Code Review is a Conversation: Toward Conversational AI Review Assistants
Summary
This vision paper advocates for a paradigm shift in AI-based code review, moving from current "one-shot commenting" tools to "conversational AI review assistants." Existing approaches, often relying on Large Language Models (LLMs), primarily generate warnings or suggestions, overlooking the collaborative, conversational nature of human code review, which involves asking questions, negotiating trade-offs, and documenting rationale. The authors argue this limited framing can lead to tools misaligned with developer workflows, potentially reducing review quality and increasing cost [18]. The proposed conversational assistants would identify when discussion is needed, ask grounded questions, respond to developer explanations, summarize issues, capture rationale, and know when to abstain or escalate. This shift necessitates novel evaluation methodologies assessing conversational value and impact on software evolution, rather than just comment resemblance or defect detection. A research agenda is outlined for modeling review conversations, designing effective AI interventions, evaluating human-AI interactions, and integrating these assistants into real development workflows.
Key takeaway
For AI Engineers designing code review tools, you should shift your focus from generating isolated comments to enabling multi-turn conversations. Your systems must be capable of asking clarifying questions, responding to developer input, and documenting rationale, rather than merely flagging issues. This approach will lead to more effective human-AI collaboration, improving overall code quality and knowledge transfer during the review process. Consider evaluating your tools based on their impact on review outcomes and decision-making, not just comment accuracy.
Key insights
Code review is a conversation, not a one-shot commenting task, requiring AI assistants to be interactive partners.
Principles
- Review value extends beyond the final patch to knowledge production.
- AI review tools should prioritize conversational actions over comment generation.
- Abstention and escalation are necessary AI review capabilities.
Method
The paper proposes a five-stage loop for conversational AI review: observe current state, estimate intervention benefit, select action (e.g., ask question, request evidence), update state, and close rationale near integration.
In practice
- Design AI to ask clarification questions, not just suggest changes.
- Evaluate AI by its effect on review outcomes, not comment similarity.
- Model review threads, including replies and revisions, not just isolated comments.
