Missing fields need a workflow, not a creative answer
Design extraction so uncertainty becomes a request for clarification rather than invented data.

Absence is useful information
An intake assistant can be valuable precisely because it notices what is not present. Define required fields by the next business step, not by a desire to fill every database column. In an illustrative service request, a missing location may block dispatch while an optional reference note can wait. The model should preserve that distinction rather than infer a location from the customer’s previous message.
Separate extraction and enrichment
If a system is allowed to enrich a record from an approved customer database, label that action separately from extraction. Keep the source and timestamp for the enriched value and ask whether confirmation is required. A value printed in a document and a value retrieved from an account profile have different evidential status. Blending them into one unmarked response makes disputes and corrections unnecessarily difficult.
Workflow at a glance
Build the clarification queue
Use an explicit status such as awaiting information, assign an owner, and state the exact question that remains. Do not send an automatic email merely because the model drafted one; the initial pilot should use approved templates and an agreed review rule. Measure time from detection to resolution. This focuses the project on reducing unresolved work instead of celebrating a high volume of extracted drafts.
Test the refusal boundary
Create test examples with unreadable text, absent fields, conflicting addresses, and plausible but wrong defaults. A successful system asks for clarification when the evidence is insufficient. AWS human-review documentation illustrates routing based on missing keys; your implementation still needs ownership and clear business rules. Review the exceptions weekly and improve the intake form where the same omission repeatedly appears.
A missing-information rehearsal
Submit a synthetic request with one critical field absent. Follow it through detection, assignment, clarification, correction, and release. If nobody can explain who owns the waiting state, the workflow is incomplete even when the model reliably detects the missing field.
Service availability
The cited A2I documentation currently states that the service is no longer open to new customers. It is included as an example of a human-review pattern, not as a deployment recommendation. New implementations must verify available alternatives and their operating constraints.
