Implementation Reference
- index.ts:799-816 (handler)The main handler function in KnowledgeGraphManager that executes the find_similar_errors tool logic by filtering and sorting lesson entities based on similarity to the provided error pattern.
async findSimilarErrors(errorPattern: ErrorPattern): Promise<LessonEntity[]> { const graph = await this.loadGraph(); return graph.entities .filter((e): e is LessonEntity => { if (e.entityType !== 'lesson') return false; const lessonEntity = e as Partial<LessonEntity>; return ( lessonEntity.errorPattern !== undefined && ( lessonEntity.errorPattern.type === errorPattern.type || lessonEntity.errorPattern.message.toLowerCase().includes(errorPattern.message.toLowerCase()) || lessonEntity.errorPattern.context === errorPattern.context ) ); }) .sort((a, b) => (b.metadata?.successRate ?? 0) - (a.metadata?.successRate ?? 0)); } - index.ts:1166-1184 (registration)Tool registration in the ListTools response, including name, description, and input schema.
