Builds UI that holds up at every width, in both themes, with real data, and for someone on a keyboard. Use when a page or a component is being added or restyled, when a layout breaks on a narrow screen or in dark mode, or when a view has no empty, loading or error state. Auto-triggers on: "build a component", "add a page", "style this", "make it responsive", "dark mode", "the layout breaks".
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 UI is where "it works on my machine" hides best: it renders on your screen, in your theme, with your data, at your width. Correctness here means it holds at every width, in both themes, with no data and with too much, and for someone not using a mouse. Depth lives in `reference.md` (tokens, layout, state) and `a11y.md` (the gate). Read them when you reach that step, not before. ## 1. Look before you add - `devil facts` for the framework, the test runner and the lint setup. Do not introduce a second styling approach, state library or component kit — that is a fork in the codebase (`rules/minimalism-ladder.md` rung 4). - Find the nearest existing component and mirror its structure, naming and file layout. The codebase's convention beats your preference. - `devil dupes` — a third copy of the same button is an extraction (`rules/library-first.md`). ## 2. Draw the boundaries first - **State lives at the lowest common owner** of everything that reads it. Lifting everything to the top is how a page re-renders on every keystroke. - **Server state is not UI state.** Cache, loading and error belong to a data layer, not to twelve `useState` calls. …

How to install
mdr add univers42/claude-deal-with-the-devil/frontend@sha256:79e2f7518bf89c0bThe line at the top of this page pins the label git:20260930.00e2d41, 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.
