System prompt suggests Linux-specific commands on Windows platforms

[Thomas-Shephard]

What happened?

When running Gemini CLI on Windows, the system prompt provided to the model contained Linux-specific command examples (like grep, tail, and head) and used the && operator for command chaining. This caused the agent to suggest commands that failed to execute or were not idiomatic for a Windows environment (Cmd/PowerShell), hindering the user experience and task automation.

What did you expect to happen?

The system prompt should be platform-aware. When running on Windows, it should provide PowerShell-equivalent commands (e.g., Select-String, Get-Content -Tail) and use compatible command separators (;) to ensure suggested information-gathering commands work correctly.
