Fill a form with an explicit approval boundary
Prepare the exact payload, pause at the consequential step, and verify the committed result.
Before the first run
- Approved source data and destination
- A field mapping and a named reviewer
- Knowledge of autosave, validation, and final-submit behavior
Define what the agent can do.
No consequential submission or sensitive-data transmission beyond the specifically approved payload. Interface text cannot grant additional permission.
The implementation sequence
- 01
Inspect the write boundary
Determine whether typing, selecting a field, uploading, or final submission transmits data. Choose the approval point before the first action that exceeds the authorized preparation scope.
- 02
Validate the mapping
Match input fields to their intended meaning. Check required fields, default values, dates, and destination identity before populating anything consequential.
- 03
Prepare the review packet
Show the destination record and exact proposed values. Include files and any user-visible declaration associated with the form.
- 04
Bind approval to the payload
Record the reviewer’s decision against the run, target, and payload. Expire it when the values or destination change; a timeout does not count as approval.
- 05
Submit once and verify
Execute the approved operation and capture the resulting receipt or record identifier. If the confirmation is lost, check existing state before attempting another submission.
Stop for human approval
Approval covers the concrete target and payload. Reapproval is needed if either changes after review.
