This orchestrates performance optimization across your entire stack, from profiling and database tuning to frontend bundles and CDN config. It spins up specialized subagents for each layer (performance engineers, database optimizers, frontend devs) and walks through a methodical four-phase process: establish baselines with flame graphs and Core Web Vitals, optimize backend and databases, handle frontend splitting and edge caching, then validate with load tests. Best for when you're tackling system-wide performance issues rather than isolated fixes. The workflow assumes you have access to profiling data and APM tools, so it won't help much if you're flying blind on metrics.
