How do I decide which actions an AI agent should need approval for? Require a human decision before actions that are sensitive, consequential, externally visible, broad in scope, or difficult to reverse. Let narrowly scoped, read-only work run with fewer interruptions. Then enforce those boundaries in the tools and authorization checks—not just in the agent’s instructions—and show reviewers exactly what they are being asked to approve.
How do I keep human checkpoints useful without making people approve every little thing? Match prompts to risk: gate high-impact actions, make each prompt specific enough to support a real decision, and monitor whether the rules still fit the agent’s permissions and work.

Set the boundaries before deployment
Begin with the actions the agent can take, the resources it can touch, and the consequences of getting an action wrong. An approval prompt is one control in that design; it does not make an otherwise overpowered agent safe.

Policy defines which actions need review and who is accountable. The system must then enforce that policy at the point of action. Instructions telling a model not to perform a prohibited operation are not an enforcement boundary.
#1 Best Overall
- Limit capability: Give each tool and credential only the permissions needed for its task. Microsoft’s AI agent shared responsibility model recommends that each tool or connector hold only the required permissions.
- Authorize each action: Check whether the requested operation is allowed on the specific target when it is attempted. Initial consent or broad access to a tool is not a substitute for action-level authorization.
- Deny by default: Do not expose unnecessary tools or operations. For an operation that requires approval, block execution unless a valid approval has been received.
These controls should work regardless of what the model says. In engineering terms, fail closed for gated actions: if the approval mechanism is unavailable, the action does not proceed. Where possible, prevent an ungated alternate tool or route from doing the same prohibited thing.
Choose an approval band for each action
Use the action’s impact, data sensitivity, breadth, and reversibility to set its approval level. The bands below are a practical policy model, not a universal standard or a matrix prescribed verbatim by a source.
| Band | Typical actions | Control |
|---|---|---|
| Usually autonomous | Narrow, read-only lookups or drafts that do not disclose sensitive information or create an external side effect. | Keep the accessible data and tools constrained; log activity according to organizational policy. |
| Review or confirm by context | Reversible edits to shared records, access to sensitive information, or actions whose scope exceeds what the user requested. | Require review when the affected person, data sensitivity, reach, or likely impact makes independent execution inappropriate. |
| Approval required before execution | Irreversible deletion; payments or purchases; production changes; external messages or publication; high-impact decisions about people; or broad actions with compliance implications. | Pause before execution and require an authorized person to approve. Provide a reject or stop path. |
Do not treat a particular dollar amount as an evidence-based universal cutoff. Set transaction thresholds through your organization’s risk policy, taking account of the agent, task, and environment, and revisit them when any of those change. The cited Microsoft guidance supports risk-based controls but does not prescribe a generally valid monetary limit.
Make the approval prompt a real decision
Put the checkpoint before the action—not after the agent has already sent the message, changed the record, or initiated the payment. A concise review card should let the person understand what will happen and judge whether it is appropriate.
- Action and target: State the operation and identify the recipient, record, account, system, or environment it affects.
- Material parameters: Show the amount, destination, content, permissions, or other values that determine the result.
- Reason and context: Explain why the agent believes the action is within the task, and surface relevant source information or uncertainty that could change the decision.
- Scope and reversibility: Make clear how much the action affects and whether it can be undone.
- Decision options: Offer approve and reject; where the system supports them, also offer edit, request more information, or stop.
Microsoft’s human-oversight guidance emphasizes intelligibility, traceability, and controls to verify, correct, override, or interrupt behavior. Its responsible-AI guidance says to require approval for actions that are hard to reverse or affect people, money, or compliance. The review-card details above are an implementation recommendation based on that guidance, not a vendor-prescribed checklist.
Keep human review meaningful
Prompting for every minor step can train people to click through without reading. Anthropic’s response to a NIST request for information on agentic security warns about “consent fatigue” when users face repeated per-action dialogs. It describes hundreds of actions in a session as an illustration of the risk, not as a measured statistic or prevalence estimate.
“When an agent is taking hundreds of actions per session, the risk is consent fatigue, where users habituate to clicking through approval prompts and the control stops providing the check it was designed to provide.” — Anthropic, response to NIST RFI on Agentic Security

Reducing unnecessary prompts can preserve attention, but only if the system continues to enforce high-risk boundaries. For lower-risk sequences, consider reviewing the plan, surfacing uncertainty, and flagging irreversible actions instead of asking for confirmation at every minor step. Keep individual approval where a person’s judgment is needed before a consequential action.
Implement approval as a workflow state
Approval is not just a dialog drawn over a tool call. The agent run must pause, the application must obtain a person’s decision, and the run must handle that response before the gated function executes.
Microsoft Agent Framework example
Microsoft’s Agent Framework documentation describes wrapping a function tool in an approval-required mechanism. A run can return an approval request instead of executing that function; the caller gets an approval or rejection from a person and passes the response back into the run. The documentation says to check for approval requests after each run until function calls have been approved or rejected. This is an example for that framework, not a claim that all agent platforms have the same workflow or defaults.
Verify the behavior of your platform
Microsoft’s Agent Safety guidance says that, in that framework, tools are invoked without user approval by default unless an approval mechanism is configured. Do not assume another platform—or a different configuration—behaves the same way. Check how your implementation handles retries, parallel tool calls, timeouts, queued actions, and resumed sessions. An earlier approval should not be treated as blanket permission for a later, materially different action.

When selecting an agent platform or comparing two designs, examine where enforcement happens and whether the workflow remains safe under normal operational conditions.
- Enforcement point: Is approval checked at the tool or action boundary, or is it only requested in instructions or a user interface?
- Granularity: Can rules distinguish reads from writes, resources, data sensitivity, transaction size, and reversibility?
- Review quality: Does the reviewer see the exact proposed action, parameters, context, and reason it was gated?
- Workflow behavior: Can a person reject, revise, or pause? Do pending approvals survive recovery and resume? Are parallel calls handled safely?
- Auditability and control: Can operators trace identities, decisions, tool calls, and outcomes, and interrupt work when needed?
- Operational burden: How often are people prompted, and are prompts focused on decisions where human judgment matters?
Maintain oversight after launch
Approval rules can become outdated as models, data, tools, usage, or regulation change. Microsoft’s responsible-AI guidance recommends deciding approval requirements during design, scaling preproduction review to the potential impact, and monitoring the system over time. It advises a responsible-AI assessment before production for agents that reach people or take important actions, with more thorough review for deployments affecting customers or money.
Make ongoing review part of operations, not a one-time sign-off. Track action traces, approvals, rejections, and escalations; review whether access remains necessary and whether people can assess prompts effectively. Alongside checkpoints, keep scope explicit, validate tool inputs, treat retrieved content and tool outputs as untrusted, bound loops, steps, and cost, and provide a way to interrupt work. No single prompt or review step replaces those safeguards.
