/ THE SHORT ANSWER
- 01Separate drafting authority from spending authority.
- 02Protect the commitment tool independently of the model.
- 03Design retries and rollback before enabling writes.
/ dotSuper point of view
An agent becomes an operational system when its permissions, commitments, and recovery paths are designed as carefully as its recommendations.
Define the commitment before the conversation
An agent connected to an ERP may create an order, alter a delivery date, or accept a supplier substitution.
Those actions can create obligations that outlast the conversation that triggered them.
NIST's Generative AI Profile is a companion to its voluntary AI Risk Management Framework.[
1] Our implementation recommendation is to translate risk discussion into concrete permissions.
Name the business actions the agent can perform and the conditions under which it must stop.
Start with one narrow task, such as preparing a replenishment draft for approved materials.
Describe the intended output and prohibited actions.
Avoid granting broad procurement access merely because the integration connector offers it conveniently.
Keep tool authority outside the model's judgment
The model can explain why it wants to act, but that explanation should not override the authorization rule.
NIST's zero trust guidance treats authentication and authorization as explicit functions and rejects implicit trust based on location or ownership.[
2] Applied to an agent, the principle supports distinct identities and scoped access.
It does not make an agent trustworthy simply because it runs inside the company.
Use separate permissions for reading prices, editing drafts, and issuing commitments.
Restrict the records returned by search to the task's scope.
A purchasing agent handling office supplies should not automatically see defense drawings, employee records, or unrelated customer pricing.
Write an action policy people can understand
Describe each permitted action in business terms.
A nontechnical owner should be able to tell whether a proposed supplier change is allowed without reading the agent's prompt.
Treat incoming supplier documents as information, not instructions.
A quotation containing text that tells the agent to bypass approval should not change its authority.
The integration should enforce policy even when the model follows misleading content.
Design a stop mechanism that blocks new commitments while preserving evidence.
Specify who can invoke it and what happens to queued work.
A stop button that merely closes the chat window may leave background actions running.
| Action | Recommended gate |
|---|---|
| Read stock | Task-scoped records and access controls |
| Suggest supplier | Approved supplier evidence |
| Create draft | Validated fields and stable operation key |
| Change quantity | Policy limits and current business state |
| Commit order | Required human approval and tool authorization |
| Retry or recover | Check prior result before another write |
Worked hypothetical: a retry that creates a duplicate
The purchasing system accepts the draft but the response times out.
The agent cannot tell whether the request succeeded and tries again.
Without a stable operation identifier, the second request could create another draft or order.
The proposed design uses a unique business operation key and checks the existing result before repeating a write.
Finance still controls any required approval before commitment.
The example demonstrates a failure condition, not a real test result.
Its acceptance criterion is concrete: a timeout and retry should leave one intended business action with an explainable status.
The team can evaluate that behavior before enabling wider use.
Evaluate failures that ordinary demos avoid
Include a user who changes the request midway.
The correct response may be to ask for review or stop.
Measure completed correct tasks, unauthorized-action attempts blocked, unresolved exceptions, and recovery effort.
A high completion rate is not useful if exceptions are silently converted into guessed commitments.
Keep the evaluation set tied to the real workflow.
Record the input references, proposed action, policy decision, approving person, tool result, and final business state.
Avoid storing unnecessary sensitive content in logs.
The aim is enough evidence to reconstruct the action without creating a new uncontrolled data store.
Expand authority only after the operating case improves
Compare review time and error handling with the existing process.
More autonomy is a design option, not the definition of success.
When considering write access, identify the specific bottleneck it would remove.
Confirm that the relevant policy controls, timeout handling, and incident ownership exist.
Give procurement a way to pause the agent during unusual supplier or inventory conditions.
The first deliverable should be a permission map and executable acceptance cases for one task.
Those artifacts turn an appealing demo into a reviewable business system.
Expand only when the next permission has a clear purpose and a failure path the company can manage.
What this page cannot conclude
- 01The proposed architecture is an original design recommendation, not a NIST-certified implementation.
- 02The example does not demonstrate a tested agent or guaranteed prevention of unauthorized commitments.
