async handle_tool_call(func_name: str, func_args: Dict[str, Any], session_id: str | None = None) → Tuple[Any, bool, bool]

Handle a built-in Qveris tool call from an LLM response.

• Parameters:
  • func_name – The name of the function/tool to call
  • func_args – The arguments parsed from the LLM response
  • session_id – Optional session ID for tracking
• Returns:
  • result: the tool output (None if not handled)
  • is_error: True if an error occurred
  • handled: True if this was a Qveris tool and was processed
• Return type: Tuple of (result, is_error, handled) where

Notes

• params_to_tool may be either a dict (canonical) or a JSON string (legacy).
• If func_name is not a Qveris built-in, (None, False, False) is returned so that callers can route to their own tool handlers.
