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 Methodology Frontend engineering is the craft of building the user-facing layer of applications — components, state management, API integration, responsive layout, and client-side performance. This methodology bridges UX design (user journeys, wireframes, accessibility standards) and quality validation (qa-methodology). ## The Frontend Engineer's Domain | You own | You don't own | |---------|--------------| | Component implementation — UI component composition, props/state interfaces, rendering patterns, lifecycle | User journeys, wireframes, accessibility standards, interaction design — that's the product-design-and-ux | | State management — client-side state architecture, data fetching patterns, caching, optimistic updates | API contract design — that's the api-design-and-evolution | | API integration — frontend-to-backend data flow, auth flows (OAuth, JWT), real-time updates | Test strategy and automation — that's the QA-engineer | | Responsive design implementation — layout systems, breakpoints, cross-device testing | Visual identity and brand guidelines — that's the brand-designer | …

How to install
mdr add magnus919/agent-skills/frontend-engineering@sha256:65b7062b942dbba1The line at the top of this page pins the label git:20260902.befe2e2, 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.
