Brand Guidelines Skill - Keep Claude Output On-Brand

Source: Content adapted from anthropics/skills (MIT). Last synced July 8, 2026, against the April 20, 2026 upstream update.

Overview

The official description: "Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply."

This is the reference example of a corporate identity skill: it encodes one company's design system so every artifact Claude produces stays on-brand. Swap in your own values and you have a brand skill for your team.

How the skill works

The SKILL.md is a compact design-system spec:

• Colors - Anthropic's official palette with usage roles (backgrounds, text, shapes, accents)
• Typography - the approved font stack with smart font application rules
• Features - text styling conventions and shape/accent color application
• Technical details - font management and color application mechanics, so the rules survive across HTML, slides, and documents

What's inside the skill folder

• SKILL.md (~2 KB - one of the smallest official skills)
• LICENSE.txt

Key takeaways for your own skills

• A brand skill doesn't need to be big: 2 KB of precise tokens beats 20 KB of prose.
• Encode roles ("accent", "background"), not just hex values - that is what lets Claude apply the system to artifact types you didn't anticipate.
• This pattern is the fastest win for teams: fork it, replace the palette and fonts, done.
