Plugins

DSH Session Manager: manage conversations, archive/restore, delete safely, open record folders.

Talk to Excel in DeepSeek Harness: create, edit, repair, and verify spreadsheets by conversation, with automatic formula health checks after every edit.

Reads DSH conversations aloud using the DeepSeek web page's built-in read-aloud, driven by a small browser extension.

Adds /review, /review-status, and /review-cancel to spawn an independent native subagent that inspects a chosen Git scope (base branch, uncommitted changes, a commit, or custom instructions) and returns a findings report in the current conversation, with English or Chinese output from the host locale.

Font plugin for the DeepSeek Harness Web GUI: the conversation gets its own font, size, line height and weight, the interface has a font and a weight of its own and follows the conversation by default, code keeps its own axis with ligature control, and whole setups save as presets.

Lightweight Markdown conversation theme plugin — enhances native color scheme with 4 built-in themes (light/dark dual), user-defined CSS themes, system-aware auto-switching, in-browser theme editor, designed to enhance reading speed and clarity.

Learns what you leave unsaid in your prompts from messy turns and your own corrections, and injects the learned directives into the system prompt of every new conversation; the directives are editable in Settings and a composer button rewrites the current draft with them.

Register locally-defined custom agents as callable subagents in dsh: the main conversation invokes any agent by name via use_agent, each running as a real dsh subagent with its own persona. Supports breakpoint resume for interrupted runs.

Adds a take screenshot tool plus two optional automatic capture points, putting the screen into the conversation as an image block; requires an image-capable model.

AgentDuel is a code-battle game. This plugin lets you complete the entire game loop inside DSH: manage deathmatch characters and capture-the-flag teams, submit agent code, start battles, watch replays, and use DSH conversations to keep improving agents based on battle results.

User Message Timeline - floating pill rail with hover preview, click/drag jump and pagination, switchable left/right.

Conversation history rail on the left edge of the chat: each tick is one real user request, hover to preview its text, click to jump to that turn.

An Aether Gazer Verdandi-inspired DSH Web UI skin with light and dark backgrounds, wedding-themed chrome, responsive character art, and themed conversation and sidebar surfaces.

Game-style floating HUD: balance HP bar, context MP bar, official peak/valley pricing with countdown, auto-compaction under 5% remaining, and memory-carrying new conversation.

Custom background image for the DSH Web UI: upload a picture or paste an image URL behind the whole app surface, with opacity, theme-aware scrim, panel transparency, frosted-glass and wallpaper blur, live preview and persisted settings, plus an optional DeepSeek-style timeline rail with per-question bookmarks for long conversations.

Shows a floating toolbar above text selected in a conversation, with copy, quote, ask, explain, translate, summarize, and custom prompt actions.

Session timeline down the left of the conversation: every user message at a glance, current-message tracking, hover preview of the message and its reply, click to jump, collapsible.

Conversation Canvas tab: live-preview workspace HTML artifacts and export PNG/JPG/SVG locally (`npx dsh-canvas-preview`).

DeepSeek Harness conversation outline plugin (对话目录)

Edit any user turn in DeepSeek Harness and re-run it: an inline editor on the message row rolls the conversation back to just before that turn through the official surface-replace contract, then re-prompts the agent with the revised text. The append-only

Give the dsh agent a real browser: each conversation gets its own Chrome or Edge process with its own profile and CDP port, driven by six tools and mirrored live in the right sidebar, where you can watch the work and take over by clicking or typing on the picture. Nothing else to install — it uses the Chrome or Edge already on the machine, downloads no browser, needs no companion app or extension, and keeps its tabs and sign-ins between tool calls.

Feishu/Lark gateway for DeepSeek Harness with topic-persistent conversations, live execution cards, image and file inputs, in-chat approvals and questions, source allowlists, and durable one-time or recurring agent tasks created in natural language.

Conversational GIS for the DSH Web UI with local file and PostGIS querying, interactive maps, and spatial analysis.

Adds /btw for one-off, context-aware side questions without tool execution, with independent answer bubbles that can be copied, collapsed, or closed without adding answers to the main conversation.
