What the documents look like
Tmall flagship store operations handle contract and transaction material comparison across four recurring document types: product publishing pages, brand authorization letters, delivery commitment records, and after-sales work orders. These documents arrive from the Tmall merchant backend, the Tmall rule center, ERP order tables, and customer service chat logs. Brand authorization, flagship store identity, and Tmall points compensation rules make authorization subject, commitment period, and compensation conditions central fields that must be checked for consistency. The supplied brief lists daily and per-order update frequencies; this page does not extend those into batch synchronization, real-time triggering, or full synchronization mechanisms.
The comparison task operates on the same subject, the same period, and the same field. A delivery commitment on a product publishing page, the valid range of a brand authorization letter, and a handling request in an after-sales work order cannot be judged contradictory when their field definitions differ. The context and token step determines how much source material, how much prior conversation, and how much knowledge base reference content a single comparison request can carry; content beyond those limits is trimmed before the request is sent.
Constraints at the context limits step
The maximum context of a model sets the content length a single request can reference. The reply limit only restricts output length; the two must not be treated as interchangeable. Memory rounds control how many earlier chat rounds are referenced, and a larger value makes it easier to carry earlier conversation while increasing consumption. The knowledge base reference limit controls, by token, the maximum content referenced per search, so a long single passage may be trimmed. Enabling question optimization adds one model call before formal retrieval, which may improve retrieval across consecutive follow-up questions and also increases overall time.
Hypothetical drill sample: a flagship store operator intends to check whether the authorization period on a brand authorization letter matches the product publishing page. The authorization letter reads: "Authorizing party A authorizes the subject B flagship store, authorization period 1 January 2024 to 31 December 2024, authorization scope limited to product publishing and sales in this store." The product publishing page reads: "The brand authorization for this store is valid until 31 December 2024." The draft sentence to be judged reads: "The store's brand authorization remains valid for all of 2024 and product publishing may continue." The comparison request reads: "Determine whether the publishing page commitment and the authorization letter are consistent, and state the basis." This sample only illustrates the context and token checking method and does not represent any real authorization relationship.
Configuration and implementation checks
The table below addresses this sample and lists documented settings or implementation checks tied to this feature and primary task. Numeric starting values are hypothetical drill starting points for this exercise, with the reason for the choice and the comparison object stated; they are not official default values.
| Configuration item | Hypothetical drill starting point | Check method and reason |
|---|---|---|
| AI model | Select a model whose maximum context covers the sample | Read the maximum context in the model information and compare it with the combined length of the sample material and draft sentence to confirm no trimming |
| Memory rounds | Set to 2 rounds for this drill | The sample is a single comparison, so a small amount of history suffices; compare with 0 rounds to observe whether unrelated conversation is carried in |
| Reply limit | Set high enough to hold basis and conclusion | Enable the reply limit and set a length, then compare with the explanation length the draft sentence requires to confirm the reply is not cut short |
| Knowledge base reference limit | Set to cover both the authorization letter and the publishing page | Reference is controlled by token; compare with the combined length of the two passages to confirm key fields are not trimmed |
| Minimum relevance | Keep default for this drill and record the value | This value applies only under semantic retrieval or result reranking; compare with the sample retrieval result to observe whether the authorization period field is filtered out |
| Reply format | Keep default for this drill | The sample needs a text conclusion only, with no fixed structure; switching to json_schema would require filling in format requirements and verifying field completeness |
Three common errors
- Treating the reply limit as the full context window. The reply limit only restricts output length, while the maximum context determines the content length a single request can reference. If the two passages plus the draft sentence in the sample exceed the maximum context, the authorization period field may be trimmed before the request, and the comparison conclusion loses its basis.
- Treating a retrieval result as proof of authorization status. Knowledge base retrieval only returns reference content; it does not verify whether the authorization letter is genuinely valid, nor whether the publishing page commitment has been authorized. Retrieving the authorization letter text in the sample does not support a conclusion that authorization has taken effect or that publishing has been approved.
- Treating a pending review request as granted authorization. The comparison request in the sample is in a pending-judgment state; being under review does not indicate a lack of operating permission, nor does it indicate that authorization has been approved. Signing, reaching cooperation, and contract effectiveness are three distinct facts; when the sample does not state an effectiveness clause, whether authorization has taken effect remains unsupported.
How to verify the setup
- Enter the authorization letter text, the publishing page text, and the draft sentence from the hypothetical sample above, then compare the content actually received by the model with the two source passages. If the authorization period field appears completely in the request content, the reference limit and maximum context are sufficient for this sample; if the field is missing, record it as trimming and do not judge it as a material contradiction.
- Enter the same sample and set memory rounds to 0 and then to 2, comparing the history content carried into each request. If 2 rounds carry conversation unrelated to the authorization period and affect the conclusion, record it as context interference; if both conclusions match, the sample is not sensitive to history rounds.
- Enter an empty reference result, that is, the paper input [], and check the downstream node's design for handling the absence of reference content. Observe whether the downstream gives a no-basis notice or routes to a human, without claiming that a fictional rule search necessarily returns []. This check confirms that an empty-result branch exists and does not indicate that retrieval is necessarily empty.
- Enter the sample draft sentence and compare how the reply states the three fields of authorization period, authorization scope, and effectiveness status. If the reply turns "authorization period until 31 December 2024" into "authorization has taken effect," record it as field confusion; if the reply clearly separates period from effectiveness status and notes the evidence gap, the check condition is met.
The documented technical facts used to identify relevant content in the documents are: model context should be checked against actual model capability and the reply limit is not the full context window; reply length should be adjusted for the task while retaining enough content to express basis and handling action; the knowledge base reference limit is controlled by token and should be checked against single-passage length and the question sample for trimming; historical input should be checked by comparing the same question under empty history and with history to rule out context differences; when a fixed reply format is used, field completeness and parsing success must be verified rather than checking text length alone.
