The Devil Is in the Det[Ai]Ls: AI Agents, Ghost Students, and the Crisis of Verified Presence in an Agentic AI World

Abstract

The transition from reactive Generative Artificial Intelligence (GenAI) to agentic AI systems marks a categorical shift in digital education, moving beyond simple content generation to goal-oriented, autonomous execution. This paper explores the emergence of the ghost student: a digital surrogate created by the coupling of Large Language Models (the mind) and agentic AI browsers (the body). These entities are capable of navigating Learning Management Systems (LMS), engaging with content, and completing assessments with human-like mimicry, often rendering the actual learner's presence optional. We argue that this phenomenon creates a verification gap that traditional proctoring and detection tools are structurally unable to close. The implications of this shift are profound: the accumulation of cognitive debt through the offloading of productive struggle, the erosion of credential trust, and significant legal vulnerabilities regarding data protection frameworks. By analyzing the technical capabilities of agentic browsers alongside pedagogical theory, this paper argues that the crisis is structural. We conclude that to safeguard the integrity of higher education, institutions must move away from output-based assessments and toward designing for human presence. Such a view necessitates a radical shift toward process-oriented, dialogic, and reflective assessment models that value the human in the room over the algorithmic proxy.
