Before an AI Agent Resumes, Recheck the Work

A customer support agent prepares a replacement order and pauses for a manager's approval. While it waits, the customer changes the delivery address. The manager then approves the original request.

The agent resumes with its earlier working state intact. It still has the old address, a prepared order, and an approval attached to that version. Continuing immediately could send the replacement to the wrong place.

This hypothetical case illustrates a decision every business needs to make before adopting agents that can pause and return to work: what must be checked again when they wake up?

New infrastructure makes waiting a design decision

On October 22, Google Cloud announced Agent Compute Engine, describing infrastructure that can pause an agent's execution environment while it waits and restore it from a snapshot. Google says the service already supports its own agent workloads and is targeted for customer preview in the coming months. The announcement is not general availability for custom agents.

Google's technical explanation describes preserving working state through checkpointing and maintaining persistent user workspaces. These are vendor descriptions. We have not independently tested the implementation or its performance claims.

Our operating implication is straightforward: preserving a computer's state does not establish whether a proposed business action is still appropriate. A saved workspace can restore the work that was prepared. The workflow still needs a decision about whether that work remains valid.

Identify what can change during the wait

Start with one workflow that pauses for a person or an external system. List the facts the next action depends on, then identify which of those facts could change before execution.

For the replacement order, the relevant facts include the current delivery address, whether the request remains open, and whether another employee has already handled it. A change to an unrelated customer note may have no bearing on the shipment. A changed destination does.

Give each important condition an authoritative record and an owner. Record when it was checked and which version supported the prepared action. Avoid treating a conversation summary as the final authority for a mutable operational fact.

This extends the discipline behind keeping agent memory current to a specific moment: the transition from waiting to acting. The aim is to refresh the evidence needed for the next decision without rebuilding every completed step.

Make approval depend on the actual action

An approval should identify what the reviewer saw. In the example, that means the replacement item, destination, customer request, and relevant conditions. Keep the approved version with the approval record.

If a material field changes during the wait, the workflow should mark the earlier approval as requiring review. Define material changes with the business owner. A corrected internal label might be harmless; a new recipient or delivery address could change the decision.

Show the reviewer what changed and why another decision is needed. Do not make them reconstruct the difference from a long agent transcript. Also define how an approval expires or is withdrawn, and who receives the case if the original reviewer is unavailable.

The policy should be proportionate. Requiring a fresh approval for every harmless update creates delay and encourages reviewers to approve without reading. Decide which changes affect the commitment, then enforce those conditions consistently.

Close the gap between checking and writing

A fresh check can still become stale before the next action completes. In the example, an employee could amend the request after the agent reads it but before the replacement order is created.

Where the receiving system supports it, have the integration submit the expected record version or required condition with the action. The system should reject a conflicting change so the workflow can refresh and reassess. A prompt telling the model to be careful cannot provide that guarantee.

Also check whether the action already happened before repeating it. A connection failure can leave the agent without confirmation even when the receiving system completed the request. Reconcile the actual order record before creating another replacement, using a stable request identifier where supported.

Some integrations cannot enforce these checks directly. Make that limitation visible. For consequential actions, the business may need a controlled queue or human execution step until the integration can handle conflicts reliably. Treat that as an operating cost when comparing platforms.

Test changes that happen while the agent is asleep

A demonstration that pauses and resumes successfully proves only part of the workflow. Test what happens when the underlying case changes during the pause.

Use approved test records to change the address, withdraw the request, remove the approver's authority, and complete the replacement through another channel. Confirm the expected response for each case before running the tests. The agent should continue, seek a revised approval, or stop according to that decision.

Keep evidence of the original proposal, the later record, and the action ultimately taken. Include interrupted responses and repeated wake-up signals so the team can see whether recovery creates duplicate work.

Measure safe completion after the wait

Assign one owner to the resumed workflow and its exceptions. Track how often a return to work requires refreshed evidence, renewed approval, or manual reconciliation. Measure the time to an accepted outcome, including the review burden.

Use the exception path to make unresolved conflicts visible to someone who can act. A waiting case needs a clear status and next owner even when its compute environment is inexpensive to preserve.
