SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Crossposting a single Beehiiv newsletter article across multiple social platforms is time-consuming and error-prone, especially when each destination requires different formatting, image handling, and posting flows.

Core Features & Use Cases

  • Full-article syndication: Publishes the full newsletter content with preserved formatting and images to LinkedIn, Substack, and Medium, including setting the canonical URL back to the Beehiiv original.
  • Link submission: Submits a link plus title/short context to Hacker News and Reddit, with Reddit supporting multi-subreddit posting and required flair handling.
  • Image + content pipeline: Extracts article body and images from Beehiiv, normalizes HTML for paste-based editors, and downloads/uploads images per platform flow.
  • Reliability guardrails: Performs pre-flight checks, uses authenticated browser automation where needed, and includes structured edge-case labels for common publishing failures.

Quick Start

Run /crosspost-newsletter with your Beehiiv post URL to cross-post the article across LinkedIn, Substack, Medium, Hacker News, and Reddit.
