code-simplification

Code simplification reduces unnecessary complexity in functional code to improve readability and maintainability while preserving exact input, output, and error behavior. It validates changes incrementally by running tests to prevent regressions.

The best way to clean up deeply nested conditionals is behavior-preserving refactoring that consolidates duplicated logic and flattens structures. This ensures the code remains understandable to new team members without altering existing functionality.

To simplify code written under time pressure without breaking tests, apply incremental changes scoped to recently modified code. This enforces behavior preservation and validates every refactoring step through continuous test runs.

Yes, you can refactor code to match project conventions by aligning naming, style, and error handling patterns. This limits modifications to what is necessary for consistency, avoiding unnecessary churn across the codebase.

You should not use code simplification when working code lacks test coverage, as the process relies on incremental test validation to enforce exact behavior preservation. Scoping changes to recently modified code is necessary to prevent regressions.
