Create Stunning GitHub Social Previews with Repo-Cover

Create Stunning GitHub Social Previews with Repo-Cover

Repo-Cover is a capability package designed for AI agent skills, specifically for Claude Code, Cursor, and Codex. It enables users to design a GitHub social-preview card, also known as an og:image, for a repository. The card is created as a single self-contained HTML file with just the basic details of the repository and without the need for an image model or build step.

What this skill does

• Collects metadata from a GitHub repository, such as owner, repository name, description, primary language, and license.
• Rewrites the repository description to fit within 110 characters for general text, and 60 characters for CJK languages.
• Provides four editorial moods: editorial, poster, blueprint, and gallery. By default, it applies the editorial mood.
• Exports the resulting social-preview card in a crisp PNG format at 1280x640 dimensions.
• Generates the card as a single HTML file, facilitating easy integration and sharing.

Who it is for

• Developers using GitHub who need to generate visually consistent social-preview cards for their repositories.
• Teams employing AI coding agents like Claude Code, Cursor, and Codex, who are looking to enhance their repository’s presentation.

Use cases

• Automatically generating social-preview cards to visually enhance GitHub repositories when sharing links.
• Improving the appeal of project listings by using specifically designed cards reflecting the repository’s content and style.
• Assisting development teams in maintaining consistent branding across all shared repository links.

Technical details

• Integrates directly with GitHub to pull repository details using APIs or local checkouts.
• Leverages AI capabilities in Claude Code, Cursor, and Codex for streamlined card design processes.
• Outputs are deterministic, ensuring repeatability and reliability in design execution.
