Agent4cs: A Multi-agent System for Code Summarization in Large Hierarchical Codebases
Summary
Agent4cs is a multi-agent framework designed to summarize large, hierarchical codebases, addressing challenges posed by obfuscated structures and incomplete documentation. Unlike existing solutions that treat code as flat text or rely on single language models, Agent4cs employs a bottom-up approach. It integrates a summarization agent for robust summaries, a keyword-extraction agent to identify critical information from subfolders, and a quality-assurance agent for iterative refinement. Evaluated on 7 frontier models, Agent4cs demonstrated an average 8% improvement in semantic consistency across all folder levels and achieved up to 38% gains in normalized keyword coverage rate compared to two structured prompting baselines.
Key takeaway
For Machine Learning Engineers working on code understanding tools, consider multi-agent architectures. Agent4cs demonstrates significant improvements in semantic consistency and keyword coverage for large, hierarchical codebases. You should explore integrating specialized agents for tasks like summarization, keyword extraction, and quality assurance to enhance the robustness and completeness of your code analysis systems.
Key insights
Agent4cs uses a multi-agent system to summarize large, hierarchical codebases more effectively than single-model approaches.
