What the data for this category looks like
This category of data primarily comes from internal permission-controlled file servers, OA systems, and classified document libraries of central state-owned enterprises, government agencies, and public service institutions. Data update cycles align with internal system revision processes. Data is synchronized in real time or on a regular basis alongside official document issuance or permission adjustments. Document formats are mostly PDF and Word files with chapter numbers and permission markers. Some entries are structured business data tables. Data fields include file unique identifier, access permission level, publishing department, and upload time. The basic statistical unit is a single permission-controlled file.
What constraints these characteristics impose on multi-turn dialogue and prompt engineering
The permission level field requires multi-turn dialogue to bind the user's chatId and corresponding access permission identifier. This prevents cross-permission access to unauthorized file data. The chapter numbers and permission markers distributed across structured documents require prompt engineering to clearly specify the file scope for context matching. This avoids content confusion across chapters or permission groups. The data update cycle requires multi-turn dialogue context cache to synchronize the latest versions of permission-controlled files on a regular basis. This prevents returning expired content. The complex formatting of unstructured documents requires prompt engineering to include format validation rules. This ensures parsed segments align with dialogue logic.
Configuration Guidelines
These configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chatId binding configuration | Bind user permission identifiers and session IDs | Ensure each dialogue round only accesses file data within the corresponding permission scope |
messages context window | 8000–12000 token, calibrated via actual testing | Adapt to the single-round parsed segment length of permission-controlled files, avoid exceeding model capacity limits |
| Permission validation switch | Enabled | Filter knowledge base data using user permission fields in variables |
| Context refresh cycle | Every 24 hours | Align with the regular update rhythm of internal systems, return the latest version content |
| Multi-turn history retention count | First 10 entries | Limit context redundancy, ensure prompt engineering logic is clear |
Three Common Misconfigurations
- API upload of permission-controlled files returns parsing failure with status code 403. This occurs because
chatIdand the user's permission identifier are not bound, triggering the built-in permission isolation validation logic. - Answers tested via the platform frontend differ from results returned by API calls. This occurs because the API request does not carry user permission fields in
variables, leading to unfiltered knowledge base retrieval scope. - Newly created dialogue applications default to associating all non-permission-controlled files. This occurs because the permission validation switch is not enabled, and the configuration does not restrict access to only permission-controlled file data.
How to Verify Proper Configuration
- Initiate a multi-turn dialogue, check that each request carries
chatIdto ensure consistent session context. - Review API request logs, confirm that user permission fields in
variableshave been correctly passed for knowledge base data filtering. - Conduct cross-user dialogue tests, verify that users with different permissions cannot access each other's permission-controlled file data.
- Wait for the configured refresh cycle, then initiate a dialogue to confirm returned content is the latest version of permission-controlled file data.
