Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install spi-uart-can-i2c-debugging

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 separates electrical, framing, driver and application causes, then picks a minimal transaction to compare the actual capture with the expected behaviour. It takes SPI mode, chip-select timing and DMA into account. You get a diagnosis backed by evidence.
