TL;DR

This paper introduces the Intelligent Code Analysis Agent (ICAA), an AI-driven system combining large language models (LLMs) like GPT-3.5-turbo with engineering workflows to automate detection of code errors and business logic flaws. It achieves a 66% false-positive rate and 60.8% recall, demonstrating significant improvement over traditional methods while highlighting token cost as a key challenge for scalability.

ABSTRACT

The escalating complexity of software systems and accelerating development cycles pose a significant challenge in managing code errors and implementing business logic. Traditional techniques, while cornerstone for software quality assurance, exhibit limitations in handling intricate business logic and extensive codebases. To address these challenges, we introduce the Intelligent Code Analysis Agent (ICAA), a novel concept combining AI models, engineering process designs, and traditional non-AI components. The ICAA employs the capabilities of large language models (LLMs) such as GPT-3 or GPT-4 to automatically detect and diagnose code errors and business logic inconsistencies. In our exploration of this concept, we observed a substantial improvement in bug detection accuracy, reducing the false-positive rate to 66\% from the baseline's 85\%, and a promising recall rate of 60.8\%. However, the token consumption cost associated with LLMs, particularly the average cost for analyzing each line of code, remains a significant consideration for widespread adoption. Despite this challenge, our findings suggest that the ICAA holds considerable potential to revolutionize software quality assurance, significantly enhancing the efficiency and accuracy of bug detection in the software development process. We hope this pioneering work will inspire further research and innovation in this field, focusing on refining the ICAA concept and exploring ways to mitigate the associated costs.

Motivation & Objective

• Address the growing challenge of detecting complex code errors and business logic inconsistencies in large, rapidly evolving software systems.
• Overcome limitations of traditional static analysis, which rely heavily on manual effort and are often inadequate for intricate logic paths.
• Propose and evaluate a novel framework—ICAA—that integrates LLMs with structured engineering processes to automate and enhance code quality assurance.
• Demonstrate the feasibility and performance potential of AI-driven agents in real-world software error detection, particularly in handling incomplete or complex codebases.
• Identify and analyze key challenges, especially high token consumption, to guide future optimization and practical deployment of such systems.

Proposed method

• Design the ICAA as a hybrid system integrating large language models (e.g., GPT-3.5-turbo), traditional static analysis components, and engineered workflows for error detection.
• Leverage the contextual reasoning and natural language understanding of LLMs to analyze code structure, detect semantic bugs, and verify business logic consistency.
• Implement a multi-step analysis pipeline: code parsing, context-aware LLM inference, and result aggregation to reduce false positives.
• Use iterative evaluation with multiple runs per codebase to ensure robustness and mitigate the non-deterministic behavior of LLMs.
• Integrate non-AI components for syntactic validation and performance optimization, balancing AI capabilities with deterministic checks.
• Apply a curated benchmark of real-world codebases to evaluate performance across diverse software contexts and complexity levels.
