Common Bugs in Devin-Generated Code

Devin builds autonomously without human checkpoints on each decision. When it encounters an error, it sometimes adds a workaround rather than fixing the root cause, leading to layers of patches

Devin's autonomous nature means bugs compound. An early incorrect assumption leads to workarounds that mask the root issue. Retry logic that hides failures instead of fixing them. Dependencies that conflict because they were added at different stages without reconciliation. Implicit state that makes the system work in development but fail under different conditions

Start by running your app through its complete user flow — sign up, use every feature, try edge cases like empty inputs and invalid data. Most Devin bugs surface when you go off the happy path. Use your browser's developer tools to watch for console errors, failed network requests, and unhandled promise rejections. TypeScript's strict mode will catch many issues at compile time if it's not already enabled.

For async errors, wrap every server-side operation in try/catch blocks and return meaningful error messages. For state bugs, consider whether the state belongs in the URL, in a server component, or in client state — Devin often defaults to client state when server state would be more appropriate. For data fetching issues, implement proper loading and error states for every data-dependent component.

The best way to prevent Devin bugs from reaching production: enable TypeScript strict mode, add ESLint rules for common mistakes (no-floating-promises, exhaustive-deps), and write tests for critical user flows. Even basic smoke tests catch the majority of issues.
