omicverse/dsh-omicos

@omicverse/dsh-omicos

Run OmicVerse/OmicOS bioinformatics analyses from inside DeepSeek Harness. The dsh agent keeps the wheel; this plugin gives it a persistent Python kernel (scanpy / omicverse / R) plus the catalog of analysis skills that OmicOS ships.

dsh plugin --profile web add @omicverse/dsh-omicos

Tools

One tool runs an analysis; the rest are direct reads of the local kernel that cost neither a turn nor a token.

Commands

/omicos-help (what the plugin adds, and where to look), /omicos-login (device-code pairing — sign in with phone or email in the browser), /omicos-status, /omicos-account, /omicos-logout, /omicos-stop-kernel.

Deliberately short: commands are for what the agent cannot do for you. Listing variables, browsing capabilities or finding outputs is better asked of the agent, which has tools for exactly that.

UI

The client bundle adds two surfaces to the web profile:

• an OmicOS tab next to the conversation — a small console: sign-in state, plan and expiry with links to subscribe or manage; which kernels are attached, where, at what version, and what is bound in them right now; and a search box over the installed capability catalog;
• a live tool view on omicos_analyze calls — the steps, tool calls and stdout tail as the analysis runs, instead of a spinner that ends in a wall of text. Generated figures render in the settled card.

If dsh-better-sidebar is installed, an “OmicOS 产物” tab is registered there too; the integration is optional and detected at runtime.

Requirements

• omicos-core comes with the install. @omicverse/omicos is a dependency, so the ~21 MB platform binary lands in node_modules alongside the plugin rather than being fetched by npx in the middle of your first tool call. At run time the plugin still attaches to a kernel you already have running (desktop app or terminal) if there is one, spawns the bundled binary only when there is not, and only ever stops a kernel it started itself.
• An OmicOS account for cloud-backed models and the higher plan tiers. Sign in with /omicos-login; no token is ever persisted by this plugin — the approved login is handed to the local core, which keeps it.
• dsh 0.1.0-rc.6. Note that some @deepseek-ai/dsh-* packages have a stale latest dist-tag pointing at 0.0.1-rc.x, so every dsh dependency here is pinned exactly.

Configuration

Override in your profile’s own cordis.patch.yml. A patch replaces the row’s whole config — there is no deep merge — so restate every key you care about:

- id: omicos
  config:
    workspace: /path/to/project   # '' = follow each dsh session's own cwd
    autoStart: true               # spawn a kernel when none is attachable
    upstreamBaseUrl: https://auth.omicos.cn
    npmRegistry: ''               # mirror knob for the kernel spawn

Security posture

• Tools run in core with permission_mode: "full". A single-shot tool result has no room for a mid-flight approval prompt, and blocking on one deadlocks the turn; bridging dsh’s approval UI into an OmicOS turn is planned, not done.
• Catalog search projects before it answers: the skill source_path (an absolute local path) and the verbatim use_when routing text are indexed but never returned, so they do not travel to the model.
• The plugin’s HTTP routes are pinned to loopback.

Development

pnpm install
pnpm build       # tsc + the client bundle
pnpm typecheck
pnpm test        # 89 tests against the real dsh defineTool and a mock core

This package publishes as ONE dependency-light artifact: the @omicverse/omicos-* SDK is inlined by esbuild.host.mjs and kept as devDependencies, while @deepseek-ai/* stays external (the harness supplies it, and a second copy of Schema would fail config validation) and @omicverse/omicos stays a real dependency (it is spawned as a child process, never imported).

src/host/dsh-compat.ts is the only module allowed to import @deepseek-ai/*. bridge.ts / kernel.ts / runner.ts / auth.ts have no dsh dependency at all, so a dsh API change is absorbed in the compat layer plus tools.ts, commands.ts and index.ts.
