded cards with the same grey shadow. The skill sets a minimum quality level: mobile layouts, visible keyboard focus, support for reduced motion, and accessible color. It also gives rules for interface text, such as a button label that tells the user what the button does.

Limits: The skill has no checker. The agent must take screenshots itself to review the result. Anthropic says that the skills in this repository are for demonstration and education. Test them before you use them for important work.

Install it:

• In Claude Code, run /plugin marketplace add anthropics/skills. Then run /plugin install example-skills@anthropic-agent-skills. This plugin also installs 11 other example skills.
• In other agents, run npx skills add anthropics/skills --skill frontend-design.

Use it if you start a new page or app and you want the smallest skill with the lowest risk.

2. Impeccable: the best skill to improve UI that you already have#

Impeccable is a design skill that gives an agent named commands to change, review, and finish an interface. The Impeccable README says that the skill is strongest on interfaces that already exist. The license is Apache 2.0, and the SKILL.md file shows version 4.8.0.

Impeccable has 24 commands. One of them, craft, is an old name for a normal build request. The other commands are in five groups:

The init command asks about the product and writes PRODUCT.md. The document command records your current visual system in DESIGN.md. All later commands read these two files, so the changes stay on brand.

Impeccable also has a detector for generic design. The detector uses 62 fixed rules and does not use an LLM or an API key. You can run the detector in a terminal or in CI with npx impeccable detect src/. The command returns exit code 2 if it finds problems. The installer can also add a hook that scans each UI file that the agent changes.

Warning: Set IMPECCABLE_LIVE_COPY_AGENT=chat before you start live mode. Live mode can send text changes to the codex or claude command-line tool with approvals and the sandbox turned off. This occurs if no chat session asked for changes in the last minute, says the README.

Install it:

1. Open a terminal in the root folder of your project.
2. Run npx impeccable install.
3. Accept the design hook when the installer asks.
4. Start your agent again.
5. Run /impeccable init in your agent.

Use it if you have a page or a component and want to improve it in small, named steps.

3. UI UX Pro Max: the best data for design system choices#

UI UX Pro Max is a design skill that gives an agent a local library of design data that the agent can search. The UI UX Pro Max README lists this data:

• 80 searchable UI styles, of which 51 are active
• 192 product types, each with a color palette and design rules
• 74 font pairs
• 119 UX guidelines
• 22 technology stacks, which include React, SwiftUI, Flutter, and Jetpack Compose

The skill can make a design system for a request. The README shows an example for a spa landing page. The result has these parts:

• a page pattern and a visual style
• five colors and two fonts
• effects to use and patterns to avoid
• a checklist to use before delivery

The rules in SKILL.md put accessibility first, with a minimum text contrast of 4.5:1 and touch targets of 44 × 44 pixels or more.

The search scripts need Python 3. The README says that the scripts use only the Python standard library and make no network calls. The license is MIT.

Limits: The skill picks from a fixed data set. Two products of the same type can thus get similar palettes and fonts. If your brand needs a different identity, change the result before you build.

Install it:

• In Claude Code, run /plugin marketplace add nextlevelbuilder/ui-ux-pro-max-skill. Then run /plugin install ui-ux-pro-max@ui-ux-pro-max-skill.
• For other agents, run npm install -g ui-ux-pro-max-cli. Then run uipro init --ai claude, or use the name of your agent in place of claude.

Do not install the old uipro-cli package. The README says that its files are out of date.

Use it if you build for web, mobile, and desktop, or you need design choices for a product type fast.

4. Taste Skill: the best skill for company websites#

Taste Skill is a design skill that builds marketing websites for companies from starter files and fixed rules. The Taste Skill README shows version 2.5.0. The install name of the skill is design-taste-frontend, and the license is MIT.

Taste Skill uses a fixed process for each website:

1. The agent puts the business into one of six kinds: software, gaming, tech, product, service, or place.
2. A script picks a palette and a pair of Google Fonts for that kind of business.
3. A script picks one of 11 layouts for the hero, which is the top part of the page.
4. The agent starts from assets/starter.html, which shows one section on each screen at 1440 × 900 pixels.
5. Pages for shops, cafes, hotels, and services use real photographs from open archives, with credits.
6. Only software, tech, and gaming pages get WebGL effects. WebGL is a browser technology for 3D graphics.
7. A checker, check.mjs, opens the page in a real browser at several screen sizes. Each problem that the checker finds fails the page.

The skill needs Node.js 22 or later and Chrome, Edge, or Chromium. ffmpeg is optional. The skill needs no API keys.

Limits: Taste Skill is for company websites. Its description does not list dashboards or app screens. The skill folder has 1,617 files, so a full review before you install it takes more time than for the other four skills.

Install it: Run npx skills add https://github.com/Leonxlnx/taste-skill --skill "design-taste-frontend".

Use it if you build a company website and want a browser check of the result.

5. Vercel web-design-guidelines: the best skill for a fast UI review#

Vercel web-design-guidelines is a review skill that checks UI code against the Vercel Web Interface Guidelines. The skill does not design a page. It reads your files and gives a list of problems in file:line format.

The Vercel README says that the review covers more than 100 rules. The rules file has 17 groups. Some groups are accessibility, focus states, forms, animation, typography, performance, dark mode, and hydration safety. Three example rules are:

• Icon-only buttons need an aria-label.
• Never use transition: all.
• Honor prefers-reduced-motion.

The SKILL.md file has only 176 words and no scripts. At each review, the skill tells the agent to get the latest rules from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md.

Caution: Copy the rules file into your project if you need a fixed rule set. The skill gets the rules from a remote file at each review. If someone changes that file, the instructions to your agent also change.

Install it: Run npx skills add vercel-labs/agent-skills --skill web-design-guidelines -a claude-code. Use the name of your agent in place of claude-code.

Use it if you want a fast review of UI code before a merge.

Which design skills should you use together?#

Use one skill that designs and one skill that reviews. Each skill that designs has its own rules for type, color, and layout. If two of these skills match the same request, the agent can get two different sets of rules.

The context cost of each installed skill is small. Anthropic says that the agent loads about 100 tokens of name and description for each skill at the start. The agent loads the full SKILL.md body only when it uses the skill. Thus, all five skills add about 500 tokens at the start. This number is an estimate from the Anthropic figure, not a measurement.

How do you install a design skill safely?#

Install a design skill only after you read all of its files. A skill can contain scripts that run with your permissions. Anthropic advises that you use skills only from sources that you trust, and that you audit other skills fully before you use them.

Warning: Read each script in a third-party skill before you install it. A bad script can send your data out or get access to your system.

1. Open the repository of the skill.
2. Read the SKILL.md file.
3. Read each script in the skill folder.
4. Find each URL that the skill tells the agent to open.
5. Install the skill in one project first, not for all projects.
6. Use a fixed version, such as a Git tag, a commit, or a Git submodule.
7. Run the skill on a new Git branch.
8. Review the diff before you merge it.

In Claude Code, personal skills are in ~/.claude/skills/, and project skills are in .claude/skills/. The Claude Code skills documentation gives the full list of locations.

Other design skills to know#

Some other design skills are good for narrow jobs:

• GSAP skills: greensock/gsap-skills has eight official skills for the GSAP animation library, with 18,013 stars and the MIT license on 7 November 2026. Use them if your design uses GSAP for motion.
• Anthropic canvas-design: makes static visual art, such as posters, in PNG and PDF files.
• Anthropic theme-factory: applies one of 10 preset themes of colors and fonts to slides, documents, and HTML pages.
• Anthropic brand-guidelines: applies the Anthropic brand colors and typography. Use it as a model to write a skill for your own brand.
• Anthropic web-artifacts-builder: builds complex HTML artifacts for claude.ai with React, Tailwind CSS, and shadcn/ui.

The four Anthropic skills are in the same example-skills plugin as frontend-design.

Frequently asked questions#

Do design skills work in agents other than Claude Code?#

Yes. All five skills use the Agent Skills format, and each README gives install steps for more than one agent. The skills command-line tool from Vercel can install a skill into Claude Code, Codex, Cursor, OpenCode, and many other agents.

Does a design skill replace a designer?#

No. A design skill gives the agent rules and a process. A person must still decide the brand, the content, and the needs of the users, and must review the result.

How many design skills should I install?#

Install one skill that designs and one skill that reviews for each project. More skills that design can give the agent rules that do not agree. Remove a skill if you do not use it.

Are GitHub stars a good sign of quality?#

No. Stars show interest, not the quality of the output. Two of the counts in this guide also include other skills in the same repository.
