The plugin market
inside DeepSeek Harness

The official billion-context plugin: a context-compression plugin for small context windows (a 100K context is enough), token savings (5x fewer tokens), and month-long single sessions (billions of tokens).

Rebuilds the DeepSeek Harness web sidebar, workspace tree, search, and turn navigation in a Codex-style layout.

Full sidebar workbench with file rendering and editing, terminal, Git, and subagents; third-party plugins can register new tabs.

Manages local DeepSeek Harness skills in Settings and shows shared Agent skills as read-only.

Adds an archived-sessions page in Settings to search, restore, and delete archived DeepSeek Harness sessions by workspace.

A fixed-corner whale widget for the DSH web GUI — balance, today's usage and per-turn cost with peak/off-peak pricing, editable balance-alert and daily-budget bubbles, a module-based custom bubble queue with A/B weighted choices and random lines or images, 30+ vendor templates (OpenAI, OpenRouter, Kimi, SiliconFlow, Ark, Zhipu, MiniMax and more) with per-model balance and subscription quota, plus task-end sound, imported audio, custom roles and a resource manager. Local-only, no telemetry.

Skill center for the dsh web GUI: browse all loaded skills grouped by source, enable or disable model invocation, create new skills, and delete into a recoverable trash.

A whale-girl companion for the dsh web GUI: animations follow the agent state, with pat interactions and a feeding mechanic that raises intimacy from a calf to deep-sea bonds.

Adds a summonable domain-expert roster that runs as subagents while the parent session keeps the task and final answer.

Remote control of a dsh web workspace from phone or PC: QR-code pairing through a token-gated channel, SSE real-time sync, and separate mobile and full desktop GUI modes.

Task board for the dsh web GUI: a sidebar multi-column kanban whose cards run in real DSH agent sessions and can also be scheduled with cron expressions, executed host-side even with the browser closed.

DSH context insight panel: Context dashboard + /context command + Context browser — one-stop context lifecycle management with categorized composition, content details, evolution trends, compaction/injection events, and stats.

Git branch selector and Git graph for the dsh web GUI: switch branches and explore branch-lane and commit history from the conversation header.

Connects WeChat, WeCom, DingTalk, Feishu, Lark, QQ, and Telegram to a local DeepSeek Harness agent, with each IM chat as a separate workspace channel.

SSH ops panel for DSH: web terminal, SFTP transfer with progress, local port forwarding, and one-command cluster execution across hosts; agents share the same host config.

Runs scheduled coding tasks in isolated DeepSeek Harness sessions, managed from Settings or the agent.

Plugin and skin collection for the DSH Web UI: task board, Git graph, right-side panel, remote mobile UI, pet, live token stats, and a skin center.

Per-session and daily API cost, budget with usage %, official balance, history dashboard, and one-click official price sync with peak/off-peak pricing.

Vision bridge for text-only models: paste an image, get structured JSON evidence (OCR, layout, semantics).

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.

Adds a /simplify command that asks the agent to simplify code within a selected Git change scope, including staged changes, commits, and untracked files.

An in-page pet for DSH Web with multi-session task notifications and controls to open tasks, stop turns, and respond to supported approval and question requests.

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.

Adds /pua to steer the agent to try another approach and verify results before claiming completion, with 15 company styles, persona modes, global and per-conversation settings, and an optional loop that continues until a verification command passes, the iteration limit is reached, or the user cancels.

Connect IM bots to DeepSeek Harness via QR codes or bot credentials (9 channels: Feishu, WeChat, DingTalk, WeCom, QQ, Slack, Telegram, Discord, and WhatsApp).

Hindsight, agent memory that learns: long-term project memory with auto recall and retain, knowledge pages, deep reflection, and per-repo memory banks.

Give DeepSeek Harness a real office environment. Univer Office Plugin brings spreadsheets, docs, slides, canvases, relational tables, and more into one runtime — with connected data, validation, versioned changes, and isolated worktrees for multi-agent collaboration.

AgentTeams multi-agent teams.

Claude Code-style full-screen terminal UI: pixel-whale header, live status line, and streaming thought expansion.

Cross-agent, local-first persistent memory plugin for DeepSeek Harness (DSH), powered by Mnemon. It shares long-term memory across Mnemon-enabled agents and adds runtime memory, searchable project documents, semantic recall, knowledge graph, and a Sidebar UI.

Requires DeepSeek Harness 0.1.5-rc.1+ (DSH Desktop >= 2.0.7) and dsh-better-sidebar >= 0.19.0 - update both before installing or updating this plugin. Plays local Wallpaper Engine Video/Web wallpapers behind the chat, renders Scene wallpapers as extracted static frames, and adds content-rating/type filters, custom uploads and an iOS-style liquid-glass settings window.

Free, keyless web search for DSH: 7 engines (DuckDuckGo/Bing/SearXNG free + Exa/Perplexity/DeepSeek paid), auto-failover, settings-page UI with API key inputs and official links, web_fetch, and an engine test tool.

Desktop pet for the DSH Web UI with 25 transparent animations, screen wandering, click reactions and drag, plus a reproducible asset-generation pipeline.

Web search bridge for text-only agents: ask the web or X, get structured JSON evidence (search, fetch, citations).

OpenViking memory and context bundle for DeepSeek Harness: pre-step auto-recall and profile injection, session capture, `viking://` URI guarding, and recall/write memory tools backed by an OpenViking server.

Whale-girl skin series for the DSH Web UI (maid-atelier).

Local-first code knowledge graph for coding agents: 10 MCP tools for layered context compression, DAG planning, incremental AST indexing, a cross-session skill flywheel, diagnostics, and graph artifact import/export.

One-command skin plugin: 8 original themes, translucent wallpaper with opacity/blur, per-user accent, and shareable theme-pack import/export, favorites and surprise-me — purely native on DSH's token system.

Free vision for text-only agents: built-in keyless vision chain plus pixel tools (Q&A, grounding, crop, pixel diff, colors, OCR, SVG trace, cutout, screenshots); paste an image to use it.

Interactive UI components rendered inline in replies: layout, charts, forms, quizzes, mermaid, 3D scenes, and an action event loop back to the model.

DeepSeek Harness bundle registering one skill that turns long-form production (academic papers, industry analysis, business commentary) into a 9-role pipeline: T1 literature / T2 data / T3 case scouts running in parallel, T4 analyst, T5 writer, T6 critical companion, T7 auditor, T8 finalizer run by the coordinator, T9 peer reviewer — across 6 phases with triangular evidence verification, a 23-check M-gate, a G0-G14 audit including a Chinese AI-trace gate, peer-review scoring with journal matching, and 4 human checkpoints. Installs with `dsh plugin add lunheng-article-pipeline` (package.json#dsh.bundle.patch plus a lib/index.js entry that registers the skill); ships role cards for T1-T9, templates and 11 zero-dependency verification scripts, with five-language READMEs.

Plugin governance: new/updated plugins stage in a candidate area first, then hot-mount after startup — success promotes, failure auto-disables, repeated failures freeze, one-click safe mode, sidebar diagnostics panel (npm: `dsh-my-guardian`).

Generate validated, self-contained interactive architecture, workflow, sequence, data-flow, and lifecycle diagrams from repositories or system descriptions.

White-box AGI architecture exploration: metacognition (self-cognition loop), continual learning (knowledge flywheel), world model (condition space, spatiotemporal memory graph), self-improvement (bootstrap discipline), zero-LLM white-box pipeline, and auditable trust guardrails.

Find plugins without leaving the agent: search this curated registry by keyword or category, with ready-to-run install commands.

In-place conversation rewind in the same session window without forking (Claude Code /rewind semantics): a per-message ↶ button cuts the model context back to any user message, with an optional Claude-Code-style file restore from disk-persisted before-backups.

BrowserSkill bridge for controlling visible Chrome and Edge Agent Windows from DeepSeek Harness, with native browser tools, accessibility and VOM observations, screenshots, owned multi-session control, and a live Web UI overlay.

Native conversational image generation for DeepSeek Harness: ask the agent to create an image, and it handles generation and keeps the result directly in the conversation.

Memory-assembly team for DeepSeek Harness: every message triggers a five-step cognition loop (judge, retrieve, assemble, feedback, calibrate) carried by role-playing subagents (judge, retriever, archivist, advocate, editor, scribe), using BM25 retrieval, time-ordered material, and LLM assembly to build useful material packs injected into linghun. Works with dsh-linghun.

Adds drag-and-drop attachments for local files, folders, ZIP archives and Office documents.

Adds a native sidebar menu item in DSH that opens chat.deepseek.com in a standalone browser window with persistent login, and supports bidirectional text selection transfer between DSH and the web page.

Interactive terminal UI for DeepSeek Harness: tables, Mermaid and chart rendering, side conversations, and the same Cordis plugin model as dsh Web.

MCP management panel for the DSH web UI: per-server status, transport and full tool input schema, with add/edit/enable/disable/remove in global and project scopes, reconnect for global servers, a five-server built-in catalog, and config import from ten other clients with a preview. A project's MCP servers share one connection per (project, serverName) — the first session opens it and the last one closes it — so concurrent sessions reuse a single mcp-client instance; the panel shows how many sessions share it and marks a config change as pending until the connection is rebuilt.

Local-first DSH Web work checklist with rich-text notes, categories, folding, drag reordering, search, JSON import/export, and a restorable trash.

Adds text selection annotation tools and annotation chips to the dsh web composer.

Zhipu coding-plan sign-in, quota, usage and reset panel for DeepSeek Harness.

DeepSeek account wallet balance and the current peak or off-peak billing period, in a fixed status region at the sidebar foot, with a manual refresh and an official top-up link.

A token-based DeepSeek Harness theme plugin with ten presets, custom colors, and system font pickers.

Unofficial Gemini Cloud Code Assist OAuth integration with isolated account storage; carries account-ban risk.

Adds a model route where a Lead plans and reviews while a Sidekick performs code changes.

Adds subscription OAuth and provider Plan API-key logins through Pi adapters, using a DSH-owned credential store.

Edit reasoning effort levels and thinking formats for models that declare none.

Relays the ZCode CLI (the client-bundled coding agent) into DeepSeek Harness as a model provider: a resident app-server session injects the Start Plan account and signs each request with the OAuth plan token, so model requests burn ZCode Start Plan / Coding Plan quota directly — real streaming, image input, per-session resume, no API key.

Uses a dedicated model for context compaction rescue and adds manual compaction to the native context popup.

Imports local coding-agent session histories so work can continue in DSH.

Delete one finished turn from a DSH conversation without deleting the session — the trash button next to the last assistant reply removes the question, that reply and the tool records of the turn from the conversation surface and from the model context, while the session id, title, later turns and the append-only log stay; the removal is written as a persistent tombstone, so it survives a reload.

Personal paste inbox for DeepSeek Harness (dsh): /inbox in the composer or the sidebar panel files links, images, text and credentials into a local vault, classifies them by local rules and then by a rate-capped model pass, and browses, searches and edits them from the panel; the assistant retrieves records on request in conversation, credential bodies stay encrypted at rest, and an optional WebDAV or S3 remote syncs records and attachment bytes. Windows only so far.

macOS computer-use tools backed by a plugin-owned Cua Driver runtime.

Correct-encoding command runner and mojibake recovery: encoding_run spawns a child process and decodes its raw output bytes (UTF-8/UTF-16LE/GBK auto-detected or forced), and encoding_decode recovers garbled text back to correct Unicode.

Delegates self-contained coding subtasks to the local Claude Code subscription through the official Agent SDK and returns the result to the host session. Nineteen per-call parameters control model, thinking effort, permission mode, allowed tools, turn count and budget cap; background jobs return a jobId immediately and stream incremental output; the result carries a session handle that can be passed back as resume to continue the same conversation; commands expected to run past ~20 seconds go through the built-in mcp__dsh__shell channel, which streams output line by line without consuming model context; a Claude Code monitor panel in the session lists jobs, renders the structured process, shows live output blocks and cancels a run; the delegation procedure ships as a runtime-registered skill, so installing the plugin installs the skill.

Run a read-only Dameng DM8 database inspection with 85 checks and produce an HTML report.

Manage DeepSeek account balance and usage from the DSH web interface.
