Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install bare-metal-uart-serial

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 calculates the baud rate, writes polled or interrupt-driven transmit and receive with a ring buffer, and retargets printf to UART with newlib. It also helps fix garbled or missing characters.
