substack-articles

Mirror a Substack article into the In the Weeds public learning repo at `~/in-the-weeds-substack-articles/`. Handles two source modes - local (slug from `~/hannah-personal-agent/`) and firecrawl (URL from any Substack-hosted post). Copies article + images, generates the article-level CLAUDE.md, cascades index updates across root CLAUDE.md, series CLAUDE.md, welcome.md, CONTRIBUTORS.md, and LICENSE, then opens a clean PR. Use this skill whenever Hannah says "add this article to in-the-weeds", "publish [slug] to the repo", "mirror [URL] into the learning repo", "add the [slug] article", or runs /add-substack-article-to-repo. Also use when she pastes a Substack URL (https://...substack.com/p/... or any /p/ pattern) and asks to bring it into the repo.
