Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cpu-cache-layout-optimization

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent measures cache misses with perf counters, spots false sharing and poor locality, then proposes an AoS or SoA layout and suitable prefetching. It applies to C, C++ and Rust.
