Frontend Design

What it does

Frontend Design is a set of instructions for the agent making an interface, rather than a theme, component library or drag-and-drop editor. Its value is in making decisions specific to the product: what should attract attention, how text should sound, which visual references fit the audience and which decorations can be removed. The source asks for a design plan before implementation and a critique afterwards. It can guide a new landing page or reshape an existing screen while preserving the project’s technical constraints.

When to use it

• A product page works technically but looks interchangeable with dozens of generated sites. Use the skill to establish a visual direction grounded in the actual product, audience and content.
• An existing dashboard has inconsistent type, spacing and hierarchy. Ask for a coherent system while keeping the current components, data flow and primary tasks.
• A campaign needs a memorable first screen. Ask the agent to identify one distinctive focal point rather than adding effects to every section.

Step-by-step workflow

1. Define the brief: product, primary audience, main user action, existing brand rules, real copy and technical restrictions. If these are missing, resolve them before choosing a look.
2. Propose a compact design system: four to six named palette values, font roles, a type scale, alignment, spacing principles and a layout sketch. Explain why those choices fit this subject.
3. Compare the plan with the brief. Remove decisions that could have been copied unchanged into an unrelated project. A requested visual style takes precedence over the skill’s default preferences.
4. Implement the approved direction in the existing stack. Keep CSS specificity predictable, use real content and spend visual emphasis on the element that matters most.
5. Inspect the rendered result. Check mobile wrapping, readable line lengths, visible keyboard focus, reduced-motion behavior and spacing. Remove decoration that contributes no information.

Example request

Use frontend-design to redesign IDAKIM Digital’s Agent Skills directory for independent developers choosing Claude Code and Codex workflows. Keep English content, existing URLs and semantic HTML. The main action is opening a detailed guide. First propose a palette, type scale and layout with reasons tied to this audience. Preserve the current stack; add no UI framework. Build the directory and one detail page with realistic content. Verify at 390px and 1440px, including keyboard focus and long skill names. Explain which generic treatments you removed and why.

Worked example

For a language-learning dashboard, start with the learner’s next useful action: continue today’s lesson. Put that action ahead of streaks and promotional cards. Use lesson titles and progress states that fit adult beginners, establish a readable text hierarchy and choose one motivating visual feature. After implementation, compare the first screen with the brief: can a returning learner identify the next lesson without scanning the entire page? This is an editorial example of applying the workflow, not a claim that the skill includes a prebuilt language-learning template.

What you get

A tailored UI implementation with an intentional visual direction.

How to evaluate the result

• Request the design plan plus the actual modified files; a mood board alone is not a working interface. Expect reusable CSS values or the project’s existing design tokens, responsive layouts and a short account of the decisions.
• Open the page at a narrow viewport. Check long headings, navigation, content order and horizontal scrolling. Use Tab to reach the main actions and confirm the focus indicator remains visible.
• Check empty, loading and error states where relevant. Ask for screenshots of the rendered implementation; a description of what the page should look like cannot establish what it actually renders.

What you need

A frontend project, clear audience and permission to edit the relevant files. A browser is useful for checking the result.

Setup and activation

The publisher README documents Claude Code’s anthropic-agent-skills marketplace and its example-skills plugin. After reviewing the selected source and bundled files, enable the appropriate plugin in your client and mention the skill by name. Keep the complete skill folder so relative references still resolve. Plugin availability and commands depend on the client version; the publisher README is linked below. This page installs nothing. Before local installation, review and security-scan the exact source/version; catalogue inclusion is not security approval.

Limits and considerations

Choose a testing skill for a broken button, a guidelines audit for specific accessibility findings, or a performance skill for slow loading. Frontend Design can help those projects visually, but it does not supply browser measurements, certify accessibility or demonstrate improved sales. Avoid asking for a full redesign when a small layout fix solves the problem.

Related workflows

• Pair with Web App Testing to exercise the resulting UI.
• Pair with Web Design Guidelines to review interaction and accessibility details.
