Implementation Reference
- src/index.ts:1200-1210 (handler)Handler for dhis2_optimize_performance tool: receives arguments, calls generatePerformanceOptimizations helper, and returns markdown response.
case 'dhis2_optimize_performance': const perfArgs = args as any; const perfOptimizations = generatePerformanceOptimizations(perfArgs); return { content: [ { type: 'text', text: perfOptimizations, }, ], }; - src/debugging-helpers.ts:1155-1250 (helper)Core helper function that generates comprehensive performance optimization recommendations including strategies, code examples, metrics analysis, and DHIS2-specific optimizations.
