Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install os-from-scratch-x86

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 walks you through the boot steps, from the bootloader to long mode, page tables and interrupt handlers, up to a minimal kernel tested in QEMU. It relies on tools such as limine, Multiboot and x86_64-elf-gcc.
