dsh-qrcode

An offline QR code and barcode generator for DeepSeek Harness. Pure local computation — no network, no shell, no dependencies.

Overview

DeepSeek Harness sessions often run with restricted network access (no npm, no CDN, no online encoder APIs), so generating a scannable code from inside a session is not trivial. This plugin solves that: it provides qrcode and barcode model tools that encode and render entirely locally, with zero runtime dependencies. It is for agents and users who need QR codes (URLs, WiFi, vCard, tel, sms) or 1D barcodes (Code128, EAN-13) as SVG / PNG / ASCII output inside any DSH session — including fully offline or sandboxed ones.

Quick start

Tell the agent:

把这个链接做成二维码: https://example.com

or call the tools directly:

qrcode text="https://example.com" format=svg
barcode text="ABC-123" symbology=code128 format=svg

qrcode returns SVG markup (save to a .svg file), PNG data URLs, or ASCII previews. barcode supports code128 and ean13.
