Best Frontend Design Skills for Claude Code and Codex

The best frontend design skill depends on what you want the agent to get right: a distinctive look, accurate component code, accessible markup or a finished artifact. This guide sorts the directory's design skills by that job, so you can choose one or two instead of reading a long list. Every pick has a "best for" line, requirements, a licence as the directory records it, and a trade-off.

Descriptions come from each skill's SKILL.md and repository, plus the directory's design systems and accessibility topic hubs. The editorial team did not run these skills to compare output, so there are no claims about how good the designs look. What follows is what each skill tells the agent to do.

Quick picks by job

Frontend design skills that set direction

These three tell the agent how to think about a design, not which library to import. They fit new pages and redesigns.

anthropics/frontend-design

Best for: landing pages and interfaces that should not look templated.

anthropics/frontend-design is published by Anthropic and lives in the skills repository. It asks the agent to pin down what the product is, who the audience is and what the design's job is before choosing visuals, then to draw choices from the subject's own world. It covers the hero section and typography, including how many families to use, a deliberate type scale and line lengths, and it names default treatments that signal a generated page. The only bundled file is a licence.

Requirements: none beyond the agent.

Trade-off: it is guidance only. It will not set up a framework, install components or check accessibility for you. The directory records Apache-2.0 and its automated check passed.

nutlope/hallmark

Best for: avoiding the generic AI look, and auditing or redesigning an existing page.

nutlope/hallmark is licensed MIT. It stresses structural variety, so two pages for different briefs do not share the same hero, three-feature and footer rhythm. Explicit verbs change behavior: an audit scores a target against an anti-pattern list and returns a ranked punch list without editing anything, and a redesign keeps content, routes and component ownership while replacing the visual structure. Most of the folder is reference material, including a component cookbook.

Requirements: none listed.

Trade-off: a redesign changes the visual layer, so review the diff on a production site. The automated check passed.

monoscope-tech/impeccable

Best for: polishing and critiquing a working interface across layout, type, color, motion and accessibility.

monoscope-tech/impeccable is licensed Apache-2.0. It organizes work as verbs such as design, critique, audit, polish, harden and adapt, with a reference file for each. Each session starts by running a bundled launcher that loads product and design context files. The skill asks for a bounded finish: one batched inspection of desktop and mobile, one batch of fixes and at most one more round.

Requirements: permission to run the bundled launcher, which is a self-contained binary that ships with the skill or is downloaded on first run.

Trade-off: running a binary the skill may download is a bigger approval than reading text, so read how it is fetched before agreeing. It is not meant for backend-only work. The automated check passed.

A design knowledge base the agent can search

Best for: choosing a style, palette and font pairing, and checking a UI against UX rules.

nextlevelbuilder/ui-ux-pro-max is licensed MIT. It bundles a local database of styles, product palettes, font pairings, UX guidelines, icons, chart types and notes for many technology stacks, stored as CSV and JSON files the agent searches by domain. Its rules are ranked by priority, starting with accessibility and touch targets, then performance, layout, typography, color and animation. Backend logic and other non-visual work are out of scope.

The repository README lists a wide set of supported agents, including Claude Code, Codex CLI, Cursor, Gemini CLI and GitHub Copilot, and mentions a command-line installer and a Claude Code marketplace route. It says Python 3 is a prerequisite.

Trade-off: a large database gives the agent many options, and that choice can pull toward a generic median unless you give it a clear brief. The automated check passed. The directory also lists a similarly named variant from another author, so check the owner in the link before installing.

Component and design system skills

These tie the agent to a stack, which is what you want once the design direction is settled.

• oss-apps/shadcn (MIT) runs the shadcn CLI through the project's package runner, reads the project with shadcn info --json, searches registries before writing custom UI, and applies rule files with correct and incorrect examples for Tailwind classes, forms and composition. It needs a project with a components.json file, or one to initialize. Trade-off: it assumes you are committed to shadcn/ui.
• nextlevelbuilder/ui-styling (MIT) combines shadcn/ui, Tailwind CSS and a canvas layer for posters and brand material. It targets React frameworks including Next.js, Vite, Remix and Astro. It needs Node.js with npx and a React project. Trade-off: the canvas fonts it bundles come with their own licence texts, so check them if you redistribute.
• chakra-ui/chakra-ui-builder (MIT) reads package.json first to match the Chakra version and framework, then covers setup, forms, dashboards, color mode, tokens and recipes. It needs a React project with the Chakra and Emotion packages. Trade-off: it targets Chakra v3, and the same owner lists separate skills for migrating from v2.
• nextlevelbuilder/design-system (MIT) defines primitive, semantic and component token layers, exports CSS variables, and scans source for hardcoded values that should use tokens. It also generates slides from the same system. It needs Node.js for the token scripts and Python for the slide scripts. Trade-off: it asks you to adopt its token structure rather than reading yours.

All four passed the directory's automated check.

Accessibility and motion skills

ibelick/fixing-accessibility (page, MIT) is best for catching accessibility problems with small changes. Given a file, it reports each violation with a line, a one-sentence reason and a code-level fix. Rules are grouped by priority: accessible names, keyboard access and focus handling rate as critical, ahead of semantics, forms, contrast and motion. It needs nothing installed. Trade-off: it reviews code, so it will not replace testing with a real screen reader. The automated check passed.

baptistearno/web-animation-design (page) is best for choosing easing and timing. It draws on Emil Kowalski's Animations on the Web course and presents reviews as a single before-and-after table. Its description is specific: elements entering or leaving use ease-out, and anything users see a hundred or more times a day should not be animated. Trade-off: the directory lists its licence as a licence file that does not match a standard licence, so read it on GitHub first. The automated check passed.

More accessibility-related skills are in the accessibility topic.

A skill for finished artifacts

Best for: turning a multi-component React prototype into one shareable HTML file.

anthropics/web-artifacts-builder is official and listed under Apache-2.0. A setup script scaffolds a React, TypeScript and Vite project with Tailwind and a set of shadcn/ui components, and a bundle script uses Parcel and html-inline to produce one file with everything inlined. It needs Node.js 18 or later and Bash. Trade-off: it is a build pipeline for claude.ai artifacts, so it is the wrong tool for a production app. The automated check passed.

How to install a frontend design skill

Copy the skill folder where your agent scans for skills, or use the agent's plugin or CLI route. Steps differ by agent, so follow the pages for Claude Code and Codex. The Claude Code install guide explains personal and project scope.

A sensible starting stack is one direction skill, one stack skill matching your component library, and the accessibility skill. To see how skills are structured before you add several, read the SKILL.md format reference. For other document and file jobs, see the guides to PDF skills and slides skills.
