Understanding LLM Refactoring Capabilities
Large Language Models are demonstrating remarkable potential in automating complex software engineering tasks. Our research highlights their current strengths in executing specified refactorings with high functional correctness, yet reveals significant gaps in autonomously identifying and aligning with human refactoring choices.
The CODETASTE benchmark rigorously evaluates LLM agents on real-world, multi-file code refactorings, going beyond simple syntactic checks to ensure behavior preservation and adherence to human-like structural improvements.
Real-World Applications
From modernizing Go codebases by replacing interface{} with any to restructuring complex Java packages, LLMs can perform substantial, behavior-preserving transformations when given clear instructions. However, in scenarios where agents must independently propose refactorings based on a general problem area, their alignment with human choices drastically reduces.
This suggests a need for more advanced planning capabilities and contextual understanding in autonomous agents to tackle accumulated technical debt effectively.

Case Study: Mockito Refactoring
The Mockito refactoring involved restructuring the org.mockito.internal package into five sub-packages, renaming core classes and methods, and updating all cross-references.
GPT-5.2 (Instructed Track): Achieved a near-perfect IFR of 99%. Successfully used targeted patches and maintained functional correctness.
SONNET 4.5 (Instructed Track): Achieved a perfect IFR of 100%. However, it made extensive use of risky `sed -i` commands, leading to an inconsistent state and build errors.
In Open Track (Direct Mode), both agents struggled, primarily addressing minor nitpicks rather than the broad architectural refactoring demonstrated by the human-authored golden patch.

Your AI Refactoring Roadmap
A phased approach to integrate CODETASTE-driven AI into your development lifecycle, ensuring a smooth transition and measurable impact.
Phase 01: Initial Assessment & Pilot
Conduct a comprehensive codebase analysis to identify refactoring opportunities and technical debt hotspots. Deploy a pilot AI agent on instructed track tasks to validate performance and alignment with human standards.
Phase 02: Strategic Integration
Integrate AI agents into your CI/CD pipeline for automated refactoring suggestions and execution for well-defined tasks. Begin exploring open track capabilities with human oversight to build trust and refine agent performance.
Phase 03: Autonomous Debt Resolution
Empower AI agents to autonomously identify and resolve specific types of technical debt across large codebases. Leverage advanced planning modes (e.g., Oracle Multiplan) to optimize for human-like refactoring decisions.
Phase 04: Continuous Improvement & Expansion
Establish feedback loops to continuously train and improve AI models based on human refactoring decisions. Expand AI-driven refactoring to new projects and deeper levels of architectural optimization.
