Terminal Tools Module
Terminal Tool Module
This module provides terminal/command execution tools using Hecate's VM infrastructure.
This module provides a single terminal tool using Hecate's VM infrastructure.
It wraps Hecate's functionality to provide a simple interface for executing commands
on Morph VMs with automatic lifecycle management.
Available tools:
- terminal_execute_tool: Execute a single command and get output
- terminal_session_tool: Execute a command in a persistent session
Available tool:
- terminal_tool: Execute commands with optional interactive session support
Usage:
from terminal_tool import terminal_execute_tool, terminal_session_tool
from terminal_tool import terminal_tool
# Execute a single command
result = terminal_execute_tool("ls -la")
result = terminal_tool("ls -la")
# Execute in a session (for interactive commands)
result = terminal_session_tool("python", input_keys="print('hello')\\nexit()\\n")
# Execute in an interactive session
result = terminal_tool("python", input_keys="print('hello')\\nexit()\\n")
