Instruments/xctrace profiling: macOS/iOS traces, binaries, args, exports.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Instruments Profiling (macOS/iOS) Use this skill when the user wants performance profiling or stack analysis for native apps. Focus: Time Profiler, `xctrace` CLI, and picking the correct binary/app instance. ## Quick Start (CLI) - List templates: `xcrun xctrace list templates` - Record Time Profiler (launch): - `xcrun xctrace record --template 'Time Profiler' --time-limit 60s --output /tmp/App.trace --launch -- /path/To/App.app` - Record Time Profiler (attach): - Launch app yourself, get PID, then: - `xcrun xctrace record --template 'Time Profiler' --time-limit 60s --output /tmp/App.trace --attach <pid>` - Open trace in Instruments: - `open -a Instruments /tmp/App.trace` Note: `xcrun xctrace --help` is not a valid subcommand. Use `xcrun xctrace help record`. ## Picking the Correct Binary (Critical) **Gotcha: Instruments may profile the wrong app** (e.g., one in `/Applications`) if LaunchServices resolves a different bundle. Use these rules: - Prefer direct binary path for deterministic launch: - `xcrun xctrace record ... --launch -- /path/App.app/Contents/MacOS/App` - If launching `.app`, ensure it’s the intended bundle: - `open -n /path/App.app` …

How to install
mdr add steipete/agent-scripts/instruments-profiling@sha256:7b6bdce32c898cdcThe line at the top of this page pins the label git:20260523.0a2d76c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
