npx skillmds add expo/expo-observe

Or Copy and Paste in Your Agent chat

Please install the Agent Skill "expo/expo-observe" for me from skillmd.com. A SkillMD skill is a SKILL.md file — plain markdown — that you save into my skills directory. Use whichever fetch route fits your setup: (1) if you have a terminal, run npx -y skillmds add expo/expo-observe; (2) otherwise fetch https://api.skillmd.com/api/skills/expo/expo-observe/raw (served as text/markdown) and save it as expo-observe/SKILL.md in your skills directory; (3) if the SkillMD MCP tools are connected, call skillmd_download with slug "expo/expo-observe" and save the returned files under expo-observe/. Show me the SKILL.md before saving if you'd like me to review it. If your skills directory is read-only (e.g. the Claude desktop app), save the files to a working folder instead and tell me — I'll add them through my app's skills settings.

SKILL.md

EAS Observe

EAS Observe tracks startup, navigation, and custom-event performance from production Expo apps.

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.

Which reference to read

The three reference files in ./references/ cover the three things people typically need this skill for:

Adding EAS Observe to a project → ./references/setup.md. Install, wrap the root layout (AppMetricsRoot on SDK 55, ObserveRoot on SDK 56+), call markInteractive() (global on SDK 55, via the useObserve() hook on SDK 56+), optional per-route navigation metrics through the Expo Router / React Navigation integrations, and user-defined events via Observe.logEvent (SDK 56+).
Querying metrics from the terminal → ./references/queries.md. The five eas observe:* commands — metrics-summary, metrics, routes, events, versions — with flags, table layouts, JSON shapes, and common workflows.
Reading a dashboard or CLI output → ./references/metrics.md. Target thresholds per metric, what the TTI frameRate.* params mean, and diagnostic patterns for telling slow-but-smooth startup apart from main-thread contention or hard blocks.

# EAS Observe

EAS Observe tracks startup, navigation, and custom-event performance from production Expo apps.

> **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.

## Which reference to read

The three reference files in `./references/` cover the three things people typically need this skill for:

- **Adding EAS Observe to a project** → [`./references/setup.md`](./references/setup.md). Install, wrap the root layout (`AppMetricsRoot` on SDK 55, `ObserveRoot` on SDK 56+), call `markInteractive()` (global on SDK 55, via the `useObserve()` hook on SDK 56+), optional per-route navigation metrics through the Expo Router / React Navigation integrations, and user-defined events via `Observe.logEvent` (SDK 56+).
- **Querying metrics from the terminal** → [`./references/queries.md`](./references/queries.md). The five `eas observe:*` commands — `metrics-summary`, `metrics`, `routes`, `events`, `versions` — with flags, table layouts, JSON shapes, and common workflows.
- **Reading a dashboard or CLI output** → [`./references/metrics.md`](./references/metrics.md). Target thresholds per metric, what the TTI `frameRate.*` params mean, and diagnostic patterns for telling slow-but-smooth startup apart from main-thread contention or hard blocks.
