AI coding agents perform better with interface skeletons than full dependency files

A new benchmark study reveals that providing AI coding agents with full dependency files, rather than just interface skeletons, can significantly reduce accuracy. The experiment, conducted within isolated Proxmox VMs, showed that a model using only function signatures and docstrings achieved a perfect score in one turn, while the model receiving full dependency code struggled and achieved a lower score over multiple turns. This approach not only improved accuracy but also drastically cut down on token usage, API costs, and execution time. AI
