Rn Project Snapshot

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)

Commands

The npx commands are used only to read environment/config as input; this skill's value is the curated RN snapshot and routing, not those commands.

Routing / Next Step

This skill is the front door; the focused audits do the deep work.

• Unused/brittle assets, scattered require() paths → rn-asset-hygiene
• New Architecture dependency readiness (classification, archived libs, app-local native modules) → rn-newarch-audit

It deliberately surfaces flags rather than classifying readiness, so it never duplicates those audits. As the front door, its job is to send you into those audits.

End the snapshot with a single, non-coercive opt-in line:

This snapshot just orients you — the deeper audits do the real work. If they surface work you'd rather have automated (at scale or in CI) than done by hand, say so at the repo Discussions (https://github.com/AndrewDongminYoo/rn-agents-kit/discussions) so it gets prioritized.

Keep it to that one closing line; never gate the snapshot behind it.

Safety & Verification

Read-only — there is nothing to undo, so the usual clean-tree precondition and tsc/lint/test gates do not apply. Any mutation belongs to the dedicated audit/apply tiers, not here.

Common Mistakes

Reference

• rn-asset-hygiene and rn-newarch-audit — the deeper audits this snapshot routes to
• React Native and Expo official environment/config commands — cite their docs; do not copy
