Before Agent Tells The Lie: Has Deception Already Been Represented?

Large language model (LLM)-based agents can exhibit deceptive behavior during task execution, including hiding failures, fabricating results, or falsely signaling task completion. Existing monitoring approaches mainly detect deception after it appears in observable actions or outputs. In this paper, we investigate whet...

Code2Math: Can Your Code Agent Evolve Math Problems Through Exploration?

This work introduces a multi-agent framework designed to perform problem evolution while validating the solvability and increased difficulty of the generated problems, and provides empirical evidence that code-driven agents can serve as a viable mechanism for synthesizing high-difficulty mathematical reasoning problems...

Buried in Textual Debt: Context Pruning with Visual Evidence Preservation for MLLM Agents

Across multi-step visual tool-use benchmarks, SPARE achieves the highest average accuracy among pruning methods while removing 37.89-64.58\% of reasoning tokens, showing that reducing textual dominance restores reliance on visual evidence and mitigates over-conditioning on self-generated language.
