Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to "review since X".
Run split-context adversarial review on code changes — Bugbot, security review, repo contract checks, and react-doctor (changed-scope scan), then apply fixes from serialized findings. Use after implementing a feature or fix, before merge, when finishing a ticket, or when the user asks for adversarial review.
EAS service (paid). Deploy Expo apps to the app stores with EAS - build and submit to the iOS App Store, Google Play Store, and TestFlight, configure eas.json build and submit profiles, manage app versions and build numbers, and publish App Store metadata and ASO. Use whenever the user wants to deploy, release, or ship an app to production or the app stores, is preparing a production build, running eas build or eas submit, shipping to TestFlight, bumping version or build numbers, or setting up store listing metadata. For deploying an Expo website or API routes, use the eas-hosting skill.
EAS service (paid). Deploy Expo websites and Expo Router API routes to EAS Hosting - export the web bundle, run eas deploy for production and PR preview URLs, manage environment secrets and custom domains, and work within the Cloudflare Workers runtime. Also covers authoring API routes (+api.ts handlers, HTTP methods, request handling, CORS). Use when deploying an Expo web app or API routes, setting up EAS Hosting, or configuring hosting environments and domains. Not for native builds or store releases - use the eas-app-stores skill for those.
EAS service (paid). Use for anything related to EAS Observe - adding `expo-observe` to an Expo project (AppMetricsRoot/ObserveRoot HOC, markInteractive, the useObserve hook, the Expo Router / React Navigation integrations for per-route metrics, and user-defined events via `Observe.logEvent`), querying via the EAS CLI (`eas observe:metrics-summary`, `observe:metrics`, `observe:routes`, `observe:events`, `observe:versions`), or interpreting the resulting metrics (cold/warm launch, TTR, TTI, navigation cold/warm TTR, update download, and the TTI frameRate params for triaging slow startups).
EAS service (paid). Run and control a user's app on a remote iOS/Android simulator hosted on EAS cloud. Read before running any `eas simulator:*` commands - it has the current syntax for this experimental API. Use whenever the user needs a simulator they can't run locally - 'run my app on a cloud simulator', 'use eas simulator to run/install/screenshot my app', 'I'm on Linux/Cursor and need an iOS device', 'no sim on this box / headless CI', 'let an agent click through my app and screenshot it', 'test my dev build on a remote sim with live reload', 'stream a sim to my browser' - even when they don't say 'EAS Simulator' or 'cloud'. On a host WITHOUT a local simulator (Linux, CI, cloud sandbox) it's the default; on macOS, do NOT auto-trigger for a plain 'run on the simulator' - use it only for a cloud/remote/shareable sim, an iOS version they lack, or an agent-driven session. NOT for local sims (expo run:ios, Xcode, Android Studio), EAS Build/Update, web preview, or physical devices.

Router for React Native internals. Private setup before using this skill:
agent-device --version
Require agent-device >= 0.14.0; older CLIs lack these help topics. If older, run npm install -g agent-device@latest, recheck, then continue. If you cannot upgrade, stop and tell the user. Do not include version/upgrade commands in final plans.
Read current CLI guidance:
agent-device help react-devtools
Use agent-device react-devtools ... for component tree, props, state, hooks, render ownership, performance profiling, slow components, or rerenders. It dynamically runs pinned agent-react-devtools@0.4.0. Use normal agent-device commands for visible UI, refs, screenshots, logs, network, or device-level perf.
Core loop:
agent-device react-devtools status
agent-device react-devtools wait --connected
agent-device react-devtools get tree --depth 3
agent-device react-devtools profile start
# perform the interaction with normal agent-device commands
agent-device react-devtools profile stop
agent-device react-devtools profile slow --limit 5
agent-device react-devtools profile rerenders --limit 5
Remote iOS bridge order:
agent-device open <bundle-id> --platform ios --relaunch
agent-device react-devtools start
agent-device open <bundle-id> --platform ios --relaunch
agent-device react-devtools wait --connected
Rules:
Keep reads bounded with --depth/find, treat @c refs as reload-local, profile only the investigated interaction, and run the same command in remote Android sessions; the CLI manages the needed local service tunnel. For remote iOS, relaunch after react-devtools start because React Native opens the legacy DevTools websocket during JavaScript startup.
