What problem does it solve? Sharing code snippets from GitHub on social media usually requires manual screenshotting, formatting, and copywriting, and risks leaking secrets embedded in the code. This Skill automates the entire pipeline from URL to publishable card image and platform-ready copy. ## Core Features & Use Cases - GitHub Snippet Extraction: Parses blob or raw GitHub URLs, including #L10-L25 line fragments, and fetches the exact line range (capped at 80 lines) from public repositories. - Security Scrub Gate: Routes every snippet through a security-scrub skill that blocks the workflow if secrets are detected, preventing accidental credential leaks. - Card Generation & Copy Drafting: Fills an HTML template with HTML-escaped, syntax-highlighted code, renders a dark-mode PNG via Playwright, and drafts platform-aware copy for LinkedIn, Twitter/X, Bluesky, or Substack. - Use Case: You find a useful TypeScript pattern in an open-source repo and want to share lines 10-25 on LinkedIn — provide the URL and receive a scrubbed, rendered card image plus ready-to-post copy saved to docs/media/social/. ## Quick Start Share the code at https://github.com/owner/repo/blob/main/src/utils.ts#L10-L25 as a LinkedIn post with a snippet card image.
