Implementation Reference
- index.ts:188-203 (handler)The handler function in KnowledgeGraphManager that deletes specific observations from the specified entities in the knowledge graph by loading the graph, filtering out the observations, and saving the updated graph.
async deleteObservations( deletions: { entityName: string; observations: string[] }[], filepath: string ): Promise<void> { await this.setMemoryFilePath(filepath); 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:455-487 (schema)Input schema definition for the delete_observations tool, specifying the structure of deletions array and memoryFilePath.
