Compatibility

Surface · Status Harness · DeepSeek Harness dsh-v0.2.1-alpha.1 (verified 2026-10-04: three typecheck rulers (installed, CI, checkout) + 142 tests + self-contained/artifacts gates; the 0.1.7 content-block union is adapted — a tool result is a first-class tool-role message, and a pre-0.1.7 tool-result wrapper is still read for old logs). The peer range admits every supported line: >=0.1.2-rc.1 =0.1.5-alpha.1 =0.1.6-0 =0.1.7-0 =0.2.0-0 =0.2.1-0 =24.0.0 Backend · Ollama (local HTTP API + CLI probe) Model · Text-only route (inputModalities: ['text']); tool calls and tool results are supported

What you get

dsh-local-ai makes Ollama a first-class local provider in DeepSeek Harness:

• Discovery & management — ollama_list (installed models, running models, disk usage), ollama_show (parameter size, quantization, context length), ollama_pull, and ollama_remove.
• Health check — process liveness (via the ollama CLI) and API responsiveness (via /api/version), reported as two independent signals.
• Official adapter — the ollama provider route is registered through ctx.llm.registerAdapter (LlmAdapter), with configurable model mapping and temperature / max-tokens / stop translation.
• OpenAI-compatible backends — LM Studio, vLLM, and llama.cpp --server each register as their own openai: provider through the same LlmAdapter seam, reusing one OpenAI /v1/chat/completions adapter (text-only route).
• Local routing — model_route rules route requests to a local model by task type (purpose), case-insensitive keyword, or always, with automatic fallback to the cloud when the local route fails before producing content.
• `/ollama` command — a one-shot status overview: models, disk usage, health, and suggestions.
• Zero dependencies, HTTP first — everything talks to Ollama's HTTP API (the CLI is used only for the process probe); no model files are bundled.

Quick start

dsh plugin --profile web add github:PerryLink/dsh-local-ai

# 1. install the bundle into your profile
dsh plugin --profile web add github:PerryLink/dsh-local-ai

# or from npm (published releases)
dsh plugin --profile web add dsh-local-ai

# 2. configure routing in your profile patch (cordis.yml) and restart
dsh --profile web

Minimal routing configuration (the rule ships commented out in cordis.patch.yml):

- insert:
    - id: dsh-local-ai
      name: dsh-local-ai
      config:
        route:
          - model: llama3.2
            keywords: ["confidential", "offline"]

Then verify the row mounts:

dsh --profile web --dump-config | grep -A2 'id: dsh-local-ai'

Examples

These are the plugin's real entry points; install once, then call one.

Tools & surfaces

Surface · Kind · What it does ollama_list · tool · List installed models, running models, and disk usage ollama_show · tool · Show parameter size, quantization, context length, family, format ollama_pull · tool · Pull (download) a model ollama_remove · tool · Remove a model ollama_health · tool · Process liveness + API responsiveness /ollama · command · One-shot status overview (models + health + suggestions)

Consumes the public host services ctx.llm (registerAdapter), ctx.tools, ctx.subprocess (CLI probe), and ctx.commands. It registers no llm/stream short-circuit by default — the routing listener passes through (next()) unless a rule matches.

Permissions & data

• Permissions: network:outbound to the Ollama endpoint you configure; no native code, no filesystem access, no storage.
• Data: every model list/detail, health fact, and error message shown to the model or the user is sanitized (endpoint userinfo and secret query params dropped, control characters stripped, lengths bounded) before display. Tool and command results are logged by the harness's own tool/command seams.
• Credentials: the plugin stores and reads no credentials. It only issues HTTP requests to the endpoint you configure, plus the local ollama list process probe.

Security boundaries

• No re-routing by default — the route list is empty unless you opt in; a request reaches a local model only through an explicit rule or an explicit ollama provider selection.
• Sanitize before display — endpoint addresses and local paths are sanitized before they reach tool output, the /ollama command, or error messages.
• Zero bundled models — downloads and storage are Ollama's own responsibility; nothing is shipped in the package.
• Failure loud, failure contained — invalid config fails the mount; a local route that fails before producing content falls back to the cloud (next()), so a down Ollama never bricks a conversation. One carve-out: a failure carrying IMAGE_OFFLOAD_REQUIRED is rethrown instead of retried on the cloud — that code is the official offload circuit asking this same local route to drop retained images, and falling back would skip the circuit while silently sending a local-only request to a remote provider.
• Model-visible ⟺ logged — routing only changes which provider serves a request (the assistant message is logged with its ollama provenance); no new model-visible input is invented.

Known limitations

• npm 0.2.0-rc.2 — developed and tested against @deepseek-ai/dsh@0.2.0-rc.2; newer harness baselines are expected to work but are verified by the monthly compat workflow.
• Vision when the model reports it — models whose /api/show capabilities include vision declare inputModalities: ["text","image"] and carry base64 image payloads on user messages (opt out with vision: false); text-only models still reject image content (UNSUPPORTED_CONTENT).
• Mid-stream fallback — once a local route has started producing content, a later failure is forwarded (not retracted); only a failure before the first token falls back to the cloud.

Interoperability with other DSH plugins

Verified against DSH `0.2.0-rc.2` (the runtime this README ships for) and the high-star plugin set surveyed on 2026-10-05.

This plugin does not interfere with other plugins, including the widely installed high-star ones:

• No tool-name collision. Every tool is namespaced; no bare name owned by a shipped tool or another plugin is registered.
• No service-key collision. It provides no service key at all, so it cannot collide on one.
• No slot collision. It registers no client slot key, so it cannot contend for a shadows-shipped-ui seat.
• No HTTP route collision. It registers no webServer prefix.
• No patch-layer collision. The bundle patch only inserts its own row; it never overrides a built-in row's config.
• No global mutation. It does not patch prototypes, rewrite process.env, or replace the global fetch dispatcher.

Shared event listeners are non-interfering by construction. It observes the ordering-sensitive event llm/stream with ctx.on() — Cordis's broadcast registration, where every listener runs and none can starve another. Every listener here delegates through `next()`, so the chain is never short-circuited, and a mutation is applied to the value next() produced rather than returned in its place:

• llm/stream — also used by dsh-routing-suite (7000★).
