OpenClawBench: Benchmarking Process-side Anomalies in Real-world Agent Execution Trajectories (NeurIPS 2026, Evaluations & Datasets Track)

Code: https://github.com/YangzeLiu/OpenClawBench

OpenClawBench labels process-side anomalies in LLM agent trajectories: cases where an agent commits to an action or a confident answer while the information it needs is missing, ambiguous, or contradicted, whether or not the task outcome looks correct. Trajectories were generated by six open-weight backbones running as tool-using agents on BFCL tasks. Each trajectory carries a binary anomaly label, one of five anomaly subtypes, an onset step, and cited evidence steps.

Join human_verified to trajectories on (source_model, trajectory_id).

How the labels were produced

Silver labels. An LLM judge (DeepSeek-V4-Pro) annotated every trajectory with a self-contained 5-class prompt (in the code repository). Released rows are the high-confidence subset, split 9:1 into train and test, stratified by source model.

Human labels (human_verified.jsonl). Two annotators labeled each trajectory independently, blind to each other and to the silver labels; disagreements were resolved by adjudication under written boundary-case rules (TAXONOMY.md). Labels are binary plus subtype. Two subsets:

gold300: 300 test trajectories, 50 per source model.
supp140: 140 trajectories stratified by silver subtype to cover the rare subtypes (25 silver-normal; 25 each of capability_gap_overcommitment, weak_evidence_commitment, write_under_unresolved_ambiguity; 20 each of premature_external_write, error_ignored_escalation), disjoint from gold300. Because of the stratification its anomaly rate is not representative of the corpus.

Source models

DeepSeek-R1, GLM-4.5-Air, GPT-OSS-20B, Qwen3.5-9B, Qwen3.6-27B, Qwen3.6-35B-A3B, roughly balanced across the corpus.

Intended use and limitations

Intended for training and evaluating trajectory-level anomaly detectors, subtype classification, onset localization, and studying LLM-judge reliability against human labels.

Silver labels come from a single LLM judge and contain errors; use human_verified for evaluation claims.
Only open-weight backbones on BFCL function-calling tasks, English only; behavior of proprietary agents or open-ended tasks is not covered.
Subtype boundaries (notably weak_evidence_commitment vs. capability_gap_overcommitment) are inherently fuzzy; see TAXONOMY.md.
Trajectories are model outputs on public benchmark prompts and contain no personal data. API keys and access tokens appearing in trajectory text were replaced with placeholders.
