Best DeepSeek Harness Plugins for Developers (2026)
Best DeepSeek Harness (dsh) plugins for plugin developers and power users: health checks, security audits, context-cost auditing, and a plugin template.
If you're building your own DeepSeek Harness (dsh) plugins or just running enough of them that you want visibility into what's actually installed, the Development & Runtime category is where the tooling lives. By real GitHub stars, the top picks are oh-dsh and forkprobe — with strong picks further down covering plugin health checks, security audits, and context-cost diagnostics. Full list and install commands below.
What sets this category apart
Most plugin categories on FindHarness add a capability to what the agent can do — vision, search, memory. Development & Runtime is different: these plugins add capability to what you can see and control about your dsh setup itself. A health checker that scans your installed plugins for manifest problems, a security auditor that reports what your config actually exposes, a context-cost profiler for your instruction chains — none of these make the agent smarter, but they make running a non-trivial plugin stack safer and less opaque.
If you're writing a plugin from scratch rather than just managing installed ones, start with Build a DeepSeek Harness Plugin from Scratch instead — this list is about the tooling that supports plugin developers and power users, not the tutorial itself.
The list
This ranking uses only the curated awesome-dsh-plugin collection (source=awesome) — not the auto-discovered plugins also indexed on the full Development & Runtime category page, which holds 72 plugins as of August 2026, the third-largest category in the catalog. Stars are a snapshot as of August 2026.
| # | Plugin | Stars | What it does |
|---|---|---|---|
| 1 | oh-dsh | 168 | TUI + desktop + Web UI as one layered distribution |
| 2 | forkprobe | 65 | Compares skills on the same task, picks the winner |
| 3 | plugin-registry | 36 | Browser console for official-repo plugins + a make-dsh-plugin skill |
| 4 | dsh-multica-runtime | 31 | Run dsh on Multica |
| 5 | dsh-user-experience | 18 | Auto-reviews React/TypeScript for UX issues |
| 6 | dsh-plugin-check | 17 | Read-only manifest/patch/build health checks |
1. oh-dsh — 168 stars
Category: Development & Runtime · Repo: hust-open-atom-club/oh-dsh
The most-starred plugin in this category by a wide margin — a community distribution rather than a single-purpose tool. It bundles the TUI, desktop client, and Web UI into one installable package with layered installation, backed by an established open-source organization (Open Atom Club, HUST) rather than a solo repo. If you want one consistent setup across interfaces instead of assembling each client separately, this is the most-adopted starting point.

2. forkprobe — 65 stars
Category: Development & Runtime · Repo: jayden-x-l/forkprobe
A genuinely useful idea for anyone iterating on skills: forkprobe runs multiple skills against the same task in parallel and helps you pick the winner. If you're maintaining more than one version of a skill and guessing which one performs better, this replaces the guessing with a side-by-side comparison.

3. plugin-registry — 36 stars
Category: Development & Runtime · Repo: vlln/plugin-registry
Ecosystem infrastructure rather than a single feature: a thin browser console for managing official-repository plugins (zero-patch, so it doesn't add its own config layer), plus a make-dsh-plugin skill that guides you through building a new plugin step by step. Useful both as a management surface and as scaffolding for your own plugin's first draft.

4. dsh-plugin-check — 17 stars
Category: Development & Runtime · Repo: omdsh-dev/dsh-plugin-check
A zero-dependency, read-only plugin health checker: it validates manifest protocol compliance, patch format correctness, and common build traps — the kind of mistakes that surface as a confusing runtime error rather than a clear message at install time. Run this against a plugin you're developing before you ship it, or against something you're about to allowBuilds for on someone else's plugin.

5. dsh-security-audit — 10 stars
Category: Development & Runtime · Repo: omdsh-dev/dsh-security-audit
A local security audit tool: config, plugin origins, sessions, and network exposure, reported as a read-only, redacted risk report. Given that dsh's own docs warn that allowBuilds and GitHub-sourced plugins execute code on your machine outside any agent sandbox (see How to Vet a DeepSeek Harness Plugin), a plugin whose entire job is auditing what you've already installed is worth running periodically, not just once.

6. dsh-context-doctor — 7 stars
Category: Development & Runtime · Repo: zhenyu98/dsh-context-doctor
A context-injection auditor: it reports the token costs of instruction chains, skill catalogs, and tool schemas, and flags duplicate or conflicting entries. If your session is loading a growing stack of plugins, skills, and MCP servers and you're not sure what's actually eating your context budget, this is the diagnostic built for that question.

Also in this category: dsh-multica-runtime (31 stars, runs the dsh runtime on Multica), dsh-user-experience (18 stars, auto-reviews React/TypeScript code for UX issues), fabric (9 stars, an MC-Fabric-style hook processor), dsh-session-health (9 stars, frame-level scan diagnostics for torn/corrupt/empty session files), dsh-git-identity (7 stars, pins Git commits to the environment's own author identity), dsh-fail-logger (7 stars, deduplicates and logs failed tool calls into a skill so repeated mistakes fade, published to npm), dsh-updater-ui (6 stars, a self-updater panel with one-click git pull --ff-only and changelog preview), dsh-evolve (5 stars, an experimental self-evolution plugin that lets the agent hot-mount/remove plugins on itself mid-session), and plugin-template (5 stars, a starter repo based on the official turtle-ui template).

FAQ
Are any of these an official scaffold or create-dsh-plugin CLI?
No — there's no official plugin scaffolding tool in the dsh repository as of August 2026. plugin-template and plugin-registry's make-dsh-plugin skill are the closest community substitutes, but neither is an official deepseek-ai-maintained tool.
Should I run dsh-security-audit before or after installing new plugins?
Both, ideally. Run it as a baseline after your initial setup, and again after adding plugins from sources you haven't fully vetted — especially anything installed via github:owner/repo with allowBuilds granted, since that's the install path with the least built-in scrutiny.
Is dsh-evolve safe to run in a real project?
Treat it carefully — letting an agent hot-mount and remove plugins on itself mid-session is exactly the kind of self-modifying behavior that's harder to reason about from a permissions standpoint. The plugin's own description frames it as self-evolution, which is a genuinely interesting idea, but it's not something the official docs have anything to say about, so evaluate it with the same scrutiny you'd give any other GitHub-sourced install.
What's the difference between dsh-plugin-check and dsh-context-doctor?
dsh-plugin-check validates a plugin's manifest, patch format, and build correctness before or after install — it's about whether a plugin is well-formed. dsh-context-doctor is about runtime cost: how many tokens your active instruction chains, skills, and tool schemas are actually consuming once everything is loaded. They answer different questions and are worth running together.
