What it does

Flexible Typography is an agent skill from Owl-Listener/inclusive-design-skills. Design typography systems that adapt to user needs — scaling, spacing, and font preferences. Use when designing type systems, setting font sizes, defining line heights, or reviewing text readability across conditions. Triggers on: typography, font size, line height, letter spacing, word spacing, text scaling, dyslexia font, readable font, type scale, font units, rem, em, px, reading difficulty.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Typography. The repository describes itself as: Inclusive design skills for AI coding agents — from cognitive accessibility to adaptive interfaces, inclusive research, and accessibility decision-making. The licence is MIT.

When your agent uses it

  • Designing type systems
  • Setting font sizes
  • Defining line heights
  • Reviewing text readability across conditions

Example prompts

  • “/flexible-typography”

What it can do on your machine

Read from SKILL.md and the folder at commit 6e0740f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flexible Typography loads about 865 tokens when it runs. Until then it costs about 104 tokens; SKILL.md has 434 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~865

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Design typography systems that adapt to user needs — scaling, spacing, and font preferences. Use when designing type systems, setting font sizes, defining line heights, or reviewing text readability across conditions. Triggers on: typography, font size, line height, letter spacing, word spacing, text scaling, dyslexia font, readable font, type scale, font units, rem, em, px, reading difficulty.

Flexible Typography

Design type systems that flex with the user — scaling smoothly, spacing generously, and never breaking when someone needs text larger, more spaced, or in a different font.

Core Requirements

Relative Units Always
  • Use rem for font sizes (relative to root, user-controllable)
  • Use em for spacing that should scale with text
  • Never use px for font size — it overrides user preferences
  • Base font size: let the browser default (usually 16px) be your starting point, don't override it
Minimum Sizes
  • Body text: 1rem minimum (never smaller)
  • Small text / captions: 0.875rem minimum
  • Labels and UI text: 0.875rem minimum
  • If text is essential, it should be readable without zooming
Line Height
  • Body text: 1.5 minimum (WCAG requirement)
  • Headings: 1.2–1.3 (tighter is acceptable for large text)
  • Line height should scale with font size — use unitless values (1.5 not 24px)
Spacing
  • Paragraph spacing: at least 1.5× the font size
  • Letter spacing: don't compress below browser default
  • Word spacing: don't compress below browser default
  • Users must be able to override spacing without breaking layout (WCAG 2.1 Level AA, Success Criterion 1.4.12)

Design Patterns

Scalable Type Scale
  • Define a type scale using relative ratios (1.25, 1.333, 1.5)
  • Each step should be perceptibly different
  • 4–6 sizes is enough for most interfaces
  • Example: 0.875rem, 1rem, 1.25rem, 1.5rem, 2rem, 2.5rem
User-Override Safe
  • Don't set fixed heights on text containers
  • Use min-height instead of height for elements containing text
  • Let containers grow when text grows
  • Test with: 200% text size, 200% zoom, extra letter and word spacing
  • If layout breaks at any of these, the CSS needs fixing

Font Selection
  • Prioritise readability over aesthetics
  • Sans-serif fonts are generally easier for screen reading (but this is preference, not rule — test with your audience)
  • Ensure the chosen font has:
    • Clear distinction between similar characters (Il1, 0Oo, rn/m)
    • Consistent x-height
    • Adequate character spacing at default settings
  • Provide a font-family stack that degrades gracefully
  • Never prevent users from overriding with their preferred font
Dark Mode Typography
  • Reduce font weight slightly in dark mode (light text on dark backgrounds appears heavier than dark text on light)
  • Ensure contrast meets 4.5:1 minimum in both modes
  • Avoid pure white (#fff) on pure black (#000) — the extreme contrast causes halation for some users. Use off-white on dark grey instead

Assessment Checklist

  • All font sizes use rem or em, never px
  • Body text is at least 1rem
  • Line height is at least 1.5 for body text
  • Layout survives 200% text scaling without breaking
  • Layout survives user-applied letter and word spacing overrides
  • Text containers use min-height, not fixed height
  • Font has clear character distinction (Il1, 0Oo)
  • Both light and dark modes meet contrast requirements
