Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install comfyui-custom-node-authoring-facts

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 applies rules verified on ComfyUI's frontend and backend: hiding and serializing widgets, isolating DOM events, reusing endpoints and looking up tooltips. You avoid bugs that unit tests miss.
