Implementation Reference
- index.ts:645-654 (handler)The core handler function that implements the delete_observations tool logic. It loads the knowledge graph, removes the specified observations from the matching entities by filtering them out, and saves the updated graph.
async deleteObservations(deletions: { entityName: string; observations: string[] }[]): Promise<void> { const graph = await this.loadGraph(); deletions.forEach(d => { const entity = graph.entities.find(e => e.name === d.entityName); if (entity) { entity.observations = entity.observations.filter(o => !d.observations.includes(o)); } }); await this.saveGraph(graph); } - index.ts:1014-1038 (schema)The input schema definition for the delete_observations tool, specifying the expected structure of the deletions parameter as an array of objects with entityName and observations.
{ name: "delete_observations", description: "Delete specific observations from entities in the knowledge graph", inputSchema: { type: "object", properties: { deletions: { type: "array", items: { type: "object", properties: { entityName: { type: "string", description: "The name of the entity containing the observations" }, observations: { type: "array", items: { type: "string" }, description: "An array of observations to delete" }, }, required: ["entityName", "observations"], }, }, }, required: ["deletions"], }, }, - index.ts:1232-1234 (registration)The switch case in the CallToolRequest handler that registers and dispatches the delete_observations tool call to the KnowledgeGraphManager's deleteObservations method.
case "delete_observations": await knowledgeGraphManager.deleteObservations(args.deletions as { entityName: string; observations: string[] }[]); return { content: [{ type: "text", text: "Observations deleted successfully" }] };
