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.
Optimizing Lazy Layouts is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/optimizing-lazy-layouts/ and loads when your prompt matches the skill's trigger.
When to invoke it: 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.
The Optimizing Lazy Layouts Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 159,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
