Introduction

Generative AI is evolving from systems that simply answer questions into AI agents that assess situations, use tools, and carry out business operations.

An AI agent can:

• Search for information
• Draft emails
• Respond to customers
• Review contracts
• Operate systems

Multiple AI agents can also divide responsibilities and work together toward a shared objective.

As this kind of AI coordination advances, one question becomes increasingly important: how much autonomy should AI agents be given?

If autonomy is set too low, an AI agent becomes little more than an inconvenient system that must wait for human approval at every step.

If autonomy is set too high, flawed judgments can be executed directly, potentially causing serious harm to an organization or its customers.

AI agent autonomy therefore involves a fundamental trade-off:

Autonomy	Benefits	Costs
Low autonomy	Safer	Slower and more burdensome for humans
High autonomy	Faster	Riskier, with mistakes more likely to propagate

What we need is not a binary choice between allowing and prohibiting autonomy.

We need a mechanism that dynamically adjusts autonomy according to the situation, risk, trust, authority, and potential scope of impact.

This article compares the main approaches to controlling AI agent autonomy and proposes an integrated control model suited to the age of AI coordination.

What Is AI Agent Autonomy?

AI agent autonomy describes the extent to which an AI can make decisions and take action without waiting for human instructions or approval.

Autonomy, however, cannot be represented adequately by a single number. At a minimum, it should be broken down into the following dimensions.

Goal Autonomy

The extent to which an AI can define or modify its own goals.

Planning Autonomy

The extent to which an AI can independently develop the steps and plans required to achieve a goal.

Decision Autonomy

The extent to which an AI can choose among multiple options on its own.

Action Autonomy

The extent to which an AI can operate external systems, send messages, enter into agreements, make payments, or perform other consequential actions.

Coordination Autonomy

The extent to which an AI can delegate work to other AI agents or change their roles.

Learning Autonomy

The extent to which an AI can learn from outcomes and modify its future decision-making methods or rules.

Action autonomy and coordination autonomy require particular care. An error made by one AI agent may not remain confined to that agent.

• An incorrect instruction may be passed to another AI agent.
• Multiple agents may share the same false premise.
• A single decision may trigger a chain of downstream actions.

In an AI coordination environment, autonomy risk can spread and grow through the network. Autonomy control must therefore be designed around not only individual agents, but also the relationships among them.

Approach 1: Control Through Fixed Rules

The most basic approach is to define in advance what an AI agent may and may not do.

Examples include:

• Payment processing is prohibited.
• Transactions above ¥100,000 require human approval.
• Customer data must not be sent to external services.
• Contracts must not be approved automatically.
• Production data must not be deleted.

These rules can be implemented in programs, policies, domain-specific languages, or access-control configurations.

Pros

First, the controls are explicit. An organization can clearly specify which actions are permitted and which are prohibited.

Second, fixed rules are easy to audit. The system can record which rule caused an action to be permitted or denied.

Third, they are effective at preventing critical risks. Fixed rules are well suited to defining inviolable boundaries such as “Do not send customer information outside the organization” or “Do not delete production data.”

Cons

It is difficult to encode every real-world situation in advance. As exceptions accumulate, rules become complex and may begin to conflict with one another.

Fixed rules also do not adapt automatically when circumstances change.

They are effective at controlling what must never be done, but less suited to deciding flexibly how much autonomy should be granted in a particular situation.

Approach 2: Control Through Permissions and Sandboxing

The second approach limits the data, tools, APIs, and execution environments an AI agent can access.

For example, a sales-support agent might be allowed to read customer information but denied permission to modify contracts or process payments.

Sales Agent Capability	Permission
Customer information	Read
Proposals	Create
Contract changes	Denied
Payments	Denied

The agent’s execution environment can also be sandboxed so that its effects cannot extend beyond an approved scope.

Pros

Even if an AI makes a poor decision, the potential damage can be contained.

Separating permissions by role supports the principle of least privilege. In multi-agent environments, it also clarifies the role and responsibility of each agent.

Cons

Having permission to perform an action does not mean that the action is correct.

A sales agent may be authorized to send email and still send an inaccurate or inappropriate message.

Permission management also becomes more complex as controls become more granular. When one agent delegates work to another, the system must additionally govern permission inheritance and redelegation.

Approach 3: Human-in-the-Loop Approval

The third approach requires human approval before important decisions or actions are carried out.

Examples of actions that might be placed behind a human gate include:

• Signing a contract
• Making a payment above a specified amount
• Changing a production environment
• Sending a high-impact response to a customer
• Providing personal information to an external party
• Operating safety-critical equipment

The AI gathers information, performs analysis, and prepares options, but leaves the final execution decision to a human.

Pros

Human-in-the-loop approval preserves human responsibility for consequential decisions.

Even if the AI’s judgment is incomplete, a human can review the situation and stop the action. This approach is especially valuable in fields where accountability matters, including law, medicine, finance, and safety management.

Cons

If humans must approve every decision, much of the value of automation is lost.

An excessive volume of approval requests can also lead to approval fatigue, in which people approve requests mechanically without reviewing them carefully.

During emergencies or outside business hours, waiting for a human response may itself create operational risk.

Human-in-the-loop controls are important, but simply returning every decision to a person is not a complete model for controlling autonomy.

Approach 4: Risk-Based, Graduated Autonomy

The fourth approach adjusts autonomy according to the risk of the proposed action.

For example, agent actions can be classified as follows:

Risk	Autonomy	Control
Low	High	Execute automatically
Medium	Conditional	Post-execution review or limited execution
High	Low	Require prior human approval
Critical	None	Prohibit execution

Low-risk tasks such as information retrieval and internal document summarization can be executed automatically. Contract signing and money transfers, by contrast, require human approval.

Pros

This approach makes it easier to balance safety and operational efficiency.

Not every action has to be treated according to the same standard, allowing people to focus on the decisions that matter most. Autonomy levels can also be adjusted by business function or department.

Cons

Risk assessment is itself difficult.

The risk of the same action can change depending on the amount involved, the customer, time, location, and purpose. Simple risk categories may fail to capture this contextual complexity.

The AI performing the risk assessment may also be wrong. The system therefore needs a way to trace the basis of its evaluation.

Approach 5: Dynamic Autonomy Based on Trust

The fifth approach evaluates trust based on an AI agent’s past performance and current circumstances, then adjusts autonomy dynamically.

Here, trust is not a permanent score assigned to an AI. It is the likelihood that the AI can produce the expected outcome for a specific purpose, role, and situation.

For example, an agent that has consistently classified invoices accurately may be allowed to process routine invoices automatically.

If a transaction involves a new supplier, an unusual amount, or unfamiliar contract terms, however, trust should decrease and the process should be routed to a human reviewer.

Past Performance + Current Context + Task Risk + Knowledge Quality + Policy Compliance → Trust Evaluation → Autonomy Level

Pros

Controls can adapt as the AI’s capabilities and circumstances change.

An agent with a strong track record can be granted greater autonomy. Conversely, if failures or anomalies increase, the system can automatically reduce its autonomy.

Cons

If trust calculations are opaque, the organization cannot explain why autonomy was granted.

Overweighting past success can also create overconfidence in situations the agent has never encountered.

Reducing trust to a single number removes important differences among purposes and contexts. Trust must therefore be designed as a task- and context-dependent assessment, not as a general rating of the AI itself.

Approach 6: Mutual Oversight and Consensus Among Multiple AI Agents

In an AI coordination environment, one agent can be used to verify the judgment of another.

Separate agents can review the proposed action for risk, policy compliance, and factual accuracy:

Planner Agent → Policy Agent → Risk Agent → Execution Agent

• The Planner Agent creates the plan.
• The Policy Agent checks it against applicable rules.
• The Risk Agent assesses potential impact and risk.
• The Execution Agent carries out only authorized actions.

For important decisions, the system may also require agreement among multiple agents.

Pros

This reduces dependence on a single AI agent.

Separating planning, execution, and auditing helps prevent conflicts of responsibility. Combining models with different capabilities or knowledge may also allow one agent to identify issues another overlooked.

Cons

If multiple agents rely on the same incorrect information, they may all make the same mistake.

Adding more AI agents does not automatically improve the correctness of a decision.

When agents disagree, a new problem emerges: who makes the final decision? Consensus also adds time and cost, and may make accountability less clear.

Approach 7: Post-Execution Monitoring and Rollback

Not every risk can be predicted in advance. AI actions must therefore be monitored continuously, with mechanisms to stop or reverse them when anomalies are detected.

For example, data created by an AI can remain in a provisional state for a defined period instead of being committed immediately. If the system detects an anomaly, it can cancel the operation and restore a safe state.

Pros

This approach can address problems that were not anticipated beforehand.

For low-risk, reversible operations, it can reduce the need for prior human approval. Actual outcomes can also be used to improve policies and trust assessments.

Cons

Some actions cannot be reversed, including sent emails, published information, and physical equipment operations.

The effects of a problem may also spread before it is detected.

Rollback should therefore complement preventive controls, not replace them.

No Single Approach Is Sufficient

Each of these approaches has its own strengths and limitations.

Approach	Main Strength	Main Weakness
Fixed rules	Explicit and easy to audit	Poor at handling exceptions and change
Permissions and sandboxing	Limits the scope of impact	Does not guarantee sound judgment
Human gate	Gives humans oversight of critical decisions	Creates delays and approval fatigue
Risk-based control	Balances efficiency and safety	Risk is difficult to assess
Trust-based control	Adapts to circumstances	Can become opaque
AI mutual oversight	Reduces dependence on a single agent	Shared errors and disagreement remain possible
Monitoring and rollback	Addresses unexpected problems	Weak for irreversible actions

The goal is not to select one approach. It is to combine them in layers.

Proposal: Integrated Control Through an Autonomy Control Plane

The age of AI coordination requires more than assigning a fixed level of autonomy to each AI agent.

It requires an Autonomy Control Plane that governs the runtime autonomy of multiple agents in an integrated way.

The Autonomy Control Plane sits between AI agents and the external environment. It evaluates the following elements:

Goal

What is the agent trying to achieve?

Role

On whose behalf, and in what capacity, is it acting?

Permission

What is it authorized to do?

Context

What are the current circumstances?

Knowledge

Is the basis for the decision sufficient and up to date?

Risk

What would be the impact of failure?

Trust

How reliable is the agent in this particular situation?

Boundary

What limits must never be crossed?

The system uses these assessments to determine the appropriate level of autonomy at runtime:

Observe → Evaluate Context, Risk, and Trust → Decide Autonomy → Act, Ask, or Stop → Trace → Learn

Managing Autonomy Across Five Levels

An Autonomy Control Plane can manage autonomy using five levels.

Level 0: Observe Only

The AI may collect and analyze information, but it may not take action in the external environment.

Level 1: Recommend

The AI presents options or recommendations, but a human performs the action.

Level 2: Act with Approval

The AI prepares an action, which is executed only after human approval.

Level 3: Act with Monitoring

The AI executes automatically, and the outcome is reviewed by a human or a monitoring agent.

Level 4: Autonomous Action

Within an authorized scope, the AI independently makes decisions and carries them through to execution.

The important point is that an agent should not be assigned one permanent level.

The same agent should operate at different autonomy levels depending on the task and context.

A sales agent, for example, might automatically send general product information but require managerial approval before committing to a discount.

A facility-management agent might optimize operations automatically under normal conditions, but switch to human review or an emergency stop as conditions approach a safety threshold.

Knowledge Flow as the Foundation of Autonomy

Controlling autonomy depends not only on an AI’s capabilities, but also on the state of the knowledge reaching it.

• Is it relying on outdated rules?
• Is the evidence insufficient?
• Are the sources unverifiable?
• Are different departments using inconsistent definitions?

An AI cannot safely be granted a high degree of autonomy under such conditions.

The Autonomy Control Plane must therefore assess knowledge quality as well.

Source

Is the source of the information clear?

Freshness

Is the information current?

Meaning

Are terms defined consistently?

Relationship

Is the information connected to the relevant surrounding knowledge?

Trust

Is it reliable enough to serve as evidence?

Knowledge Flow is therefore more than a mechanism for improving answer quality. It is part of the foundation for deciding how much autonomy an AI can safely be given.

Decision Trace as the Foundation of Accountability

Controlling AI agent behavior requires recording not only the outcome, but also the decision process.

Observation → Context → Knowledge → Applied Policy → Risk and Trust → Autonomy Decision → Action → Outcome

A Decision Trace should capture:

• What the agent observed
• How it interpreted the situation
• What knowledge it relied on
• Which policies it applied
• How it assessed risk and trust
• Why it chose automatic execution or human approval
• What action it took
• What outcome followed

With a Decision Trace, an organization can answer questions such as:

• Why did the AI choose that action?
• Why did it not request human approval?
• What knowledge supported its decision?
• Which agent made the decision, and in what role?
• If the action failed, where should the system have intervened?

A Decision Trace is not merely an audit record. It is also training data for continuously improving AI coordination.

AI Coordination Also Requires Control Over “Relational Autonomy”

In a multi-agent environment, controlling the permissions of individual actions is not enough.

The system must also govern the relationships among agents:

• What may one agent ask another agent to do?
• Can it redelegate authority?
• Can it modify the plan?
• Can it rewrite shared knowledge?
• Can it stop another agent’s decision?

A Planner Agent, for example, might indirectly carry out a prohibited operation by asking a highly privileged Execution Agent to perform it.

Every inter-agent delegation should therefore include the following information:

Purpose

The objective of the request.

Scope

The permitted range of action.

Authority

The source from which the authority was granted.

Constraints

The conditions that must be observed.

Expiration

The period for which the authority remains valid.

Responsibility

The party accountable for the outcome.

A request between AI agents is not merely a message. It should be treated as a Delegation Contract carrying purpose, authority, constraints, and responsibility.

Final Proposal: Do Not Assign Autonomy—Generate It at Runtime

Autonomy has traditionally been treated as a fixed attribute of an AI system.

In an AI coordination environment, fixing autonomy in advance is dangerous.

Even a highly capable AI should have less autonomy in an unfamiliar situation. Conversely, an agent with limited experience may safely execute low-risk, reversible tasks automatically.

Autonomy should therefore not be configured once and left unchanged.

Autonomy is not assigned.
Autonomy is generated at runtime.

Autonomy should be generated at runtime as the outcome of evaluating purpose, role, knowledge, context, risk, trust, and boundaries.

The basic structure is as follows:

Knowledge Flow → Context Evaluation → Risk and Trust Evaluation → Boundary and Policy → Autonomy Control → Human Gate or Execution → Decision Trace → Feedback

• Knowledge Flow: Deliver the knowledge required for sound judgment.
• Context Evaluation: Understand the current situation.
• Risk and Trust Evaluation: Assess potential impact and expected reliability.
• Boundary and Policy: Confirm the limits that must not be crossed.
• Autonomy Control: Determine the appropriate autonomy level.
• Human Gate or Execution: Request approval or execute automatically.
• Decision Trace: Record the decision and action.
• Feedback: Update trust, policy, and knowledge.

With this structure, autonomy control evolves from a set of prohibitions into an ongoing process of coordination.

Conclusion

The main approaches to controlling AI agent autonomy include fixed rules, permission controls, human gates, risk assessment, trust assessment, mutual oversight among agents, and rollback.

None is sufficient on its own.

The age of AI coordination requires an Autonomy Control Plane that integrates these mechanisms and adjusts autonomy according to runtime conditions.

Its core elements are:

• Knowledge Flow: Deliver the right knowledge.
• Context: Understand the current situation.
• Risk: Assess the impact of failure.
• Trust: Evaluate the scope within which reliable performance can be expected.
• Boundary: Define the limits that must not be crossed.
• Human Gate: Return consequential decisions to people.
• Decision Trace: Make decisions and responsibility traceable.

The purpose of controlling AI agent autonomy is not to stop every AI action.

It is to let AI operate within safe boundaries and reduce its autonomy when uncertainty or risk increases.

It is also to expand autonomy gradually as evidence and trust accumulate.

Observe → Evaluate → Trust → Authorize → Act → Trace → Learn

The essence of AI coordination is not the rigid, centralized control of every AI agent.

It is the continuous adjustment of the relationships among AI, humans, knowledge, policy, and trust.

What the next generation of AI governance needs is not Control AI, but Coordinate Autonomy.

The goal is not to stop AI autonomy, but to cultivate and calibrate it in a trustworthy way—and connect it to the purposes of organizations and society.
