By hiroqt/PixelCrew (GitHub) · design · 11 stars · scanned at commit bb64114

Comprehensive guide for full-stack performance engineering across frontend Core Web Vitals (LCP, INP, CLS, TTFB, streaming SSR, priority hints, main thread yielding), backend runtime profiling, multi-tier caching (L1 in-memory, L2 Redis, L3 CDN Edge, XFetch stampede prevention), database query tuning, network transport, automated k6 load & stress testing, and SLA/SLO/SLI error budgets.

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/'performance-engineering' ] || [ -L ~/.agents/skills/'performance-engineering' ]; then echo 'A skill folder named performance-engineering already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hiroqt/PixelCrew' "$d" && git -C "$d" checkout --quiet 'bb641146b68787e27a6fbe3881044aa67c8d5390' -- '.agents/skills/performance-engineering' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/performance-engineering' ~/.agents/skills/'performance-engineering' && 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/'performance-engineering' ~/.claude/skills/'performance-engineering' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
