eas-observe – skill Agent & Tự động hóa cho agent AI

When to Use

• Use when this upstream workflow matches the user's stated goal.
• Use when the task requires the procedures documented in this skill.

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. 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.

Authorization and privacy

Confirm the existing EAS account/project, telemetry data policy and current plan before enabling collection, sending events or starting paid builds. Adding instrumentation can transmit routes, identifiers, error messages/stacks and request hosts. Do not collect secrets or unnecessary personal data; use synthetic test data, review route filtering before enabling integrations, and verify behavior on the installed SDK. Do not redirect telemetry to a custom endpoint without authorization. Preparing an integration does not authorize EAS project creation, dependency-wide repair, builds or feedback submission. Feedback commands download and execute a package and send data externally; use only when explicitly requested, with redacted content.

Which reference to read

The four reference files in ./references/ cover what 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+), mark the app interactive (global markInteractive() on SDK 55, the useObserve() hook or <ObserveInteractiveMarker /> on SDK 56+), optional per-route navigation metrics through the Expo Router / React Navigation integrations, user-defined events via Observe.logEvent (SDK 56+), error reporting, and runtime configuration (sampling, dispatch, environments, custom endpoint).
• Querying metrics from the terminal → [./references/queries.md]. The six eas observe:* commands — metrics-summary, metrics, routes, events, session, versions — with flags, metric aliases, table layouts, JSON shapes, and common workflows.
• Reading a dashboard or CLI output → [./references/metrics.md]. Target thresholds per metric, what the automatic TTI params mean (frameRate.*, device.*, network.*), and diagnostic patterns for telling slow-but-smooth startup apart from main-thread contention, hard blocks, or throttled devices.
• Shipping an Observe integration in a library → [./references/third-party.md]. For package authors only (SDK 57+): optional peer dependency, config declaration merging, Observe.registerIntegration(), and event naming.

Known gaps between the docs and the shipped code

Verified against eas-cli 21.8.0 and expo-observe 57.0.9. These are upstream snapshot observations, not a current verification; re-check with --help and the installed package before relying on them:

• All six CLI commands are on the [Querying with EAS CLI](https://docs.expo.dev/eas/observe/eas-cli/) page. Older doc builds list only four and omit observe:routes and observe:session.
• Navigation metric aliases are nav_cold_ttr, nav_warm_ttr, and nav_tti. There are no bare cold_ttr / warm_ttr aliases in the CLI.
• Sorting uses --sort <slowest|fastest|newest|oldest>. There is no --order flag.
• ObserveErrorBoundary, Observe.reportError, and configure({ errorHandlingEnabled }) are exported but undocumented. Observe still has no crash reporting; use Sentry or BugSnag for that.

Submitting Feedback

If you encounter errors, misleading or outdated information in this skill, report it so Expo can improve:

npx --yes submit-expo-feedback@latest --category skills --subject "eas-observe" "<actionable feedback>"

Only submit when you have something specific and actionable to report. Include as much relevant context as possible.

If an AI agent repeatedly failed or the user had to take over an Expo task, load the expo-skill-feedback skill and follow its eval-candidate flow instead of reusing the command above.

Examples

User: Apply this skill to my current task.
Assistant: Follow the workflow in this skill, cite limitations, and ask before risky steps.

Limitations

• Imported upstream skill; verify credentials, permissions, and safety boundaries before execution.
• Does not replace environment-specific validation, testing, or maintainer review.
