dsh-openpencil Repo Summary
dsh-openpencil is the OpenPencil plugin (DSH plugin) for DeepSeek Harness (DSH), connecting DSH with OpenPencil so an Agent can drive a real, editable, interactive design canvas inside a conversation instead of returning a generated image. It solves the pain point of design document preview and editing: previously, agents could only output images, unable to view or modify real documents. The plugin provides exact multi-frame previews, an interactive canvas, a managed editor, and agent-native design tools. It is maintained by ZSeven-W, licensed under MIT, and last updated in 2026-08.
What core features does the dsh-openpencil DSH plugin support?
dsh-openpencil offers five core capabilities: Exact Multi-Frame Previews render design-faithful previews via a headless exporter, including a large first-frame image, a horizontally scrollable thumbnail rail, click-to-select, and previous/next navigation; Interactive Canvas lazily mounts the read-only OpenPencil Web SDK with pan, zoom, and fit, allowing inspection of any page or nested node without leaving the conversation; Managed Editor opens a resizable right-hand workbench when editable: true, providing selection, layers, properties, drawing tools, undo/redo, and explicit save semantics; Agent-Native Design Tools include five tools — openpencil_new, openpencil_create, openpencil_edit, openpencil_render, openpencil_selection — that let the Agent create, modify, and read a real canvas through transactional batch_design programs; Capability-Gated Grants ensure security.
How do I install dsh-openpencil?
Installing dsh-openpencil requires a single command in your DSH environment:

After installation, the plugin automatically registers its tools and UI, ready to use in conversations without extra configuration.
