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

JavaScript bundle size auditor and budget enforcer. Parses webpack stats JSON, Vite bundle report, Rollup output, or Next.js build output to identify largest chunks, flag chunks that exceed configurable size budgets, detect duplicate dependencies across chunks, find treeshaking failures (packages that should be side-effect-free but aren't), and generate CI fail-gate commands. Outputs a GitHub PR annotation-ready summary with per-chunk size, gzip estimate, and actionable optimization suggestions…

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/'phy-bundle-size-audit' ] || [ -L ~/.agents/skills/'phy-bundle-size-audit' ]; then echo 'A skill folder named phy-bundle-size-audit already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/LeoYeAI/agent-master-skills' "$d" && git -C "$d" checkout --quiet '8f88f9a0dd5a1075d4f0c7626f9d960844d57575' -- 'skills/phy-bundle-size-audit' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/phy-bundle-size-audit' ~/.agents/skills/'phy-bundle-size-audit' && 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/'phy-bundle-size-audit' ~/.claude/skills/'phy-bundle-size-audit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
