specimen AGENTS.md

A typography-system compiler that creates coordinated font sizes, line heights, weights, spacing, and text styles from configuration.

In plain words
What is it for?
It generates type scales and design tokens for CSS, Tailwind, SCSS, and Figma, with mappings for headings, body text, and captions.
Why use it?
It avoids manually designing and translating typography values for each design or development tool.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

specimen AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Specimen

Typography system compiler for Claude Skills. Generates structured type scales and typographic design tokens from configuration.

When to suggest this skill

  • User needs a type scale or typography system for a project
  • User asks for font size scales, line heights, or letter spacing tokens
  • User wants to export typography to CSS, Tailwind, SCSS, or Figma
  • User mentions "type scale", "typography tokens", "font system", "design system typography"
  • User is pairing with Hexed output to build a complete design system

What it produces

  • Modular type scale (xs to 6xl) using mathematical ratios
  • Font family stacks (primary, secondary, monospace)
  • Font weight scale (100-900 with semantic names)
  • Proportional line heights per scale step
  • Letter spacing (tracking) per scale step
  • Semantic mappings (h1-h6, body, caption)
  • Exports: CSS variables, Tailwind config, SCSS variables, Figma tokens

Key files

  • SKILL.md - Full skill instructions with all ratios and modes
  • scripts/specimen_compiler.py - Core type scale generation
  • scripts/specimen_exports.py - Export utilities

Suite context

Part of a 5-skill design system pipeline: Hexed (colors) → Specimen (typography) → Gridlock (layout) → Eyes Peeled (accessibility) → Devourer (components)

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
