What This Skill Does

Target user

Frontend, product, and design-engineering teams using AI agents to implement or review UI changes.

Search intent

Learn how to package UI taste, responsive checks, accessibility expectations, and visual QA into a reusable skill.

Use When

  • An agent is implementing a UI change from a design, screenshot, product brief, or existing component pattern.
  • A team needs consistent visual hierarchy, spacing, responsive behavior, and accessibility checks.
  • A design review should produce concrete fixes instead of generic style advice.

Do Not Use When

  • The task is backend-only or has no user-facing interface.
  • The agent lacks access to the relevant design system or screenshots.
  • The workflow would override brand guidelines without product or design approval.

Required Inputs

  • Design brief, screenshot, Figma notes, or existing component reference.
  • Target routes/components and responsive breakpoints.
  • Design system tokens, icon set, and accessibility expectations.
  • Verification commands or browser screenshot procedure.

Expected Outputs

  • Scoped implementation or review notes tied to concrete UI elements.
  • Responsive and accessibility checklist results.
  • Visual QA notes with before/after observations when available.
  • Remaining design questions that need human input.

A frontend design skill gives an AI agent a reusable way to implement or review UI work against the product's actual design system.

The goal is not generic prettiness. The skill should protect workflow clarity, responsive layout, accessibility, brand consistency, and concrete visual QA evidence.

Frontend Workflow

Skill example

The agent should read the target route, nearby components, style system, and any design input before editing. It should then make scoped changes that preserve behavior and verify the result with lint, build, tests, and browser or screenshot checks when available.

For review-only usage, the output should identify specific layout, interaction, accessibility, or visual hierarchy issues rather than broad aesthetic opinions.

Skill Folder and SKILL.md Outline

Skill example

A good frontend skill points to design-system references and accessibility checklists instead of hardcoding a single visual style into every task.

The SKILL.md should emphasize constraints: use existing components, avoid new libraries unless approved, and verify the result on real breakpoints.

Suggested Folder Files

1

SKILL.md - UI workflow, design constraints, responsive checks, and output format.

2

references/design-system.md - typography, color, spacing, icons, and component rules.

3

references/accessibility-checklist.md - keyboard, contrast, semantics, and motion expectations.

4

templates/ui-review.md - structured visual QA report.

Illustrative SKILL.md outline

---
name: frontend-design
description: Implement or review frontend UI changes against the design system, responsive constraints, accessibility, and visual QA evidence.
---
1. Read the target route, component, design brief, and existing nearby patterns.
2. Preserve the product workflow and scope changes to requested UI behavior.
3. Check layout, hierarchy, spacing, text wrapping, keyboard access, contrast, and responsive breakpoints.
4. Prefer existing components and icon sets over new abstractions.
5. Report verification evidence and any design questions that need human input.

No unsafe executable examples

This outline is intentionally non-executable. Add helper scripts only after security review, provenance checks, and platform-specific permission review.

Platform Compatibility Notes

Skill example

Frontend skills often depend on local browser, screenshot, or design-file tooling. Those capabilities vary by platform and environment.

Document what the skill can do with only file access, and what requires browser automation, image generation, or external design integrations.

Platform Compatibility Notes

1

Claude Code: pair the skill with /run or /verify-style skills when live visual checks are available.

2

Codex: keep route-specific instructions in AGENTS.md and use the skill for reusable UI process.

3

OpenCode: use skill permissions to prevent broad access for experimental design helpers.

4

OpenClaw: ensure any screenshot or browser tooling required by the skill exists in the agent workspace or sandbox.

Governance Controls

Skill example

Design skills can change brand perception and conversion behavior. Treat major visual direction changes as product decisions, not implementation details.

For enterprise sites, the audit trail should include the input brief, modified components, verification commands, and any visual evidence captured during QA.

Governance Controls

1

Require human approval for brand, positioning, or conversion-copy changes.

2

Keep generated images and design assets traceable to their source.

3

Do not introduce new UI libraries without dependency review.

4

Log visual verification evidence for high-impact pages.

Quality Checklist

1

The UI preserves the primary user workflow.

2

Text wraps without overlap or clipping on mobile and desktop.

3

Controls are keyboard reachable and semantically appropriate.

4

Colors, icons, and spacing match the existing design system.
