[counterintuitive] AI code review and linters catch the same bugs so you only need one

Run both AI review AND traditional static analysis/linters. They catch different, largely non-overlapping bug classes. AI catches some semantic issues but misses deterministic rule violations. Linters catch rule violations but miss semantic issues. Neither catches business logic errors. All three layers are needed.

Journey Context:
There is a mistaken belief that AI code review subsumes traditional static analysis. In reality: \(1\) AI is non-deterministic—it might catch a bug in one run and miss it in the next, while linters are deterministic and catch the same issues every time. \(2\) AI misses entire categories that linters catch reliably: unused imports, cyclomatic complexity violations, deprecated API usage, style violations, missing required annotations. \(3\) AI catches things linters cannot: a variable name that does not match what the function returns, an error message that does not match the error type, a logical branch that can never be reached given the surrounding context. \(4\) Neither catches the most important class: business logic errors that require understanding intent. The correct mental model is three complementary layers: linting for syntax/style/rules, AI for some semantic issues, and humans for intent and business logic.
