Plugins

AI-driven drawio: four agent tools (validate, render to SVG/PNG, edit, template) plus a sidebar live board — zero-dependency mxfile-to-SVG preview, embedded diagrams.net editor with save bridge, and auto-open whenever the agent draws.

Local toolbox for the DSH web GUI: 35 pure-client tools (text, encoding, hashing, extraction, conversion, reference tables) in a sidebar view, plus the /toolbox command and config-driven agent tool exposure.

Writing bridge to the open-source QingAgent client: the agent drafts and revises documents through qing_ prefixed host tools, typeset on a rice-paper panel with mermaid, drawio, tables and KaTeX; edits stage as reviewable diffs and land only on commit, and it requires the QingAgent desktop app on the same machine.

An editable diagram canvas in the DSH sidebar plus two agent tools (diagram_read, diagram_apply) that read and edit the workspace in place, using native .drawio files: the canvas opens and saves them losslessly — cells it does not understand are preserved byte-for-byte — and a file-fingerprint revision powers optimistic locking against concurrent edits.

Standalone DeepSeek Harness plugin: preview .drawio (mxGraph XML) diagrams in the Web Sidebar

A draw.io editor as a .drawio file viewer in the DSH sidebar: diagrams are ordinary workspace files (new ones default to docs/diagrams/), edits autosave, and a file changed outside the editor is refused with a conflict bar instead of being overwritten; the editor is downloaded once from a pinned upstream release with a SHA-256 check and then runs fully offline.
