Exploration Structure in LLM Agents for Multi-File Change Localization

arXiv:2606.11976v1 Announce Type: cross Abstract: Software engineering tools increasingly rely on LLM based agents to localize files to change to resolve a software issue. Most AI agents explore repositories linearly, that is, visiting one directory or file per step. We postulate that this is a structural mismatch for changes that span several subsystems. We compare linear sequential exploration against non-linear, domain-scoped parallel agentic exploration. Using SWE Bench Pro as initial benchmark, we focus on ansible as an exemplar. We construct an approach for persistent-session evaluation

Why this matters
Why now

The rapid advancement and adoption of LLMs in software engineering necessitates optimizing their operational efficiency for complex tasks like multi-file changes.

Why it’s important

Improving how LLM agents explore and interact with large codebases will significantly enhance their utility and accelerate software development, impacting productivity across industries.

What changes

This research suggests a shift from linear to non-linear, domain-scoped exploration for LLM agents, potentially making them more effective in resolving intricate software issues.
