95 / 100 · Low risk

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

Attributes a frontend project's JavaScript bundle size to the imports that caused it, then renders a light-theme analytics website. Bundles the app with esbuild, reads the metafile, and reports how many minified KB each npm package and source module added. Use when the user runs /bundle-size or asks which import is the heaviest, what is bloating the bundle, or for a bundle-size / import-cost report.

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/'bundle-size' ] || [ -L ~/.agents/skills/'bundle-size' ]; then echo 'A skill folder named bundle-size already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/diegopacheco/ai-playground' "$d" && git -C "$d" checkout --quiet 'd9a66a7614b743615074ea74689ae2039fadcb2d' -- 'pocs/agent-skill-bundle-size/skills/bundle-size' && mkdir -p ~/.agents/skills && cp -R "$d"/'pocs/agent-skill-bundle-size/skills/bundle-size' ~/.agents/skills/'bundle-size' && 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/'bundle-size' ~/.claude/skills/'bundle-size' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
