What This Category of Data Entails

Typical users of this category include customer success managers, training instructors, and product operations teams. Daily deliverables include training slides, user manuals, training attendance sheets, and Q&A checklists. Data sources primarily include product help centers, customer organizational structures, training recordings, and ticketing systems. Update frequency follows per order or per version cycles. The most time-consuming daily tasks focus on role permission explanations, operation step demonstrations, and post-class question organization. Improper handling can lead to customers failing to get started with the product, reduced onboarding conversion rates, and a sharp increase in ticket volume. This category focuses on building customers' first-time usage capabilities, and has clear differences from businesses related to renewal health management.

Constraints Imposed on Multi-turn Dialogue and Prompt Engineering

The multi-source nature of this category's data requires multi-turn dialogue to link product help center content, customer organizational information, and historical tickets. This ensures responses align with actual customer scenarios. Updated per order or per version, prompts must adapt to operation logic after version iterations to avoid outdated content. Role permissions and operation steps are core Q&A topics. Multi-turn dialogue must focus on these subjects, limiting delivery of non-essential information. The risk of sharp ticket increases requires controlling reasonable context length for dialogue, avoiding loading excessive redundant historical records. It also requires pre-judging high-frequency questions to reduce resource consumption from repeated Q&A.

Configuration Settings

This configuration is based on FastGPT v4.17.0.

Configuration ItemRecommended ApproachRationale
Maximum ContextFirst 20 turns of dialogue + 800–1200 charactersMatches single-page content length of training documents, avoids exceeding the information range that the model can process
Question OptimizationCalibrated based on actual testingAdapts to colloquial questions in training scenarios, translates phrases such as "how to enable administrator permissions" into standard operation step queries
variablesBind current training version number, customer organization fieldsInject business-specific data via the variables parameter, ensuring responses match the customer's actual organizational structure and product version
chatIdBind single training sessionLinks historical Q&A records within that session, avoids repeating answers to similar questions in the same training segment
messagesFilter thinking process fieldsRemove internal model thinking content from the messages parameter, only retain user questions and formal responses
Single Reply LimitFirst 3 operation stepsCorresponds to the most time-consuming operation step demonstration segment, avoids outputting excessive information at once and confusing customers
Timeout Threshold600 secondsAdapts to the processing duration of complex questions in training scenarios, avoids session interruption due to prolonged waiting

Three Common Configuration Errors

  • Displaying model thinking processes in dialogue history, which interferes with customer questions. Cause: The thinking process field was not filtered from the messages parameter, resulting in full inclusion of historical records.
  • Failing to trigger directory reading operations after integrating code execution tools. Cause: No binding of code execution permission explanations for training scenarios in the prompt, leading to a disconnect between tool call logic and training content.
  • Slower model response speed with no clear error message. Cause: The context length of the messages parameter was not limited, resulting in loading excessive historical training records with each dialogue and consuming computing resources.

How to Verify Correct Configuration

  • Initiate simulated training questions, check if responses include operation steps for the current version, with no redundant irrelevant content.
  • View the session history bound to chatId, confirm that only valid user questions and formal model responses are retained, with no thinking process fields.
  • Test code execution tool calls, confirm that the trigger logic matches the permission explanations in the training documents.
  • Initiate consecutive multi-turn questions, check that response speed does not show a significant decline.
