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...

SWE-Duel: Towards a Self-Scaling Arena for Coding Agents

Static coding benchmarks are fixed at release. Over time their tasks leak into training data, and stronger agents eventually saturate them. We argue that a benchmark should instead aim to be self-scaling: its tasks and oracles are created at evaluation time, so no content exists in advance to leak, and its difficulty i...

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...

VulContextBench: A Benchmark for Security Context Retrieval in Coding Agents

Vulnerability-detection benchmarks score the verdict an agent reaches, not the evidence it gathered. A model that recalls a CVE from pretraining therefore scores the same as one that traced the data flow. We study a task where this difference matters, deciding whether a commit introduces a vulnerability. Instead of sco...

AgentChaos: Chaos Engineering for Agent Systems via Programmatic Fault Injection

Evaluations across agent systems, benchmarks, and backbone LLMs under 65 fault configurations show that all systems degrade under fault injection, suggesting that robustness depends on system implementation rather than model capability.

Graph Is the Verifier: Agentic Reinforcement Learning for Interprocedural Vulnerability Detection

VulAgentRL is proposed, an agentic RL framework for interprocedural vulnerability detection built on a Code Property Graph (CPG), which outperforms state-of-the-art baselines, including frontier models, on the strict pair-wise-correct metric while issuing fewer tool calls, and its advantage persists on an out-of-distri...

CoSA: Context-Aware Severity Assessment via Context Analysis with Large Language Models

Experiments on real-world vulnerabilities show that CoSA consistently outperforms function-level and pure-LLM baselines, suggesting that explicit, metric-oriented repository context retrieval is crucial for practical and reliable automated severity assessment.

Anomaly Management in Unmanned Aerial Vehicles: A Systematic Literature Review

This survey presents a comprehensive review of research studies closely related to UAV anomalies published between 2015 and 2025, covering 111 papers from academic and industrial sources, and introduces a unified five-pillar taxonomy that organizes existing work across the full anomaly management lifecycle.
