Every DeepSeek Harness plugin

What it is — Generates structured comparison and unified diffs for text, JSON, CSV and Markdown.

Who it is for — When an agent needs to compare two pieces of content, this plugin is suitable to install. If you use system diff tools, you can skip this plugin.

Watch out — Static check indicates it will execute shell commands. Sandbox test passed: installed in a new profile and registered by harness. No obvious pitfalls found.

The verdict — I would install it because it is zero-dependency with pure functions.

What it is — Provides a zero-dependency RFC 4180 CSV state-machine parser.

Who it is for — When your DeepSeek Harness agent session involves tabular data from exported files, API responses, or report snippets and you want to avoid spawning bash processes or having the model write parsing scripts. If your agent session does not involve tabular data, you do not need this plugin.

Watch out — Sandbox test passed: installed in a fresh profile and registered into the profile by harness. No obvious pitfalls found.

The verdict — I would install it because it provides a deterministic processing scheme that returns structured JSON via a single function call.

What it is — Provides Qwen-MM multi-modal capabilities as a DeepSeek Harness plugin bundle.

Who it is for — When using Qwen models in DeepSeek Harness and needing multi-modal capabilities, this plugin can be installed. If Qwen-MM capabilities have already been directly integrated into the configuration file, there is no need to install this plugin again.

Watch out — Sandbox test shows it can be installed but the build script is blocked. When installing from source, the build script must be manually allowed first. No other obvious issues found.

The verdict — I would install it because it supports enabling Qwen-MM capabilities in DeepSeek Harness, but an extra manual step is required to allow the build script.

What it is — dsh-net-proxy routes DeepSeek Harness agent's network requests through local HTTP/CONNECT/SOCKS5 proxies.

Who it is for — When using DeepSeek Harness to perform tasks such as web_search that require external network access, this plugin enables local proxy configuration. Users who use DeepSeek Harness for tasks not involving external network requests can skip this plugin.

Watch out — Sandbox test passed: installed and registered in new profile. Static check flags shell command execution and need for API key or token. No other runtime issues found.

The verdict — I would install it because it routes agent network requests through local proxy, sandbox test passed, but with premise of having a local proxy server and accepting the static check flags.

What it is — Community plugin store for DeepSeek Harness Web UI.

Who it is for — When installing community plugins in DeepSeek Harness Web UI, this store is suitable. Users who do not use DeepSeek Harness Web UI need not install it.

What it is — dsh-pets plugin integrates Codex Pets-style floating pixel pet into DeepSeek Harness web GUI, with 10 Petdex-compatible pets, 9-state animations, draggable overlay, and pet_say tool.

Who it is for — When running long AI coding agent tasks in the DSH web profile, the pet's behavior provides visual indication of agent states like thinking, waiting, or review. Users who only use text logs or CLI for agent monitoring do not need this plugin.

Watch out — Sandbox test passed with registration in fresh profile. No obvious issues found.

The verdict — I would install it because the pet_say tool lets the agent speak through the pet for better interaction during tasks.

What it is — Adds dedicated model routes and tools for vision understanding, image handoff, context compaction, approval model, subagent model, title model and image generation to DeepSeek Harness.

Who it is for — When handling image analysis or subagent tasks, this plugin is suitable for installation. If conversations are purely text-based and involve no tool or image needs, this plugin is not applicable.

The verdict — I would install it because it provides structured trajectory views and anomaly detection for long-running agent tasks, but I need to manually allow the build script during source installation.

What it is — dsh-island bridges DSH sessions, tool calls, and approvals to the macOS menu bar notch panel over a Unix socket, with in-panel allow/deny.

Who it is for — When running DSH agents on macOS and needing to monitor sessions and tool calls in the menu bar, this plugin is suitable to install. If not using macOS desktop or not requiring panel-based approval handling, this plugin is not needed.

Watch out — Installation from GitHub source requires manually allowing the build script. Sandbox testing passed: installed in a fresh profile and registered by harness. No obvious issues found.

The verdict — I would install it if I need direct in-panel handling of tool calls and approvals on macOS, because it uses zero-intrusion side-channel listening.

What it is — Intercepts and audits every tool call from DeepSeek Harness agents, requiring human confirmation on sensitive operations.

Who it is for — When DeepSeek Harness agents execute shell commands or file operations, this plugin is suitable to install. If the agent only performs operations within known safe directories, you can skip installing it.

Watch out — Sandbox test passed. Installed in a new profile and registered by harness. Requires providing an API key or token. No obvious pitfalls found.

The verdict — I would install it because it provides runtime security auditing and human confirmation for tool calls, but only if the agent frequently performs sensitive operations.

What it is — This is a skin plugin for DSH Web UI, supporting built-in skins and custom image skins.

Who it is for — If you want to customize skin for the DSH Web UI, this plugin is suitable for installation. Users without a DSH web profile or without pnpm in their environment may not need to install it.

Watch out — The sandbox test passed: installation and registration succeeded in a fresh profile. Custom skin images are processed locally without uploading to any server. No obvious issues were found.

The verdict — Installing this plugin is appropriate because it is a pure client plugin that does not modify any DSH source code and the sandbox test passed.

What it is — Provides audit reports for DeepSeek Harness sessions, covering steps, tool calls, failures, and token usage.

Who it is for — When using DeepSeek Harness for tasks involving steps and tool calls, you need to analyze repeated actions, failure rates, and token usage. For users who only want to view the raw session logs, this plugin is not needed.

Watch out — Sandbox test passed, installation and registration succeeded in a fresh profile. No obvious issues found.

The verdict — I would install it because it states facts and deterministic findings without efficiency scoring and leaves judgment to you.

What it is — dsh-testgen provides a /testgen command and generate_tests tool for automated unit-test generation, running, and fixing inside DeepSeek Harness.

Who it is for — Developers who use DeepSeek Harness plugins to write code and need an integrated tool for generating, running, and fixing unit tests are suitable for installing it. If you prefer to handle all test generation and execution entirely outside the harness, you do not need to install it.

Watch out — Sandbox testing shows it installs but the build script is blocked by pnpm and requires manual permission for github:bujue600-arch/dsh-testgen to complete registration. No obvious pitfalls were found.

The verdict — I would install it because it closes the test generation-running-fixing loop inside the harness, but I would first need to manually allow the build script, otherwise registration fails.
