🛡️ Safety

Before executing any generated command, the agent:

• Validates the generated PowerShell command
• Blocks potentially unsafe commands (based on validator rules)
• Requests user confirmation before execution

This helps prevent accidental execution of harmful commands.

---

📌 Current Limitations

• Supports Windows PowerShell only
• Requires a Google Gemini API key
• Executes one command at a time
• Does not maintain conversation memory between commands

---

🚀 Future Improvements

• Conversation memory
• LangGraph integration
• Tool calling
• Command history
• Plugin support
• Persistent shell session
• Linux and macOS support
• Rich terminal interface
