Plans the stack, database schema and API for an app clone, from the recon map replica-recon wrote. Picks boring, managed tech, turns the inferred data model into real SQL with indexes and access rules, lists every route by flow, and orders the build as a thin vertical slice first. Use when the user says "plan the clone", "what stack should I use", "design the database", "write the schema", "plan the API", "architecture for my version of X", or after /replica-recon finishes.
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-architect Reads `replica/recon.md` and `replica/features.csv`. Writes `replica/architecture.md` (template: architecture.md in this folder). If there is no recon map, stop and run `/replica-recon` first. Planning a clone from memory of what an app does is how you miss half of it. ## Step 1: the stack Use what the user already knows if they have a stack. Otherwise the default, because every part is managed, documented and cheap at zero users: | layer | default | swap for | | --- | --- | --- | | web app | Next.js (App Router) + TypeScript | Remix, SvelteKit, Rails | | styling | Tailwind, tokens from replica-design | CSS modules | | mobile | Expo (React Native) | SwiftUI, Kotlin | | database | Postgres on Supabase or Neon | PlanetScale, SQLite (Turso) | | ORM | Drizzle or Prisma | raw SQL | | auth | Supabase Auth or Auth.js | Clerk | | payments | Stripe Checkout + Billing | Lemon Squeezy, Paddle | | email | Resend or Postmark | SES | | jobs | Vercel Cron, Inngest or Trigger.dev | a worker on Fly | | files | Supabase Storage or Cloudflare R2 | S3 | | hosting | Vercel | Netlify, Fly, Render | Write each choice with one line of why.

How to install
mdr add realtahailyas/reverse-engineer-app-skills/replica-architect@sha256:411c429c9b3e6858The 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.
