Framework-agnostic frontend architecture playbook. Workflows for picking rendering (SSG / SSR / SPA / ISR), setting bundle budgets, choosing state management (local / server / global), Core Web Vitals tracking + INP debugging, accessibility floor enforcement, testing pyramid, and supply-chain security. Use when designing a new frontend project, auditing an existing one, picking between React / Vue / Svelte / Astro, debugging perf, or wiring CI gates for a SPA / SSG / SSR app.
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 Engineering Playbook Framework-agnostic. React, Vue, Svelte, Solid, Astro, Next, Nuxt, Gatsby, Hugo, SvelteKit, Remix - the architecture decisions and CI discipline are the same; the framework is the implementation. **Companion rule:** `260-frontend.mdc`. The rule is what auto-loads when an agent edits `.tsx` / `.vue` / `vite.config.*` / etc.; this skill is the depth. --- ## When to invoke - Designing a new frontend project (greenfield) - Auditing an existing frontend project (perf, a11y, security) - Choosing between SPA / SSG / SSR / ISR / hybrid rendering - Setting up Core Web Vitals tracking (lab + RUM) - Picking state management (and unbreaking a Redux/Zustand-stuffed-with-server-data mess) - Hitting an INP / LCP / CLS regression - Wiring CI gates: bundle budget, axe-core, Lighthouse Do not use for: - Framework-specific syntax help (defer to framework docs) - CSS architecture (BEM vs Tailwind vs CSS-in-JS - taste + team conventions) - Design system decisions (out of scope; that is a design org problem) --- ## Five Golden Rules …

How to install
mdr add d-padmanabhan/agent-engineering-handbook/frontend-engineering@sha256:81842e7f02ef7214The line at the top of this page pins the label git:20260906.0766fec, 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.
