Imagine this. With AI influencing perception and action of millions of people.
How did we get here?
From Instrument to Actor
Software is shifting from instrument to actor, from tool to agency. We are moving from command to intent-based interactions. And this changes everything.
What Is Agency
Agency is the structured capacity of a system to perceive, interpret, decide, remember, and act with consequential effect across time and systems.
Shaped by Agency
As software shapes our collective imaginary, agents shape our imaginary and actions. We need new methods to understand how these systems participate in human life.
Lost in Alignment
The spectrum of autonomy vs oversight. Where does alignment live?
Human–Agent Systems Design
Agency is the Material
The structured capacity to perceive, interpret, decide, remember, and act.
Relationship is the Form
Who sets intent, what is inferred, when action is taken, how interruption works.
Environment is the Context
Workflows, teams, organisations, policies, norms, legitimacy, governance.
The Irreducible Core
The irreducible object of this discipline is the human–agent relationship across time, space, and environments.

It is about how humans live with systems that act on their behalf.
Technically grounded. Experientially governed.

The HAX Designer
The HAX designer is an architect of human–agent relations. Beyond styling interfaces - designing the conditions under which agentic systems operate.

Building Systems of Agents
The New Organisation
Organisations are becoming mixed environments of humans and agents. Each human manages shadow agents and teams of sub-agents acting on their behalf.
Orchestration Patterns
Multi-Agent Systems: combining groups of humans and agents. Agency is now a property of the network.
Agent Communication
LLM / Prompting
Human-to-Agent communication via natural language.
A2A
Agent-to-Agent structured communication.
MCP
Model Context Protocol - reverse delegation.

HAX must make agency governable.
Ashby's Law of Requisite Variety: a control system must generate at least as much variety as the system it regulates.
Designing for Superintelligence
Millions of data points processed every second - funnelled to the human mind. Ecological interface design meets the generative frontier.

Glossary
Thank You
A well-designed agentic system does not merely work.
It makes machine agency intelligible, steerable, and legitimate
in human life.
HAX IS THE DESIGN OF THE HUMAN EXPERIENCE, CONTROL, AND GOVERNANCE OF AGENCY IN MIXED HUMAN–MACHINE SYSTEMS.
