Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Performance-trace Nub package-manager installs using the existing phase timings, structured diagnostics, and sampling-profiler workflow. Use when an install or package-manager operation is unexpectedly slow and the bottleneck needs to be localized before changing code.

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/'pm-perf-tracing' ] || [ -L ~/.agents/skills/'pm-perf-tracing' ]; then echo 'A skill folder named pm-perf-tracing already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/nubjs/nub' "$d" && git -C "$d" checkout --quiet '9b734566fd36ceed8379f67a92291bc68af60801' -- '.claude/skills/pm-perf-tracing' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/pm-perf-tracing' ~/.agents/skills/'pm-perf-tracing' && 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/'pm-perf-tracing' ~/.claude/skills/'pm-perf-tracing' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
