typography

typography is a skill for Claude Code, Codex from clubpay/ronykit. It costs 77 tokens per session (1,617 once invoked), scanned A, original, BSD-3-Clause.

A guide to setting visible text correctly in web pages and applications, covering quotation marks, dashes, spacing, line length, line height, and text hierarchy.

In plain words
What is it for?
Use it when creating or reviewing HTML, CSS, React, or JSX text, choosing readable line lengths, and fixing punctuation or text-spacing details.
Why use it?
It prevents common typography mistakes that make interfaces, documentation, and other text-heavy screens look inconsistent or poorly typeset.

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

typography 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 4d ago.

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.

Typography

These are durable craft rules, not trends — distilled from Matthew Butterick's Practical Typography. They're the difference between text that looks typeset and text that looks auto-generated. Apply them silently by default when producing UI text; in review mode, flag violations with before/after fixes.

frontend-design chooses the typefaces and mood; this skill governs the correct setting of whatever type is chosen. Use design-tokens for the type scale, and dashboard-ui for tabular figures in data tables.

When to use

  • Generating any HTML/CSS/React/JSX containing visible text.
  • "Make this look professional", a design/typography review, or fixing legacy copy full of straight quotes and --.
  • Setting body text, line length, hierarchy, or a type scale.

Characters — the high-frequency fixes

Use the real character; never approximate. (Full table: references/html-entities.md.)

Wrong Right Entity When
"straight" "curly" &ldquo; &rdquo; All double quotes
'straight' 'curly' &lsquo; &rsquo; All single quotes
it's it's &rsquo; Apostrophe = closing single
-- &ndash; Ranges (1–10), connections
--- &mdash; Sentence breaks—like this
... &hellip; One ellipsis character
(c) (TM) (R) © ™ ® &copy; &trade; &reg; Real symbols
12 x 4 12 × 4 &times; Multiplication
  • Apostrophes always point down (&rsquo;), including before decades (&rsquo;70s) and rock &rsquo;n&rsquo; roll — smart-quote engines get these backwards.
  • Foot/inch marks are the one exception — they must be straight: 6&#39;&nbsp;10&quot;.
  • One space after punctuation, never two. Use &nbsp; to glue references (&sect;&nbsp;42, Fig.&nbsp;3, &copy;&nbsp;2025).

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.
