Implementation Reference
- The core handler logic for the 'delete_metadata' tool, which invokes the underlying deleteMetadata method on the knowledge graph manager and formats the success response.
case "delete_metadata": await this.knowledgeGraphManager.deleteMetadata(args.deletions); return formatToolResponse({ actionTaken: "Deleted metadata from nodes" }); - Defines the tool metadata including name, description, and input schema validation for the deletions parameter.
{ name: "delete_metadata", description: "Delete specific metadata from nodes in the knowledge graph", inputSchema: { type: "object", properties: { deletions: { type: "array", description: "Array of metadata deletions", items: { type: "object", description: "Metadata deletion", properties: { nodeName: {type: "string", description: "The name of the node containing the metadata"}, metadata: { type: "array", items: {type: "string", description: "Metadata item to delete"}, description: "An array of metadata to delete" }, }, required: ["nodeName", "metadata"], }, }, }, required: ["deletions"], }, } - src/integration/tools/registry/toolsRegistry.ts:42-45 (registration)Registers all static tools (including delete_metadata from staticTools.ts) into the central ToolsRegistry map during initialization.
