AI coding agents promise a 55% productivity boost, but what if they're silently introducing critical bugs into your codebase? These tools are powerful but not yet production-ready due to fundamental limitations. Their brittle context windows struggle with large codebases, often forgetting crucial dependencies, while their shallow understanding of code leads to broken refactors that require significant manual fixes. Furthermore, they lack operational awareness, proposing changes that ignore real-world constraints like database loads or security protocols, with Gartner predicting 75% of enterprise AI deployments will fail due to such blind spots. This means they are best viewed as assistants, not autonomous engineers, requiring constant human oversight. Use them for generating boilerplate or brainstorming ideas, but never for unsupervised refactoring or production deployments.
