What steps do you take to prevent errors from appearing at the very beginning of task execution?

To prevent errors at the beginning of a task, I usually take the following steps:

• Carefully study the requirements and the task — clarify any unclear points with the customer or team.
• Plan the solution — break the task into subtasks, think through the architecture and logic.
• Write tests or check the possibility of writing them — this helps to immediately identify discrepancies.
• Use static analysis and linters — to catch syntactic and stylistic errors.
• Check the environment and dependencies — to ensure all necessary components are ready for work.

This approach helps minimize errors and improve code quality from the very beginning.
