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

Guides debugging and optimizing Largest Contentful Paint (LCP) using Chrome DevTools MCP tools. Use this skill whenever the user asks about LCP performance, slow page loads, Core Web Vitals optimization, or wants to understand why their page's main content takes too long to appear. Also use when the user mentions "largest contentful paint", "page load speed", "CWV", or wants to improve how fast their hero image or main content renders.

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/'debug-optimize-lcp' ] || [ -L ~/.agents/skills/'debug-optimize-lcp' ]; then echo 'A skill folder named debug-optimize-lcp already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/zenobi-us/dotfiles' "$d" && git -C "$d" checkout --quiet 'dee00b4124b8f4b442b8774449018308a57e32b1' -- 'mise/conf.d/devtools-agent/bundles/developer/skills/browsers/debug-optimize-lcp' && mkdir -p ~/.agents/skills && cp -R "$d"/'mise/conf.d/devtools-agent/bundles/developer/skills/browsers/debug-optimize-lcp' ~/.agents/skills/'debug-optimize-lcp' && 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/'debug-optimize-lcp' ~/.claude/skills/'debug-optimize-lcp' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
