Practitioner-grade frontend reference: HTML semantics, CSS tokens, Tailwind, WCAG 2.1 AA, Core Web Vitals, asset optimization, framework-agnostic JavaScript. Activate when authoring or reviewing HTML, CSS, Tailwind config, accessibility audits, performance budgets, or framework-free UI work.
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
# Frontend Practitioner reference for modern, framework-agnostic frontend work. Activate whenever the change touches HTML, CSS, design tokens, Tailwind configuration, accessibility, asset delivery, or vanilla JavaScript concerns that are not bound to a specific framework. Framework wiring (Astro, React, Vue, Svelte) belongs to its dedicated specialist — this skill stops at the platform boundary. ## When to activate - Writing or reviewing HTML markup, including semantic structure and forms. - Authoring CSS, design tokens, or Tailwind configuration. - Running an accessibility audit against WCAG 2.1 AA. - Diagnosing Core Web Vitals regressions (LCP, CLS, INP). - Optimizing fonts, images, or script loading. - Writing framework-agnostic JavaScript: observers, fetch, ES modules. ## HTML semantics Semantics are the cheapest accessibility win and the foundation every later layer depends on. Generic `<div>` soup forces you to bolt ARIA back on; semantic elements come with the correct role, focus behavior, and assistive-tech mapping for free. ### Document outline Each page has exactly one `<h1>` — typically the hero title.

How to install
mdr add crewrig/crewrig/frontend@sha256:27ee3714eee4f536The line at the top of this page pins the label git:20261018.1588e62, 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.
