AI Agents Disagree on Code Review Findings
Three AI models (Claude, Codex, and Gemini) independently reviewed the codebase of a popular Python CLI tool, llm, and found some disagreements in their findings.
Why it matters
This article demonstrates the value of using multiple AI agents to review code, as it can uncover disagreements that provide deeper insights into the codebase.
Key Points
- 1The review process involved using code analysis tools to provide structural information to the AI models
- 2The AI models identified several potential issues, with some findings confirmed by all three models and others disputed by the third model
- 3The disagreements highlighted the importance of having multiple AI agents review code, as a single model's assessment may not capture the full context
Details
The article describes a process where the authors use three AI models (Claude, Codex, and Gemini) to independently review the codebase of the llm Python CLI tool. The review process involved using the authors' own code analysis tools to provide structural information about the codebase to the AI models. The models then identified several potential issues, with some findings confirmed by all three models and others disputed by the third model. The disagreements between the models highlighted the importance of having multiple AI agents review code, as a single model's assessment may not capture the full context and nuance of the codebase. The article provides examples of the types of findings the models identified, including issues related to error handling, memory usage, and concurrency, and discusses how the third model's assessment helped distinguish genuine defects from defensible design choices.
