How does this skill help reduce cold starts?

It monitors your bundle size and flags heavy dependencies like Moment.js or Axios, suggesting lightweight native alternatives that keep worker initialization fast.

How does it handle CPU execution limits?

It identifies CPU-intensive loops or synchronous processing that might exceed the 50ms limit and suggests bounded operations or offloading patterns.

Does it support Cloudflare's specific caching mechanisms?

Absolutely. The skill detects missing caching opportunities for frequently accessed data and suggests implementation patterns for the Cloudflare Cache API.

Can it optimize slow storage operations?

Yes, it identifies sequential KV or D1 operations and provides code snippets to parallelize them using Promise.all(), significantly reducing round-trip latency.

Cloud Infrastructure

Optimizes Cloudflare Workers performance by reducing cold starts, minimizing bundle sizes, and implementing global edge caching patterns.

About

The Edge Performance Optimizer is a specialized Claude Code skill designed to audit and enhance Cloudflare Workers code for maximum efficiency. It automatically identifies performance bottlenecks such as heavy dependencies (e.g., Axios or Lodash), sequential storage operations, and missing caching headers, providing immediate remediation strategies to reduce global latency and minimize CPU time. Whether you are troubleshooting high cold start times or optimizing KV/R2/D1 access patterns, this skill ensures your edge applications meet production-grade performance standards.
