Summary
When your React Native app stutters or leaks on the native side, this skill grabs xctrace profiles on iOS or Perfetto traces on Android and breaks them down into CPU hotspots, UI hangs, and memory leaks. It auto-detects your running app, records while you interact, then parses the trace into a severity-ranked report you can drill into with stack queries. The workflow is end-to-end: start, stop, analyze, then query specific hang stacks or leak callchains. One thing to watch: iOS simulator leaks often come back unattributed because xctrace attaches without malloc stack logging, so you'll need to cold-launch with that flag enabled if you want real allocation backtraces.
