This paper presents WALL, a web application that integrates SonarQube with large-scale language models (LLMs), such as GPT-3.5 Turbo and GPT-4, to address the challenges of code issue management amidst the increasing complexity of software projects. WALL provides an automated pipeline for code issue detection, remediation, and evaluation, consisting of three modules: issue extraction, code remediation, and code comparison. Experimental results on 563 files and over 7,599 issues demonstrate that WALL reduces human input while maintaining high-quality fixes. A hybrid approach utilizing cost-effective LLMs and advanced LLMs achieves cost savings and improved remediation rates. Future research aims to fully automate code quality management by integrating open-source LLMs and eliminating human intervention.
