Benchmarking LLM Agents on Real-World Biological Database Curation for Data-Driven Scientific Discovery

High-quality biological databases are the bedrock of data-driven scientific discovery. However, the construction of these resources remains a labor-intensive bottleneck, particularly for emerging research frontiers where structured data is non-existent. While LLM-based agents have catalyzed progress in downstream scientific modeling, their potential to automate the critical upstream challenge of database curation remains largely untapped. To bridge this gap, we introduce BioDataLab, a rigorous benchmark comprising 100 tasks meticulously derived from 57 high-impact database publications. BioDataLab evaluates the capability of autonomous agents to transform raw, heterogeneous biological resources into structured, analysis-ready databases. Unlike static evaluations, BioDataLab provides a fully interactive environment encompassing data retrieval, extraction, annotation, and integration, featuring process-oriented curation targets and contamination-control checks. We benchmark 11 state-of-the-art LLMs (including Gemini-3.0, GPT-5.2, and Claude-4.5) under different agent frameworks, revealing a substantial capability gap: the top-performing model achieves only a 40% success rate. Further error analysis identifies significant bottlenecks in multi-step tool orchestration and adherence to complex biological data formats. These findings underscore that while LLMs are proficient in downstream reasoning, autonomous upstream curation remains a formidable frontier. All data and codes are available at GitHub.

Safety Does Not Compose: Non-Decaying Loop State for Autonomous LLM Agents

Large language model agents are increasingly deployed as autonomous loops. Starting from one human goal, such a system repeatedly discovers work, plans, executes tool calls, verifies outcomes and persists state across many unattended iterations. The agent safeguards in wide use, however, are defined over a single trajectory, and their safety state is re-initialized when the next trajectory begins. We show that this is a failure of composition rather than an implementation detail. Our central result is a separation: against an attack whose evidence is fragmented across several iterations, every trajectory-scoped monitor has a true-positive rate equal to its false-positive rate, however expressive it is, because the evidence it would need never appears in the window it sees, whereas a monitor retaining cross-iteration state separates the two perfectly. We further show that the obvious repair of carrying a geometrically decaying risk score is insufficient, because the cooling-off period a patient adversary must wait is a constant that does not grow with the horizon $N$. We then present LoopHarness, which restores a persistent, non-decaying safety state at the loop level. Under mediated commits and an arbiter detection floor $\delta_M$, it bounds the expected number of unauthorized irreversible actions by $B+m-1+m/\delta_M$, a constant in $N$, of which the $B+m-1$ term is decided by a model-free rule and therefore survives a fully colluding verifier. We give a complete evaluation protocol on native Agent-SafetyBench tasks with paired clean and attacked episodes, an outer-state attack suite whose decisive evidence exists only across iterations, per-module ablations, and an adaptive white-box red team.
