An automatic proofreader for a whole website. One command reads every page and lists what should never go live: a title cut in the middle, a paragraph copied from another page with the numbers changed, an empty section, a link that leads nowhere, a figure with no source. Sixteen checks, thirteen seconds on 1,660 pages, and an eight-page PDF that explains each one. Free and MIT, nothing leaves your computer. It reads Markdown files: Astro, Next and MDX sites, not WordPress. npx @operstack/gates
