What the Data for This Category Looks Like
Data sources include interaction tracking points and user trigger behavior records from terminal systems. Updates occur immediately upon triggering. The document structure includes fields such as trigger timestamp, terminal device ID, user search text, search result count, and search time consumption.
Field formats are fixed. trigger_timestamp is an integer type, unit milliseconds. query_text is a string type, unit characters. result_count is an integer type, unit entries. device_id is a unique identifier string. No additional aggregation processing is performed on the data. Data is directly synchronized to the tool calling link.
Constraints Imposed on Tool Calling and Plugins By These Characteristics
The real-time update feature requires the tool calling link to have low-latency processing capabilities. User interaction interruptions caused by waiting timeouts must be avoided.
The fixed field format requires plugins to use strictly matching parsing strategies. This prevents data loss caused by deviations in field formats.
Raw data with no additional aggregation processing requires tool calling to directly connect to the raw data interface. It cannot rely on format conversion from intermediate layers.
Differences in input length in terminal scenarios require tool calling to adapt to variable-length search text. A reasonable length threshold must be configured.
The uniqueness of the device ID requires plugins to be compatible with ID formats of different terminals. Parsing errors during cross-terminal deployment are avoided.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
TOOL_CALL_TIMEOUT | 3000 milliseconds | Matches the low-latency requirements of in-terminal interactions, avoids timeout interruptions of user operations |
MAX_QUERY_CHAR_LENGTH | 1800–2200 characters | Adapts to the default length limit of terminal input boxes, covers most natural language search scenarios |
PLUGIN_TRIGGER_CONDITION | on_user_query_submit | Matches the trigger logic of in-terminal natural language search, aligns with user interaction paths |
FIELD_PARSE_STRATEGY | exact_match | Adapts to the fixed format of terminal data fields, reduces parsing deviations |
MAX_TOOL_CALL_STEPS | 3 steps | Avoids user waiting caused by overly long tool calling chains in terminal scenarios |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: A
Your model may not support tool_callerror is returned when calling a tool. Cause: A large language model that supports tool calling was not selected, or the tool calling switch was not enabled in the model configuration. - Symptom: Associated plugins fail to load after exporting a workflow and importing it to another environment. Cause: The dependency configuration identifiers of the plugins were not carried synchronously when exporting the workflow. Plugin resources were not synchronously deployed during cross-environment deployment.
- Symptom: The number of results returned by tool calling does not match the actual number of results returned by the terminal search. Cause: Field mapping rules were not configured correctly. The
result_countfield in terminal data was not correctly bound to the result count parameter of tool calling.
How to Verify Configuration Is Complete
- Initiate a terminal search request that conforms to the configured length. Check whether a complete tool calling chain record is generated in the system log.
- Submit search text that exceeds the
MAX_QUERY_CHAR_LENGTHlimit. Verify whether the interface returns a valid length exceedance prompt. - Export the current workflow and import it to a test environment. Confirm that all associated plugins are displayed normally and can be called normally.
- Trigger tool calling multiple times. Verify that the returned result fields fully match the configured mapping rules.
