When Claude Code Reviews Its Own PR, Who Reviews Claude?

An AI code review experiment compared two tools, Claude Code and Qodo, in evaluating a pull request for a Python tool on an MCP server. Claude Code, which implemented the changes, used a filtering approach to highlight only high-confidence issues, resulting in a single identified bug, while silently suppressing others. In contrast, Qodo, an independent reviewer, provided a detailed spectrum of findings, categorized by severity and type, with actionable remediation guidance, emphasizing the significance of issues within responsibility boundaries like server entry points. This experiment underscored the importance of maintaining independent oversight in AI code reviews to ensure comprehensive risk assessment and accountability, highlighting the potential pitfalls of allowing a single AI agent to act as both developer and reviewer.
