Every DeepSeek Harness plugin

What it is — Integrates multiple MCP servers for DeepSeek Harness.

Who it is for — When building an agent in DeepSeek Harness that needs file read/write, Git operations or browser automation, this plugin supplies the corresponding MCP tools. Users who need to manually manage each MCP server's startup parameters do not need this plugin.

Watch out — Sandbox testing passed: installed in a fresh profile and registered with harness. No obvious issues found.

The verdict — I would install it because it guarantees connectivity verification for each server through CI checks.

What it is — Automatically records runtime facts including tasks, models, tools and failures into a human-readable journal at DSH session end.

Who it is for — Developers using DSH in headless profile who require recording runtime facts for analysis should install this plugin. Users focused solely on solution generation or agent memory management without needing fact observation may find it unnecessary.

Watch out — From source install, manually allow build script to run. Sandbox test passed in new profile with no obvious issues.

The verdict — I would install it because it provides complete session fact logging for post-run analysis.

What it is — DeepSeek Harness plugin that teaches while coding with concrete scenario-grounded explanations, Socratic guidance, and TODO(你) practice blanks.

Who it is for — Developers using DeepSeek Harness for complex coding tasks who want to learn principles can install this. Those seeking only quick results without process details can skip it.

Watch out — Manual permission for build script is required when installing from source. Sandbox test passed with registration in new profile. No obvious issues found.

The verdict — I would install it for the guidance during coding; however, if the goal is just to get the task done fast, direct mode suffices.

What it is — dsh-ding notifies you when the conversation finishes by playing a sound and showing a Windows notification.

Who it is for — When you use DeepSeek Harness to handle agent tasks that require attention after completion, it is suitable to install in your profile. Users who only view conversations in the browser without needing notifications do not need to install it.

Watch out — Manual approval of the build script is required when installing from source. Sandbox test passed with no obvious issues found.

The verdict — I would install it because it provides notifications when the agent returns to idle state.

What it is — This is an isolated child-process reverse proxy for LAN mobile access to DeepSeek Harness Web UI, supporting first-visit approval, per-device token binding, rate limiting, and injection of compact mobile layout with randomUUID polyfill.

Who it is for — It is suitable to install this plugin for users in a local area network who want their mobile devices to securely access the Web UI and use compact layout. Users not using local area network access do not need to install it, because they do not need to handle mobile device approval and layout injection.

Watch out — Sandbox testing succeeded in a fresh profile and registered it into the harness profile. No obvious issues were found, but it requires a trusted local area network due to lacking independent authentication. Static analysis indicates execution of shell commands.

The verdict — I would install it because it isolates the main service via child process and binds per-device tokens, provided the user is in the same local area network and needs mobile secure access with layout optimization.

What it is — dsh-expert-mode is a DeepSeek Harness agent preset that includes a chief coordinator and 11 domain-expert subagents supporting automatic task delegation.

Who it is for — When tasks in DeepSeek Harness require covering multiple professional domains such as data processing, legal risks, and product planning, this preset can serve as chief coordinator for automatic delegation to expert subagents. If a user prefers to maintain multiple independent prompt and tool setups themselves, they would not need this preset.

Watch out — Sandbox testing passed: installation in a fresh profile succeeded and it was registered into the profile. It will execute shell commands. No other obvious issues found.

The verdict — I would install it because this preset adds an expert delegation layer in DeepSeek Harness, with the premise that tasks span multiple professional domains.

What it is — The dsh-update-checker plugin automatically checks for updates to DeepSeek Harness and installed third-party plugins from npm, displays a locale-aware banner in the GUI, and offers one-click updates with a restart watchdog.

Who it is for — If you run the DeepSeek Harness web GUI and need to manage third-party plugin versions, you can install this plugin. It scans installed plugins against npm versions and shows update prompts in the banner. If you only use official plugins and do not need to manage third-party updates, you can skip it.

Watch out — After installation in a fresh profile, it registers with Harness. It executes shell commands as per static checks. No obvious issues found.

The verdict — I would install it because it provides full update lifecycle including rollback and restart monitoring.

What it is — DeepSeek Harness Computer Use plugin adds cross-platform virtual mouse human-like operation with 11 tools including screen_observe, computer_click, computer_type.

Who it is for — When needing to simulate human-like desktop operations for specific tasks using DeepSeek Harness with AX-tree mode, it fits. Users without desktop operation needs can skip it.

Watch out — Sandbox test passed after registration in fresh profile. Shell command execution is a static check note. Safety includes snapshot TTL, app whitelist and dangerous-action approval. Vision fallback requires ZHIPU_API_KEY and auto-degrades to GLM-4V-Flash when AX tree empty, but Windows/Linux untested on real hardware, visual reading imprecise on macOS calculator windows not in AX tree.

The verdict — Would install if already have harness-desktop and cua-driver authorized, since it extends desktop operation capabilities, but skip if no desktop operation needs or frequent vision fallback required.

What it is — DeepSeek Harness voice input plugin supports speaking into the microphone and submitting recognized text as a normal chat message via local or browser speech recognition.

Who it is for — If using DeepSeek Harness for conversations where quick input is needed, you can install it. If using DeepSeek Harness for pure keyboard input, you need not install it because they may have other input methods available.

Watch out — 实测通过，在全新 profile 中安装并被 harness 注册进 profile。没发现明显的坑。

The verdict — If I need microphone input for chatting, I would install it because it provides an alternative input method without affecting the persona.

What it is — DeepSeek Harness composer plugin adds expand/collapse button in the tool row to switch long drafts to 70vh writing view.

Who it is for — When writing long drafts in DeepSeek Harness composer, this plugin allows switching to 70vh tall view. Users preferring the default small height can continue without this plugin, as it optimizes for longer content.

Watch out — Sandbox test passed: successfully installed in a new profile and registered with harness. No obvious issues found.

The verdict — I would install it because the state is persisted via localStorage ensuring it survives page refreshes.

What it is — Adds a one-click restart button to the sidebar footer of the DSH Web UI, which restarts the dsh web process and persists across restarts.

Who it is for — Users of the DSH Web UI in a web profile who need to quickly restart the harness process can use this plugin. Users who do not run the DSH Web UI or do not require process restarts may find it unnecessary.

Watch out — Tested successfully in a fresh profile, registered by harness. Compatible with DeepSeek Harness 0.1.0-rc.6 web profile. Requires manual approval of build scripts when installing from source.

The verdict — Install it if you manage the DSH web process frequently in the web profile, as it provides reliable restart functionality verified through testing.
