Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install visual-ui-validation-subagent

First time: connect the CLI with

npx --yes palatekit@latest login

The subagent assumes the goal is not met until the visuals prove it. It reviews screenshots (responsive layouts, light and dark themes, loading and error states, accessibility) and relies on what is rendered, not on the code. The main agent calls it after a visual change.
