Every DeepSeek Harness plugin

What it is — Integrates microsandbox microVM backend support

Who it is for — When needing microsandbox_exec or microsandbox_fs tools in the DeepSeek Harness, this plugin can be used. Users on macOS Apple Silicon do not need to install it because macOS Apple Silicon real-host acceptance is not included in the first release.

Watch out — Installation from source requires manually allowing its build script. Tests show this step is required for registration completion. No other obvious issues found.

The verdict — I would install it if needing microsandbox_exec or microsandbox_fs tools, because it provides fail-closed microVM capability, but from source install requires manually allowing its build script.

What it is — JSON Schema validation plugin offering pure functions for data validation, path localization, schema explanation, and default application.

Who it is for — Agent needs to validate JSON data for API responses or plugin manifests. Developers with built-in verification can opt for alternative methods.

Watch out — Sandbox test passed with successful registration in a new profile. No obvious issues detected.

The verdict — I would install it as it provides an independent pure function verification kernel for reliable schema validation.

What it is — Provides regex tool to DeepSeek Harness for testing, extraction, replacement and static explanation.

Who it is for — When using a model in DeepSeek Harness to verify user-provided regex patterns, extract fields from text logs and perform safe replacements, this plugin applies. It is not necessary if the model primarily handles structured data analysis.

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

The verdict — I would install it because its static parsing capability provides direct value in model pattern verification scenarios.

What it is — DSH plugin registers JSON query tool supporting JMESPath subset path queries.

Who it is for — When DSH Agent processes JSON data, if structural path query is needed, this plugin is suitable. If you only need string-level search, this plugin is not needed.

Watch out — Sandbox test passed, installed in fresh profile and registered into harness. No obvious issues found.

The verdict — I would install it because it provides read-only JSON querying capability.

What it is — DSH plugin providing base64/url/hex encoding, hash and UUID generation.

Who it is for — Suitable for Agent scenarios handling encoding and hashing in DeepSeek Harness. Users in monorepo integration may find it unsuitable as an independent bundle.

Watch out — Sandbox test passed: installed in new profile and registered by harness. Will execute shell commands but not a defect. No obvious issues found.

The verdict — I will install it because it is zero-dependency pure functions and passed sandbox test.

What it is — Add a simplified auto-chess game to the DSH sidebar, supporting human vs AI or AI vs AI.

Who it is for — If you want to experience AI-assisted strategy games in the DSH web sidebar, such as playing chess against AI or watching AI battles. Users who prefer standalone local game software don't need this plugin.

Watch out — Sandbox test shows installation is possible but the build script is blocked by pnpm, requiring manual approval for the build to complete registration. Users need to manually allow the build script to install successfully. No other obvious issues found.

The verdict — I would install it because it offers a unique browser-based AI strategy simulation, but must manually allow the build script during source installation.

What it is — DSH plugin providing local image OCR and understanding via macOS Vision.

Who it is for — Developers working on macOS who need to process image inputs with OCR or scene description using DeepSeek Harness should install this plugin. Users not running macOS 11+ can skip this plugin.

Watch out — Sandbox testing passed in a fresh profile with successful registration. First run requires compilation taking about 5 to 10 seconds then caching. Requires macOS 11+ and Xcode Command Line Tools.

The verdict — I would install it because it provides fully local image understanding on macOS, but only if running on macOS 11+ with Xcode Command Line Tools.

What it is — dsh-honcho-sync is a bridge plugin connecting DeepSeek Harness (DSH) to Honcho memory service. After installation, DSH automatically syncs every conversation turn to a self-hosted Honcho service and provides the AI with tools for recall, search, and remember across sessions.

Who it is for — If you are developing an agent in a DSH profile that requires persistent memory across sessions and have already deployed a Honcho service, this plugin can automatically sync conversations and inject context.

Users who do not need cross-session persistent memory and rely only on information within the current session do not need to install it.

Watch out — A self-hosted Honcho service must be deployed first (one Docker command). Sandbox testing passed: installed in a fresh profile and registered into the profile by harness. Configuration is done graphically through DSH settings panel without editing YAML.

The verdict — I would install it because it adds cross-session memory tools to DSH, but only if I can deploy Honcho myself; not worth it for tasks that only require a single session.

What it is — Integrates DeepSeek Harness with local Obsidian vault using obsidian_* tools to support note search, read, write, move, and trash.

Who it is for — When DeepSeek Harness agent needs local note handling, this plugin fits. If only cloud-based knowledge operations are needed, not suitable for this plugin.

Watch out — Passed sandbox test after installing in a new profile and being registered by harness. No issues found in static checks.

The verdict — I would install it because it allows direct local vault access without servers.

What it is — Adds a QR-code button above the Settings button in the DeepSeek Harness sidebar footer, enabling phones to connect to the web UI via an auth-gated reverse proxy.

Who it is for — If you need to scan a QR code with your phone to connect to the DeepSeek Harness web UI on local network or internet, this is suitable. If you primarily use the desktop browser for DeepSeek Harness without needing phone cross-device access, this plugin may not fit your scenario.

Watch out — Successfully tested by installing on a new profile and registering into the profile with Harness. Static check indicates it will execute shell commands. No other obvious issues found.

The verdict — I would install it because it simplifies phone access in specific network settings, but the premise is trusting the network and using short session lengths.

What it is — Provides native browser tools for DeepSeek Harness, enabling per-agent isolated sessions, bounded snapshots, ref-based interactions, screenshots, and safe routing.

Who it is for — When an Agent needs to perform web navigation and data extraction via model calls, this plugin is suitable; pure-text Agents without web interaction needs do not require it.

Watch out — Tested successfully in a fresh profile where the plugin registers correctly. Agents complete Wikipedia browsing, search, and screenshot in about 15 seconds. It executes shell commands and may download a 200 MB Chromium cache on first use.

The verdict — I would install it because it allows Agents to safely route tasks to a browser using native tools.

What it is — PaperLab is a LaTeX paper workbench that supports annotating any text in PDF and lets a dsh agent revise sources with compile checks and git history.

Who it is for — Users who write and iterate on LaTeX papers in the DeepSeek Harness environment and require dsh agent assistance for revisions, compile verification, and git management would find PaperLab suitable. Users who do not rely on DeepSeek Harness plugin system or git version control for their projects would have no need for this tool.

Watch out — Sandbox testing passed with installation in a fresh profile and registration into harness profile. No obvious defects were found. The plugin executes shell commands, so manual permission may be needed for build scripts.

The verdict — I would install it to integrate PDF annotation-based revisions with DeepSeek Harness agent loops, as it provides compile checks and git history management for LaTeX papers.

What it is — Provides per-call cwd support for subagents in DeepSeek Harness by extending dsh-subagent-tools and including the two required provider patches.

Who it is for — When you need to control cwd per subagent call, this plugin is suitable. If you need subagent tools but not cwd control, you can use dsh-subagent-tools.

Watch out — Sandbox test passed: installed successfully in a new profile and registered by harness. Requires manual application of the two provider patches for foreground and background paths. Web sessions also require running the preset adapter.

The verdict — I would install it because it fixes cwd being silently ignored in the background in-process path, but you must manually apply the patches.

What it is — dsh-messager tracks session states in the DSH web app and sends alerts for interactions, task completions, and errors via system toasts, browser notifications, and services including Feishu, WeCom, Discord, DingTalk, and Telegram.

Who it is for — When you are handling interactive tasks or multi-turn dialogues in the DeepSeek Harness web interface and require alerts for pending interactions or completed tasks, this plugin fits your needs. If you only interact with DeepSeek Harness through the command line without the web UI, you do not need this plugin.

Watch out — Browser notifications require manual permission on first load, and the channel will degrade silently if refused. It passed sandbox testing by installing into a new profile and registering with Harness. No obvious issues found.

The verdict — I would install it because it provides notifications without needing to monitor the session list dots, but only if you set up at least one third-party messaging service.

What it is — Converts coding activities into RPG by awarding XP for turns, tool calls, and todos.

Who it is for — When using DeepSeek Harness to handle agent tasks, this plugin automatically scores your turns, tool calls, and todos. If you are already using another progress tracking tool, you can skip it because it turns your work into a game with XP.

Watch out — No obvious issues were found. Sandbox test confirmed successful registration into the profile. No runtime dependencies.

The verdict — I would install it because it treats coding as the game itself through event-driven scoring, but only if you want automated progress tracking.

What it is — The forge-tcm plugin provides tcm_diagnose and tcm_herb_pair tools for eight-axes TCM diagnosis and herb-pair retrieval.

Who it is for — When using DeepSeek Harness to analyze traditional Chinese medicine texts, you can use the tcm_diagnose tool for eight-axes diagnosis. If you lack a formula_db.json dataset, it is not suitable for installation because the herb-pair tool requires it.

Watch out — Herb-pair retrieval requires a private formula_db.json dataset not distributed with the repo, so FORGE_DATA must be manually configured. Sandbox testing was not performed. No obvious issues found.

The verdict — If I needed TCM diagnosis capabilities, I would install it because it is a subdirectory plugin with zero npm dependencies.

What it is — BM25 keyword-based memory recall plugin, supporting memory query, list folding and deep preview.

Who it is for — When your DeepSeek Harness agent needs to recall experiences using BM25 algorithm in specific tasks. If you prefer to implement custom memory management from scratch, you can build it yourself.

Watch out — Requires preparing your own memory data files to use. No obvious issues found.

The verdict — I would install it because it offers folded memory indexing.

What it is — Provide verification gates for symbolic math simplification, logic proofs, regex validation, E-prover FOL theorem proving, state-machine checks, and code repair, backed by Go-compiled binaries with prebuilt Windows executables.

Who it is for — If you use DeepSeek Harness agent for tasks requiring symbolic math simplification or logic proofs, this plugin provides verified results. If your work only involves text generation without external tool execution, this plugin is irrelevant.

Watch out — This plugin executes shell commands and requires manually allowing the build script when installing from source. Static checks indicate it will execute shell commands. No obvious issues found.

The verdict — I would install it because it provides code repair suggestions based on compiled binaries, using the prebuilt Windows version.

What it is — The evidence-first plugin provides evidence_audit tool that warns the agent when it claims success without a matching tool-execution record in recent context.

Who it is for — When DeepSeek Harness agents complete multi-step tasks, this plugin can verify that each success claim is backed by actual tool executions. Users who rely entirely on direct text responses do not need it, since their workflows do not require tool record verification.

Watch out — No sandbox testing has been conducted. Static analysis indicates shell command execution. No obvious issues detected.

The verdict — I would install it if the task requires verifiable tool usage steps for reliability, as it adds an accountability mechanism; the key is whether the workflow demands such records.

What it is — dsh-skill-pack plugin provides workflow skills support for DeepSeek Harness.

Who it is for — This pack is suitable when performing triage tasks. If you only use the minimal preset for simple conversations, you need not install this plugin.

Watch out — Sandbox test passed: installed in a fresh profile and registered by Harness. No obvious issues found.

The verdict — I would install it because it declares no @deepseek-ai dependency and the profile injects the official packages at boot time.

What it is — Provides a desktop launcher for DeepSeek Harness Web UI on Windows, including shortcuts, system tray, and PWA app window support.

Who it is for — If you use DeepSeek Harness on Windows and want desktop shortcuts and system tray support for the Web UI. If your main environment is not Windows or you prefer browser-native workflows without extra system integration, you can skip this plugin.

Watch out — The plugin executes shell commands for launch and tray functionality. Sandbox test passed: installed in new profile and registered by harness. No obvious issues found.

The verdict — I would install it because it achieves desktop-like experience using only official mechanisms with no extra dependencies.

What it is — A resident plugin that displays real-time DeepSeek API account balance in the DeepSeek Harness composer dock statistics bar, with 5-minute auto-refresh and manual refresh button.

Who it is for — Users performing chat or code generation tasks with DeepSeek Harness who need to monitor API balance are suitable to install this plugin. Those who do not involve DeepSeek API balance monitoring can choose other plugins.

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

The verdict — I would install it because it provides real-time API balance visibility, but only if you have set up the DEEPSEEK_API_KEY credential and are willing to install from source code.

What it is — Scans the skills visible to the current session, ranks them by relevance to the recent conversation, and recommends the next skill to load.

Who it is for — Agents working across multiple skill domains who need fast skill recommendation based on conversation. Users who only focus on a single skill domain won't benefit from it.

Watch out — Sandbox test passed: installed in new profile and registered by harness. The plugin only reads session text and skill catalog with no network or write operations. No obvious issues found.

The verdict — I would install it because it provides a deterministic cross-domain skill matching signal, but the premise is using a supported DeepSeek Harness version.

What it is — dsh-qrcode plugin provides offline QR code and barcode generation.

Who it is for — In DeepSeek Harness offline sessions where you need to encode links or text into scannable QR or barcodes, install it. If your project uses networked models and doesn't need local rendering, another angle is that the plugin's pure local advantage isn't prominent in online scenarios.

Watch out — Sandbox test passed: the plugin installed in a fresh profile and registered by harness. Static check indicates it may execute shell commands, but no other obvious issues were found.

The verdict — I will install it because the sandbox test passed and it supports multiple output formats, but the premise is that tool injection is configured and offline code generation is required.
