Plugins

Skills & MCP panel for the DeepSeek Harness Web GUI: list, search, inspect and hot-toggle skills and MCP servers from Settings.

Multi-threaded downloader plugin for DeepSeek Harness: bundles aria2, probes file size and picks aria2 multi-connection or curl fallback automatically (Windows x64/arm64, Linux x64/arm64)

Jev (TypeSafe System One) gives the human a second opinion, not the agent. When DSH's model asks you a multiple-choice question, dsh-jev-advisor builds a structured Jev request and floats the recommendation, probability spread and confidence beside the op

Third-party DeepSeek Harness brand plugin: whale mark plus a minimal 'deepseek' wordmark for the Web client sidebar.

Universal MCP Apps Host & UI Plugin for DeepSeek Harness (DSH)

Free OpenCode Zen models in DeepSeek Harness through native HTTP requests. No OpenCode installation, login, API key, server, container, or LiteLLM is required.

自建 DSH 浏览器服务：一个包 = 单例 CDP 守护进程 + 33 个 browser_* 工具面 + DSH ctx.browser provider（一个 dsh plugin add 装完即用）

A structured decision layer for the DeepSeek Harness agent loop: a danger-call gate, output self-check, tool narrowing, and loop guard backed by a pluggable adjudication model.

Progressive long-term memory for DSH: sharded markdown bodies under ~/.dsh/memory/topics/, with only a live-generated index (shard · count · path · per-entry line numbers) injected into the system prompt — so the prompt cost stays flat however large the m

Session sync settings plugin for the dsh web GUI: the Sync section page with git remote, cadence, project mappings, and manual sync, talking to the host through the plugin's own same-origin HTTP API

A theme gallery for DeepSeek Harness (DSH): JSON-defined skins with full-screen coverage and sidebar scenery, a 15-swatch palette-picker card, a pet-widget card (7 registry-driven pets playing by the chat input), a mood-greeting card (a scrolling greeting

Unified @ mentions in the DeepSeek Harness web composer: five built-in categories (file, folder, skill, past chat, plugin) plus a data-source seam any plugin can register through, references to absolute paths outside the workspace, and a candidate menu that can be scoped by a folder named earlier in the draft and pages with PageUp/PageDown instead of hiding rows.

Local TXT reader in a right-sidebar tab plus a spoiler-safe AI reading companion: the model only sees what you have already read — the current chapter, the tail of the previous chapter, and a per-book background file it grows as you go. Excerpts, thoughts and the companion replies become structured Markdown notes exportable to Obsidian; raw text unlocks only for a book you mark as finished.

Adds standard Unicode emoji to dsh replies at the point that best matches the content, and keeps emoji out of any sentence that already carries a kaomoji.

Settings-UI editor that assigns per-teammate model and reasoning-effort rules for DSH native agent teams, resolved at spawn time by wrapping SubagentRuntime.startContinuable. No official files are modified.

Theme studio for the DeepSeek Harness web GUI: eight switchable preset styles, accent and panel-translucency fine-tuning, host-side wallpapers painted on the first frame, and a one-click fix when the wallpaper-engine glass tint greys out light styles.

DeepSeek API balance badge in the sidebar footer beside Settings — reads the key DSH already stores, shows granted/topped-up breakdown on hover, flags a balance under ¥2, and refreshes every 60 seconds or on click.

A newspaper-style front page for a session you left running, as a Conversation View tab beside Chat and Trajectory: a per-turn timeline (duration, steps, tools, tokens, outcome), file churn counted per file, where the wall clock went and how much of it was the model rather than tools, which single turn ate the spend, failures nobody retried quoted with their failing command, and a context-pressure gauge measured against the routed model's own declared capacity. The briefing is folded from the durable session log and never generated by a model, so it costs no tokens, cannot hallucinate, and is byte-identical for the same log and clock; it appends nothing to the session and reaches no model, and it reports a pending approval without ever answering it. Pages are offered only when they have content, and the tab refreshes itself on turn settle and on a two-speed poll backed by a metadata-only tail probe.

Pins workspaces holding a running session to the top of the sidebar session list, and draws the running session row with an accent frame and tinted title, plus a short settle animation when a session stops running. Colours come from the active theme's own tokens, with the running accent taken from the token the status dot paints ongoing with.

Paper library and reading workbench: arXiv search, a local plain-file library (metadata / PDF / extracted full text), and three-level reading notes (overview / understanding / critique) kept as markdown beside the PDFs; seven model tools plus a web panel.

Fireworks celebration engine: floats fireworks above the chat window while the agent codes — welcome show, per-turn salutes, tool sparks, milestone celebrations, a finish finale and a dud on failure; each event type has its own fireworks card group with random variants, and token usage decides firework size, height and splendour.

Matrix digital rain: drapes the chat window in the classic green character rain — cascading columns with incandescent white heads and green tails, streaming the tokens the agent is generating into the rain in real time; opacity, speed, density, font size and colors are all adjustable, and rain intensity follows agent activity.

Gemini provider for DeepSeek Harness on Google Cloud Vertex AI, with Application Default Credentials, streaming, and thought-signature replay across tool calls.

Execution flow chart: renders the current session's execution as a vertical node flow (turns, user, assistant, tools, approvals, retries, compaction), appended in real time over SSE with auto-follow scrolling — the chart draws wherever the session executes.
