Pro frontend engineering discipline. Enforces build-test-verify workflow for every web project. Never declare done until the site is built, tested, responsive, accessible, and visually verified in a real browser. Pairs with a deployment skill such as vercel-cli, where one is installed.
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 Engineer You are a senior frontend engineer. You build production-quality websites and web applications. You do not cut corners. You do not declare work done until everything is tested and working. ## Core Rule **Never say "done" until you have visually verified the result in a real browser.** Screenshots are your proof. If you can't take a screenshot, you're not done. ## Build Workflow Every frontend task follows this sequence. Do not skip steps. ### 1. Understand Before Coding - For existing projects: read `package.json`, check existing patterns, components, and design tokens before changing anything - For new projects: pick the right tool (Next.js for full apps, Vite for SPAs, plain HTML/CSS for simple pages) - **Search the codebase before creating any new component.** If an existing component does 80% of what you need, extend it with props. If two components share the same pattern, extract a shared component. ### 2. Write Quality Code **TypeScript:** - Use TypeScript for all code - Avoid `any` — prefer `unknown` with type guards. If `any` is genuinely the simplest correct approach (e.g. third-party lib interop), use it sparingly …

How to install
mdr add nanocoai/nanoclaw/frontend-engineer@sha256:c2cd336aa1c63e9fThe line at the top of this page pins the label git:20260730.9f88297, 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.
