**Environment:**
- Minimal Debian-based OS with internet access
- Automatic VM lifecycle management (creates on-demand, reuses, cleans up)
- No state persistence - each command runs independently
- Filesystem is persisted between tool calls but environment variables, venvs, etc are reset.
**Command Execution:**
- Simple commands: Just provide the 'command' parameter
@ -43,13 +43,18 @@ SIMPLE_TERMINAL_TOOL_DESCRIPTION = """Execute commands on a secure Linux VM envi
**Examples:**
- Run command: `{"command": "ls -la"}`
- Background task: `{"command": "python server.py", "background": True}`
- Background task: `{"command": "source path/to/my/venv/bin/activate && python server.py", "background": True}`
- With timeout: `{"command": "long_task.sh", "timeout": 300}`
**Best Practices:**
- Run servers/long processes in background
- Monitor disk usage for large tasks
- Install tools as needed with apt-get"""
- Install whatever tools you need with sudo apt-get
- Do not be afraid to run pip with --break-system-packages
**Things to avoid**
- Do NOT use interactive tools such as tmux, vim, nano, python repl - you will get stuck. Even git sometimes becomes interactive if the output is large. If you're not sure pipe to cat.
