Replace verbose, complex code structures with simpler, more readable alternatives. Prefer existing methods over inline complex logic, use built-in functions instead of manual implementations, and leverage modern Python features for cleaner code. Examples of improvements: - Replace complex conditionals with existing methods: `if browser_session.is_file_input(element_node):` instead of multi-line type checking - Simplify string manipulation: `script_content.replace('```python', '').replace('```', '')` instead of complex split logic with potential IndexError - Use dictionary dispatch instead of long if/elif chains for action mapping - Leverage modern Python features like the walrus operator: `if (last_action := self.step_results[-1]['actions'][-1])['is_done']` This approach reduces code complexity, improves maintainability, and makes the codebase more readable while preventing potential errors from overly complex implementations.
