What the documents look like
For document comparison in Shopify fulfillment, this page examines FastGPT context limits. Cabinet handover downstairs and carrying indoors require distinct service scopes. The examples are hypothetical.
Constraints at the context limits step
A proposed Shopify service note says the cabinet is handed over downstairs and indoor carrying is to be discussed separately. A communication remark says doorstep delivery as last time, but the earlier order is absent. An indoor-service question needs downstairs, indoor carrying and the separate-discussion condition together in current input. Doorstep is undefined shorthand here and cannot replace the explicit downstairs handover. The missing earlier order also cannot prove that carrying was never discussed; it identifies confirmation unavailable in the current packet rather than settling the complete transaction history.
Configuration and implementation checks
| Context review subject | Specific text condition | Acceptance evidence |
|---|---|---|
| Current location | Downstairs handover | Check full location wording reaches input. |
| Additional service | Indoor carrying discussed separately | Retain condition and confirmation action. |
| Historical shorthand | Doorstep is undefined | Do not replace the explicit location. |
| Subject reference | Accessory and cabinet may be confused | Compare current subject and history. |
| Case handoff | Location, service scope and unresolved item | Inspect actual format and parsing. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Model context | Use the actual model’s accepted context scope. |
Reply length | The reply limit differs from the context window. |
Knowledge-reference limit | Knowledge citation limits are token-based. |
History-input check | Compare empty-history and populated-history inputs. |
Structured-output handoff | Validate parsing, then inspect support for field values. |
Three common errors
One error is a citation losing the handover condition while the answer fills it from historical conversational shorthand. Another risk is a pronoun previously referring to an accessory being reassigned to the whole cabinet, carrying the service scope with it. Compare actual input subjects, locations and references rather than response fluency. Record missing source wording separately from imported historical objects. Actual context capacity and reply limits require separate checks; increasing reply length cannot recover a handover condition that never reached the model input in the first place. A third error transfers carrying terms from an earlier order to this transaction. Inspect an explicit applicability relationship between orders, beyond the doorstep wording. The same buyer and cabinet cannot by themselves establish that the service terms carry over.
How to verify the setup
Acceptance can ask whether the available wording includes carrying the cabinet indoors, first without history and then with the doorstep remark. The output should preserve the downstairs sentence, the indoor-carrying qualification and the confirmation still required, rather than reducing the comparison to an unqualified yes or no. If a fixed format feeds a service case, verify that location and follow-up action are present and parsed. A later-obtained earlier order still needs an explicit applicability relationship to this transaction; a shared buyer alone cannot transfer its service scope.
