What it does.
Runs a strict, judged design QA pass — like a linter for visual and UI rules — instead of a vague “does this look ok?” glance.
When to invoke it.
Invoke it when you want pass/fail design feedback in the agent, not a stroll through the live page in a browser.
Install it first.
Follow How to install portable skills, then the platform how-to for your host. Get the file from design-lint — never treat GitHub as the primary button.
Shop page versus browser tool.
This pack is skill-only. There is no matching browser tool on /tools. The shop page is for copy and download.
The shop page is Setup only.
