Tool Calling and Plugins for Shipping Port Marketing Content

What the data for this category looks like

Core data for shipping ports comes from port operations management systems, vessel scheduling platforms, customs declaration interfaces, and berth reservation systems. Data update cadence has multiple tiers: vessel dynamics and berth occupancy status are updated minute-by-minute, cargo volume statistics and route quotes are updated hourly, and marketing lead data is synced in real time. Each data entry includes fields such as port code, in-port vessel IMO number, current cargo type, estimated departure time, and contact information of reserved customers. Units uniformly use TEU, hours, and ISO8601 format timestamps. Structured documents are mostly in CSV or Excel format, with multiple standardized business columns.

What constraints these characteristics impose on tool calling and plugins

High real-time requirements for dynamic data mean tool calls must support low-latency retrieval to avoid outdated marketing content caused by expired cache. Requirements for multiple standardized fields and units mean tool plugins must enforce matching of preset field names and unit formats during parameter verification, preventing generation of marketing copy that does not meet business specifications. Parsing long-text structured documents requires adapting to segment rules to preserve business logic integrity, avoiding splitting that breaks association information between cargo types and routes. Marketing content needs to combine multi-dimensional data, meaning tool calls must support batch retrieval of associated data for berths, vessels and customer leads; single-dimensional queries alone cannot meet requirements.

How to set configurations

Configuration Item	Recommended Value	Rationale
`tool_call_timeout`	`300 seconds`	Real-time port data retrieval typically takes 120-240 seconds; reserve sufficient redundancy to cover interface latency fluctuations
`max_tool_result_chars`	`8000 characters`	A single tool call result needs to include associated information for multiple vessels and berths; excessive truncation will damage business logic
`required_tool_fields`	`["port_code", "vessel_imo", "estimated_departure", "cargo_type"]`	Marketing content must accurately match port, vessel, sailing schedule and cargo type information required by customers; enforce verification of required fields
`file_parse_chunk_size`	`1000–1200 characters`	Port marketing documents mostly contain long-text route descriptions and cargo introductions; this range preserves business association integrity
`workflow_input_schema`	`Map to port business fields`	Align uploaded marketing material parameters with port system fields to ensure the workflow can properly receive business data
`tool_cache_ttl`	`60 seconds`	Port dynamic data updates frequently; overly long cache duration will cause marketing content to not match real-time status

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing.

Three Common Errors

Tool calls bound to workflows display empty file links when uploaded. This occurs because no mapping rule for the file_url field is configured in workflow_input_schema, causing the workflow to fail to receive incoming file parameters.
The number of tool call return results does not match expectations. This occurs because the max_tool_result_chars parameter is not set, leading to excessive truncation of results, or the required_tool_fields parameter is not specified to filter redundant data.
Parameter format errors are returned when calling port data tools. This occurs because the tool's unit verification function is not enabled, causing the incoming cargo volume unit to not use the preset TEU format, which does not meet business field requirements.

How to Confirm Configurations Are Properly Set

Trigger a tool call, check if the returned result fields include the configured required_tool_fields and that units comply with preset business standards.
Upload a port marketing document, verify that the parsed text segment length falls within the file_parse_chunk_size range.
Simulate uploading a file and call the bound workflow, check if the workflow can receive complete file link parameters.
Trigger tool calls three times consecutively, check if the update time of the returned results is within the tool_cache_ttl range, with no outdated content caused by cache expiration.
