AI Code Review Only Catches Half of Your Bugs

This article explores the limitations of AI code review, showing that structural analysis catches only about 50% of security defects, while the other half are design flaws invisible without understanding intent. The author shares a personal anecdote (a bus tracker app that showed the wrong direction) and a real bug found in Google's Gson library to illustrate the importance of requirements. The open-source Quality Playbook method is introduced, which derives requirements from code and documentation to catch hidden bugs.

Key points

  • Structural analysis (including AI code review) detects only about half of security bugs; the other half are design flaws requiring knowledge of intent.
  • The author's AI-generated bus tracker app failed because it didn't know the intended direction.
  • The Quality Playbook found a long-hidden bug in Google's Gson library by deriving requirements from code and documentation.
  • To improve AI code review, feed it your intent (requirements), not just your code.
