Excerpt

Happier Profile and Optimize

Use this skill for any work whose success is a measured cost, not a behavior: slow open/foreground/navigation, jank, hangs, startup, memory, render churn, a query that got slow, or verifying somebody's speedup claim. It is the investigation method — reach for it once a cost exists.

This is the opening of the README. Read the full README on GitHub.
