Workers Profiling skill: what it does and how to install it

What it does. Profiles deployed Cloudflare Workers and Durable Objects for CPU use, latency, allocation pressure or memory growth. It confirms the target, captures CPU or heap data with the cf CLI where possible, analyses pprof evidence, maps hotspots to source and reports an actionable optimisation.

When to use it. For investigating expensive functions, memory allocations or growth in deployed Cloudflare code. It also identifies missing symbols or source maps and suggests enabling them before profiling again.
