SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audit a codebase to identify handcrafted code that duplicates functionality already provided by dependencies, then propose refactoring plans that remove duplication while preserving behavior.

Core Features & Use Cases

  • Identifies duplicated utilities and patterns across a project and suggests library-based replacements.
  • Evaluates feasibility of replacement, checks API compatibility, and outlines a structured refactor plan.
  • Use Case: A monorepo contains several small utility functions duplicating lodash or commons; refactorlib suggests replacing with existing dependencies.

Quick Start

Run the audit to generate a structured replacement plan for a given project, focusing on duplications and dependency opportunities.

FAQPage Schema
How do I find duplicated code in a project that already exists in dependencies?

To find duplicated code that overlaps with dependencies, run an audit to identify handcrafted patterns across modules and map them to existing library functions. The audit evaluates replacement feasibility and API compatibility to ensure the suggested library substitutions match your current implementation.

What is the best way to audit a codebase for refactoring opportunities without breaking behavior?

The best way to audit a codebase for refactoring safely is to generate a structured plan that identifies duplication, evaluates dependency API compatibility, and outlines guardrails. This approach proposes replacements without executing changes, preventing unintended behavioral shifts during the actual codebase refactor.

Can I automatically replace handcrafted utilities with existing dependencies?

You cannot automatically replace handcrafted utilities with dependencies using this approach. It identifies duplications and evaluates API compatibility to produce a structured refactoring plan, but it does not execute code changes, ensuring you maintain manual control over the final dependency integration.

How do I plan a refactoring strategy for a monorepo with duplicated utility functions?

To plan a refactoring strategy for a monorepo with duplicated utilities, audit the project to prioritize modules duplicating dependency functionality. The output is a structured plan detailing expected impact, specific replacements, and guardrails to avoid breaking behavior across the interconnected packages.

What are the limitations of auditing code for dependency replacements?

A limitation of auditing code for dependency replacements is that it only produces a structured plan and does not execute the refactoring. You must manually apply the suggested changes, verify API compatibility, and follow the provided guardrails to ensure the behavior remains unchanged.
