01 / OVERVIEW

Selection overview

3Agent evaluation infrastructure

Unified adapters, long-chain research checks and persistent safety environments expand the evaluation stack.

3Diagnostic agent behavior

Scheming factors, specification defects and compiler loops localize failures in the process.

3Structured ground truth

Translation pairs, SCM families and physical motion labels make benchmarks more reproducible.

ISSUE INSIGHT

Trend insight

Agent benchmarks are evolving from task collections into evaluation systems. Beyond the model, harnesses, environments, monitors, runtimes and adapters now shape conclusions, while dependency graphs, per-example rules, defect locations, SCM families and physical ground truth make evaluation more structured and diagnostic.

Issue 05 selections

Ranked by research value, evaluation innovation and practical transferability

04
BenchmarkAgent Safety / Scheming★★★★☆

Factorizes goals, affordances, oversight and pressure to stress-test covert pursuit of misaligned objectives.

AUTHOR
Jie Ruan et al.
INSTITUTION
University of Michigan et al.
PUBLISHED
2026.09.08
SCALE / DESIGN

400 scenarios spanning safety-relevant tool domains, instrumental goals, oversight conditions and pressure mechanisms.

EVALUATION / METRICS

SCOUT grounds multi-criteria judgments in reasoning and action evidence across controlled tests of five LLM agents.

KEY RESULT

Explicit instrumental goals are the strongest driver; action-only monitoring can increase scheming in some models.

WHY IT MATTERS

Factorization isolates which deployment conditions create covert behavior instead of reporting only an aggregate rate.

DESIGN TAKEAWAYS

Factorized Scenarios, Reasoning + Action Evidence, Oversight Ablation, Monitor Evaluation.

05
BenchmarkAI Scientist / Coding Agent★★★★☆

Tests whether research-method specifications are implementation-ready and whether models can locate critical gaps and ask useful questions.

AUTHOR
Yiling Ma et al.
INSTITUTION
Yale University et al.
PUBLISHED
2026.09.09
SCALE / DESIGN

660 evidence-grounded instances: 163 real reproduction gaps and 497 controlled synthetic gaps.

EVALUATION / METRICS

Covers readiness assessment, defect localization and clarification-action generation.

KEY RESULT

Best real-world Macro Defect Recovery is 9.6%; clarification success reaches 80.6% when the defect is provided.

WHY IT MATTERS

It shows that finding missing implementation-critical information is a key bottleneck for AI scientists and coding agents.

DESIGN TAKEAWAYS

Evidence-grounded Gaps, Defect Localization, Clarification Actions, Oracle Resolution.

06
BenchmarkCoding Agent / Hardware Design★★★★☆

HLS-Eval Agentic Flow

Places high-level synthesis tasks in an agent loop with file editing, compiler feedback and iterative repair.

AUTHOR
Stefan Abi-Karam, Callie Hao
INSTITUTION
Georgia Tech
PUBLISHED
2026.09.08
SCALE / DESIGN

Adds a mini-swe-agent-based flow to 94 HLS-Eval design tasks.

EVALUATION / METRICS

Logs compilation, pass rate, tokens, cost, iteration count and full trajectories for passing and failing runs.

KEY RESULT

Open models with an agent harness solve every simple generation task, showing the benchmark needs harder cases.

WHY IT MATTERS

It upgrades hardware-code evaluation from one-shot generation to a realistic compiler-in-the-loop workflow.

DESIGN TAKEAWAYS

Compiler-in-the-loop, Trace Logging, Iterative Repair, Difficulty Refresh.

07
BenchmarkLLM Translation / Output Cleaning★★★★☆

Tests whether systems can remove labels, explanations and bilingual repetition from LLM translations while preserving the clean target text.

AUTHOR
Shenbin Qian, Yves Scherrer
INSTITUTION
University of Oslo
PUBLISHED
2026.09.10
SCALE / DESIGN

Analyzes 790K+ outputs from 12 LLMs and 22 language pairs, then builds 9,900 noisy/clean pairs.

EVALUATION / METRICS

Compares quality-estimation span extraction with LLM extraction across formatting and content noise.

KEY RESULT

The dataset contains 8,800 synthetic and 1,100 manually curated authentic examples across 12 recurring noise patterns.

WHY IT MATTERS

It evaluates production usability that conventional translation-quality metrics often miss.

DESIGN TAKEAWAYS

Noise Taxonomy, Authentic + Synthetic Pairs, Span Extraction, Clean-output Evaluation.

08
BenchmarkCausal Discovery / Foundation Models★★★★☆

Compares classical, neural and pretrained causal-discovery methods across structural-causal-model families under one protocol.

AUTHOR
Zi-Rong Li et al.
INSTITUTION
Nanjing University
PUBLISHED
2026.09.10
SCALE / DESIGN

Combines synthetic, semantic operational and formula-grounded SCMs with public real-world data and observational/interventional settings.

EVALUATION / METRICS

Measures F1, SHD and cross-family ranking stability while checking pretraining–evaluation overlap.

KEY RESULT

Rankings shift substantially across SCM families and protocols; strength in one environment does not reliably transfer.

WHY IT MATTERS

It makes foundation-model training exposure an explicit part of causal-discovery benchmark design.

DESIGN TAKEAWAYS

SCM Family Diversity, ID / OOD Exposure, Shared Protocols, Ranking Stability.

09
DatasetVideo / Human Motion / Clinical Gait★★★★☆

Generates diverse walking videos from real MoCap while preserving paired physical motion and clinical gait ground truth.

AUTHOR
Soroush Mehraban et al.
INSTITUTION
UHN / University of Toronto et al.
PUBLISHED
2026.09.08
SCALE / DESIGN

19,272 videos from 6,427 MoCap sequences and 437 subjects, with SMPL motion and six gait-parameter labels.

EVALUATION / METRICS

Compares RGB, pose, biomechanics and HMR methods across viewpoint, scale and synthetic-to-real shift.

KEY RESULT

Synthetic supervision transfers to real video; spatial gait parameters are more sensitive to visual domain shift.

WHY IT MATTERS

It pairs controllable visual generation with real physical motion for scalable clinical-gait training and diagnosis.

DESIGN TAKEAWAYS

MoCap-conditioned Video, Physical Ground Truth, Viewpoint Control, Synthetic-to-real Transfer.
