List work item types that can be related to a given work item type. Use this when setting up work item relationships to discover which types are valid for the chosen relationType.
AI agents call list_work_item_relation_work_item_types to retrieve information from Yunxiao without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
relationType | string | — | Relation type filter. Valid values: PARENT, SUB, ASSOCIATED, DEPEND_ON, DEPENDED_BY. Omit to list all compatible types. |
organizationId | string | — | Yunxiao organization ID. When omitted, the server uses the user's default organization. |
workItemTypeId | string | Yes | Work item type ID (numeric string). Use list_work_item_types to find available types. |
Parameters from the server's own tool schema.
This tool retrieves metadata about allowable work item type relationships. It performs a read-only query to enumerate valid relationship configurations without side effects. The action is informational and supports discovery, fitting the 'Read' category with low severity since misuse would only expose schema/metadata information.
From the tool's definition The tool 'lists' work item types and is explicitly described as 'discover[ing]' valid relationships—a query operation with no modification, deletion, or execution of external operations.
