Goal-Driven Web Interaction: A Contract-Grounded Model for LLM-Orchestrated Interfaces

Large Language Models (LLMs) are reshaping interaction on the Web, enabling users to express goals in natural language rather than navigating predefined application flows. However, conversational interfaces lack structure and affordances for direct manipulation. On the other hand, GUIs struggle to accommodate fluid, intention-driven interaction. This article discusses design trade-offs that can assist this Web transition toward agent-mediated, goal-driven paradigms and models, and proposes a unifying conceptual framework clarifying how agents can interpret user goals and assemble Web interfaces. This contribution outlines a shift toward goal-driven computing on the Web, with implications for design, interoperability, and agentic architectures.
