Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install client-side-dom-security-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 finds risky entry points (markup injection, iframes with postMessage, service workers, CSS injection) and checks how data reaches dangerous sinks. It applies the authorization gate before any active test. You get a list of signals and checks to validate.
