What problem does it solve?

This Skill lets you quickly grab a public Substack article by URL and convert it into clean, offline-friendly Markdown with locally stored images, so you can plug it into your pipeline without manual copying.

Core Features & Use Cases

  • Public Substack fetching: Downloads Substack article HTML via plain HTTP (no Chrome, no login) and extracts the main article body.
  • Readability + Turndown cleaning: Produces Readability-cleaned Markdown and normalizes structures like figures and captions.
  • Local image localization: Downloads remote images into RAW_DIR/<slug>/assets and rewrites image links to relative paths.
  • Metadata in YAML frontmatter: Writes title, author, url, fetched date, optional published date, optional tags, and optional excerpt into the Markdown header.

Quick Start

Ask for: fetch this Substack article from the given URL and save the cleaned Markdown plus local images under RAW_DIR (absolute path) using this skill.
