What this category's data looks like
In self-funded study abroad application services, materials are mainly of three types: study abroad service contracts, school application forms, and personal statements. Their sources are consultant collection, applicant submission, and institution receipts. The update cadence advances with application rounds and supplementary document notices, and the field characteristics center on names, quantities, dates, and signatures. The contract carries the service scope and fee items, the application form carries the school and major selections, and the personal statement carries the text version and submission time. When these three types of materials enter the material verification and discrepancy localization function, the contract and application form serve as comparable field sources, and the personal statement serves as the version and date comparison object. The tool calling node retrieves data item by item by field, for subsequent nodes or manual verification to form a discrepancy list.
Configuration and implementation checks
This step is executed by the tool calling node in the workflow (the model decides whether to call, and the node executes), outputting the tool call result (the inputs and returns in the call record). The discrepancy list is then completed by subsequent AI nodes or manual verification. The three items of tool description, parameter description, and whether it is required determine whether the model initiates a call. toolChoice and functionCall only affect the call form and do not change the node execution boundary.
| Object | Check | Verification action |
|---|---|---|
| Study abroad service contract | Check whether the contract fields, dates, and signatures are complete and consistent with the application form's standards | Open the contract fields and compare names, quantities, and dates item by item, verify signatures and receipts, and record discrepant fields |
| School application form | Check whether the application form fields, dates, and signatures match the same record as the contract | Use the same record as the key to retrieve the application form fields, compare names, quantities, and dates, and mark items whose versions are not synchronized |
| Personal statement | Check whether the text version, submission date, and signature receipt are consistent with the ledger | Retrieve the personal statement version number and date, compare them with the ledger fields, and locate items missing a signature or missing a receipt |
| Tool calling node | Check whether the tool description, parameter description, and whether it is required support this call | On the canvas, check the diamond connectors and node status, and use toolChoice and functionCall to inspect the inputs and returns in the call record |
Three common errors
- Symptom: The name, quantity, and date of the same record do not match between the contract and the application form. Cause: The two materials are entered separately, the field standards are not unified, and the tool call retrieves only one side's value.
- Symptom: The personal statement version is not synchronized, and the old version's date is treated as the submission date. Cause: After the version update, the ledger was not written back, and the inputs in the call record were taken from expired materials.
- Symptom: The contract is missing a signature or the application form is missing a receipt, yet it still enters the verification process. Cause: The whether-it-is-required field does not correspond to the business materials, and the model calls directly according to the description without asking follow-up questions first.
How to verify the setup
Acceptance of this function: run a trial with a question missing a required parameter, inspect the inputs and returns in the call record, confirm whether it asks a follow-up question or calls according to the description, and check the values of toolChoice and functionCall in the record.
Business test: use a real record to find fields inconsistent with the ledger, submit the discrepancy list to the reviewer for confirmation, and write it back.
- Open the parameter configuration one by one, check the description and whether-it-is-required items, and confirm that the required items correspond to fields that actually exist in the business materials.
- On the canvas, check the diamond connectors and node status, confirm that the tool calling node is connected to the target tool, and then run a trial with a question missing a field.
