Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install agent-ui-testing

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 climbs the test levels only as far as the bug requires: protocol checks with MCP Inspector, rendering in a test host, then a tunnel to a real host. You get useful assertions and a table of causes per symptom.
