dsh-claude-code-local

Use your locally installed Claude Code as an LLM provider in DeepSeek Harness (DSH).

The plugin registers a claude-code provider route. Each model request spawns your local claude CLI in streaming JSON mode; Claude Code runs its own agentic loop (its built-in tools, permission mode, max turns) and the streamed text is translated into the harness chat in real time.

• Pick the provider in the composer's model selector — group Claude Code (local).
• No API key in DSH: the CLI uses its own stored credentials (~/.claude, ANTHROPIC_API_KEY, OAuth, Bedrock/Vertex, ...).
• Your existing Claude Code setup keeps working: skills, commands, MCP servers, permission modes.
• macOS/Linux only.

Requirements

• DeepSeek Harness 0.1.0-rc.7 or newer (web, headless, or the DSH Desktop app).

• The Claude Code CLI installed and authenticated:

  claude --version
  

Installation

Option 1: DSH Desktop community market

1. Open the Market page in DSH Desktop.

2. Sources → add a source with this manifest URL:

   https://raw.githubusercontent.com/NGdust/dsh-claude-code-local/main/catalog/manifest.json
   

3. Select the source, open Discover, find Claude Code (local), and install it. Restart the app when prompted.

Option 2: dsh CLI

dsh plugin --profile web add dsh-claude-code-local
dsh --profile web

For a headless profile, replace web with the profile name. Restart the server after installing.

Option 3: manual (offline / air-gapped)

Copy this package into the profile module farm and register the plugin row in the profile patch layer:

cp -R dsh-claude-code-local ~/.dsh/profiles/node_modules/

Then add to ~/.dsh/profiles/web/cordis.patch.yml:

- insert:
    - id: llm-claude-code
      name: dsh-claude-code-local

A running web app picks the row up without a restart (the patch is hot-watched); the DSH Desktop app applies it on the next launch.

Verify

Open the composer's model selector (or the Models page) and look for the Claude Code (local) group with the model lineup (claude-opus-5, claude-sonnet-5, claude-haiku-4-5, claude-fable-5). Select any of them and send a message — the reply streams from your local CLI.

Configuration

Settings live in the llm-claude-code: section of $DSH_HOME/settings.yaml (default ~/.dsh/settings.yaml) and are hot-reloaded — no restart needed:

llm-claude-code:
  permissionMode: auto        # auto | acceptEdits | bypassPermissions | manual | dontAsk | plan
  maxTurns: 10                # internal agent steps per request
  streamIdleTimeoutMs: 300000 # kill the request if the CLI is silent this long (ms)

All options

Key	Default	Description
executable	claude	Path or name of the Claude Code CLI. Set an absolute path (see which claude) if the CLI is not on the harness PATH.
model	""	Model passed to claude --model. Empty: use the picker selection. default: omit the flag and let the CLI pick.
permissionMode	auto	Claude Code permission mode. bypassPermissions is dangerous.
allowedTools	[]	claude --allowedTools list, e.g. ["Bash(git *)", "Read"].
disallowedTools	[]	claude --disallowedTools list.
tools	unset	Raw claude --tools override. "": disable Claude's built-in tools (pure text). default: restore them.
maxTurns	10	Max internal agent steps per request.
appendSystemPrompt	true	Append the harness system prompt to Claude Code's own.
cwd	unset	Working directory for the CLI; unset inherits the harness cwd.
noSessionPersistence	true	Don't write Claude Code session files to disk.
extraArgs	[]	Extra raw CLI arguments (advanced).
streamIdleTimeoutMs	300000	Idle watchdog between streamed events, in milliseconds.
models	current lineup	Advisory catalog shown in the picker (see below).
retryPolicy	harness default	LLM retry policy.

Model catalog

The models list controls what the picker offers. The default lineup is what the installed CLI resolves today (opus → claude-opus-5, sonnet → claude-sonnet-5, haiku → claude-haiku-4-5, fable → claude-fable-5). Override it to pin or extend the list:

llm-claude-code:
  models:
    - id: claude-opus-5
      name: Claude Opus 5
      contextWindow: 200000
    - id: claude-sonnet-5
      name: Claude Sonnet 5
      contextWindow: 200000
    - id: claude-haiku-4-5
      name: Claude Haiku 4.5
      contextWindow: 200000
    - id: claude-fable-5
      name: Claude Fable 5
      contextWindow: 200000

The list is advisory: the CLI decides which models your account can actually serve, and a model that is not in the list is still served if it is selected.

Make it the default provider

New sessions default to the profile's agent-default-model (DeepSeek). To default every new session to local Claude Code:

agent-default-model:
  provider: claude-code
  model: claude-sonnet-5

Or just pick the provider per session with the composer's model selector.

Permission modes

• auto (default): Claude Code's auto-mode classifier — safe actions run, risky ones are denied in non-interactive mode.
• acceptEdits: file edits are auto-approved.
• bypassPermissions: dangerous — Claude Code can do anything its tools allow (equivalent to --dangerously-skip-permissions).
• manual / dontAsk / plan: see the Claude Code CLI docs.

Troubleshooting

Symptom	Fix
Provider not in the model picker	The plugin is not loaded. Re-check the install step; restart the server (DSH Desktop applies changes on the next launch).
spawn claude ENOENT / claude: command not found	Set executable to the full path: llm-claude-code: { executable: /path/to/claude } (see which claude).
Auth / account errors on first message	Log in once: run claude interactively, or check ~/.claude / ANTHROPIC_API_KEY. The plugin never asks DSH for an API key.
Long agentic runs get cut off mid-stream	Raise streamIdleTimeoutMs (e.g. 600000) — the request is aborted when the CLI stays silent longer than the timeout.
File edits are blocked	Use permissionMode: acceptEdits. Note: DSH's sandbox does not gate Claude Code's actions — the CLI's permission mode does.
Nothing happens on Windows	Not supported. Use macOS, Linux, or WSL.

How it works

1. apply() registers the claude-code route with a ClaudeCodeAdapter and declares it in the configurable-provider directory, so the model picker and Models page know it.
2. Each request spawns claude -p --output-format stream-json --include-partial-messages --verbose <flags> with the rendered conversation piped over stdin (long histories never hit OS argument-length limits).
3. stream_event/result JSON events are translated into harness chunks: text deltas → chat text, thinking deltas → reasoning, tool use → a liveness line (Claude Code tool: ...), usage → token counts.
4. The child is killed on caller abort or idle timeout.

Limitations

• Each request is a fresh stateless CLI invocation; the full conversation is re-rendered every turn (no cross-request prompt-cache reuse).
• The harness's own tools are not used through this provider: Claude Code owns its loop, so DSH's sandbox/permission service does not gate Claude Code's actions — the CLI's permissionMode does.
• maxTokens / temperature / stop from the harness request are ignored; the CLI controls sampling.
