A working DeepSeek Harness setup in one command. Every set below was installed into a clean profile as a single install, and every plugin in it was confirmed to register — not checked one at a time and assumed to get along.
Why a set is a different claim
Each listing in this catalogue carries a verdict from installing that plugin into an empty profile. That is the right test for a listing and the wrong one for a set, because combinations fail where the parts do not:
two plugins wanting incompatible versions of the same peer
a build script pnpm only blocks once another plugin has dragged in the dependency that owns it
cordis refusing a duplicate loader entry id — so a plugin installs, reports success, and is never registered
So each set here was run through the sandbox as one install of the whole list, using the exact command printed beside it, and every member had to appear in the profile's bundle list afterwards. Anything less does not ship. A set that quietly drops a plugin is worse than no set at all: you would believe you had a capability you do not have.
The sandbox is open source, as is the CLI. The dates and versions below are what the run actually reported.
Essentials
5 plugins
Memory that survives a restart, search that reads the repo, an undo for the last turn, and a running token count.
Cross-agent, local-first persistent memory plugin for DeepSeek Harness (DSH), powered by Mnemon. It shares long-term memory across Mnemon-enabled agents and adds runtime memory, searchable project documents, semantic recall, knowledge graph, and a Sidebar UI.
Sidebar usage panel that attributes tokens to the relay site that served each request, read from your existing provider config: today/month/all-time totals, per-site and per-model breakdowns, a year activity heatmap, and New API / Sub2API / DeepSeek balances.

Vision
3 plugins
Three plugins that all want to handle images, verified as not fighting each other over it.
@liustack/modlens
ModLens for dsh-TUI: plug-in vision for text-only LLMs in the terminal. Fork of liustack/modlens with terminal-front-end adaptation.
dsh-vision-router
Free vision for text-only agents: built-in keyless vision chain plus pixel tools (Q&A, grounding, crop, pixel diff, colors, OCR, SVG trace, cutout, screenshots); paste an image to use it.
Vision for text-only models: paste an image and the model switches to a Vision Toolkit variant for image Q&A, multi-image comparison, long-screenshot OCR, screenshot-to-UI reproduction, element grounding, and pixel diff. No API key by default — images are processed by the author-hosted free service, 100 per machine per day; configurable to your own provider.

Needs one build script approved:node-pty@1.1.0 — pnpm will not run it until it is allowlisted, and until then the harness may never register the plugin. The command above does it for you.
These will grow
Three to start, and more as combinations are verified — the constraint is sandbox time, not ideas. If a set you want does not exist, or one of these is missing something obvious, say so and it can be tested.
Building your own instead? GET /api/v1/presets serves all of this as JSON, including the verification metadata, and the API is open — no key, CORS included.
