SciTrace: Trajectory-Aware Safety Reasoning for Scientific Discovery Agents
TLDR
SciTrace integrates safety reasoning into every stage of scientific discovery agents, using trajectory-aware checks to prevent compositional tool-chain risks.
Reasoning
The paper presents a novel framework that addresses a critical gap in safety for LLM-based scientific agents, with strong empirical evaluation across multiple domains and models. However, the abstract lacks details on baseline comparisons and potential limitations of the approach.

Innovations
- SciTrace framework that weaves safety reasoning into every stage of the scientific agent pipeline, addressing the separation of safety layers from core reasoning.
- Safety-Intrinsic Reasoning Loop (SIR) that maintains a cumulative risk state across Thinker, Experimenter, Writer, and Reviewer stages through joint task-and-safety deliberation.
- Compositional Tool-Chain Verifier (CTV) that performs trajectory-aware safety checks before execution to catch risks from multi-step tool sequences.
Methodology
SciTrace couples SIR and CTV mechanisms. Evaluated on 240 high-risk research tasks and 120 tool-related risk tasks across six scientific domains, using four backbone models, comparing against other frameworks (baselines not specified). Metrics include tool call safety, adversarial robustness, scientific output quality, and detection of compositional tool-chain escapes.
Key Results
SciTrace achieves state-of-the-art safety, improves tool call safety and adversarial robustness while preserving scientific output quality, and detects 78.8% of compositional tool-chain escapes missed by single-step monitors.
