What problem does it solve? Reviewing long documents on a screen makes deep annotation painful, and handwritten notes on an e-ink tablet are normally stranded on the device. This Skill closes the loop: it renders markdown into editorial EPUB or redline PDF formats, uploads them to a self-hosted Supernote private cloud, pulls annotated files back, and recovers what the handwriting says. ## Core Features & Use Cases - Send: Convert any markdown file into a reflowable editorial EPUB (default) or a fixed 13pt double-spaced redline PDF with a 3.5in bottom margin, then upload it to the device's /INBOX folder via the supernote cloud CLI. - Pull: Retrieve annotated work from /EXPORT — either a device-flattened PDF export or a .pdf.mark sidecar composited onto the source PDF with PyMuPDF. - Read: Dispatch an Opus subagent over per-page PNG renders of the flattened PDF to transcribe strikethroughs, insertions, and marginal notes, then merge the edits back into the source draft. - Use Case: Draft an ADR in markdown, send it to the Manta as a redline PDF, annotate it with the stylus over coffee, then run pull.sh and have an Opus pass apply the handwritten edits to the original file. ## Quick Start Send the attached markdown document to my Manta as a redline PDF so I can annotate it by hand.
