Making a web frontend fast: Core Web Vitals and budgets, what loads first, images and fonts, JavaScript weight and code splitting, rendering strategy and hydration, INP and long tasks, layout shift, caching and a CDN, long lists, and measuring in the lab and the field. Read before building a page that must load fast, and when one is slow.

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/'frontend-performance' ] || [ -L ~/.agents/skills/'frontend-performance' ]; then echo 'A skill folder named frontend-performance already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/enowdev/enowxcli' "$d" && git -C "$d" checkout --quiet '38293fe1b096e6bf3646c7344c38786ed688f464' -- 'crates/enowx-core/skills/frontend-performance' && mkdir -p ~/.agents/skills && cp -R "$d"/'crates/enowx-core/skills/frontend-performance' ~/.agents/skills/'frontend-performance' && 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/'frontend-performance' ~/.claude/skills/'frontend-performance' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
