What the data for this category looks like
Coke data is sourced primarily from the China Coking Industry Association, coastal port spot trading platforms, and the Dalian Commodity Exchange. Two update cadences apply: spot price and inventory data is updated daily, while futures contract quotes are pushed in real time. Standard document structure includes the following fields: origin identifier, delivery grade (for example, primary metallurgical coke), core test indicators (sulfur content, ash content, volatile matter), benchmark transaction price (unit: yuan/ton), regional logistics costs, and downstream steel mill procurement volume forecast.
What constraints these characteristics impose on tool calling and plugins
Different data sources use inconsistent field names. For example, some platforms label "benchmark transaction price" as "spot average price". Predefined field mapping rules must be set during tool calling to prevent parsing failures. Real-time quote push delay must be maintained within a reasonable range. Timeout thresholds must be configured for tool call nodes to prevent marketing content delays caused by waiting for outdated data. Delivery grade and test indicators are core validation items for the coke category. Plugins must enforce mandatory validation of required field completeness. Generated marketing content will not meet industry compliance requirements if this validation is missing. Dynamic fluctuations in regional logistics costs require tools to pull the latest regional data during calls. This avoids disconnects between quoted prices and actual costs.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_call_timeout | 120–180 seconds | Average time to pull coke spot and futures data is 90–150 seconds, with reasonable buffer to avoid timeout failures |
knowledge_base_recall_top_k | Top 3–5 entries | Coke marketing content should focus on regional supply and demand and core quoted prices. Excessive recall will distract target audiences |
field_mapping_template | 3 preset industry standard mappings | Significant differences exist in the naming of price and grade fields across different data sources. Preset templates enable rapid data alignment |
required_field_check | Enabled | Coke delivery grade and benchmark price are industry compliance required items. Validation prevents generation of invalid content |
plugin_trigger_interval | ≥ 86400 seconds | Spot and inventory data is updated daily. High-frequency calls cannot obtain updated content and consume additional resources |
model_tool_choice | auto | Must automatically determine whether to call tools based on user queries. Forced calls will increase meaningless API requests |
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 errors
- Phenomenon: After enabling the tool call node, knowledge base recall results are empty, or knowledge base queries cannot be triggered. Cause: Incorrect execution order configuration for tool calling and knowledge base recall. When tool calling runs first, it overwrites the knowledge base's call permissions.
- Phenomenon: Two separate thought process texts appear in the tool call debug log. Cause: The automatic retry switch for tool calling is not disabled, or the large model outputs two tool call instructions in a single generation.
- Phenomenon: Quoted coke prices in generated marketing content deviate significantly from actual daily market prices. Cause: No field validation rules are configured, and price data from non-benchmark delivery grades is mistakenly used as the quotation basis.
How to confirm correct configuration
- Manually trigger the tool call node, and verify that returned coke data fields match the preset mapping rules.
- Enable node debug mode, and check the number of tool call requests in logs to confirm no duplicate trigger records.
- Input test data missing core fields such as delivery grade, and confirm that the node triggers field validation prompts.
- Check plugin call duration logs, and adjust the
tool_call_timeoutparameter to match the actual data pull duration.
