Automated summary

A design reference that lays out Ronald Mace's seven principles of universal design and how to apply them to digital products.

Strengths

  • Offers a complete, memorable seven-principle framework, each broken down into concrete criteria
  • Turns each principle into directly actionable web practices: one URL for everyone, 44px+ touch targets, captions, undo, dark mode
  • Uses vivid historical examples (OXO Good Grips, curb ramps) that make the case persuasive to a product team
  • Clearly names anti-patterns, such as treating accessibility as an afterthought or shipping separate versions for disabled users

Limitations

  • Mostly conceptual: it provides no testing method, compliance checklist or measurable success criteria
  • Does not cover precise technical standards such as WCAG, only links to related principle notes
  • Written in Spanish, so non-Spanish-speaking teams may need a translation
When to use it

Use it early in a project or during a design review to check that a screen or flow does not create barriers for diverse audiences.

When not to use it

Do not use it as a compliance or QA reference: formal accessibility audits require WCAG and testing with real users.

  • Velocidad de animación configurable

Simple e Intuitivo

  • Iconos universales
  • Navegación consistente
  • Lenguaje simple

  • Formularios cortos
  • Autocompletado

Espacio Apropiado

  • Touch targets de 44px+
  • Spacing generoso
  • Scrolling natural
  • Zoom funcional

Ejemplos

  • OXO Good Grips: Diseñado para artritis, útil para todos
  • Rampas de acera: Para sillas de ruedas, útiles para todos
  • Puertas automáticas: Accesibles, convenientes para todos
  • Subtítulos: Para sordos, útiles en espacios ruidosos

Anti-patterns

  • ❌ Diseñar para "usuario promedio"
  • ❌ Accesibilidad como afterthought
  • ❌ Versiones separadas para "discapacitados"
  • ❌ Asumir capacidades uniformes
  • ❌ Ignorar edge cases como casos raros

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/universal-design-ms47vqzj/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/universal-design-ms47vqzj' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/universal-design-ms47vqzj/download' --output '.skill-downloads/universal-design-ms47vqzj/SKILL.md.part' && mv '.skill-downloads/universal-design-ms47vqzj/SKILL.md.part' '.skill-downloads/universal-design-ms47vqzj/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/universal-design-ms47vqzj/SKILL.md' && test -s '.skill-downloads/universal-design-ms47vqzj/SKILL.md' && mkdir -p '.agents/skills' && test ! -e '.agents/skills/universal-design' && cp -R '.skill-downloads/universal-design-ms47vqzj' '.agents/skills/universal-design'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/universal-design-ms47vqzj'

openskills read 'universal-design-ms47vqzj'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/universal-design-ms47vqzj/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
