brownfield-onboarding skillA
brownfield-onboarding is agent-read markdown (skill) from vmobifystudio/app-dev-team: Use when pointing the team at an EXISTING, already-built app instead of a blank project — detects the stack, reverse-engineers the as-built architecture, and classifies remediation work as safe-to-auto-fix vs risky-needs-approval. Triggered by /app-onboard, /app-audit, and by /app-run when it detects a non-empty app directory..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Brownfield onboarding Greenfield commands generate vision → PRD → architecture → code. For an app that already exists, you go the other way: **read the code, snapshot what's there, grade it against the House KB, and plan the gap.** This skill is the procedure for the "read and understand" half. ## When to use - `/app-onboard` (adopt an existing codebase) and `/app-audit` (grade it) both start here. - `/app-run` invokes this when the target directory already contains an app (see Detection). ## Step 1 — Detect the app Scan the target directory (not deeper than ~3 levels) to establish ground truth before any agent reasons about it: - **iOS:** `*.xcodeproj` / `*.xcworkspace` / `Package.swift`; read `project.yml` (XcodeGen), `*.xcconfig`, `Info.plist`, `Package.resolved`. Note Swift version, min iOS target, SwiftUI vs UIKit. - **Android:** `settings.gradle*`, `app/build.gradle(.kts)`, `gradle/libs.versions.toml`. Note Kotlin/AGP, `compileSdk`/`minSdk`/`targetSdk`, Compose vs XML, the module list. - **Both / signals:** existing `CLAUDE.md`, `README`, `docs/`, CI under `.github/workflows`, …

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
