To Think or Not to Think: Evaluating LLM Reasoning and Agents in Vulnerability Detection

Large language models (LLMs) are increasingly studied for software vulnerability detection, but the benefits of recent reasoning-enabled (“thinking”) modes remain unclear. At the same time, agentic LLM designs aim to enhance analysis through structured collaboration, while practical software security workflows require...

Engineering Sustainable Agents: A Systematic Comparison of Agentic LLMs for Developer Workflows

Large language models (LLMs) are increasingly used in software engineering, including agentic systems that coordinate multiple agents, but impose higher computational and environmental costs. In this paper, we present a comprehensive empirical study of agentic LLM systems across five software engineering tasks: code ge...

We Must Have Missed This Comment: Detecting and Repairing Stale Function References in Linux Kernel Comments

ReCite, a three-stage approach to identify and repair stale references in code comments that appear to reference functions but for which no matching function can be found in the current codebase, and tracing the evolution history of each unresolved symbol through the Git history, is proposed.

"Go Home Copilot, You're Drunk": Understanding Developer Responses to Agent-Generated Code Review Comments

The first large-scale empirical study on the resolution of agent-generated code review comments is presented, revealing that the presence of an inline code suggestion is the strongest predictor of comment resolution, while lengthy and complex comments are less likely to be acted upon.
