Compatibility

Surface	Status
Harness	DeepSeek Harness 0.1.0-rc.6
Node	^22.19.0 || >=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.
• 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

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

# 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'

Install & uninstall

• git channel (latest main): dsh plugin --profile web add "github:PerryLink/dsh-local-ai#main" — the prepare script builds with production dependencies only.
• npm channel (published releases): dsh plugin --profile web add dsh-local-ai.
• tarball channel: pnpm pack in this repo, then dsh plugin --profile web add ./dsh-local-ai-<version>.tgz.
• uninstall: dsh plugin --profile web remove dsh-local-ai (or remove the row from the profile patch).

If pnpm reports ERR_PNPM_IGNORED_BUILDS for this package, add allowBuilds: { esbuild: true } to your pnpm-workspace.yaml — the dsh CLI prints the exact snippet.

Configuration

All tunables are Schemastery Config fields (changeable from cordis.yml). An id-targeted override replaces the whole row — restate every key you need. cordis.patch.yml documents each key inline.

Key	Default	Meaning
baseURL	http://127.0.0.1:11434	Ollama HTTP API base URL; /api/* paths are appended
requestTimeoutMs	30000	Per-request HTTP timeout (milliseconds)
graceMs	15000	Subprocess terminate grace for the health-check CLI probe
defaultContextWindow	8192	Context capacity used when a model has no exact value
maxTokens	4096	Per-request output cap used when a model has no exact value
temperature	(none)	Default sampling temperature (0..2); omitted leaves the provider default
models	[]	Harness-visible → Ollama model mappings
models[].name	(required)	Harness-visible model name (GenerateOptions.model)
models[].model	= name	Ollama model id
models[].contextWindow	(none)	Per-model context capacity
models[].maxTokens	(none)	Per-model output cap
models[].temperature	(none)	Per-model sampling temperature
route	[]	Local-model routing rules (first match wins)
route[].model	(required)	Target local model name
route[].purpose	(none)	Task type match: compaction / session-title
route[].keywords	[]	Case-insensitive request keywords
route[].always	false	Route every eligible request to this model

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.
• 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

• rc.6 only — developed and tested against @deepseek-ai/dsh@0.1.0-rc.6; newer harness baselines are expected to work but are verified by the monthly compat workflow.
• Text-only route — image content is rejected (UNSUPPORTED_CONTENT); multimodal local models are not wired up yet.
• 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.
