Windows: npm global install creates broken shims that reference /bin/sh

[orro3790]

Description

When installing agent-browser globally on Windows via npm install -g agent-browser, the generated shims (.ps1 and .cmd) fail because they reference /bin/sh which doesn't exist on Windows.

Steps to Reproduce

1. On Windows, run: npm install -g agent-browser
2. Run: agent-browser open https://example.com

Expected Behavior

The command should work, using the native Windows binary (agent-browser-win32-x64.exe).

Actual Behavior

PowerShell error:

& "/bin/sh.exe" ...
The term '/bin/sh.exe' is not recognized as a name of a cmdlet, function, script file, or executable program.

CMD error:

The system cannot find the path specified.

Root Cause

The generated shims in %APPDATA%\npm\ point to the shell script wrapper instead of the native Windows binary:

agent-browser.ps1 tries to run:

& "/bin/sh$exe" "$basedir/node_modules/agent-browser/bin/agent-browser" $args

agent-browser.cmd tries to run:

SET "_prog=/bin/sh"

Workaround

Manually overwrite the shims to use the native binary:

agent-browser.cmd:

@ECHO off
"%~dp0\node_modules\agent-browser\bin\agent-browser-win32-x64.exe" %*

agent-browser.ps1:

#!/usr/bin/env pwsh
$basedir = Split-Path $MyInvocation.MyCommand.Definition -Parent
& "$basedir\node_modules\agent-browser\bin\agent-browser-win32-x64.exe" $args
exit $LASTEXITCODE

Suggested Fix

Update package.json bin field to properly handle Windows, either by:

1. Using a cross-platform bin wrapper that detects the OS and runs the appropriate binary
2. Using npm's platform-specific bin configuration

Environment

• OS: Windows 11
• Node.js: v22.20.0
• npm: (global install)
• agent-browser: 0.6.0
