DEDUPEDWho it is forA founder asking Claude Code for a landing page who keeps getting the same gradient hero and email box.
The problemAgent-built pages fall into the same reflexes: eyebrows above every heading, one coloured word, a sign-up at the end of every page.
The outcomeA self-contained HTML and CSS page built around the visitor's job, checked at eight widths and reviewed with fresh eyes.
What you need first
- Node 18 or later
- Claude Code, Codex CLI, Cursor or OpenCode
- For the browser checks and screenshots: puppeteer-core and Chrome
Steps
- Run
npx skills add nutlope/hallmark -gto install it for every project - In Claude Code type /hallmark or simply describe a new build; in Codex use $Hallmark
- Answer the pre-flight questions and give it real material: photos, screenshots and real numbers, since nothing is invented
- Pick one of the three themes it deals, or say custom to design from your prompt alone
- Install the browser checks with
npm i -g puppeteer-coreand Chrome so it can lint the page at eight widths
Prompt for your agent
Use Nutlope/hallmark to build a landing page for <product> whose main action is <action>. Ask me for real screenshots and numbers instead of inventing any, deal three themes and let me pick, and show me the sloplint results before you finish.
Caveat. Without puppeteer-core and Chrome only the static checks run, so the eight-width render check is skipped.
