In the Skill's Own Terms

This skill applies Anthropic's official brand identity to artifacts by enforcing a specific color palette and typography system. It uses Anthropic's main colors (Dark #141413, Light #faf9f5, Mid Gray #b0aea5, Light Gray #e8e6dc) and accent colors (Orange #d97757, Blue #6a9bcc, Green #788c5d).

Typography follows a two-font system: Poppins for headings 24pt and larger, Lora for body text, with Arial and Georgia as fallbacks. The skill cycles through accent colors for non-text shapes and selects text colors based on background contrast. It works with system-installed fonts and provides automatic fallbacks, maintaining brand fidelity without requiring font installation.

See the example prompt ↗

How It Works

01
Apply Heading Font to Large Text
The skill identifies text 24pt and larger and applies Poppins font, falling back to Arial if Poppins is unavailable.
02
Apply Body Font to Standard Text
Body text receives Lora font with Georgia as a fallback to preserve readability across systems.
03
Select Text Color by Background
The skill chooses appropriate text colors from the brand palette based on the background color to maintain readability.
04
Cycle Accent Colors for Shapes
Non-text shapes receive accent colors rotating through orange, blue, and green to maintain visual interest.
05
Match Colors Precisely via RGB
Brand colors are applied using RGB values through python-pptx's RGBColor class for exact color fidelity.

When to Use the brand-guidelines Skill

Use the brand-guidelines skill in Claude Code or Codex when the job is brand and design-system work of this kind. Fit and limits below are taken from the skill's own file.

Good Fit

Work requiring brand colors or style guidelines
Documents needing corporate identity or visual formatting

Know the Boundaries

Environments where Poppins and Lora fonts are not pre-installed will see fallback fonts instead of optimal brand appearance

03 Inside the skill

Rules the brand-guidelines Skill Gives Claude Code and Codex

5 concrete instructions, defaults and limits the SKILL.md sets for the agent — the part of the file that changes the result.

24pt Threshold for Heading Font
Text must be 24pt or larger to receive Poppins font treatment. Smaller text gets Lora body font.
Mandatory Fallback Fonts
Arial must be used as fallback for headings and Georgia for body text when custom fonts are unavailable.
Exact Hex Values for All Colors
Main colors are Dark #141413, Light #faf9f5, Mid Gray #b0aea5, Light Gray #e8e6dc. Accent colors are Orange #d97757, Blue #6a9bcc, Green #788c5d.
Preserve Text Hierarchy
The skill must maintain existing text hierarchy and formatting while applying brand fonts and colors.
No Font Installation Required
The skill works with existing system fonts and does not require or perform font installation, though pre-installed fonts yield best results.
