Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install codex-browser-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

For a non-OpenAI model in the Codex app, the agent initializes the browser runtime, opens a page, clicks, types text, then reads the page state or takes a screenshot. You get a visual check of a local application.
