What the data for this category looks like
Engineering consulting supervision data mainly comes from project supervision logs, on-site inspection records, sub-project acceptance reports, cost accounting documents, and entrusted supervision contracts. The data update rhythm adjusts with project progress. Special supervision documents are updated weekly during the construction phase, and full sets of acceptance materials are updated synchronously during the completion acceptance phase. A single document’s structure includes a unique project identifier, supervision unit signature page, timestamp, rectification and closure list, and engineering quantity verification fields. Field units include square meters, ten thousand yuan, working days and other standard engineering units.
What constraints do these characteristics impose on the multi-turn dialogue and prompt engineering link
Engineering consulting supervision data is scattered across multiple types of special documents. Multi-turn dialogue needs to associate cross-document information such as supervision logs and acceptance reports from different phases. It must ensure the context window covers all associated data across the project lifecycle. Data update rhythms vary significantly across project phases, so prompts need to dynamically adapt to the document structure and field rules of the current phase. Engineering fields use specialized units, so the output of multi-turn dialogue must strictly match the unit format to avoid unit confusion. Single supervision documents are lengthy, so the context truncation logic for multi-turn dialogue must prioritize retaining core verification fields and rectification records.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Maximum context length | 8000–12000 characters | Matches the average length of single engineering documents, prevents core verification fields from being truncated |
| Number of retained multi-turn dialogue history | First 15 entries | Covers typical dialogue turns from project initiation to acceptance for supervision projects, retains key rectification instructions and feedback |
| Prompt variable configuration | Bind variables to project number, supervision phase | Automatically brings in exclusive fields for the current project, reduces manual input errors |
| Message response timeout | 120 seconds | Adapts to the recall and processing duration of large supervision project documents, prevents mid-interruption |
| Context recall limit | First 8 entries | Matches the number of associated documents for engineering data, avoids redundant information interfering with dialogue logic |
Three Common Mistakes
- Phenomenon: The AI-generated Markdown engineering progress table is truncated, with
...[hide X chardisplayed at the end. Cause: The maximum context length configuration was not adjusted, and long table content exceeded the preset window and was forcibly truncated. - Phenomenon: After the client closes the SSE connection, the supervision rectification records from this conversation are not saved to the database. Cause: The
chatIdpersistence logic was not configured, and context writing was not completed when the conversation was interrupted. - Phenomenon: The conversation returns the error
insufficient_quota Upstream load of the current group is saturated, please try again later. Cause: The message response timeout was not set, or the timeout configuration was too short, leading to a backlog of concurrent supervision consultation requests that triggers load restrictions.
How to Confirm Proper Configuration
- Initiate a consultation involving engineering-specific units, and verify that the units in the output match the preset field rules.
- Simulate a multi-turn dialogue, send supervision questions from different phases in sequence, and check whether the context correctly associates historical conversation content.
- Manually interrupt the SSE connection, and check whether the
messagesrecords of this conversation are fully saved in the database. - Upload test supervision documents, and check whether the recalled context covers core verification fields.
