Rebuilds an app screen by screen from the recon map: app shell first, then the core flow as a vertical slice, then every screen with all its states, ticking off the feature matrix as it goes. Writes every line fresh, never the original's code, assets or copy. Use when the user says "build the clone", "build screen S07", "start building", "rebuild this screen", "implement the booking page", or after /replica-design.
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
# replica-build Reads `replica/recon.md`, `replica/architecture.md`, `replica/design/`. Updates `replica/features.csv` (the `clone` column) and keeps `replica/build-log.md`. ## The rules - **Clean room.** Every line of code is written here, from the recon map and the specs. Never paste the original's HTML, CSS, JavaScript, SVGs or images, never load anything from its domain or CDN, never "view source and adapt". - **Your words.** Write every label, button, empty state and email fresh. Matching what a button does is parity. Matching its sentence is copying. - **Tokens only.** No raw hex or pixel values in components. If a value is missing, add it to the tokens. ## Step 1: the shell Routing for every screen in the inventory (stub pages are fine), the layout (nav, header, sidebar), tokens wired in, the primitives from replica-design, and seed data so screens have something real to show. Commit. ## Step 2: the vertical slice The core loop from the recon map, end to end, before anything else. For a booking app: create an event type, open the public page, book a slot, see it on the dashboard. Ugly is fine. Working is the point. If replica-backend has …

How to install
mdr add realtahailyas/reverse-engineer-app-skills/replica-build@sha256:e50e00ec3ea1cb23The line at the top of this page pins the label git:20261021.9d48208, 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.
