analyzing-sql-traces
Extracts raw trace data from Perfetto traces, runs arbitrary SQL queries for custom follow-up analysis, and applies expert cognitive principles (Tiered Flow Analysis, Semantic Mismatch, Redundancy) to identify performance bottlenecks, structural redundancies, and tracer gaps. Use when you need to analyze a trace under a specific focus/entrypoint slice, identify uninstrumented 'black boxes', or execute arbitrary SQL queries on trace databases directly using SQLite/Perfetto SQL syntax, and generate a precise instrumentation breakdown plan or refactoring instructions for the Codebase Agent. Don't use for capture or compilation tasks.
