Currently, how the exceptions are handled depends largely on the code execution flow of the project. The best practices for handling these exceptions, including VariableNotFoundError, would involve encapsulating the code block where an error could potentially occur in a try/catch block and dealing with exceptions as they arise.

To provide more detailed error information, for instance, specifying the variable that was not found, the VariableNotFoundError could potentially have a message property that contains information about the variable. This would allow developers to write more detailed and helpful error messages. For example:

from automata.eval.code_writing_eval import VariableNotFoundError

try:
    # Hypothetically, "code_execution_function" is a function where the code execution takes place.
    code_execution_function()
except VariableNotFoundError as error:
    print(f"Variable '{error.variable_name}' not found. Please check.")

# Prints out: "Variable 'example_variable' not found. Please check."

In this case, the VariableNotFoundError would need to be defined with an additional variable_name property:

class VariableNotFoundError(AutomataError):
    def __init__(self, variable_name):
        self.variable_name = variable_name
        super().__init__(f"Variable '{self.variable_name}' not found.")

However, this kind of modification would need to be considered carefully based on the overall design of the Automata system and its exception handling strategy.
