UX/UI Agent Skills
UX/UI Agent Skills is a project-level instruction and reference kit that gives a coding agent a structured way to plan, build, review, and test interface work.
Its request router connects design-token files, component specifications, accessibility guidance, visual-taste references, framework adapters, runnable skills, validation scripts, and a product starter without adding a user-facing app runtime. Use this as a first read, not a recommendation. Open the original project before trusting details like terms, limits, privacy, cost, setup, or safety.
What it is
Design knowledge installed with the project
The kit copies instructions, rules, skills, design references, templates, and helper scripts into a project so Claude can load the relevant layer when a design request arrives.
Why it stands out
A connected project design system
It joins DTCG-style tokens, component states, accessibility guidance, UX writing, framework adapters, named design-system references, and reusable project rules instead of treating interface polish as one prompt.
Availability
Choose the integration route
The repository declares MIT and provides plugin, project-file, CLI and MCP routes. Claude Code, AGENTS.md-based clients such as Codex and Cursor, and the Gemini routes have different integration features. See the repository for current terms.
Why it matters
What makes it useful
Interface work can drift when every request starts from a fresh prompt. Because this kit lives with the project, Claude can reuse its design decisions and workflow instead of rebuilding the brief for every component or review.
What to know
Where it fits
Use it when a coding agent is helping build or review a website, app, component library or design system. The Claude Code plugin supplies skills, hooks and a critic. The AGENTS.md route supplies project guidance and gates without those Claude-specific mechanisms. Gemini CLI has an extension or project install using GEMINI.md and ported skills; the Antigravity route uses the same project files. Those routes omit the Claude-only critic, observe report and project scaffold, and do not install automatic hooks. MCP exposes the checks to a compatible client, so reading design rules and actually running checks remain separate steps.
Notable points
What stands out
The kit separates a check result from a completed review. Its automated checks cover defined requirements such as token validity, contrast, keyboard operation and responsive behavior; rendered critique challenges design quality. Its MCP server distinguishes a measured pass, a measured failure and an inability to inspect. The plugin also records session and UI-edit activity for its observe report, including work that ended with pages unmeasured. This gives a developer something concrete to examine when an agent says the interface is ready; it does not establish that the interface is usable or well designed.
Before using
What to review
Use the installer's dry-run option before writing into an existing project, then review the files it will add or replace. The force option can overwrite existing kit files.
Choose the installation route for your client. The documented AGENTS.md route does not install Claude hooks; those checks run when you invoke them. Review project instructions and existing files before installing.
The knowledge layer does not add an app runtime, but its tools still have requirements: the npm package and JavaScript checks need Node 20 or newer, Python validators need Python 3, and render-based gates need the project's Playwright and browser setup.
Review the installed instructions, runnable scripts, shared permission settings, and optional project connections before letting an agent use them in a real codebase.
The included Figma connection expects an environment-supplied API key. Keep that secret outside the repository and leave the connection unused when it is not needed.
When upgrading from 2.x, review the 3.0 release migration table: ten short token names have been removed from generated CSS. Existing pages that still use those names need the replacement variables.
The npm package carries an index of design-system references and fetches a selected reference when needed, checking its SHA-256 against that index. Plugin installs and Git clones carry the references locally. Choose the route with those download and storage differences in mind.
The installation guide says an individual render gate can print SKIPPED and exit successfully without a browser. It recommends DS_REQUIRE_BROWSER=1 when relying on the exit code; the gate.mjs wrapper sets that requirement itself. A skipped measurement is not a passing check.
The release notes report Gemini CLI installation checks, but Antigravity has not been tested end to end. Check the documented client requirements rather than assuming the same behavior across assistants.
The observe release notes describe local session records, automatic removal after 30 days and a DS_OBSERVE=0 opt-out. Review those controls if you use the plugin hooks.
Treat the named design-system library as guidance, not proof of affiliation or a substitute for the project's own brand and product decisions.
Run the project's gates, then use human review and test the actual interface with real content, keyboard use, assistive technology, zoom, text scaling, reduced motion, and narrow screens. Instruction files cannot guarantee the finished product is accessible, usable, or well designed.
Reader fit
Who may find it relevant
Designers and developers using Claude to build interfaces or maintain a design system.
Teams that want token, component, accessibility, review, and code-generation rules to live with the project.
Less relevant for someone looking for a visual drag-and-drop editor or a finished component library to import. Teams using another coding assistant should inspect the AGENTS.md or MCP route and its limits.
Editorial note
Why LifeHubber lists it
We list UX/UI Agent Skills because it connects reusable design decisions with checks on the interface an agent produces. A team carrying the same colour, component-state and accessibility requirements across several screens can keep that guidance with the project and examine the resulting work against it. That connection makes the kit worth exploring when a good-looking first draft still needs to become a consistent interface; measured checks and human critique each have a part in that decision.
