Skill instructions
Analyze Performance Profiles Analyze .cpuprofile files (V8 sampling profiler) and DevTools trace files (Trace-.json, Chrome Trace Event Format) to find performance bottlenecks, compare code paths, and understand timing. When to Use - User provides a .cpuprofile or Trace-.json file and wants to understand performance - Investigating why one code path is slower than another - Finding what functions consume the most time - Comparing "before/after" or "old/new" implementations in a single profile - Investigating layout thrashing, long tasks, or rendering bottlenecks (trace files) - Analyzing VS Code user timing marks like code/didResolveTextFileEditorModel (trace files) - Understanding multi-process behavior (Browser, Renderer, GPU processes in trace files) Detecting File Type - .cpuprofile: Top-level JSON with nodes, samples, timeDeltas keys. Created by the VS Code profiler. - Trace-.json: Top-level JSON with traceEvents array (and optional metadata). Created by Chrome/Electron DevTools (
