AI Agent SystemsDifferent systems.
One foundation.

AI agent systems can take single-agent, multi-agent or hybrid forms while
applying the same responsibility model.

SHARED STRUCTURAL FOUNDATION

one base / multiple configurations

02

FROM ARCHITECTURE TO CONCRETE SYSTEMS

ARCHITECTURE ASKS

Which structural and execution-oriented concerns matter?

SYSTEMS ASKS

How can those concerns appear inside a concrete implementation?

QUICK ANSWER

An AI agent system connects one or more agents with tools, workflows, state and control boundaries. Start with one agent when it can complete the task reliably; add specialist agents or human steps when responsibility, parallel work or review requirements justify the coordination cost.

ONE FRAMEWORK, DIFFERENT EXPRESSIONS

These eight dimensions help describe possible systems; they are not a required configuration or a fixed ZeroField system type.

SELECTED SYSTEM EXPRESSIONS

Three illustrative expressions emerge from one shared foundation. The composition differentiates gradually rather than presenting three equivalent choices.

SHARED FOUNDATION

01  ROLE-AWARE OPERATIONAL SYSTEM

Different roles occupy different responsibility and interaction positions inside a shared context.

02  MULTI-PARTY COORDINATION SYSTEM

Participants coordinate through distributed relationships, handoffs and commitments.

03  CONTROLLED DECISION-SUPPORT SYSTEM

Supporting context reaches an explicit human authority boundary and responsibility point.

05

HOW A CONCRETE SYSTEM TAKES SHAPE

These concerns become visible inside concrete systems in different ways. Their arrangement here is editorial, not architectural.

PARTICIPANTS / ROLES

Different responsibilities, interaction positions and operational views.

AUTHORITY

Decision rights, approvals, escalation and responsibility boundaries.

COORDINATION

Actions, events, handoffs, decisions and commitments.

CONTINUITY

Current state, history, decisions, commitments, memory, knowledge and traceability.

EXTERNAL ENVIRONMENT

Organizational data, identity environments, external systems and interfaces.

INTERACTION SURFACE

How authorized participants encounter and operate the system.

editorial explanation + micro operational cues — not a canonical internal model

06

SHARED FOUNDATION, DIFFERENT EMPHASIS

The Framework is shared.
The system expression is not fixed.

Different systems can make different concerns more visually and operationally prominent—without scores, percentages, matrices or required coverage.

08

SINGLE-AGENT, MULTI-AGENT & HYBRID SYSTEMS

More agents are not automatically a better system.

Choose the simplest system that meets the task's constraints. One agent with bounded tools may be sufficient; multiple agents can help when specialized work, independent review or parallel tasks outweigh handoff, latency and state-management costs.

SINGLE-AGENT

One operational center.

One agent or role reasons across the task and invokes tools within a defined authority boundary. This keeps coordination and state simpler when specialization is limited.

MULTI-AGENT

Specialized roles collaborate.

Distinct agents can own different capabilities, contexts or responsibilities and coordinate through explicit handoffs, messages or shared workflow state.

HYBRID

Autonomy where it adds value.

A system can combine deterministic workflow steps, one or more agents and human decision points instead of making every stage agent-driven.

09

TOOLS, WORKFLOWS & HANDOFFS

Reasoning becomes operational through controlled capabilities.

AI agent systems act through tools, APIs, workflows and handoffs. The system should make it clear what capabilities exist, which role may invoke them, what context moves with the work and where an external effect requires stronger authorization or review.

TOOLS

Bounded capabilities

Retrieval, calculation, data access and external actions expose capabilities without automatically granting every agent permission to use them.

WORKFLOWS

Structured progression

Deterministic stages can surround agentic reasoning where order, validation or repeatability matters more than open-ended autonomy.

HANDOFFS

Responsibility moves explicitly

A handoff identifies the next owner, task scope, relevant state, permitted actions and unresolved decisions before work continues.

EXTERNAL EFFECTS

Actions cross boundaries

Calls into business systems, data stores, APIs or physical processes connect reasoning to consequences and may require approval or stronger controls.

COMMON COORDINATION PATTERNS

These are coordination options, not required ZeroField system types. Choose by task dependencies, parallelism, ownership and the cost of reconciling results.

01

Sequential

Work passes through a defined sequence of agents or stages when each step depends on the output or decision of the previous one.

02

Concurrent

Independent tasks can run in parallel when the latency benefit justifies coordination; results still need reconciliation before dependent actions proceed.

03

Handoff

One agent transfers responsibility to another when the task crosses a capability, authority or context boundary.

04

Manager / Orchestrator

A coordinating role decomposes work, delegates to specialists and reconciles results while remaining accountable for system-level progression.

11

STATE, MEMORY & CONTINUITY

Coordination needs a trustworthy account of what has happened.

Conversation history alone cannot establish what actually completed. Durable state records progress and commitments; recovery checks external effects before retrying uncertain work, while memory remains supporting context rather than authority.

01

Working Context

Immediate inputs and task context used during current reasoning.

02

Durable State

Progress, decisions, commitments and current system condition.

03

Memory

Historical context that can inform later behavior without becoming uncontrolled authority.

04

Checkpoints

Known states from which workflows can resume, reconcile or safely stop.

05

Recovery Context

Evidence of completed, failed and externally changed work before execution continues.

12

HUMAN OVERSIGHT, PERMISSIONS & GUARDRAILS

Operational autonomy still needs explicit control points.

System-level controls determine which agent or role may access a capability, when an action needs approval and how execution can be paused or escalated. Guardrails can constrain unsafe or out-of-scope behavior, but they do not replace clear authority and accountability.

PERMISSIONS

Who may access what?

Tool, data and system access should reflect the authority actually required for the current role and task.

APPROVAL

Which actions need a person?

Higher-risk, ambiguous or irreversible actions can require human approval before an external effect occurs.

GUARDRAILS

What must be blocked?

Deterministic checks can constrain prohibited actions, excessive loops, invalid inputs or execution outside known operating limits.

INTERRUPTION

How can autonomy stop?

Pause, cancel, override and escalation paths provide explicit intervention when continued execution is no longer justified.

13

OBSERVABILITY, EVALUATION & RECOVERY

A system should leave enough evidence to explain its behavior.

Useful observability follows more than model output. Tool calls, handoffs, approvals, state transitions, failures and recovery attempts create traces that support debugging, evaluation and later assurance.

TRACE

Execution path

Which roles acted, which tools were called and how responsibility moved.

EVALUATE

System behavior

Whether the system completed the task, respected boundaries and produced acceptable outcomes.

RECOVER

Failure handling

Separate completed, failed and unknown effects; reconcile external state before retry or resume.

WHEN MULTI-AGENT COMPLEXITY IS WORTH IT

Use more coordination only when the work needs it.

Multi-agent designs may help when specialist work, independent review or parallel execution provide a measurable benefit. Compare that benefit with handoff errors, latency, cost, state reconciliation and evaluation burden. Prefer one bounded agent when extra roles do not justify the overhead.

STRONGER FIT FOR MULTI-AGENT
  • Distinct specialist capabilities or knowledge domains
  • Independent responsibilities or authority boundaries
  • Parallel work that meaningfully reduces latency
  • Explicit review, critique or separation-of-duty roles
KEEP THE SYSTEM SIMPLER WHEN
  • One agent can use the required tools safely
  • Handoffs would mostly duplicate context
  • Extra coordination adds more failure modes than value
  • Latency, cost or debugging complexity dominates the benefit

REFERENCE CONTEXT

ZeroField’s system expressions are its own. These references provide current industry context for agents, workflows, orchestration and observability.
