Excellent skill for CLI-only native app performance profiling. The description clearly conveys when to use it (xctrace/Instruments without UI). SKILL.md provides a complete workflow: record → extract → symbolicate → analyze hotspots, with concrete command examples and gotchas (ASLR, binary path matching). Task knowledge is strong with referenced scripts handling each step. Structure is clean with quick-start commands and workflow notes. High novelty: profiling native apps and parsing Instruments traces via CLI would be token-intensive and error-prone for a raw CLI agent. Minor improvement: could explicitly mention simulator vs device profiling constraints, but overall very useful and well-documented.
