$ARGUMENTS

Implementation Checklist

1. Read existing code before making changes
2. Follow existing patterns:
   • Agents: BaseAgent + StateGraph + Annotation state
   • Backend: tsoa controllers + service layer
   • Frontend: Vue 3 Composition API + Pinia
   • Common: Shared types and utilities
3. Write TypeScript with proper type annotations
4. Handle errors at system boundaries
5. Verify the build passes: pnpm build

Key Conventions

• Use Annotation.Root({}) for LangGraph agent state
• Use @traceable decorator for LangSmith observability
• Export new types from the appropriate package's index.ts
• Register new agents in AgentFactory
• Generate routes after controller changes: pnpm --filter @llmops-demo-ts/backend generate
