What the documents look like
For copy drafting in Export tax rebate filings, this page examines FastGPT context limits. An export-document reminder can organise missing items without converting its checklist into a review decision. The examples are hypothetical.
Constraints at the context limits step
A proposed export-document checklist lacks the cover page in its originals directory. A handover note asks the business party to supply it before sending material for checking. Another, historical case has a complete-file note. The current reminder can identify the missing page without deciding an actual filing outcome or borrowing completeness from the old case. Actual context needs the missing object, responsible party and subsequent action together. A filing-related heading supplies no evidence that submission or approval has already happened for the current materials.
Configuration and implementation checks
| Material check | Conditions in this test | Implementation evidence |
|---|---|---|
| Missing item | Cover page | Trace actual request. |
| Action order | Supplement before checking | Inspect completion tense. |
| Supplying party | Business party | Retain named actor. |
| Historical state | Different complete case | Check case and version. |
| Actual outcome | Not supplied here | Make no review decision. |
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
First, a draft may shorten send after supplementation into already sent; compare the memo with output for action sequence. Second, input trimming may remove the missing cover; trace complete checklist, reference content and request to locate that loss. Third, historical completeness may migrate into this case; inspect case identity and document version using generation without that history. These test stage, input coverage and case ownership. A longer reply cannot create the current original page, establish completion of a subsequent action or supply a reviewer’s decision absent from the proposed sources.
How to verify the setup
Require the reminder to say what is missing, who supplies it and what follows, tracing each sentence to current request material. Separate reference volume and reply length from actual model context capacity. A later cover requires the same-case identity check before revision. This exercise files nothing, decides no tax eligibility and gives no actual procedural requirement; its fictional gap is not an official mandatory-document list. Missing checking evidence marks only the present source gap. Failure to retrieve it does not establish that real checking never occurred or that the actual business must fail.
