02 · Long Document

Reads like a memo, a letter, or a journal entry. No marketing structure. Continuous prose with inline section heads. The page is literature about the product.

  • Heading: inline with body — section heads emerge from the paragraph flow as small caps or bold short phrases.
  • Body: single column, generous line-height (1.65+), measure 60–65ch.
  • Divider: negative space; the gap is the divider; occasionally a centered ornament for emphasis.
  • Button: typographic link inside a paragraph, not a separate block.
  • Image: inline, sized to text measure; never full-bleed.
  • Reveal: none. The page is just there.

Reach for it for case studies, founder posts, mission pages, products whose sale is philosophical. The brief is "tell a story", not "list features".

Avoid when there's a single decisive action to take — Long Document hides CTAs, which is wrong for transactional pages.

Reference: Frank Chimero's site, destroytoday.com, long-form Substack essays in product disguise.

Sample opening lines (imitate the specificity, not the wording):

"Saturday, 6:14 a.m. The dough went in at midnight." — opens with a time-stamp; the brand introduces itself as a moment in the day "A monthly art publication featuring contributions by some of the most engaged thinkers working today." — e-flux.com/journal "We design everything for everyone." — pentagram.com — refusal of the verb, treats design as universal practice

    The hallmark skill is a design-focused extension for AI agents that facilitates the creation of professional user interfaces by preventing 'slop' patterns. It provides tools for auditing, redesigning, and studying design elements from screenshots or live URLs. The skill demonstrates robust security awareness, including a comprehensive remote URL safety check and explicit instructions to handle external data as inert to prevent indirect prompt injection. No malicious patterns, such as credential theft, persistence mechanisms, or unauthorized code execution, were identified during the analysis.
