Mechanism
Breaks down how the skill works and what it produces, so you can quickly judge whether it fits your scenario and value.
When a user needs to add EAS Observe to an Expo project, query production metrics via EAS CLI, or interpret Observe dashboards/CLI output for performance triage.
eas observe:* subcommands with flags for summaries, routes, events, versions.A production-instrumented Expo app sending metrics, terminal queries returning structured data, and clear diagnosis of slow startup causes.
Use Cases
A team ships an Expo app to production and wants startup monitoring. They use this skill to add expo-observe via AppMetricsRoot and markInteractive, then run `eas observe:metrics-summary` to watch cold/warm launch and TTI. This reveals slow startups early and helps prioritize fixes before users churn.
A developer sees rising crash-free sessions drop after an OTA update. Using this skill's queries.md, they run `eas observe:versions` and `eas observe:routes` to compare update channels and route-level TTR. The frameRate params in metrics.md show main-thread contention, guiding a targeted fix.
