What the Data for This Category Looks Like
Urban water services business data is sourced from official business systems of local urban investment water groups, covering application-related services such as water supply installation, drainage permit application, water fee inquiry, repair and complaint handling. Data updates are triggered in accordance with business process adjustments, with a routine maintenance cycle of once per quarter. The document structure is split by major business categories, each containing modules such as application conditions, required material list, handling process, and consultation contact information. Structured information fields include business code, handling time limit (unit: working days), material format requirements, and charging standards (unit: yuan/cubic meter or yuan/item).
Constraints Imposed by These Characteristics on Multi-turn Dialogue and Prompt Engineering
The structured classification of water services business data requires multi-turn dialogue to first identify the user's specific business type, to avoid confusion across different business processes. Units in fields (such as working days, yuan/cubic meter) must be strictly corresponding in dialogue, and cannot be converted arbitrarily. Historical work orders and user consultation records involve privacy information. One must perform permission filtering through the variables parameter, only returning content that the user can query on their own. The step continuity of business handling processes requires multi-turn dialogue to guide users through links such as material submission and condition confirmation in order, and steps cannot be skipped.
How to Configure the Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Generated based on the unique serial number of the user's water services business handling | Associates with the user's exclusive business records, maintaining dialogue consistency in the same scenario |
messages | Limit the context to the first 3 rounds of dialogue | Water services business processes have clear steps; excessive historical information will interfere with guidance for the current link |
variables | Inject handling time limit and material list fields of the current business | Combines structured data of water services to accurately respond to users' specific inquiries |
| Session expiration time | 7 days | Matches the general configuration CHAT_FILE_EXPIRE_TIME=7, adapting to the handling cycles of most water services businesses |
| Multi-turn guidance trigger threshold | Calibrated based on actual testing | Adjust according to the complexity of water services business, avoiding overly frequent or missing guidance |
| Context recall count | First 2 rounds of historical dialogue | Reduces redundant information, focusing on the current water services business handling link |

Three Common Configuration Mistakes
- Phenomenon: The dialogue interface returns abnormal token billing. Cause: The context rounds of
messagesare not limited, and all historical dialogue is included in each call, resulting in unexpected excessive invalid token consumption. - Phenomenon: 7 days after a session expires, users cannot retrieve their historical water services business consultation records. Cause: The session expiration time parameter is not adjusted, and the default 7-day setting is used, which cannot cover some cross-cycle water services business handling processes.
- Phenomenon: Batch execution of multiple AI dialogue nodes causes result crossover. Cause: Users do not assign independent
chatIdto each dialogue task, resulting in confusion of context data across different businesses.
How to Confirm Configuration Correctness
- A user initiates multi-turn consultation for the water supply installation business, and checks that the returned handling time limit and material list are consistent with official document content.
- A user re-enters the same session after 7 days, and confirms that historical dialogue records can be retrieved, verifying that the session expiration time configuration meets expectations.
- A reviewer reviews interface call logs, and confirms that water services business fields injected in
variablesdo not contain user privacy information. - A user initiates multiple parallel water services business consultation tasks, and checks that the dialogue context of each task is independent and results have no crossover.
