10 · Specimen (no longer the default)

Numbered left-margin labels, huge serif display, asymmetric column spans, hairline rules, typographic-only CTA, generous whitespace. Editorial / type-foundry energy.

  • Heading: left-margin number + label (01 — HELLO.) beside a large serif phrase.
  • Body: asymmetric spans — narrow label column / wide content column.
  • Divider: hairline rules between sections.
  • Button: typographic link with arrow ("Open your studio →"); no box, no fill.
  • Image: none, or a hand-drawn SVG accent in the wide left margin.
  • Reveal: fade-up stagger on first load.

Reach for it ONLY when the brief is explicitly editorial, type-foundry, journal, or "specimen sheet". Otherwise pick something else.

Banned as a default. If the brief is vague and you've defaulted here, restart.

Reference: type foundry homepages (Klim, Pangram Pangram, Production Type), some editorial portfolios.

Sample opening lines (imitate the specificity — Specimen openings are foundry-voice, treating type as material culture):

"A thing well made." — klim.co.nz — refusal of the verb, treats design as material "Type, set with care." — Hallmark Specimen — three words, a colon implied "Creative direction, design and type for culture since 2003." — apracticeforeverydaylife.com — date-anchored, names verticals

    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.
