Antigravity Skills UI Review
Overview
Part of StyleSeed, this skill audits UI code against the Toss seed's conventions instead of reviewing it as generic frontend work. It focuses on design-token discipline, component ergonomics, accessibility, mobile readiness, typography, and spacing consistency.
When to Use
- Use when a component or page should follow the StyleSeed Toss design language
- Use when reviewing a UI-heavy PR for consistency and design-system violations
- Use when the output looks "mostly fine" but feels off in subtle ways
- Use when you need a structured review with concrete fixes
Review Checklist
Design Tokens
- no hardcoded hex colors when semantic tokens exist
- no improvised shadow values when tokenized shadows exist
- no arbitrary radius choices outside the system scale
- no random spacing values that break the seed rhythm
Component Conventions
- uses the project's class merge helper
- supports
classNameextension when appropriate - uses the agreed typing pattern
- avoids wrapper components that only forward one class string
- reuses existing primitives before inventing new ones
Accessibility
- touch targets large enough for mobile
- visible keyboard focus states
- labels and
aria-*attributes where needed - adequate color contrast
- reduced-motion respect for animation
Mobile UX
- no horizontal overflow
- safe-area handling where relevant
- readable text sizes
- thumb-friendly interaction spacing
- bottom nav or sticky actions do not obscure content
Typography and Spacing
- uses the system type hierarchy
- display and headings are not overly loose
- body text remains readable
- spacing follows the seed grid instead of arbitrary values
Output Format
Return:
- A verdict: Pass, Needs Improvement, or Fail
- A prioritized list of issues with file and line references when available
- Concrete fixes for each issue
- Any open questions where the design intent is ambiguous
Best Practices
- Review against the seed, not against personal taste
- Separate stylistic drift from real usability or accessibility bugs
- Prefer actionable diffs over abstract criticism
- Call out duplication when an existing component already solves the problem

Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
