This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and 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 review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

DeepSeek Harness 插件:一键安装「极简模式 (Git Bash)」agent preset —— 把 DSH 自带极简模式中的 bash 调用映射到 Git for Windows 的 bash(MSYS),让 Windows 上的极简模式真正可用。

About

DSH 自带的极简模式在 Windows 上无法使用,失败有两层原因:

1. PTY 平台限制:极简模式的持久 bash 依赖 PTY 后端,而 @deepseek-ai/dsh-subprocess-local 在 win32 上直接拒绝(terminal inspection is unsupported on platform win32),与 bash 是否存在无关; 2. shell 缺失:即便绕过 PTY,@deepseek-ai/dsh-bash-local 硬编码从 PATH 找 bash,Windows 上默认没有。

本插件交付一个可安装的预设变体:同一套极简 persona + str_replace_editor 双工具表面,但 bash 工具每次命令执行 <git bash> -c <command>,并通过沙箱感知门控保证不绕过安全边界。

特性

  • 幂等安装:插件启动时把打包的预设复制到用户预设根(${DSH_HOME:-~/.dsh}/.agent-presets/minimal-gitbash/),已存在则跳过,force: true 才覆盖;
  • 自动探测 bashGIT_BASH 环境变量 → 常见安装目录(ProgramFiles / ProgramFiles(x86) / LOCALAPPDATA)→ PATH 中的 bash.exe → 兜底 bash,无需硬编码路径;
  • 沙箱感知门控:MSYS 运行时无法在 Windows 受限令牌沙箱内启动(无法创建 signal pipe),因此命令仅在"完全访问"策略下执行——不绕过沙箱,受限时给出明确升级指引;
  • 极简不变:固定 persona、str_replace_editor、无上下文压缩,与原极简模式一致。

工作原理

环节说明
插件行cordis.patch.yml 在 web profile 组合中插入 dsh-gitbash-preset,启动时安装预设文件
预设组合agent.cordis.ymlgitbash-shell 组以 entry-local realm 提供 shell 服务,tool-bash 注册模型工具
执行器gitbash-executor.mjs 通过 host 的 subprocess 服务执行 bash -c,处理超时、后台、输出截断与错误诊断
沙箱门控run/start 校验策略:仅 danger-full-access(或部署无沙箱)放行,否则抛出带指引的错误

安装

dsh plugin --profile web add @icelily/dsh-gitbash-preset

或手动合并 cordis.patch.yml 到 profile patch 层。重启 DSH 后生效;重启后插件会自动安装预设(已存在则 no-op,不会覆盖你已有的版本)。

也可以不装插件,直接把 agent-presets/minimal-gitbash/ 目录复制到 ~/.dsh/.agent-presets/

使用

1. Web 界面新建会话,选择 极简模式 (Git Bash); 2. 二选一启用 bash: - 把会话沙箱切到完全访问,之后所有 bash 调用直接走 git bash; - 或保持 workspace-write,让模型在第一次调用失败后按提示用 sandbox_permissions: "danger-full-access" + justification 单次升级(走正常审批流程)。

配置

预设配置agent-presets/minimal-gitbash/agent.cordis.ymlgitbash-executor):

字段默认说明
shellPath自动探测显式指定时优先(如 'C:\\Program Files\\Git\\bin\\bash.exe'
timeoutMs120000单次命令默认超时(上限 maxTimeoutMs
maxTimeoutMs600000超时上限
maxOutputBytes64000单流保留字节数(溢出写入 spill 文件)
graceMs3000终止进程的 SIGTERM→SIGKILL 宽限

插件配置cordis.patch.yml 插入行):

字段默认说明
forcefalse预设已存在时是否用包内文件覆盖(保留用户额外文件)

开发

npm run check   # 三个文件语法检查(插件、执行器、测试)
npm run test    # 单元测试:路径转换 / 探测优先级 / 配置校验,10 个用例

限制

  • 会话沙箱为 workspace-write(或更窄)时,git bash 无法启动(MSYS 受限令牌限制),需切换完全访问或单次升级——这是沙箱边界,插件不绕过;
  • 与原极简模式不同,bash 为每次调用新 shell(不保持 cd/export 状态)——Windows 上 PTY 持久会话不可用,此为替代设计。
