Error Logs

Additional Context

Per codemie-opencode investigation:

Root Cause

In shell-hooks-source.js:233, the execCommandAsync() function spawns sh.exe directly without windowsHide: true:

const child = spawn("sh", ["-c", command], {
    env: { ...process.env, ...env },
    stdio: ["pipe", "ignore", "ignore"],
    detached: true,
    // ❌ missing: windowsHide: true
});

The detached: true option prevents the child from being attached to the parent console, but on Windows it does not suppress the creation of a new console window for the detached process. The windowsHide: true option is required to prevent the console window from appearing.

Additional Context

• The synchronous execCommand() at line 210 also uses execSync() without windowsHide (Node.js 16+ supports windowsHide on execSync), though execSync typically inherits the parent hidden window when the parent was spawned with windowsHide: true.
• The utils/exec.js utility (line 48) already correctly passes windowsHide: true.
• The main process spawn in BaseAgentAdapter.js:749 already passes windowsHide: true.

Environment

• OS: Windows
• Git Bash provides the sh.exe binary
• Codemie version: 0.14.0

Fix

Add windowsHide: true to the spawn options in execCommandAsync():

const child = spawn("sh", ["-c", command], {
    env: { ...process.env, ...env },
    stdio: ["pipe", "ignore", "ignore"],
    detached: true,
    windowsHide: true,  // ✅ suppress console window
});

Hi @Feoni4 ! I'd like to work on this issue.

I've reviewed the reported root cause and confirmed that execCommandAsync() spawns sh with detached: true but without windowsHide: true.

I plan to add windowsHide: true to the async spawn options and include a regression test to make sure the option remains enabled.

Please let me know if you'd prefer a different approach. Thanks!
