What the documents look like
For document comparison in Certificates of origin, this page examines FastGPT tool calls. Origin-document tools compare goods identity, clauses and issuance evidence without deciding approval. The examples are hypothetical.
Constraints at the tool calls step
Suppose a contract identifies a supplier only, origin wording awaits supplier information and an application acknowledgment records receipt only. Limit the tool description to organizing this batch, requiring correspondence among contract, goods and application. Check system parameters separately from plugin configuration, connect the calling module and inspect the actual request. Missing required correspondence may prevent invocation. No real issuance outcome or legal decision is supplied.
Configuration and implementation checks
| Origin-comparison tool | Hypothetical material | Check |
|---|---|---|
| Supplier identity | Limited role | Not manufacturing origin |
| Origin wording | Information pending | List evidence gap |
| Application received | Not issued | Real certificate |
| Older wording | Other goods | Current-batch correspondence |
| Formal determination | Responsible process | Authority and evidence |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Tool description | Describe purpose, inputs and non-applicable situations. |
Tool parameters | Inspect module and plugin parameters separately. |
Required parameters | The model may not invoke a tool without suitable required inputs. |
Tool connections | Available tools must connect to the calling module. |
Tool-call termination | Termination ends the call without a later AI summary. |
Three common errors
Supplier identity reported as manufacturing origin needs roles and origin evidence checked. Received application reported as issued certificate needs issuance evidence checked. Older-batch wording applied here needs goods identity checked. These concern roles, stage and ownership; a tool name or successful return establishes no origin fact.
How to verify the setup
Trace input, invocation parameters and response item by item, keeping missing origin evidence beside relevant goods. If calling terminates, inspect terminal output without expecting a later model summary. Added supplier wording supplies review material alone. Formal determination, application handling and business writes need responsible processes and authority. The tool lists support, conflicts and gaps for a reviewer. Separate supply and manufacturing roles, matching issuance evidence to this batch instead of filling gaps from an application title.
