ui-skills Gives AI Coding Agents a Machine-Readable Frontend Quality Standard
Frontend teams using AI coding agents now have a way to enforce consistent quality rules across every agent and every developer — catching accessibility gaps, layout jank, and metadata omissions before they reach production, without repeating the same feedback in every code review.
AI-generated frontend code routinely ships with broken accessibility, janky animations, missing metadata, and misused Tailwind utilities — not because models lack ability, but because they lack a definition of engineering-grade output. ui-skills fills that gap by packaging concrete, verifiable rules into a standard SKILL.md format that Claude Code, Cursor, Copilot, Windsurf, and other skill-protocol agents can load. Its four core modules cover baseline UI conventions, accessibility auditing, metadata completeness, and motion-performance constraints (only transform and opacity for animation, no reflow-triggering properties).
Each rule is binary and machine-checkable: `h-screen` is forbidden in favor of `h-dvh`, destructive actions must use `AlertDialog`, fixed elements must respect `safe-area-inset`. The audit output is a structured report with critical violations, warnings, and pass items, each accompanied by a code-level fix suggestion — designed to slot into PR checks, team review, and onboarding gates.
Installation is a single `npx ui-skills start` command, with options to init into a project or pull individual skills. The project treats frontend quality as a repeatable, automated checkpoint rather than a reviewer's recurring complaint, shifting human attention to architecture and business logic.
The project treats frontend quality not as a reviewer's judgement call but as a deterministic checklist — a shift that makes AI code review automatable in the same way linting is.
By targeting the SKILL.md protocol rather than a single editor, ui-skills positions itself as a portable quality layer that follows the developer across tools, instead of locking into one ecosystem.
The binary-rule design ("only transform and opacity") sidesteps the ambiguity that makes most prose style guides useless for LLMs — it converts taste into testable predicates.
