Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install bare-metal-startup-code

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 describes the boot sequence from reset to main(), then writes the vector table, .data and .bss initialisation, the stack, and the link with the linker script. It also helps diagnose firmware that never reaches main().
