Record every step the agent took, and walk through it forwards and backwards to find where it went wrong.

Browser automation connector: drives the local Edge or Chrome over the DevTools Protocol with zero runtime dependencies — launch a headless throwaway-profile browser or attach to one started with --remote-debugging-port, then navigate, read page text and interactive elements, click, type, and screenshot through 11 agent tools.

Preview native WeChat Mini Programs in the DSH sidebar with a local runtime and WXML source locations.

Wire-level LLM inspector: captures the raw HTTP request and response bodies of model provider calls and attributes each capture to the session that caused it through the llm/stream waterfall. The request pane renders the body as a collapsible tree with per-node sizes — one measured request was 98.6% a single 973-entry array — and the response pane reassembles the OpenAI-style SSE chunk stream into reasoning, content, tool calls and usage. Shown in a Conversation View tab and a loopback viewer page.

Preview, debug (logs and screenshots), and publish WeChat Mini Games inside the dsh Web GUI, through the official mini game helper service

Turn the DeepSeek Harness Web UI into a real desktop application from inside DSH: one plugin that provisions a portable launcher (native WebView2 window, tray residency, silent backend start, readiness gating, debug console) plus desktop/start-menu shortc

Ships a skill that documents how to build, debug and publish DSH plugins - host and client package skeleton, developing a forked plugin inside a throwaway profile, publishing to GitHub and npm, and the pitfalls found while shipping them. Installing the plugin registers the skill.

Makes ctx.logger output visible: a /logs chat command over a full-capture ring (level, name, grep, since filters) plus a default-on stderr exporter for warnings and errors, configurable per plugin; works headless. Also documents that dsh's default log buffer silently drops warn and debug records.

From chat to canvas to artwork — drive ComfyUI as a visual workflow IDE inside DSH. Embed ComfyUI (local or cloud) as a split-screen canvas in DeepSeek Harness Web: the agent sparks ideas, writes prompts and scripts right in the chat, applies them live to the canvas in front of you, and produces images, music, video, and 3D. From idea to finished output without ever leaving the conversation or switching front-ends: Canvas ops — compose and arrange pipelines, read/write workflows, edit nodes, wire links, run, tune parameters, and debug errors, all live and WYSIWYG on the exact canvas you are looking at; Production tasks — batch parameter sweeps (batch_run) and automatic output-image retrieval back into the chat (get_outputs), powering multi-modal creative and batch generation across images, music, video, and 3D; Environment upkeep — one-click launch of ComfyUI and one-click upgrade of the core plus every custom node (upgrade), keeping the stack healthy without interruption. This package is the DSH-side plugin, and it ships the ComfyUI-side bridge node too.
