SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Refactorer helps developers improve code quality by guiding safe, incremental refactoring without introducing regressions.

Core Features & Use Cases

Guided, step-by-step refactoring workflows
Detect common code smells (long methods, large classes, duplicate code) and propose incremental changes
Ensure tests exist and verify behavior after each change

Quick Start

Provide a small, well-scoped refactor target and let refactorer guide you through the step-by-step execution.

FAQPage Schema

How do I refactor long methods and large classes without breaking existing behavior?▼

Safe code refactoring is achieved by guiding structured edits one change at a time. It ensures tests exist before changes, applies one refactor per step, and validates behavior after each edit to prevent regressions.

What is the best way to start an incremental refactor on a messy codebase?▼

Incremental refactoring starts by providing a small, well-scoped refactor target. The workflow then detects code smells, proposes step-by-step changes, and verifies tests pass after each individual modification.

Can I use this refactoring process with both Python and JavaScript projects?▼

Yes, this refactoring process applies to typical software projects across languages including Python and JavaScript. It guides structured edits safely whenever issues like long methods or duplicate logic are identified.

Do I need to write tests before starting an incremental code refactor?▼

Yes, tests must exist before starting a code refactor. The process ensures tests are present prior to changes and relies on them to validate behavior after each incremental refactoring step.

How does incremental refactoring handle duplicate code logic?▼

Incremental refactoring handles duplicate logic by identifying the code smell and proposing structured edits. It isolates the duplication, applies one safe change at a time, and validates behavior to ensure safe removal.

What are the limitations of step-by-step refactoring for code maintenance?▼

Step-by-step refactoring requires well-scoped targets and existing tests to function safely. It applies changes incrementally, meaning large refactors must be broken down into smaller, validated steps to avoid regressions.
