By ariadoss/superskills (GitHub) · design · 12 stars · scanned at commit c7ec8d7

Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed. Biases towards retrieval from current documentation over pre-trained knowledge.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'web-perf' ] || [ -L ~/.agents/skills/'web-perf' ]; then echo 'A skill folder named web-perf 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 "$d" checkout --quiet 'c7ec8d78e5dc37484c2cfe90ab04de163d97dd41' -- 'skills/web-perf' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/web-perf' ~/.agents/skills/'web-perf' && 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/'web-perf' ~/.claude/skills/'web-perf' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
