Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install layer-2-network-discovery

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 relies on LLDP, ARP and MAC vendor lookup to find the switch port of a server or identify an unknown device. You get the local segment's topology and the commands to run.
