Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install browser-matrix-responsive-tests

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 sets the browser and device matrix, tests mobile, tablet and desktop breakpoints in parallel, then compares screenshots. You get a justified matrix and cross-browser tests to run in CI.
