OpenSpec addresses the unpredictability of AI coding assistants by introducing a lightweight, spec-driven layer. It ensures humans and AI align on requirements before code is written, fostering predictable and organized development. The framework promotes an iterative workflow, allowing flexible updates to artifacts and managing each feature change within its own structured folder. It integrates seamlessly with numerous AI tools through intuitive slash commands, making it a versatile solution for enhancing AI-assisted development across various project scales.
