DeepSeek Harness 每轮失败排查

<role>会话里每次发送都立刻失败、连模型都没请求时,先从会话日志拿到真实错误,再修 profile 补丁配置。</role>

Steps

  1. 找最近会话日志:%USERPROFILE%\.dsh\sessions\<工作区目录>\<session-id>\session.v4.jsonl.zstd,按修改时间取最新。
  2. 解压并只看每轮的结局(日志是 zstd 流,帧头可能没有 content size,必须用 stream_reader):
import zstandard, json
p = r"...\session.v4.jsonl.zstd"
with open(p, "rb") as f:
    data = zstandard.ZstdDecompressor().stream_reader(f).read().decode("utf-8")
for line in data.splitlines():
    e = json.loads(line)
    if e.get("type") == "turn/end":
        print(e["data"]["turn"], e["data"]["reason"])
  1. 若错误是 unknown prompt variable "{{x}}" in section "deployment:persona-suffix"; registered variables: provider, model,去改 %USERPROFILE%\.dsh\profiles\desktop\cordis.patch.yml 的 preset-standard → persona。
  2. 改前备份,改后确认 YAML 可解析、文件里不再有非法变量,再让应用重载或重试。

Key Patterns

  • 当前 dsh 版本(0.2.1-rc.2)persona 模板只注册 {{provider}} 和 {{model}};{{cwd}} 不是提示词变量。
  • 当前工作目录由 dsh-working-directory 作为必需的 user-role 上下文注入,内容形如 Current working directory: "<绝对路径>".,不占系统提示词、也不受 includeRuntimeContext: false 影响。
  • 正确写法:persona 只保留合法变量,例如
- id: persona
  name: '@deepseek-ai/dsh-persona'
  config:
    prefix: You are a coding agent powered by the {{model}} model.
  • cwd 只交给 working-directory 上下文;persona 里删掉 suffix: ... {{cwd}} ...,模型仍能从上下文拿到目录。
  • profile 补丁文件受 HMR 监听,保存后通常自动重组;若现有会话仍报同一错误,重启 DeepSeek Harness 再试。
  • 启动期崩溃看 %APPDATA%\@deepseek-ai\dsh-desktop\logs\crash-*-host.log;ECONNREFUSED 127.0.0.1:7890 是本地代理没开,与提示词错误无关。

Notes

  • 先看 turn/end 的 reason.error.message 再动手,以日志里的错误文本为准。
  • 这类错误发生在提示词渲染阶段,换模型、重开会话都无效,必须改配置。
  • 大版本升级后先复查用户补丁里的 {{...}}:只允许当前版本注册过的变量,否则每一轮都会在渲染时失败。
