Use this skill to fix scroll jank, lost item state, and broken animateItem() animations in LazyColumn, LazyRow, LazyVerticalGrid, and LazyHorizontalGrid. Covers stable item keys, contentType for mixed-type feeds, Modifier.animateItem() requirements, hoisting modifier chains and painters out of the items lambda, and validating item composable stability. Use when the developer mentions LazyColumn jank, dropped frames while scrolling, items losing scroll state on insert/remove/reorder, mixed feeds of cards/headers/ads feeling sluggish, animateItem() not animating, RecyclerView view-type analog, key parameter, or contentType parameter. The prefetch-window tuning lives in a sibling skill.

From the source SKILL.md

Lazy layouts compose only what's visible, but two things still cost: re-composition of items that should have been reused (missing key), and per-item allocation that compounds with scroll velocity (missing contentType, modifier chains created inside items { }). Both have a one-line fix. This skill teaches Claude how to apply that fix correctly and to validate that item composables are themselves skippable. Prefetch tuning is a separate concern — see ../configuring-lazy-prefetch/SKILL.md.
