65 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

Performance profiling — measures code execution time, DB call time, and identifies bottlenecks at both the application and database layer. Use when asked to "profile performance", "measure execution time", "find bottlenecks", "check response times", or "why is this slow".

Works with any agent that supports SKILL.md skills.

Safer alternatives

Low-risk skills in the same category (coding) that look related. Check that one does what you need.

Install

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

if [ -e ~/.agents/skills/'perf-profile' ] || [ -L ~/.agents/skills/'perf-profile' ]; then echo 'A skill folder named perf-profile already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ariadoss/superskills' "$d" && git -C "$d" checkout --quiet 'c7ec8d78e5dc37484c2cfe90ab04de163d97dd41' -- 'skills/perf-profile' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/perf-profile' ~/.agents/skills/'perf-profile' && 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/'perf-profile' ~/.claude/skills/'perf-profile' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
