$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

1. Write TypeScript with proper type annotations
2. Handle errors at system boundaries
3. 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
