DeepSeek Harness 的实证优先模型控制平面

Project Overview项目介绍

dsh-switch is an evidence-first model control plane plugin for DeepSeek Harness. It exposes two capabilities: a DSH bundle that inspects registered provider routes, validates exact provider/model through the official ctx.llm seam, and saves the default for new sessions via ctx.agentDefaultModel; and a standalone CLI that probes OpenAI-compatible /models endpoints for reachability, HTTP status, latency, model count, and credential configuration. Use it for route health observation and default model switching. Caveat: a successful /models response confirms endpoint reachability only, not end-to-end generation correctness, and switching affects new sessions only.

dsh-switch 是 DeepSeek Harness 的证据优先模型控制平面插件。它提供两个功能:在 DSH 会话中通过 ctx.llm 与 ctx.agentDefaultModel 检视、校验并保存新会话的默认 provider/model;独立 CLI 通过 OpenAI 兼容的 /models 端点探测可达性、HTTP 状态、延迟、模型数量与凭据配置。适用于路由健康观察与默认模型切换。注意:探测仅验证端点可达性,不证明端到端生成正确性;切换仅影响新会话,现有会话保留原路由。

Evidence-first model control plane for DeepSeek Harness.

中文

dsh-switch does two deliberately separate jobs:

  1. The DSH bundle exposes model-facing tools that inspect registered provider routes, validate an exact provider/model through the official ctx.llm seam, and save the default for new sessions through ctx.agentDefaultModel.
  2. The standalone CLI probes OpenAI-compatible /models endpoints and reports reachability, HTTP status, latency, model count, and whether a credential environment variable is configured.

It does not intercept model requests, implement another OpenAI adapter, or silently reroute an active session. Projects such as dsh-polyglot and dsh-llm-fallbacks own adapter/fallback behavior; this project is the observable control plane around routes DSH already knows.

Install the DSH bundle

Pin a reviewed commit when installing from GitHub:

dsh plugin --profile web add github:dongsheng123132/dsh-switch#<commit>
dsh --profile web --dump-config

The bundle ships JavaScript and has no install/build lifecycle script.

Tools

dsh_switch_status({ includeModels? })

  • shows the default selection used by newly created sessions;
  • lists registered provider routes;
  • optionally asks each adapter for its advertised models;
  • performs no provider network health request itself.

dsh_switch_default({ provider, model, reasoningEffort?, expectedProvider?, expectedModel? })

  • validates the exact route with ctx.llm.resolveModelInfo();
  • rejects an unsupported reasoning effort;
  • supports an optimistic-concurrency expectation pair;
  • saves through ctx.agentDefaultModel.saveSelection();
  • reads the value back and fails if the write is not observable;
  • affects new sessions only. Existing sessions keep the route recorded in their logs.
