## Description

Use for anything related to EAS Observe - adding `expo-observe` to an Expo project (AppMetricsRoot/ObserveRoot HOC, markInteractive and ObserveInteractiveMarker, the useObserve hook, the Expo Router / React Navigation integrations for per-route metrics, the expo-image and Reanimated integrations, user-defined events via `Observe.logEvent`, error reporting via ObserveErrorBoundary and `Observe.reportError`, native crash reporting, source map upload for symbolicated stack traces, and runtime config such as sampleRate and dispatchInDebug), querying via the EAS CLI (`eas observe:metrics-summary`, `observe:metrics`, `observe:routes`, `observe:events`, `observe:session`, `observe:versions`, `observe:errors`, `observe:event`) or the Expo MCP `observe_*` tools, interpreting the resulting metrics (cold/warm launch, TTR, TTI, navigation cold/warm TTR, update download, and the TTI frameRate/device/network params for triaging slow startups), or shipping an Observe integration inside a third-party package.

# EAS Observe

> **EAS service - costs apply.** EAS Observe is an Expo Application Services product. The free EAS plan allows up to 10,000 monthly active users, with a limited set of features; higher usage requires a paid subscription. For details, see https://expo.dev/pricing#plan-features.

EAS Observe tracks startup, navigation, and custom-event performance from production Expo apps, and records JavaScript errors and native crashes. It needs a development or production build, the native library is not in Expo Go.

> **Source of truth:** https://docs.expo.dev/eas/observe/, always consult the canonical docs when API details matter, especially get-started, configuration, integrations, and the metrics reference. EAS Observe is evolving; this skill's references are written to stay accurate but may lag the docs.
