Before you start
In Claude Code, install both. Landing Page Builder: /plugin marketplace add alirezarezvani/claude-skills, then /plugin install landing@claude-code-skills. Antislop: /plugin marketplace add https://github.com/miqdadbadjuber/anti-slop, then /plugin install antislop@anti-slop. Antislop is a filter, not a style guide: for a page you plan to ship, put your visual direction in a DESIGN.md, or the result is labelled a draft.

The builder includes a brand palette validator with WCAG contrast checks.
Say to Claude CodeCheck that these brand colours pass WCAG contrast before you build the page: [primary hex], [accent hex], [background hex].
Build the page
It asks four questions one at a time: the product and pitch, the audience, your brand colours and the tone. Answer with what is true. The page has a hero, feature cards and a closing call to action.
