RN Project Snapshot — Read-Only Environment & Config Overview

Overview

Surfaces a React Native project's high-level environment and config state by reading stable files (and, optionally, the project's own env command), then routes you to the focused audits for deeper work. This is a read-only reader: it inspects and reports, never mutates, and introduces no new CLI. It stays shallow on purpose — dependency readiness and asset analysis live in their dedicated skills, not here.

When to Use

• "what's the state of this RN project?", "is the New Architecture on here?", "bare or Expo?"
• First look at an unfamiliar RN repo, before deciding what to audit or upgrade
• Quick pre-upgrade orientation

Prerequisites

• A React Native or Expo project
• Node for the optional npx enrichment; offline still works from file reads alone (with a stated caveat)
• Read-only — no clean git tree required

Quick Steps (all read-only)

1 — Detect project type and versions

cat package.json                 # react-native / expo / react versions, scripts
ls package-lock.json yarn.lock pnpm-lock.yaml bun.lockb 2>/dev/null   # package manager

2 — Read New Architecture + Hermes flags across platforms

cat android/gradle.properties 2>/dev/null    # newArchEnabled, hermesEnabled
cat app.json app.config.* 2>/dev/null        # Expo newArchEnabled
ls ios/Podfile ios/*.xcworkspace 2>/dev/null # iOS native shell present?

3 — Optional enrichment (network)

npx react-native info        # bare projects — environment report
npx expo config --json       # Expo projects — resolved config

4 — Present the snapshot and route

Show the values as a compact snapshot. Where a flag differs across platforms, surface the difference — do not decide readiness here. Then route to the right audit (see Routing).

How It Works

package.json + lockfiles ─┐
android/gradle.properties ─┤   read stable files
app.json / app.config.*  ─┤   (+ optional npx env command)   ──►  compact snapshot
ios/Podfile              ─┘                                         (versions · flags · config presence)
                                                                          │
                                                                          ▼  interpret + route (no readiness verdict)
