OpenAI-compatible HTTP surface for DeepSeek Harness (dsh): POST /v1/chat/completions, POST /v1/responses, GET /v1/models over the harness webServer + llm runtime

Project Overview项目介绍

This is a native plugin built exclusively for DeepSeek Harness (DSH) that exposes an OpenAI-compatible HTTP API surface backed by live DSH agent sessions. To install it, you run either dsh plugin --profile web add github:huyang2024/dsh-openai-api to pull from GitHub, or add a local checkout via the file path. After installation, you must add an inject entry to your DSH profile’s cordis.patch.yml file, then restart the profile to activate the plugin. Once active, it serves three endpoints: /v1/chat/completions, /v1/responses, and /v1/models. Unlike a thin LLM proxy, every API request is routed through a live DSH agent that has access to all the tools, file system access, skills, and persona configured in your DSH profile.

Each session is uniquely identified by a combination of API key tenant and the optional X-Agent-Preset request header. Each distinct API key gets its own separate tenant space, so different clients will never share a session even if they target the same agent preset. If no API keys are configured in the plugin settings, the service only accepts requests from loopback addresses, a hardening measure to prevent accidental unauthenticated exposure of agent access to the local network. Client-side tool definitions are ignored entirely; the DSH agent always controls which tools get called and the flow of execution for each request.

This plugin is released under the permissive MIT open source license, with no associated cost or restrictions on use. To connect to the API, you can use any standard OpenAI API client by pointing its base URL to your local DSH endpoint and using any configured API key for authentication. Local development can be done by cloning the repository, checking syntax with node --check lib/index.js, and running smoke tests against a faked agent service with node test/smoke.mjs. Cross-origin requests from unauthenticated browsers are blocked by default unless explicitly allowed via the plugin’s allowedOrigins configuration option.

这是一个专门为DeepSeek Harness(DSH)开发的原生插件,为DSH提供了兼容OpenAI API标准的HTTP服务接口,依托DSH本身实际运行的代理会话提供服务。安装完成后,DSH的Web服务器会额外开放三个标准端点:聊天补全接口、Responses API子集接口、模型ID获取接口,所有请求都由运行中的DSH原生代理会话处理,它并非简单的LLM反向代理,而是让每个调用都能获得DSH代理的完整能力,包括配置好的工具、文件访问、技能和预设人设。

典型使用流程是,用户通过DSH命令行将插件安装到指定DSH配置文件后,修改配置文件插入该插件,配置好路径前缀、允许的API密钥、默认模型和工作目录等参数,重启DSH配置后即可使用。任意兼容OpenAI API标准的客户端都可以连接该接口,调用DSH原生代理的能力。这个插件面向需要将现有OpenAI API客户端对接进DSH生态的开发者。

该插件采用MIT许可证开源,无使用成本,会话标识通过API密钥租户和X-Agent-Preset请求头区分,不同密钥对应独立会话,未配置API密钥时仅允许本地回环访问,避免未授权访问风险。首次运行需要配置DSH的web配置文件补丁,完成后重启对应配置文件才能生效。

OpenAI-compatible HTTP surface for DeepSeek Harness, backed by real DSH agent sessions.

After this plugin is installed into a dsh profile, the harness web server additionally serves:

Endpoint Purpose
POST /v1/chat/completions Chat Completions API (streaming + non-streaming)
POST /v1/responses Responses API subset (streaming + non-streaming)
GET /v1/models Advertised model id

What "agent-backed" means

Each request is served by a live DSH agent session (the harness agents registry + the agent loop), so every call gets the agent's full world: its configured tools, bash/files access, skills, prompt sections, and preset persona. This is an agent gateway, not a thin LLM proxy:

  • The agent owns tool use. Client-side tools / tool_choice / function-call messages are rejected — the agent decides what tools to call and why.
  • Streaming deltas arrive once per committed assistant message, not per token. Reasoning, tool calls, and token-level chunk streams stay off the wire; only committed assistant text reaches the client.
  • The first request for a (key, preset) pair seeds a session by rendering the client's full message array into a labeled transcript prompt; later requests admit only the latest user turn (the session already holds the history).

Session identity

(API key tenant, X-Agent-Preset):

  • The accepted apiKey namespaces the caller — one session per key, so different keys never share a session even for the same preset, and a client resumes its own session on reconnect.
  • The X-Agent-Preset header names the preset the session joins (absent → the profile default). Resolved only at session creation.

Install

# from GitHub
dsh plugin --profile web add github:huyang2024/dsh-openai-api

# or from a local checkout
dsh plugin --profile web add file:/absolute/path/to/dsh-openai-api

Then compose an insert in the profile's user patch layer — $DSH_HOME/profiles/web/cordis.patch.yml. New rows reach the tree only through insert::

- insert:
    - id: openai-api
      name: '@huyang2024/dsh-openai-api'
      inject: [webServer]
      config:
        pathPrefix: '/v1'     # optional, default shown
        apiKeys: []           # optional; see below
        model: default        # optional; model id advertised at /v1/models
        provider: ''          # optional; provider route for created sessions
        cwd: ''               # optional; absolute working directory for sessions
