**Make your AI coding tool understand Compose recomposition performance.**

AI tools don't understand recomposition budgets. They'll tell you "use `remember`" or "add `@Stable`" without knowing whether the problem is a forced recomposition from a parent, an unstable lambda, or a screen-level state read. This skill gives them the domain knowledge to diagnose and fix correctly.

What Changes

Without Skill	With Skill
"Use `remember` to fix recomposition"	"Your `HomeScreen` recomposes 8/s (budget: 3/s SCREEN). The `$changed` mask shows `scrollOffset` is DIFFERENT every frame. Hoist it to `ContentSection`."
"Add `@Stable` to your data class"	"Skip rate is 12% with `paramTypes: unstable,lambda`. The `UserCard` data class needs `@Immutable` (all vals), and the `onClick` lambda should be `remember`-wrapped."
"That looks fine"	"Forced count is 45 vs param-driven 3 — the parent `ChatList` is the real violator. Fix the parent first, children will stop cascading."
