The Agentic Shift: A Structural Redesign of Human–Machine Experience

The emergence of agentic AI systems—software capable of interpreting intent, planning actions, and executing outcomes without step-by-step instruction—creates a structural break in user experience and organizational governance. This paper introduces the Supervisory Coherence Model (SCM), a framework linking autonomy anxiety, the undo contract, negotiated interaction grammar, interruption budgeting, and episodic interface architecture as a causal system governing human–agent collaboration. Drawing on supervisory control, calibrated trust, situational awareness, and sociotechnical systems research, the paper proposes design primitives—reversibility, provenance, progressive disclosure, risk-tiered approvals, and escalation routing—that maintain supervision under autonomy. It further argues that agentic systems redistribute decision authority within organizations, creating governance and accountability gaps that require explicit institutional design.
