Agent4cs: A Multi-agent System for Code Summarization in Large Hierarchical Codebases

arXiv:2607.01425v1 Announce Type: new Abstract: Understanding large, complex codebases, especially those with obfuscated structures and incomplete documentation, remains a significant challenge. Existing code summarization solutions often rely on a single language model or coding assistant like Claude Code, and treat source code as flat text, underutilizing the rich interdependencies and hierarchical information within a repository. To address these shortcomings, we propose Agent4cs - a multi-agent framework that summarizes large codebases in a bottom-up fashion, where a summarization agent fo

Why this matters
Why now

The increasing complexity of large codebases and the limitations of single-model AI summarization necessitate more sophisticated multi-agent approaches for code understanding.

Why it’s important

This development indicates a move towards more intelligent and autonomous AI systems capable of handling complex software engineering tasks, directly impacting productivity and development cycles.

What changes

Code summarization shifts from basic text processing to a hierarchical, multi-agent approach, enabling deeper understanding and more effective navigation of large codebases.
