Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install linux-kernel-locking-rcu

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 follows a decision tree to pick a spinlock, mutex, semaphore, RCU, seqlock or completion for the context. It also helps write IRQ-safe sections and fix 'scheduling while atomic' errors or deadlocks.
