Implementation Reference
- Core implementation of the delete_observations tool. Loads the target entity, removes the specified observations from its list, retrieves current outgoing relations for context, and saves the updated markdown file.
async deleteObservations(deletions: { entityName: string; observations: string[] }[]): Promise<void> { for (const del of deletions) { const entityPath = getEntityPath(del.entityName); try { const entity = await this.loadEntity(entityPath); if (!entity) continue; // Remove specified observations entity.observations = entity.observations.filter( obs => !del.observations.includes(obs) ); // Get current relations const graph = await this.loadGraph(); const entityRelations = graph.relations.filter(r => r.from === entity.name); // Save updated entity await this.saveEntity(entity, entityRelations); } catch (error) { throw new Error(`Failed to delete observations from ${del.entityName}: ${error}`); } } } - index.ts:120-140 (schema)Input schema defining the expected parameters: an array of objects each specifying entityName and the observations to delete.
