The Last Human-Written Paper: Agent-Native Research Artifacts

TL;DR

The paper introduces the Agent-Native Research Artifact (ARA), a structured, machine-executable research package that preserves the full research process, including failures, to improve reproducibility and AI understanding of scientific work.

Contribution

It proposes a novel protocol and ecosystem for transforming traditional papers into executable, comprehensive research artifacts that enhance reproducibility and AI comprehension.

Findings

ARA improves question-answering accuracy from 72.4% to 93.7%

ARA increases reproduction success from 57.4% to 64.4%

Preserved failure traces in ARA accelerate research progress

Abstract

Scientific publication compresses a branching, iterative research process into a linear narrative, discarding the majority of what was discovered along the way. This compilation imposes two structural costs: a Storytelling Tax, where failed experiments, rejected hypotheses, and the branching exploration process are discarded to fit a linear narrative; and an Engineering Tax, where the gap between reviewer-sufficient prose and agent-sufficient specification leaves critical implementation details unwritten. Tolerable for human readers, these costs become critical when AI agents must understand, reproduce, and extend published work. We introduce the Agent-Native Research Artifact (ARA), a protocol that replaces the narrative paper with a machine-executable research package structured around four layers: scientific logic, executable code with full specifications, an exploration graph that preserves the failures compilation discards, and evidence grounding every claim in raw outputs. Three mechanisms support the ecosystem: a Live Research Manager that captures decisions and dead ends during ordinary development; an ARA Compiler that translates legacy PDFs and repos into ARAs; and an ARA-native review system that automates objective checks so human reviewers can focus on significance, novelty, and taste. On PaperBench and RE-Bench, ARA raises question-answering accuracy from 72.4% to 93.7% and reproduction success from 57.4% to 64.4%. On RE-Bench's five open-ended extension tasks, preserved failure traces in ARA accelerate progress, but can also constrain a capable agent from stepping outside the prior-run box depending on the agent's capabilities.
