What the documents look like
For document comparison in Amazon FBM fulfillment, this page examines FastGPT tool calls. Compare the material received with the sources used in the answer. The examples are hypothetical.
Constraints at the tool calls step
An FBM transaction comparison can examine the stages described by shipment confirmation and tracking material. Proposed inputs include those passages and order correspondence while lacking customer receipt evidence. Describe the tool as reading records from different stages, retaining source identities rather than turning confirmed dispatch into delivery. A return-address setting defines an address arrangement without replacing receipt evidence for this order.
Configuration and implementation checks
| Check | Proposed material or condition | Evidence to inspect |
|---|---|---|
| Recorded stages | Dispatch separate from transit progress | Not collapsed into delivered status |
| Source status | Service retelling replacing carrier evidence | Inspect provider and obtain the source |
| Difference timing | Passages describe different moments | No breach inferred from wording alone |
| Receipt gap | Customer receipt evidence absent | The answer retains that unknown |
| Operation receipt | Separate refund or replacement handling | Actual results verified independently |
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
A request may substitute a customer-service retelling for a carrier record even when document labels look complete. Inspect the passage and provider, identify reported statements and obtain the corresponding source. Another failure labels dispatch and in-transit wording as a contradiction. Inspect their stated times and stages before comparing the same moment; different wording alone does not establish seller breach. If a return-address setting becomes warehouse receipt of returned goods, inspect the location rule separately from this receipt record. Where an item may be sent differs from what was received; retain the gap without this instance’s evidence.
How to verify the setup
Retain source status, timing and the absent receipt evidence, tracing actual tool input and cited differences without collapsing stages into a final outcome. Missing suitable required inputs may prevent a call; collect passages through interaction and retest without assuming automatic follow-up. Termination leaves no subsequent AI summary of this call. Shipment updates, refund entries or replacement procurement require separate business permission and receipts; comparison output is not execution evidence.
