React Performance And Delivery Optimization is a community-contributed Claude Code skill in the frontend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/react-performance-and-delivery-optimization/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when defining, reviewing, or hardening the performance and delivery posture of a React app against Web Vitals budgets after the other react archetypes exist and performance architecture has set per-route budgets. Produces per-route performance budgets, code-splitting and lazy-loading topology, image and font posture, third-party-script audit, Web Vitals instrumentation (LCP/CLS/INP/TTFB), Lighthouse and bundle-analyzer CI gates, and CDN/edge cache-control posture.
The React Performance And Delivery Optimization Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 161,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
