What the data for this category looks like
The policy and regulatory basis data for engineering consulting supervision mainly comes from industry norms, bidding management measures, on-site supervision regulations issued by the Ministry of Housing and Urban-Rural Development and provincial housing and urban-rural development authorities, as well as internal supervision project management systems of state-owned enterprises and public sector entities. The data update rhythm is as follows: national-level norms are revised every 3 to 5 years, local supporting detailed rules are updated every 6 months to 1 year, and internal management systems are adjusted synchronously every quarter. Each individual document includes fields such as document number, issuing authority, effective date, scope of application, core clauses, penalties, and others. Document lengths range from several hundred-word notices to tens of thousands-word comprehensive management measures, and all fields follow clear standard formats.
What constraints these characteristics impose on the "tool calling and plugins" workflow
Since policy data sources are scattered across three categories: national-level, local-level, and internal enterprise sources, tool calling must be configured with multi-source retrieval plugins to cover the full data scope. Document fields include clear effective dates and document numbers, so tool calling must support filtering by these fields to avoid returning outdated or inapplicable policy content. The length of individual documents varies widely, so tool calling must adapt to long-text segment parsing and extraction to ensure complete return of core clauses. Different data sources have different update rhythms, so plugins must regularly refresh indexes to ensure the timeliness of called data.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale for This Setting |
|---|---|---|
toolChoice | auto | Automatically select tools adapted for supervision policy retrieval, compatible with multi-source data calling scenarios |
functionCall | ["retrieve_policy", "filter_by_effective_date"] | Specify tool functions for policy retrieval and filtering by effective date, matching the field requirements of supervision policies |
| Single Search Limit | Top 10 entries | The number of engineering consulting supervision policy documents is moderate; the top 10 entries can cover core basis and avoid redundant results |
| Query Optimization | Enabled | Convert user questions in supervision scenarios into standard policy retrieval keywords to improve retrieval accuracy |
| Maximum Context Length | 8000 token | Policy documents are usually lengthy; 8000 tokens can accommodate complete core clause content, adapting to the context requirements of tool calling |
| Plugin Response Timeout | 60 seconds | Multi-source retrieval requires pulling data across sources; 60 seconds covers most retrieval scenarios and avoids premature timeouts |
Three common misconfigurations
- Phenomenon: Tool calls wait more than 3 seconds on the first attempt, with normal response speeds for subsequent calls. Cause: The plugin needs to load multi-source policy indexes on the first call, and the lack of a preloading mechanism causes cold start delay.
- Phenomenon: The tool call returns the
400 InternalError.Algo.InvalidParameter: The tool call ierror. Cause: The parameter format offunctionCallwas not specified correctly, and required retrieval condition fields are missing. - Phenomenon: Retrieval results include revoked policy documents. Cause: Regular refresh of data source indexes was not configured, and the plugin is calling outdated policy data.
How to confirm proper configuration
- Initiate a test conversation with a specific supervision policy retrieval requirement, and check whether the tool calling log displays the correct data source and parameter configuration.
- Check that the configurations of
toolChoiceandfunctionCallcomply with the syntax requirements of FastGPT v4.17.0, with no syntax errors. - Initiate first and subsequent tool calls, compare response times, and confirm that cold start delays meet expectations.
- Retrieve policy documents that include effective dates, confirm that results are filtered by date, with no outdated content included.
