Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install riscv-privileged-traps-csr

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 explains M, S and U modes and key CSRs such as mstatus, mtvec and satp, then helps write a trap handler and configure PLIC and CLINT. It also covers OpenSBI integration and testing on QEMU virt.
