Implementation Reference
- index.ts:205-221 (handler)The core handler function in KnowledgeGraphManager that deletes specified relations by filtering them out from the graph's relations array and saving the updated graph to the memory file.
async deleteRelations( relations: Relation[], filepath: string ): Promise<void> { await this.setMemoryFilePath(filepath); const graph = await this.loadGraph(); graph.relations = graph.relations.filter( (r) => !relations.some( (delRelation) => r.from === delRelation.from && r.to === delRelation.to && r.relationType === delRelation.relationType ) ); await this.saveGraph(graph); } - index.ts:488-525 (schema)The input schema definition for the delete_relations tool, specifying the expected parameters: an array of relations (each with from, to, relationType) and memoryFilePath.
