AI is fantastic at reducing friction in our daily work. It can trace unfamiliar code, generate tedious boilerplate, explain an API, propose refactors, write tests, hunt through logs, and even suggest five possible causes for a bug before you're done with your coffee. Used well, it can feel like a super fast technical collaborator. But this speed creates its own trap. A plausible answer can feel finished long before it has actually been verified.
AI coding tools are remarkably good at producing answers that *look* right. The code is clean. The explanation sounds confident. The function names make sense. There may even be comments describing exactly why the solution works. And sometimes it does work. Other times, the model might invent an API method, use an outdated configuration format, misunderstand a library version, ignore an edge case, weaken a security check, or fix a symptom while leaving the real bug untouched.
The most dangerous failures aren't always the ones that immediately crash the application; those are usually easy to catch. The more dangerous failures are the ones that *appear* to work. An authentication change might allow valid users to sign in while accidentally bypassing an authorization check. A database migration might succeed against an empty development database but fail on real production data. A generated test might pass because it reproduces the same incorrect assumption as the implementation. The app starts, the tests pass, and the agent announces success. But that still doesn't mean the work is correct.
So, if an AI coding agent says a library supports something, check the documentation. If it changes authentication code, inspect the security implications. If it writes a database migration, read the SQL carefully. Run the tests, check the diff, and understand your project's dependencies. Your judgment and expertise are still indispensable.
