What it does
Design Skills for AI Agents gives an agent knowledge of established design and UX methods. The set has ten skills: UX research, interface critique and evaluation, WCAG 2.2 accessibility audit, journey mapping, design systems, UX strategy, interaction design, design ops and handoff, UX writing and design elevation. Every skill has the same layout: a main `SKILL.md` that works on its own and `references/`, `templates/` and `examples/` folders with depth on demand. Interface critique follows a nine-step framework with Nielsen's heuristics and 27 UX laws, and the accessibility audit passes five layers: automated, keyboard, screen reader, visual and flow.
Who it is for. Designers and developers with no dedicated UX researcher who want an agent partner for interface critique and accessibility checks.
Good fit when
- A mockup or finished screen needs review against heuristics and UX laws with problem severity.
- Before release accessibility is checked against WCAG 2.2 and fix code is requested.
- User interviews need a script, a usability test plan and a way to analyse the answers.
- Error and hint texts need rethinking from a UX writing standpoint.
Not a fit when
- You need a replacement for live research: the skills help plan and analyse but do not replace talking to users.
- You need a ready component library: the design systems skill gives knowledge and templates and contains no components.
- You need one narrow tool: a set of ten skills is broader than the task.
Example request
Critique this checkout screen against Nielsen's heuristics and list the problems by severity.Limitations
The skills provide knowledge and methods, and judgement stays with you: automated accessibility auditing finds only some problems and the rest is checked by hand. The volume is large: reference folders hold ten to twenty files per skill and the agent loads them as needed. All ten skills install as a single Claude Code plugin, which namespaces them under `design-skills:`. Individual skills are chosen with the `--skill` flag. The latest commit is from September 2026.
How to disable. Run `/plugin uninstall design-skills` if you installed the plugin or delete the skill folders from the agent's skills directory. For a global `npx skills` install use `npx skills remove`.
FAQ
How do I install all ten skills?
With `npx skills add cuellarfr/design-skills`. The installer detects your agents and lets you choose skills. For Claude Code there is a plugin route through `/plugin marketplace add cuellarfr/design-skills`.
What does the accessibility audit include?
Five layers: automated check, keyboard, screen reader, visual review and flow. The skill finds issues, rates severity, gives fix code and builds a report from a template.
What laws and heuristics does the critique use?
Nielsen's heuristics, 27 UX laws by domain, interaction design principles, information architecture evaluation and UX writing review.
How do I install a single skill?
With the `--skill` flag, for example `npx skills add cuellarfr/design-skills --skill design-critique`.
Which agents does it work with?
Claude Code, Cursor, Codex, OpenCode and more than forty other agents supported by the `skills` installer.
