dsh-conductor

dsh-conductor 是一个零第三方依赖的 Python 3.13 SDK。它把一段自然语言 prompt 交给工作环境中的 DSH:DSH 负责拆解任务、根据 prompt 选择 Claude Code 或 Codex、通过 tmux 监督执行、独立验证产物,并返回结构化验收结果。

DSH 由运行环境提供,本项目不会安装或调用模型 API。Claude Code 与 Codex 分别由 tmux-claude-code 和 tmux-codex 两个独立 skill 驱动。

SDK 使用

from pathlib import Path

from conductor import Conductor, ConductorConfig

client = Conductor(
    workspace=Path("/path/to/project"),
    config=ConductorConfig(
        # dsh_bin=None 时从 DSH_BIN 或 PATH 查找。
        dsh_bin=None,
        max_attempts=2,
    ),
)

result = client.run(
    """
    请使用 Codex 完成以下任务:创建 hello.txt,内容为 Hello Conductor 加一个换行。

    验收标准:hello.txt 必须存在,且 bytes 恰好等于 b'Hello Conductor\\n'。
    """,
    on_event=lambda event: print(event.format()),
)

print(result.accepted)
print(result.plan.task_summary)
print(result.verdict.summary)

run() 的第一个参数是唯一业务输入。prompt 中可以明确写“使用 Claude Code”或“使用 Codex”;没有明确指定时,DSH 根据任务与当前环境选择。调用方不再传 agent、task 或 verify 参数。

on_event 会在运行中接收 RunEvent,事件来源包括 dsh、claude、codex 和 conductor。事件只用于显示进度,完成事实仍由 DSH 协议、worker receipt 和最终 verdict 文件决定。TaskResult 包含:

  • plan:DSH 生成的 agent、任务摘要、步骤和带 ID 的验收项;
  • verdict:DSH 独立检查后的 accepted/rejected、每项证据、产物和剩余问题;
  • state_directory:本轮 request、plan、task、receipt、verdict 与 worker-screen.log;
  • dsh:协议状态、耗时、事件数量和 DSH 最后文本。

被 DSH 拒绝是正常业务结果,result.accepted 为 False;DSH 启动失败、协议失败或结果文件不合法时抛出 ConductorError。

完整字段、嵌套对象、错误结果和实时事件格式见 docs/result-json.md。可运行示例见 examples/quickstart.py。

CLI

CLI 是 SDK 的薄封装,保留给脚本和人工调用:

python3.13 -m conductor install-skills --workspace /path/to/project
python3.13 -m conductor doctor
python3.13 -m conductor run \
  --workspace /path/to/project \
  --prompt '请使用 Claude Code 创建 hello.txt。验收标准:文件存在且内容为 Hello。'

run 的 stdout 始终只有一个 JSON 对象;实时事件由 CLI 写入 stderr,因此可以安全地重定向 stdout。每次运行启动 DSH 前,SDK 都会把包内两个 skill 直接覆盖到 <workspace>/.dsh/skills/,供 DSH 项目级发现;不会写入 ~/.dsh/skills,任务结束后也不会删除。install-skills --workspace 可提前执行同样的复制操作。show 可读取最近一次运行的 request、用户 prompt、manager prompt、plan、verdict 和日志路径。

.dsh/skills/ 和 .dsh-conductor/ 都是 SDK 生成的运行目录,建议加入项目的 Git 忽略规则。

日志与状态

conductor 会同时轮询两个候选 tmux 会话;DSH 选择哪个 agent 后,只有实际存在的会话产生屏幕日志。默认每 5 秒采样一次,SDK 可通过 ConductorConfig(worker_log_interval_seconds=...) 调整,CLI 可通过 --worker-log-interval-seconds 调整。变化会通过 RunEvent(source="claude"/"codex", kind="worker_output") 回调,并追加到 worker-screen.log。屏幕文字不会被当作完成或验收信号。

状态目录默认位于当前 workspace 下的 .dsh-conductor/;可通过 ConductorConfig(state_dir=...) 或 CLI 的 --state-dir 指定其他位置:

<workspace>/.dsh-conductor/runs/<run-id>/
├── request.json
├── user-prompt.md
├── manager-prompt.md
├── plan.json
├── verdict.json
├── worker-screen.log
└── attempts/
    ├── claude/1/{task.md,receipt.json}
    └── codex/1/{task.md,receipt.json}

每轮运行使用新的 run id 和 receipt token,避免读取旧结论。accepted verdict 必须同时满足 DSH turn/end + session.status=idle、所有验收项通过、产物路径安全且选定 agent 的最终 receipt 有效。

开发验证

python3.13 -m compileall -q conductor skills tests
python3.13 -m unittest discover -v
python3.13 ~/.codex/skills/.system/skill-creator/scripts/quick_validate.py skills/tmux-claude-code
python3.13 ~/.codex/skills/.system/skill-creator/scripts/quick_validate.py skills/tmux-codex

发布

推送 GitHub Release 后,.github/workflows/publish.yml 会先在独立 job 中运行测试并构建 发行包,再用 PyPI Trusted Publishing 上传已验证的 wheel 与 sdist。首次发布前,需要在 PyPI 为 GitHub Actions 配置 Trusted Publisher,并在 GitHub 创建 pypi 环境。完整字段、 版本标签规则和发布步骤见 docs/pypi-publishing.md。
