Claude Frontend Design Skill: How It Works and Alternatives

The Claude frontend design skill is a single markdown file in Anthropic's skills repository that tells Claude how to design a page with a point of view, not with the usual defaults. You install it with /plugin marketplace add anthropics/skills and the example-skills plugin. It is free to download, it ships no scripts, and we read it in full on 12 November 2026 but have not run it.

What the skill is

Anthropic keeps a public repository of example skills, and Frontend Design is one folder in it. The folder holds two files: SKILL.md and a LICENSE.txt. There is no code to run and nothing to configure. The description in the file says it is guidance "for distinctive, intentional visual design when building new UI or reshaping an existing one", covering aesthetic direction, typography and avoiding templated defaults.

That makes it a different kind of thing from a design system or a component library. It does not give Claude a palette, a font list or a set of components. It gives Claude a way of thinking about the job, plus a list of habits to avoid. If you are new to the format, our skills guide explains how a skill is loaded and why a folder with one file is cheap to carry.

Our entry for it is Frontend Design. The wider shortlist is in best Claude skills.

What the file tells Claude to do

We read the whole SKILL.md. It is short, and most of it falls into five instructions.

1. Start from the subject, not from a template

The file opens by telling Claude to act as the design lead at a studio known for giving each client a distinct identity. If the brief does not say what the product is, Claude is told to work it out first and confirm with you: one concrete subject, the audience, and the page's main job. The reasoning given is that the subject's industry, materials and vocabulary are where distinctive visual choices come from. A toy for eight-year-olds and a dashboard for financial analysts should not look alike.

2. Treat the hero and the type as the personality

For web pages the file says to open with the most characteristic thing in the subject's world: a headline, an image, an animation, a live demo. It calls a big number with a small label and a gradient accent "the default treatment", and says to use it only if it is truly the best option.

On type, it asks for one family or two, and if two, clearly different. It tells Claude to choose typefaces deliberately, to set a type scale following The Elements of Typographic Style, and to keep line lengths under 80 characters. Serif body text can run a little longer and wants slightly more line height.

3. Avoid the tells of a generated page

This is the part people quote. The file names three typographic habits as the commonest tells:

• accenting a single word or phrase in a headline with italics, bold or a colour
• using all caps for labels
• adding unnecessary labels above content

It also says numbered markers like 01, 02, 03 are only right when the content really is a sequence, and that motion should be sparing: one orchestrated page-load moment beats fade-and-slide entrances on every section and hover effects on every card. Motion that answers a person's action is welcome.

4. Know what generated design looks like right now

The file lists five clusters it says AI design currently falls into. We paraphrase them here:

It is careful to say none of these is banned. The brief always wins, including when the brief asks for one of them. The rule is that where you leave an axis free, Claude should not spend that freedom on a default. The file even flags that the clay-orange accent it mentions is Anthropic's own Claude colour, so on someone else's brief it reads as a tell.

5. Plan, review against the brief, build, then critique

The process has two passes. First Claude writes a compact plan with four to six named hex colours, the typefaces and their roles, a layout idea described in a sentence or an ASCII sketch, and the principles that make the page unique. Then it reviews that plan against the brief, and revises any part that reads like what it would produce for any similar page. Only then does it write code.

The closing sections ask for restraint ("spend your boldness in one place"), a quality floor of responsive layout, visible keyboard focus, reduced motion respected and accessible colour, and a screenshot review if the environment allows it. A final section covers interface copy: active voice, buttons that name what they do, errors that explain the fix.

How to install it

The repository's README gives the Claude Code route. Frontend Design is bundled in the example-skills plugin along with eleven other skills.

/plugin marketplace add anthropics/skills
/plugin install example-skills@anthropic-agent-skills

You can also pick plugins through the interactive menu after adding the marketplace. Installing example-skills brings in every skill in that bundle, not only this one. If you want just the design skill, copy the skills/frontend-design folder from the repository into your own skills directory instead.

After it is installed, the README says you use a skill by mentioning it, so ask for the design work and name the skill in your request. Whether Claude loads it unprompted depends on how closely your request matches the description, so naming it is the reliable route.

Getting good results from it

The skill is instructions, so the quality of the output depends mostly on the brief you give it. These habits follow directly from what the file asks for.

1. Give it the subject. Say what the product is, who it is for and what the page must get them to do. The skill tells Claude to ask or propose one if you do not, but a clear answer from you saves a round trip.
2. Name the direction if you have one. The file says the brief's own words always win. If your brand has a palette and a typeface, state them. Frontend Design is built to open the field, not to fight a fixed identity.
3. Ask to see the plan first. The process starts with a written token plan. Ask Claude to show it before building, then correct it. A palette change costs one sentence at that stage and a rewrite later.
4. Ask for a screenshot critique. The file recommends taking screenshots to review. If your agent can drive a browser, ask for a desktop and phone capture of the result and a list of what Claude would change.
5. Keep real content in. The skill tells Claude to build with the brief's real content throughout. Paste actual copy and numbers, not lorem ipsum, because the design is supposed to be specific to them.

Where it stops

A single markdown file has limits, and the README of the repository does not claim otherwise.

• It does not enforce anything. The skill advises. There is no check that the finished page avoids the tells it lists, so it is worth a review pass.
• It is not a design system. It will not give two pages on the same site the same tokens unless you carry the plan between sessions. If you need consistency across a product, keep a design file and refer to it.
• It targets new design. The description says new UI "or reshaping an existing one", but a mature codebase with its own components will pull the agent toward what is already there.
• The listed tells will date. The file describes what generated design looks like now. As models and prompts change, so will the clusters. Treat the list as a snapshot.
• It uses your plan. Planning, reviewing and critiquing are extra work for the model, so a design task runs longer than a plain "build this page" prompt.

Six alternatives and companions

Frontend Design is the lightest of the design skills. The others add rules, data, checks or a process. All of the facts below come from each project's README and licence file, which we read on 12 November 2026.

UI UX Pro Max

UI UX Pro Max works the other way round from Frontend Design. You describe the project, and its design system generator reasons over 192 industry rules to recommend a page pattern, a visual style and a palette before any code is written. It installs as a Claude Code plugin or through its own command line tool. Pick it when you want a direction handed to you. Skip it, or give it your identity first, if the brand already exists.

Impeccable

Impeccable is a reviewer more than a generator. It has commands such as polish and bolder to steer a result, critique to score against usability heuristics, and audit to check accessibility, performance, theming and responsive behaviour with severity-ranked findings. A detect command scans for common AI design patterns. It pairs well with Frontend Design: one builds, the other checks.

Taste Skill

Taste Skill aims at company websites that look art directed. It needs Node 22 or newer and a local Chrome, Edge or Chromium. It suits a launch page where the site is the product, and it is heavier to set up than a single markdown file.

UI Craft

UI Craft builds a surface such as a dashboard against a 10-item acceptance bar, and adds critique, polish and animation commands. Its README warns that a globally installed skill may not be read by Claude Code, so install it per project or use the plugin.

Anti Slop

Anti Slop is the closest in spirit to the "avoid the tells" half of Frontend Design. Its README calls it a filter, not a style guide: it prescribes no colours, fonts or layouts, and for UI you intend to ship it expects direction to come from a design file you provide. Use it when you already know where you are going.

Web Quality Skills

Web Quality Skills does not design anything. It measures, with Lighthouse and the Chrome DevTools MCP server, and fixes performance, accessibility and SEO. It is a good last step after any of the design skills, because attractive and slow is still slow.

More are listed under frontend and UI.

Which to pick

You can combine them, but not all at once. Two skills that both set a direction will pull the agent two ways. A sensible stack is one that decides (Frontend Design, UI UX Pro Max or Taste Skill), one that reviews (Impeccable or Anti Slop), and Web Quality Skills at the end.

Before you install any of them

• Licence. Read the licence file, not only the badge. Anthropic's example skills carry a LICENSE.txt in each folder, and the one for this skill is Apache 2.0. Several others are MIT.
• Piped installers. Some projects offer a one-line installer that downloads and runs code. Clone and read it first.
• Hosted services. Check whether the skill sends your project to a third party or asks for an API key.
• Where it installs. A skill in the wrong folder is silently ignored. Run a small request that names the skill and check that Claude mentions it.
• Scope. Install into one project and try it on one page before you make it global.

Our take

Frontend Design is the right first skill for most people. It costs nothing, has nothing to configure, and what it asks for is sound advice a human designer would also follow: know the subject, choose type deliberately, spend boldness in one place, and review your own plan before building. Its list of generated-page tells is useful even if you never install it, because it gives you words for what looks off.

Its weakness is that it is advice, with nothing behind it to check the result. For a one-off page that is fine. For a product with many screens, pair it with a reviewer such as Impeccable and keep a short design file that holds your tokens. We have read these skills closely but not run them, so test any of them on a real page of yours before you rely on it.
