Summary

Callstack's patterns for building React Native apps in GitHub Actions and pulling down the artifacts afterward. You get composite actions for iOS simulator and Android emulator builds, plus a workflow that ties them together and spits out stable artifact IDs you can grab with gh CLI or the REST API. Honestly most useful if you're tired of "works on my machine" and want teammates to test PR builds without cloning and compiling locally. The artifact upload uses actions/upload-artifact@v4 and the docs show you exactly how to script downloads, which saves you from reinventing that wheel every time.

expo-observe

expo/skills

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).

figma avatar
figma-use

figma/mcp-server-guide

**MANDATORY prerequisite** — you MUST invoke this skill BEFORE every `use_figma` tool call. NEVER call `use_figma` directly without loading this skill first. Skipping it causes common, hard-to-debug failures. Trigger whenever the user wants to perform a write action or a unique read action that requires JavaScript execution in the Figma file context — e.g. create/edit/delete nodes, set up variables or tokens, build components and variants, modify auto-layout or fills, bind variables to properties, or inspect file structure programmatically.
