Canvas-Pro for DeepSeek Harness: a Web drawer plus eight model tools for creating, patching, versioning, and exporting canvas artifacts.
After install, the Web session header gets a Canvas button. The agent can create HTML, Markdown, Mermaid, SVG, or React artifacts; the drawer previews them in a sandboxed iframe.
Model tools:
| Tool | Purpose |
|---|---|
create_canvas_artifact | Create an artifact |
update_canvas_artifact | Patch by selection, line range, or overwrite |
get_canvas_selection | Read the latest preview selection |
get_canvas_artifact | Read current content |
list_canvas_versions | List snapshots |
revert_canvas_artifact | Restore a previous snapshot as a new version |
diff_canvas_artifact | Unified or split diff between versions |
export_canvas_artifact | Export markdown, html, svg, png data URL, or json |
Selecting text in the preview opens Explain / Refactor / Fix / custom prompt actions and submits them into the current chat.

| dsh-live-canvas | dsh-canvas-preview | dsh-generative-ui | Canvas-Pro | |
|---|---|---|---|---|
| What it is | Live sandbox for HTML / React / Vue / SVG / Mermaid / Markdown | Conversation tab that previews workspace HTML | Streaming TSX UI inline or in a side canvas | Artifact workspace: drawer + eight model tools |
| Agent tools | Preview-oriented | canvas_preview-style HTML preview | Agent writes TSX; cards can run bash / curl / model / files | create / update / get / get_selection / list_versions / revert / diff / export |
| Partial edit | Not the product focus | Typically whole HTML | New TSX frames | replace_selection, replace_range, full_overwrite |
| Selection → next turn | DOM click inspector | Not listed | Click on a card drives the next chat turn | Explain / Refactor / Fix / custom prompt from a text selection |
| Versions | Side-by-side visual diff | Not listed | State kept across stream frames | Snapshot history, revert as a new version, unified and split line diff |
| Export | Vite ZIP | Local PNG / JPG / SVG | Not listed | Markdown, standalone HTML, SVG, PNG rasterization (SVG fallback), JSON archive |
| Persistence | Session / HMR | Workspace HTML files | In-memory UI state | $DSH_HOME/storages/canvas-pro/artifacts.json |
| Drawer | Preview surface | Conversation tab | Inline + side canvas | Resizable overlay; chat turns do not force it open |
