调研方向

The report identifies the terminal tool's use of cmd.exe on Windows and requests PowerShell by default, with optional shell selection. Start by locating how the desktop app launches its terminal tool and how it selects a shell on Windows. Done means the tool uses the expected shell and the reproduction command behaves as expected; the issue does not name files or tests.

描述

bug p1
GUI version

0.1.56

Operating system

Windows

Reproduction steps
  1. let AI run this command: echo "SHELL=$SHELL"
  2. See terminal printing the string literally, including the "
Expected behavior

Use powershell (and pwsh when possible) for terminal tool. Would be even better if user can choose which one to use (powershell/pwsh/git-bash)

Actual behavior

Terminal tool using cmd.exe

Screenshots, recordings, or sanitized logs

AI report:

## The active shell for `shell_command`: **cmd.exe**
`C:\WINDOWS\system32\cmd.exe`

**Evidence (each probe independently rules the others out):**
| Probe | Result | Meaning |
|---|---|---|
| `echo %COMSPEC%` | `C:\WINDOWS\system32\cmd.exe` | cmd-style `%VAR%` expansion; PowerShell/bash would leave it literal |
| `echo "SHELL=$SHELL"` | printed the string **literally** | no `$VAR` expansion → not bash, not PowerShell |
| `ver` | `Microsoft Windows [version 10.0.26300.9711]` | cmd's built-in banner |
| `&` / `&&` chaining | worked | cmd command separator semantics |
| `powershell` tool parent process | `C:\WINDOWS\system32\cmd.exe` | the harness spawns cmd.exe, which then invokes PowerShell |

## The other three candidates — all present, none active
- **Windows PowerShell 5.1 (Desktop)** — `C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe`, v5.1.26100.9711, CLR 4.0.30319. This is what the dedicated `powershell` tool runs (child of cmd.exe).
- **PowerShell 7 (`pwsh`)** — `C:\Users\XXX\AppData\Local\Microsoft\WindowsApps\pwsh.exe`, reports `Core 7.6.7`. Store app-execution-alias install, on PATH but not the shell in use.
- **Git Bash** — `C:\Program Files\Git\bin\bash.exe` exists (MSYS2/MINGW64, `MINGW64_NT-10.0-26300`, bash 3.6.10), but `C:\Program Files\Git\bin` is **not in PATH**, so `where bash` fails. Callable by absolute path only.

**Bottom line:** the terminal is **cmd.exe**. For richer scripting use the `powershell` tool (5.1 Desktop) or invoke `pwsh` for PowerShell 7.
