Instruments Profiling

Native macOS/iOS app performance profiling via xctrace/Time Profiler and CLI-only analysis of Instruments traces. Use when asked to profile, attach, record, or analyze Instruments .trace files, find hotspots, or optimize native app performance without opening Instruments UI.

Use this skill for any operation with the Indices CLI — authentication, tasks, runs, and secrets.

Analyze code performance to identify bottlenecks, detect redundant computations and blocking operations, and provide optimization recommendations.

Analyze Instagram profiles and posts with detailed engagement metrics, view tracking, follower ratios, and Reels-focused analytics with JSON/CSV export.

Profile and optimize application performance. Use when diagnosing slow code, measuring CPU/memory usage, generating flame graphs, benchmarking functions, load testing APIs, finding memory leaks, or optimizing database queries.

Profile construction data to understand characteristics, distributions, quality metrics, and patterns. Essential for data quality assessment and ETL planning.
