dsh-qr-toolkit
QR code & barcode toolkit for DeepSeek Harness (DSH). Two model-facing tools:
qr_decode — decode QR codes / barcodes from images (local path or http(s) URL; PNG/JPEG)qr_generate — render text/links into a QR code PNG in the session workspace
Dual-engine decoding: jsqr first (best for QR codes in screenshots), falling back to @zxing/library MultiFormatReader (QR / Code128 / EAN / UPC / DataMatrix / …). Pure JS, no native dependencies, Node ≥ 22.19.
Install
# Preferred: via the dsh CLI
dsh plugin --profile web add dsh-qr-toolkit
# Or npm into the profile dir
cd ~/.dsh/profiles/web && npm install dsh-qr-toolkit --save
Restart dsh web to activate (the package joins the profile bundle layer via dsh.bundle).
