Every team has one person who is designated and actually have to read a Perfetto trace - a queue of everyone else waiting on them. This session fixes both halves of that problem. First we walk the senior-engineer mental model live on a real trace: is the main thread running or waiting, which frame missed its 16.6 ms deadline and was it the app or SurfaceFlinger, where cold-start time actually goes, and where binder/IPC contention hides. Then we do something new , we encode that exact checklist into an AI agent that runs PerfettoSQL against a trace programmatically, ranks hotspots, and maps slice names back to the functions in your codebase. The result: you'll leave able to read a trace yourself, and able to hand that expertise to an agent so trace triage stops depending on one person. Whether you're chasing jank, slow cold starts, or ANRs, you'll have both the human method and a way to scale it across your team.
