Install

Start with a prompt that asks an agent to read the source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to read the page and repository first.

Do not install anything yet. Read this DeepSeek Harness plugin and explain what it does, which files, networks, or credentials it can access, and how to install and remove it.

dsh-langfuse-plus

DSH（DeepSeek Harness）的 Langfuse 可观测性插件：会话轮次映射为 Langfuse trace 树（同会话经 session id 聚合），提供 Prompt 版本管理与评测能力。

  • 零 DSH 源码修改，基于官方 telemetry seam
  • turn/step/tool/generation/event 全映射，含 token 用量
  • system prompt 与 Langfuse 版本化双向同步
  • /feedback 自动上报 score、/dataset 一键建评测数据集
  • DSH 侧栏一键跳转 Langfuse

安装

export DSH_LANGFUSE_PUBLIC_KEY=lf_pk_...
export DSH_LANGFUSE_SECRET_KEY=lf_sk_...

# npm 安装
dsh plugin --profile web add dsh-langfuse-plus

# 或本地目录安装（开发）
dsh plugin --profile web add ./dsh-langfuse-plus

配置项（实例地址 / 环境标签 / Prompt 同步等）见 [.env.example](.env.example)，均可用环境变量覆盖。自托管 Langfuse 编排见 [docker-compose.langfuse.yml](docker-compose.langfuse.yml)。

需 DSH ≥ 0.1.0-rc.6（rc.8 已验证兼容）与 Langfuse ≥ v4。

限制

  • 未挂脱敏规则时，会话数据原样透传至 Langfuse（脱敏需自行挂 session-telemetry/record 监听器）
  • 成本由 Langfuse 按模型价格表计算（Settings → Model Definitions 配置 DeepSeek 价格后显示），插件不上报价格
  • 进程被 SIGKILL（未走 shutdown 兜底）时，内存中最后一批 span 可能丢失
