Blog Cover Generator Skill
This skill provides AI agents with the ability to generate stunning, minimalist, technical blog cover images using the blog-cover-image-cli. The CLI leverages Gemini 3.1 Flash Image Preview, automatically fetches brand logos from domains, uses local aesthetic reference images, and employs Google Search grounding to inject real-time context.
Setup & Configuration
Agent Pre-requisites:
Before using this tool, verify it is installed. If blog-cover-cli --help fails, install it globally:
npm install -g blog-cover-image-cli
If the user wants you to generate an image and you haven't set up the API key yet, you must first configure the CLI using a Gemini API Key. The CLI stores this securely via the conf package.
npx -p blog-cover-image-cli blog-cover-cli config set-key <YOUR_GEMINI_API_KEY>
npx -p blog-cover-image-cli blog-cover-cli config set-brandfetch-id <YOUR_BRANDFETCH_CLIENT_ID>
npx -p blog-cover-image-cli blog-cover-cli config get-key
npx -p blog-cover-image-cli blog-cover-cli config get-brandfetch-id
Usage: Generating an Image
When a user asks for a cover image (e.g., "Create a cover image for my blog about Vercel v0"), you should use the generate command.
npx -p blog-cover-image-cli blog-cover-cli generate -t -l
