🧩 What it is / what it does
The skill brand-guidelines applies the colors and typography official from Anthropic to any artifact that would benefit from having the brand's look and feel — slides, HTML pages, PDFs, documents.
brand-guidelines is a visual identity post-processor. It doesn't create content—it takes an artifact that's already been generated and systematically applies Anthropic's official colors and fonts, ensuring brand consistency across all outputs.
The fundamental distinction: while other skills create visuals, brand-guidelines standardizes according to a single, non-negotiable corporate standard.
🎣 When it triggers
Claude invokes brand-guidelines when it detects requests related to brand colors, style guidelines, visual formatting, or company design standards.
Explicit requests: "apply Anthropic’s colors," "use the brand guidelines," "Anthropic’s corporate style."
Corporate visual formatting contexts: "match the company's standards," "official visual formatting," "applied design standards."
When the artifact (slides, HTML, PDF, document) could clearly use a brand visual identity — even if the user doesn’t explicitly mention "brand guidelines".
Keywords: branding, corporate identity, visual identity, post-processing, styling, brand colors, typography, Anthropic brand, visual formatting, visual design.
The skill activates when there is intent to apply the Anthropic-specific pattern. To create generic visual themes (any brand, any color), the right skill is theme-factory.
- ✓ Slides or PPTX need Anthropic branding
- ✓ Internal HTML docs with corporate branding
- ✓ The user mentions "Anthropic colors" or "brand guidelines"
- ✓ Presentation artifact for Anthropic context
- ✗ The user wants a custom theme (use theme-factory)
- ✗ There's no visual artifact to style
- ✗ Request is about another specific company/brand
- ✗ Context is purely textual with no visual component
🚀 How it improves your artifacts
The tangible value: any output generated by Claude has consistent brand visuals, without the user needing to specify every color or font manually.
- • Arbitrary colors with no brand guidelines
- • System default font (Arial, Helvetica)
- • Each output looks like it was made by different people
- • Manual identity review required
- ✓ Anthropic palette applied automatically
- ✓ Poppins for headings, Lora for body text
- ✓ Visual consistency across all outputs
- ✓ Ready for immediate professional use
The skill automatically selects text color based on the background: light text (#faf9f5) on dark backgrounds (#141413), dark text on light backgrounds. No manual decision is needed.
⚙️ How it works under the hood
Actual technical stack: python-pptx for manipulating presentations, RGBColor for color accuracy, and system fonts with automatic fallback.
- ✓ Uses
python-pptx RGBColorfor exact precision - ✓ Colors applied via RGB values (not hex strings)
- ✓ Color fidelity preserved across different systems
- ✓ Accent cycling: non-text shapes receive orange/blue/green in a cycle
- ✗ Poppins and Lora need to be preinstalled on the system
- ✗ Arial/Georgia fallback if fonts are missing
- ✗ Doesn't install fonts automatically
- ✗ Results depend on the runtime environment
For results with actual Poppins and Lora, install the fonts before using the skill. In environments without these fonts, the output uses Arial/Georgia — functionally correct, but visually not identical to the Anthropic standard.
💬 Practical example + Ready-to-use PROMPT
Real-world scenario: create an HTML product presentation page with Anthropic branding, ready for corporate use.
You need an HTML product page (landing page, one-pager, internal presentation) with Anthropic's official visual identity—without having to look up hex codes, choose fonts, or assemble a palette manually.
Crie uma página HTML de apresentação do produto "Claude API" para uso interno na Anthropic. Aplique as brand guidelines oficiais da Anthropic: - Paleta de cores: Dark #141413, Light #faf9f5, Orange accent #d97757, Blue accent #6a9bcc, Green accent #788c5d - Tipografia: Poppins para headings (24pt+), Lora para body text - Formas e shapes com accent cycling: orange → blue → green A página deve ter: hero section, 3 feature cards, CTA e footer. Use o look-and-feel corporativo Anthropic.
Tenho um arquivo presentation.pptx de relatório trimestral. Aplique as brand guidelines da Anthropic: - Cores oficiais via python-pptx RGBColor - Headings em Poppins (fallback Arial) - Body text em Lora (fallback Georgia) - Shapes não-texto em accent cycling: orange (#d97757), blue (#6a9bcc), green (#788c5d) Preserve toda a hierarquia e formatação existente.
On macOS: brew install --cask font-poppins font-lora. On Linux: download from Google Fonts and copy to ~/.fonts/. The skill works without them (fallback), but the result will use Arial/Georgia instead of Poppins/Lora.
🧬 Works well with / limitations
Position in the Track 2 — Identity ecosystem — and when brand-guidelines no is the right choice.
- • ONE specific brand: Anthropic
- • Fixed, immutable palette (#141413, #faf9f5, #d97757…)
- • Corporate fonts: Poppins / Lora
- • Post-processing existing artifacts
- • Predictable, standardized result
- • Any brand or visual identity
- • Palette generated/customized as requested
- • Flexible fonts, with no fixed standard
- • Creates new themes from scratch
- • Result varies by context
Use brand-guidelines when the result needs to follow Anthropic’s official standard. Use theme-factory to create design systems for any other case.
canvas-design operates at a different level: it creates visual compositions in Canvas/SVG with creative freedom. brand-guidelines and canvas-design complement each other:
canvas-design creates the visual composition → brand-guidelines applies the Anthropic palette to it. The result: creative art with a corporate identity.
If the canvas-design composition uses intentionally non-Anthropic colors (abstract art, illustration with its own identity), brand-guidelines will distort the creative intent.
- ✓ Anthropic internal presentations
- ✓ Docs and reports with corporate identity
- ✓ Product pages in Anthropic’s visual style
- ✓ Standardize outputs from multiple authors
- ✗ Create themes for other projects/brands
- ✗ Generic "dark theme" requests (use theme-factory)
- ✗ Artifacts without a visual component (plain text)
- ✗ Creative art with an intentionally distinctive identity
📋 Module 2.2 Summary
brand-guidelines applies the colors and fonts official from Anthropic — Dark #141413, Light #faf9f5, orange/blue/green accents, Poppins and Lora
Activates when the request mentions Anthropic brand colors, style guidelines, visual formatting, or company design standards
Uses python-pptx with RGBColor for precision; system fonts (Poppins/Lora) with Arial/Georgia fallbacks
Unlike theme-factory (generic themes), brand-guidelines is about ONE specific brand with a fixed palette
Accent cycling in non-text shapes: orange → blue → green, maintaining visual interest while keeping brand consistency
Works well with frontend-design, web-artifacts-builder, and canvas-design as a pipeline post-processing step
