dsh-with-pencil

In DeepSeek Harness, a design task often cannot stop at a text reply. You may need to see the canvas, inspect nodes, check visual details, and then keep refining with the model. dsh-with-pencil brings official pen.dev Pencil editing into Harness, letting DeepSeek remain the design Agent while model tools, the active conversation, and the Pencil canvas work together. It is not a standalone design product or a rewrite of Pencil, but a bridge built for the Harness workflow.

Its core value is making the canvas part of the conversation. The Pencil canvas opens on demand, hides when you switch conversations, and returns with its previous editor state when you come back. Agent edits go through the visible editor for live rendering and confirmed atomic saves. The plugin also supports screenshots, node inspection, selection context injection, PNG/PDF export, image insertion, design libraries, and conflict handling, so visual checks do not rely on blind edits.

This plugin is well suited for people who create .pen designs, interface drafts, or graphics iterations inside DeepSeek Harness and want the Agent to participate directly in canvas editing and visual verification. It is especially useful for Harness users who want Pencil to move beyond described edits into a collaborative, visible design workspace.
