What it does
Generate Brand Assets is an agent skill from crafter-station/skills. Generate OG images and favicon based on project branding. Use when: (1) user needs social media preview images for their project, (2) user wants to generate a favicon, (3) user is setting up branding assets for a website or app, (4) user has brand colors and wants professional-looking Open Graph images. Automatically generates correctly sized images optimized for social platforms (Twitter, LinkedIn, Facebook) and favicon formats.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/color-palettes.md`).
It sits in Media & Creative, covering Logo and visual identity and Social media graphics. It works with LinkedIn and X (Twitter). The repository describes itself as: Agent skills extracted from real work. Each one shipped something first. The licence is MIT.
When your agent uses it
- User needs social media preview images for their project
- User wants to generate a favicon
- User is setting up branding assets for a website
- User has brand colors and wants professional-looking Open Graph images
Example prompts
- “/generate-brand-assets”
Requirements
- Node.js
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit f0fe474. 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
Shell commands in SKILL.md call:
npxnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
cards-dev.twitter.comdevelopers.facebook.comlinkedin.com
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
Generate Brand Assets loads about 1.3k tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 377 words of instructions outside code blocks.
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.

Prerequisites
Check if you have the necessary tools:
node --version # Node.js 16+The skill uses built-in image generation capabilities. No additional dependencies required beyond Node.js.
What It Generates
- OG Images: 1200×630px preview images for social media sharing (Twitter, LinkedIn, Facebook)
- Favicon: Multiple formats (16×16, 32×32, 64×64, 192×192, 512×512) and iOS touch icons
- Manifest Icons: Web app manifest-compatible icons
- Optimized: WebP, PNG, and ICO formats for maximum compatibility
Workflow
1. Identify Brand Colors
Ask the user for their brand colors. Typical palette includes:
- Primary color (hex:
#RRGGBB) - Accent color (optional)
- Text color (typically
#000000or#FFFFFFfor contrast) - Background patterns (optional)
2. Gather Project Details
Collect information for the OG images:
- Project name
- Tagline or description (1-2 lines)
- Logo path or text-based logo preference
3. Generate Assets
Command structure:
npx generate-brand-assets \
--name "Your Project Name" \
--tagline "Brief project description" \
--primary-color "#3B82F6" \
--accent-color "#1E40AF" \
--output-dir ./public/brand-assets4. Customization Options
| Option | Example | Purpose |
|---|---|---|
--name | "My Project" | Project name for OG images |
--tagline | "Build faster" | Subtitle/description on images |
--primary-color | "#3B82F6" | Main brand color |
--accent-color | "#1E40AF" | Secondary brand color |
--text-color | "#FFFFFF" | Text contrast color |
--logo-path | "./logo.png" | Custom logo file |
--pattern | "dots" | "grid" | Background pattern style |
--output-dir | "./public" | Where to save generated assets |
--format | "png,webp,ico" | Image formats to generate |
5. Integration
For Next.js/React projects:
// next.config.js or next-seo.config.js
{
openGraph: {
images: [
{
url: '/brand-assets/og-image.png',
width: 1200,
height: 630,
}
]
},
icons: {
icon: '/brand-assets/favicon.ico',
apple: '/brand-assets/apple-touch-icon.png'
}
}For HTML projects:
<!-- index.html -->
<meta property="og:image" content="/brand-assets/og-image.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<link rel="icon" href="/brand-assets/favicon.ico" />
<link rel="apple-touch-icon" href="/brand-assets/apple-touch-icon.png" />6. Verification
Test generated images:
# Check file sizes and formats
ls -lh ./public/brand-assets/
# Preview in browser
open ./public/brand-assets/og-image.pngTest social preview:

7. Report Results
Provide the user with:
- List of generated files with dimensions
- Output directory path
- Integration instructions for their framework
- Preview links if hosting is set up
Common Patterns
Gradient Backgrounds
npx generate-brand-assets \
--name "My App" \
--gradient "from-#3B82F6 to-#1E40AF" \
--text-color "#FFFFFF"Dark Mode Support
Generate both light and dark variants:
# Light version
npx generate-brand-assets --theme light --primary-color "#3B82F6"
# Dark version
npx generate-brand-assets --theme dark --primary-color "#60A5FA"Multiple Locale Variants
For multi-language projects:
npx generate-brand-assets \
--name "My Project" \
--locale es \
--tagline "Construir más rápido"Troubleshooting
| Issue | Solution |
|---|---|
| Colors look wrong | Verify hex format is exactly #RRGGBB (6 chars) |
| Text not readable | Ensure sufficient contrast; text-color should differ from background by >50% brightness |
| Images too large | Use --optimize flag to reduce file size (trades some quality) |
| Favicon not showing | Clear browser cache and hard-refresh (Cmd+Shift+R / Ctrl+Shift+F5) |
| Output directory error | Ensure output directory exists or use --create-dirs flag |
Next Steps
After generating assets:
- Commit generated files to version control
- Update social media preview URLs in deployment
- Test social sharing on each platform (links may cache old images)
- Monitor OG image performance in analytics
