Fine to try. Some of what it can do is expected: a media skill usually calls an AI service over the internet.

Guide performance profiling for Apple platform apps with Instruments, Xcode diagnostics, and MetricKit. Use when investigating app hangs, stutters, high CPU, memory leaks, memory growth, OOM crashes, slow launch, battery drain, thermal issues, App Store performance readiness, or when adding os_signpost and measurement hooks.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'performance-profiling' ] || [ -L ~/.agents/skills/'performance-profiling' ]; then echo 'A skill folder named performance-profiling already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/nirholas/three.ws' "$d" && git -C "$d" checkout --quiet '89050b3166a89e4c21e78c7bc936c142784a6327' -- 'third_party/designcode-agent-skills/agent-skills/codex/performance-profiling' && mkdir -p ~/.agents/skills && cp -R "$d"/'third_party/designcode-agent-skills/agent-skills/codex/performance-profiling' ~/.agents/skills/'performance-profiling' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'performance-profiling' ~/.claude/skills/'performance-profiling' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
