dsh-linalg: DeepSeek Harness Linear Algebra Toolbox
dsh-linalg is a linear algebra toolbox for DeepSeek Harness, designed to address numerical errors that arise in large-model operations such as matrix multiplication and determinant computation. The plugin provides zero-dependency local exact arithmetic and supports capabilities such as matrix operations, solving linear systems, eigenvalue decomposition, and vector operations. After installation, users can configure the matrix dimension and the number of decimal places to retain via a configuration file. The plugin employs algorithms such as Gaussian elimination and the cyclic Jacobi method, using tolerance settings to ensure stable results.
Read Moredsh-complex: DeepSeek Harness Complex Number Math Toolkit
`dsh-complex` is a complex-number computation plugin for DeepSeek Harness (DSH), aimed at addressing the low accuracy of complex-number arithmetic in large models. It uses a zero-dependency, deterministic computation design and provides six core tools: parsing, arithmetic, coordinate conversion, function evaluation, square roots, and quadratic equation solving. It supports IEEE double-precision floating-point computation, follows CPython library conventions, and handles invalid inputs by returning `valid: false`. It can be installed via the `dsh plugin` command for use in scenarios such as signal processing and control theory.

Read MoreDSH Message Body Display Layer Text Replacement Plugin: Meow Speech
The DeepSeek Harness plugin `tumi-huakai/dsh-plugin-meow-speech` allows users to replace text display in the browser rendering layer of conversations (e.g., replacing “I” with “this kitty”) without modifying the underlying real conversation data. It provides preset rules such as “I → this kitty” and “you → master,” supports whole-word matching, code block protection, and streaming output adaptation. Users can configure rules via a floating button in the bottom-right corner, and the settings are stored locally. The plugin only affects the main body of AI replies and user message bubbles, making it suitable for adjusting the display style of the conversation interface without changing the underlying logic.

Currently, it must be installed by cloning from source, making it suitable for developers who want to improve the visual expressiveness of agents at low cost.
Read Moredsh-auto-reconnect: DSH Web Client Disconnection and Zombie Connection Fix Plugin
The official connection controller in DeepSeek Harness is prone to infinite loops and has a “zombie connection” blind spot. The dsh-auto-reconnect plugin monitors browser visibility and focus events to automatically recover from terminal disconnections and silent drops. It runs entirely on the client side, requires no build step, and does not modify the official package, while allowing reconnection policies and logs to be adjusted via localStorage. Installation requires a process restart; compatibility with specific versions has been verified, and the plugin aims to improve connection stability in networked environments.
Read Moredsh-undo: A DSH Session Rewind and Re-edit Tool
`dsh-undo` is a plugin that adds undo functionality to DSH sessions, addressing the pain point of being unable to revert edits. Based on the Cordis paradigm, it uses a “forking” mechanism to allow developers to go back to any historical prompt and re-edit it. The plugin provides two interaction patterns: a dropdown menu in the session header and a left-side ruler; clicking either creates a child session and pre-fills the text. Note that the original session remains unchanged, and only the conversation state is restored; external side effects are not undone.
Read MoreDeepSeek Harness Site Controller: Unified Management of Web Service Lifecycle and SSH Deployment
`dsh-wei-sitecontrol` is a site controller plugin for DeepSeek Harness, designed to address the registration of multiple web sites and HTTP services, Git operations, and remote deployment over SSH.

Read Moredsh-chat-fold: Compact Long-Chat Folding and History Window Expansion for DeepSeek Harness Web
`dsh-chat-fold` is an unofficial plugin for DeepSeek Harness Web, designed to address issues in long sessions where the default folding feature fails and the history window is too small. It provides a compact folding mechanism that hides settled turns under the `Ran for…` collapsible, keeping the interface tidy, while expanding the default history window from 50 to 250 entries. The plugin detects streaming state and only intervenes when stock folding is unavailable. Note that the plugin relies on specific DOM anchors, and state is stored in memory only.
Read Moredsh-presets-hidden: DeepSeek Harness Browser-Side Preset Display and Sorting Plugin
The DeepSeek Harness plugin dsh-presets-hidden is designed to address the visual clutter caused by the official preset selector when many custom presets are present. By taking over the rendering logic on the browser side, it provides refined search, show/hide filtering, toggles, and sorting controls under "Settings -> Preset Display," with support for persistent configuration and data migration. It improves preset management efficiency, enabling developers to focus more on implementing Agent logic.
Read Morei-am-yuike: Catgirl Yuike Character Plugin
The i-am-yuike plugin is designed specifically for DeepSeek Harness (DSH) to enable the persona to fully take over the system prompt, remove redundant framework information, and deliver a pure role-playing experience. It is configured to ensure that the persona drives the identity and style, and it disables toolchains such as `skill-filesystem` and `tool-skill` to keep the conversation clean while retaining core development capabilities. After installation, select the `yuike` preset to enable it. Usage note: to prevent persona collapse, it is recommended to run one non-thinking conversation turn before enabling thinking mode in order to establish context. The plugin supports DSH 0.1.6 and later, and the source code is available on GitHub.
Read Moredsh-tool-guard: DeepSeek Harness Global Tool Blocking and Protection Plugin
dsh-tool-guard is a preset-agnostic global tool-blocking plugin for uniformly controlling tool visibility and invocation permissions on the host plane. It implements interception through a three-layer mechanism (presentation-layer filtering, execution-layer hard denial, and a self-protection gate) and provides a WebUI editor with hot-reload configuration support. The plugin is not bound to any specific preset, and core tools (such as read, write, edit, and bash) are protected by the self-protection gate and cannot be blocked. During installation, the repository must be linked into the DSH web profile bundle, supporting either global mounting or scoped mounting.
