Identify what the proposed release changes
Record the current and proposed versions of the application, instructions, model configuration and document collection where relevant. State the business reason for the change and the tasks most likely to be affected. If several components change together, identify them rather than calling the release a model update. Keep the comparison environment and test accounts consistent enough that reviewers can distinguish a release effect from an unrelated source or permission change.
Choose tasks with different failure consequences
Include frequent questions, important exceptions and cases that previously failed. Add questions with missing information, conflicting sources and requests outside the assistant agreed scope. For each case, write the expected behaviour and why it matters. Separate convenience issues, such as an awkward summary, from release-blocking issues defined by the team, such as exposing a restricted record or claiming an action completed when it did not.
Judge the result rather than identical wording
Define checks around required facts, appropriate sources, missing qualifications and permitted actions. Two useful answers need not contain the same sentences. Specify when the right response is to ask a clarification or refer the task to a person. Where repeated runs are part of the review, agree that approach before testing and retain all results. Do not select only the most favourable answer as the evidence for a release.
Review differences with the task owner
Give the reviewer the original request, relevant approved source and both outputs. Ask them to mark a difference as acceptable, an improvement or a problem, with a short reason. Keep unresolved cases separate from passes. If the proposed release uses a newer source, explain that change rather than scoring the old answer as the permanent truth. Assign technical failures to an engineer and business interpretation questions to the relevant source owner.
Walk through a fictional procedure change
A fictional distributor changes its assistant instructions to produce shorter answers. A regression case asks how staff handle a damaged delivery. The new answer is shorter but omits the required supervisor review in the approved fictional procedure. The task owner rejects that case, the team revises the instructions and repeats it alongside other procedure questions. The test checks preservation of the required step, not whether the response matches a particular paragraph.
Prepare the release and reversal record
Record who accepts the remaining differences and which failures prevent release. Identify the previous working configuration and have the technical owner confirm how it can be restored, including any changed data or integrations that need separate treatment. After release, review a controlled sample of supported tasks and incoming issues. Reopening a failed case should trigger an owned decision about correction or reversal, rather than silently editing the acceptance criteria.
