DeepSeek Harness plugin: subagent_routed — run a one-shot subagent fully mounted on ANY agent preset from ANY session, with per-call model/provider override and a model-availability pre-check.

Project Overview项目介绍

dsh-routed-subagent is a native DeepSeek Harness plugin built exclusively for DSH, adding a custom subagent provider that overrides DSH's default stock subagent behavior. The default stock subagent and subagent_fork tools force child subagents to inherit the parent session's preset, but this plugin lets users dispatch one-shot child subagents mounted fully to any target agent preset. It supports per-call override of the child's LLM model and provider, and runs a pre-check to confirm model availability before dispatching the child. The child subagent adopts the entire configuration of the target preset, including persona, prompt structure, skill catalog, and available tools. This integration follows DSH's official subagent ecosystem conventions.

By default, subagent tasks run in the background, so the call returns a job ID immediately and lets users continue working in the main session or dispatch multiple child subagents in parallel. Aborting the main conversation does not cancel running background child tasks, which can be stopped explicitly with the job_kill tool if needed. In addition to DSH-native preset-mounted subagents, this plugin supports dispatching subagents to external CLI agents, including OpenAI Codex CLI, Anthropic Claude Code SDK, and CodeBuddy Code CLI. Each external engine supports background execution, live progress streaming, explicit model selection, and task killing, with Codex and CodeBuddy also supporting continuable resumed sessions.

This plugin is distributed only via GitHub and is not published to npm, so users need to manually mount the package directory to install it, and it targets DSH rc.7 or newer. To enable continuable sessions with preset mounting, it adds an incremental patch to the official @deepseek-ai/dsh-subagent package, which requires a junction at install time and a runtime check on startup. The plugin can disable the default stock subagent tools automatically to avoid duplication, it is released under the MIT license, and it is built as a plain ESM package with zero build step required. Users can roll back the patch at any time by restoring the original package junction.

这是一个专为DeepSeek Harness(DSH)开发的原生插件,允许任意会话调度挂载到任意代理预设的一次性子代理,支持每次调用覆盖模型和服务商,还会提前检查模型可用性。它替换了DSH原生的subagent/subagent_fork工具,这些原生工具强制子代理继承父会话的预设,而该插件允许子代理完全采用目标预设的完整配置,包括角色人设、提示片段、技能目录和工具集。

默认情况下子代理任务在后台运行,可并行调度多个子任务,调用会立即返回任务ID,中止主会话不会取消子代理任务,可通过job_kill手动停止。该插件支持外部CLI代理调度,除了默认的DSH内核引擎,还支持Codex CLI、Claude Code SDK、CodeBuddy Code CLI三种外部引擎,均可实现后台运行、进度实时展示和任务终止,每个引擎都支持显式指定模型,Codex和CodeBuddy还支持任务续跑。

该插件仅通过GitHub分发,未发布到npm,需要手动挂载包目录安装,兼容DSH rc.7及以上版本。为了支持可续跑的预设挂载,它对官方dsh-subagent包做了增量补丁,安装时需要创建安装级软连接,启动时会检查补丁是否正确加载。插件默认禁用原生子代理工具,采用MIT许可证,本身是纯ESM包,无需构建步骤即可使用。

dsh-routed-subagent

License Version CI

A global DeepSeek Harness plugin that lets any session dispatch a one-shot subagent fully mounted on ANY agent preset, with per-call model/provider override and a model-availability pre-check.

The stock subagent / subagent_fork tools force children to inherit the PARENT's preset. This plugin replaces that with a custom subagent provider whose async child setup calls agentPresets.mount(childCtx, <preset>) — so the child adopts the TARGET preset's complete composition: persona, prompt sections, skill catalog, and tools.

Features

  • Background by default, parallel dispatch — the call returns a job id immediately (like the stock subagent tool); the conversation stays free to do other work or dispatch more children in parallel, and aborting the conversation does NOT cancel the child (stop it with job_kill). Set run_in_background: false to wait inline.
  • Full preset mount — the child runs under the target preset's standing composition (not a persona copy): identity, mission section, skills, tools.
  • Per-call model override — model / provider arguments route the child's LLM call to a different model than this session's (via the official resolveChildAgentOptions channel).
  • Model pre-check — an invalid model fails fast with the provider's candidate list instead of an opaque child failure.
  • Official subagent ecosystem — one-shot lifecycle events, UI rows, trajectory; returns the child's final output.
  • Idempotent provider registration — multiple presets can mount the row; the host-plane provider registry is never duplicated.

External engines (engine=...)

subagent_routed can also dispatch the subagent to an external CLI agent instead of an in-harness preset mount. The default engine is dsh (this plugin's kernel); alternatives:

engine driver background job live progress kill explicit model continuable
dsh (default) preset-mount provider ✅ ✅ ✅ ✅ ✅
codex codex CLI app-server --stdio ✅ ✅ (process event stream) ✅ turn/interrupt ✅ thread/start model ✅ same-thread resume
claude Claude Code SDK ✅ ✅ ✅ abortController/close ✅ ⚠️ official Anthropic API only
codebuddy CodeBuddy Code CLI --print ✅ ✅ (NDJSON stream) ✅ process kill ✅ --model ✅ --session-id / --resume
