Native App Performance

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.

This skill appears coherent and focused on local macOS/iOS profiling. Before installing or running it: (1) confirm you're on macOS with Xcode command-line tools (xcrun/xctrace, atos, otool, vmmap) available; (2) review the included scripts (they invoke subprocesses) and only supply trace files, binary paths, or PIDs you trust; (3) be aware the scripts execute local developer tools and read files but do not perform network calls or request credentials; (4) run in a controlled environment if you are concerned about running arbitrary scripts — but functionally these scripts perform exactly the profiling/symbolication tasks described.

Type: OpenClaw Skill Name: native-app-performance Version: 1.0.0 This skill bundle is designed for CLI-only performance profiling of macOS/iOS applications using standard Apple developer tools. All scripts (`record_time_profiler.sh`, `extract_time_samples.py`, `top_hotspots.py`) leverage `xcrun xctrace`, `vmmap`, `otool`, and `atos` for their intended purposes (recording traces, extracting data, symbolication, and hotspot analysis). The `SKILL.md` provides clear, focused instructions without any prompt injection attempts or directives for malicious actions. There is no evidence of data exfiltration, unauthorized execution, persistence, or obfuscation. The use of shell commands and file access is strictly aligned with the stated performance profiling objective.
