Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install spi-i2c-master-drivers

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 writes SPI transfers with clock phase and polarity, and I2C START, ACK and STOP sequences to read sensor registers. It also helps diagnose NACKs and stuck SCL lines.
