DeepSeek Harness 的 provider fallback chain 插件:主 provider 失败时,同一个请求会自动在下一个配置的 (provider, model) 目标上重试,限流、超时或临时不可用的 provider 不再直接终结一轮对话。

DeepSeek Harness dsh-plugin 生态的社区插件,不属于官方仓库。

当前插件版本 0.2.0,兼容 DeepSeek Harness 0.2.0-rc.2(peerDependencies 对齐该版本,cordis ~4.0.4、schemastery ~3.18.4;未在其他 dsh 版本上验证)。

功能与行为

  • 请求本身永远是链头(UI 里选的 provider/model,或部署默认值),插件绝不改写它;只有失败重试才会切到备用目标。
  • 失败请求按顶层 fallbacks 顺序切换,最后一个备用目标不再切换,其失败按正常方式上抛。
  • 按链头/备用目标的连续可切换失败计数打开熔断;冷却期内每个请求仍先试链头,探测失败则无条件再次切换。
  • 无备用目标时插件保持休眠,所有请求原样放行;保存第一个目标后在下一次请求生效,无需重启。
  • 每次切换、以及每次实际由备用目标服务的请求,都会写入持久会话事件(模型不可见)。
  • 与 base bundle 自带的 @deepseek-ai/dsh-llm-retry 按 waterfall 顺序组合,只需挂 llm-fallback 一条,不要重复挂 llm-retry。

完整路由语义、字段规则与事件载荷见技术参考。

安装与最短可用配置

dsh plugin --profile web add @visol-456/dsh-llm-fallback

本包声明了 dsh.bundle,安装后会作为 profile 层自动激活;随包的 cordis.patch.yml 以无备用目标挂载插件(休眠状态)。装好后在 Web 界面创建备用目标即可:

侧边栏 Plugins → Installed 列表里的 llm-fallback 卡片 → 打开卡片页 → 用 provider/model 下拉框添加备用目标,调整切换错误码/失败阈值/冷却时间 → 保存。

如需手动挂载或通过 cordis.yml 配置,请看技术参考。

插件页能力

  • 备用目标逐行编辑:provider/model 联动下拉、行内上移/下移/删除;provider 下拉只列出 harness 模型目录里真实可用且已加载 model 列表的路由,并按展示名显示。
  • 切换错误码(宽输入框)、失败阈值、冷却时间在同一表单内编辑;保存写入当前 profile 的条目配置,并在下一次请求生效。
  • 恢复默认值清除表单保存的四个字段,回到组合层与 schema 默认行为。
  • 若配置在别处被修改,页面显示冲突横幅,提示先重新加载再重新应用。
