This issue might be a duplicate of existing issues. Please check:

• Bash tool executes bash commands with cmd.exe #4599: Bash tool executes bash commands with cmd.exe (similar Windows shell execution issue)
• Specific bash commands fail on Windows in Git Bash due to path re-mapping #4379: Specific bash commands fail on Windows in Git Bash due to path re-mapping (Windows path handling)
• Windows Support #631: Windows Support (umbrella issue tracking all Windows problems)
• Opencode bash tool spawn user commands using /bin/sh what is not bash :-) #3479: Opencode bash tool spawn user commands using /bin/sh instead of bash (shell execution configuration)

The core issue appears to be related to how OpenCode spawns shell commands on Windows. When the AI tries to run shell commands on Windows, the spawn mechanism doesn't properly handle bash execution, particularly in WSL environments. Issues #4599 and #4379 describe similar problems where bash-specific commands fail on Windows due to improper shell handling.

Feel free to ignore if none of these address your specific case.

Found out that the shell tool become broken at 1.0.88
1.0.87 is working correctly

@mentalzenith what do you see if you run:
Get-Command bash

or

where bash

PS C:\Windows\system32> Get-Command bash

Asking opencode to run "Get-Command bash" directly gives

# Attempting to run the PowerShell cmdlet Get-Command to locate bash
$ Get-Command bash

Maybe my logic is messed up, but it should only be using bash if you have it in your path, idk why it fails but ill look into it for you
