Build, refactor, and review frontend UI in any framework — components, accessibility, forms, client state and data fetching, responsive layout, performance, client-side security/PII, and UX/visual design (design plan, tokens, typography, color, spacing, motion). Use whenever the task touches the UI layer: creating or changing a component, page, or screen; designing a site, landing page, or product surface from scratch; styling or theming; accessibility/a11y; forms; client state…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Building Frontend UI

A frontend change is good when it **reuses what already exists**, is **accessible by default**, **handles every state** (loading, error, empty, long content), **performs** under real data, and **leaks no data** to the client. This skill is framework-agnostic: the workflow and rules live here; framework-specific mechanics live in `references/<framework>.md` and are loaded only when relevant.

## Read first (always)

List `learnings/` and read every file relevant to the current task — project conventions, the design system, banned dependencies, and component patterns live there and override the defaults in this file. If a learning conflicts with this skill, **the learning wins** — mention it.

## Starting from zero?

How to install

The exact contents, by fingerprint
mdr add cristhianzl/claude-skills-czl/building-frontend-ui@sha256:5de7ca98d56f7a7b

The line at the top of this page pins the label git:20260910.da1e5c5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
