# Optimize
This is the Impeccable optimize mode alias.
Use the installed `impeccable` skill as the design context first, then focus only
on measurable frontend performance.
## Workflow
1. Measure the current state before changing code: Core Web Vitals, load time,
bundle size, network waterfall, runtime frame rate, memory, and CPU.
2. Identify the bottleneck category: images, JavaScript, CSS, fonts, rendering,
animation, network, or unnecessary work.
3. Apply the smallest change that can improve the measured bottleneck.
4. Re-measure after the change and report whether the target metric improved.
Avoid premature optimization. Optimize the path users actually feel.
