Add Backend Tool

Instructions

Read backend/main.py to understand existing tool patterns:
- Find the tools list with function definitions
- Review helper functions (read_file, write_file, run_terminal_command, web_search)

Create the helper function:

def new_tool_name(param1: str, param2: int = 10) -> str:
    """Docstring explaining the tool."""
    try:
        # Implementation
        return result
    except Exception as e:
        return f"Error: {str(e)}"

Add tool definition to the tools list:

{
    "type": "function",
    "function": {
        "name": "new_tool_name",
        "description": "What this tool does and when to use it",
        "parameters": {
            "type": "object",
            "properties": {
                "param1": {"type": "string", "description": "..."},
                "param2": {"type": "integer", "description": "..."}
            },
            "required": ["param1"]
        }
    }
}

Add tool invocation handler in the WebSocket message loop:

elif func_name == "new_tool_name":
    result = new_tool_name(**args)

Update mode restrictions if needed:
- Agent mode: full access
- Chat mode: add to allowed list only if read-only/safe

Examples

"Add a tool to list directory contents"
"Create a tool for git operations"
"Add web scraping capability"

Guardrails

Include proper error handling with try/except
Add timeout for any long-running operations
Consider security implications (Chat mode restrictions)
Never hardcode API keys or secrets
Document the tool's purpose in the function docstring
