Substack edits and migration
Claude in Chrome edited a published Substack post, migrated a blog post from a portfolio site, and added a note to an older post.
All three tasks finished and went live correctly, including a 324-offset insertion, 18+ link conversions, and no unwanted subscriber emails on edits.
Overview
How it was set up
Claude in Chrome driving the Substack editor via screenshots, the accessibility tree, and JavaScript calls to the Tiptap/ProseMirror editor; link mapping table from a separate agent.
Worth knowing
The first insertion method merged text into the wrong paragraph and had to be undone before the second method worked.
