kimi-cli Feature Request: 支持 PowerShell 7 (pwsh) 作为 Windows 默认 Shell

问题描述

在 Windows 环境下，kimi-cli 的 Shell 工具硬编码使用 Windows 自带的 PowerShell 5.1 (C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe)，完全忽略用户可能已安装的 PowerShell 7 (pwsh)。

这导致即使用户终端默认使用 PowerShell 7.6.1，kimi-cli 的 Shell 工具仍然调用 5.1 执行命令。

复现步骤

1. 在 Windows 上安装 PowerShell 7 (pwsh)
2. 确保 pwsh 在 PATH 中可用
3. 启动 kimi 并执行任意 Shell 命令
4. 观察实际执行环境：

   $PSVersionTable.PSVersion  # 返回 5.1.x，而非 7.x
   

预期行为

kimi-cli 在 Windows 上应该优先检测 pwsh.exe（PowerShell 7），如果存在则使用它；仅在没有 pwsh 的情况下 fallback 到 PowerShell 5.1。

实际行为

kimi-cli 直接硬编码指向 PowerShell 5.1 的路径，完全不检查 pwsh：

# kimi_cli/utils/environment.py (原始代码)
if os_kind == "Windows":
    shell_name = "Windows PowerShell"
    system_root = os.environ.get("SYSTEMROOT", r"C:\Windows")
    possible_paths = [
        KaosPath(
            os.path.join(
                system_root, "System32", "WindowsPowerShell", "v1.0", "powershell.exe"
            )
        ),
    ]

影响

• PowerShell 7 用户无法利用 PS7 的新特性（如 ForEach-Object -Parallel、改进的 UTF-8 默认处理、跨平台模块等）
• 用户终端环境和 kimi-cli 执行环境不一致，导致行为差异
• 配置文件 (config.toml) 中没有任何选项可以自定义 shell 路径或名称

建议方案

方案 A：自动检测 pwsh（推荐）

修改 kimi_cli/utils/environment.py，在 Windows 分支中优先通过 shutil.which("pwsh") 检测 PowerShell 7：

  import os
  import platform
+ import shutil
  from dataclasses import dataclass
  from typing import Literal

  @dataclass(slots=True, frozen=True, kw_only=True)
  class Environment:
      os_kind: Literal["Windows", "Linux", "macOS"] | str
      os_arch: str
      os_version: str
-     shell_name: Literal["bash", "sh", "Windows PowerShell"]
+     shell_name: Literal["bash", "sh", "Windows PowerShell", "pwsh"]
      shell_path: KaosPath

      @staticmethod
      async def detect() -> Environment:
          # ... 平台检测逻辑 ...

          if os_kind == "Windows":
-             shell_name = "Windows PowerShell"
-             system_root = os.environ.get("SYSTEMROOT", r"C:\Windows")
-             possible_paths = [
-                 KaosPath(
-                     os.path.join(
-                         system_root, "System32", "WindowsPowerShell", "v1.0", "powershell.exe"
-                     )
-                 ),
-             ]
-             fallback_path = KaosPath("powershell.exe")
-             for path in possible_paths:
-                 if await path.is_file():
-                     shell_path = path
-                     break
-             else:
-                 shell_path = fallback_path
+             # 优先检测 PowerShell 7 (pwsh)
+             pwsh_exe = shutil.which("pwsh")
+             if pwsh_exe:
+                 shell_name = "pwsh"
+                 shell_path = KaosPath(pwsh_exe)
+             else:
+                 shell_name = "Windows PowerShell"
+                 system_root = os.environ.get("SYSTEMROOT", r"C:\Windows")
+                 possible_paths = [
+                     KaosPath(
+                         os.path.join(
+                             system_root, "System32", "WindowsPowerShell", "v1.0", "powershell.exe"
+                         )
+                     ),
+                 ]
+                 fallback_path = KaosPath("powershell.exe")
+                 for path in possible_paths:
+                     if await path.is_file():
+                         shell_path = path
+                         break
+                 else:
+                     shell_path = fallback_path

同时修改 kimi_cli/tools/shell/__init__.py，让 pwsh 也被识别为 PowerShell：

      def __init__(self, approval: Approval, environment: Environment, runtime: Runtime):
-         is_powershell = environment.shell_name == "Windows PowerShell"
+         is_powershell = environment.shell_name in ("Windows PowerShell", "pwsh")
          super().__init__(...)

方案 B：配置文件支持（更灵活）

在 config.toml 中增加 shell 配置项：

[shell]
name = "pwsh"           # 或 "bash", "zsh", "Windows PowerShell"
path = "D:\\forsoft\\PowerShell7\\pwsh.exe"  # 可选，留空则自动检测

这样所有平台用户都可以自定义 shell，不仅限于 Windows PowerShell 7 用户。

环境信息

• OS: Windows 11
• kimi-cli version: 1.38.0 (通过 uv 安装)
• PowerShell 7 安装路径: D:\forsoft\PowerShell7\pwsh.exe
• pwsh 已在 PATH 中可用

备注

目前 config.toml 的配置结构 (kimi_cli/config.py 中的 Config 类) 没有任何与 shell 相关的字段，说明 shell 选择从未被设计为可配置项。希望官方能考虑支持，这对 Windows 开发者体验很重要。

kimi-cli Feature Request: Support PowerShell 7 (pwsh) as Windows default shell

Problem description

In a Windows environment, the Shell tool of kimi-cli is hard-coded to use the PowerShell 5.1 that comes with Windows (C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe), completely ignoring the PowerShell 7 (pwsh) that the user may have installed.

This causes the kimi-cli Shell tool to still call 5.1 to execute commands even if the user terminal uses PowerShell 7.6.1 by default.

Reproduction steps

1. Install PowerShell 7 (pwsh) on Windows
2. Make sure pwsh is available in PATH
3. Start kimi and execute any shell command
4. Observe the actual execution environment:

   $PSVersionTable.PSVersion # returns 5.1.x, not 7.x
   

expected behavior

kimi-cli on Windows should preferentially detect pwsh.exe** (PowerShell 7) and use it if present; only fallback to PowerShell 5.1 if pwsh is not available.

Actual behavior

kimi-cli directly hardcodes the path to PowerShell 5.1, without checking pwsh at all:

# kimi_cli/utils/environment.py (original code)
if os_kind == "Windows":
    shell_name = "Windows PowerShell"
    system_root = os.environ.get("SYSTEMROOT", r"C:\Windows")
    possible_paths = [
        KaosPath(
            os.path.join(
                system_root, "System32", "WindowsPowerShell", "v1.0", "powershell.exe"
            )
        ),
    ]

Impact

• PowerShell 7 users cannot take advantage of new PS7 features (such as ForEach-Object -Parallel, improved UTF-8 default handling, cross-platform modules, etc.)
• The user terminal environment and the kimi-cli execution environment are inconsistent, resulting in behavioral differences
• There is no option in the configuration file (config.toml) to customize the shell path or name

Suggestions

Solution A: Automatically detect pwsh (recommended)

Modify kimi_cli/utils/environment.py to preferentially detect PowerShell 7 through shutil.which("pwsh") in the Windows branch:

  import os
  import platform
+ import shutil
  from dataclasses import dataclass
  from typing import Literal

  @dataclass(slots=True, frozen=True, kw_only=True)
  classEnvironment:
      os_kind: Literal["Windows", "Linux", "macOS"] | str
      os_arch: str
      os_version: str
- shell_name: Literal["bash", "sh", "Windows PowerShell"]
+ shell_name: Literal["bash", "sh", "Windows PowerShell", "pwsh"]
      shell_path: KaosPath

      @staticmethod
      async def detect() -> Environment:
          #...Platform detection logic...

          if os_kind == "Windows":
- shell_name = "Windows PowerShell"
- system_root = os.environ.get("SYSTEMROOT", r"C:\Windows")
- possible_paths = [
-KaosPath(
- os.path.join(
- system_root, "System32", "WindowsPowerShell", "v1.0", "powershell.exe"
- )
- ),
- ]
- fallback_path = KaosPath("powershell.exe")
- for path in possible_paths:
- if await path.is_file():
- shell_path = path
- break
-else:
- shell_path = fallback_path
+ # Prioritize detection of PowerShell 7 (pwsh)
+ pwsh_exe = shutil.which("pwsh")
+ if pwsh_exe:
+ shell_name = "pwsh"
+ shell_path = KaosPath(pwsh_exe)
+ else:
+ shell_name = "Windows PowerShell"
+ system_root = os.environ.get("SYSTEMROOT", r"C:\Windows")
+ possible_paths = [
+ KaosPath(
+ os.path.join(
+ system_root, "System32", "WindowsPowerShell", "v1.0", "powershell.exe"
+ )
+ ),
+ ]
+ fallback_path = KaosPath("powershell.exe")
+ for path in possible_paths:
+ if await path.is_file():
+ shell_path = path
+ break
+ else:
+ shell_path = fallback_path

Also modify kimi_cli/tools/shell/__init__.py so that pwsh is also recognized as PowerShell:

      def __init__(self, approval: Approval, environment: Environment, runtime: Runtime):
- is_powershell = environment.shell_name == "Windows PowerShell"
+ is_powershell = environment.shell_name in ("Windows PowerShell", "pwsh")
          super().__init__(...)

Option B: Configuration file support (more flexible)

Add the shell configuration item in config.toml:

[shell]
name = "pwsh" # or "bash", "zsh", "Windows PowerShell"
path = "D:\\forsoft\\PowerShell7\\pwsh.exe" # Optional, leave blank to automatically detect

This allows users on all platforms to customize their shells, not just Windows PowerShell 7 users.

Environment information

• OS: Windows 11
• kimi-cli version: 1.38.0 (installed via uv)
• PowerShell 7 installation path: D:\forsoft\PowerShell7\pwsh.exe
• pwsh is already available in PATH

Remarks

The current configuration structure of config.toml (the Config class in kimi_cli/config.py) does not have any shell related fields, indicating that the shell selection was never designed to be configurable. I hope the official can consider supporting it, which is very important for the Windows developer experience.

Additional information

No response

Start with kimi_cli/utils/environment.py and trace Environment.detect() through the Windows shell selection, then inspect kimi_cli/tools/shell/init.py for PowerShell-specific handling. Verify the recommended pwsh-first behavior when pwsh is on PATH and the existing Windows PowerShell fallback when it is absent; the issue does not name a test file.
