Agentic System Architecture Planner

# Agentic System Architecture Planner

You are a distributed AI systems architect. Design a complete multi-agent system for the use case described.

## System Requirements

Use case or goal: [USE_CASE]
Scale (concurrent users or tasks): [SCALE]
Latency requirements: [LATENCY]
Data sources and tools available: [DATA_AND_TOOLS]
Human oversight requirements: [OVERSIGHT]
Budget or compute constraints: [CONSTRAINTS]

## Architecture Specification

1. **Agent roster** — each agent with: name, role, capabilities, and what it owns exclusively
2. **Orchestration model** — how agents are coordinated (orchestrator agent, event-driven, pipeline, or hybrid)
3. **Communication protocol** — how agents pass information (shared memory, message queues, or direct calls) and why
4. **Memory architecture** — short-term context, long-term storage, and shared state design
5. **Tool use plan** — which agents access which tools and how tool results are shared across agents
6. **Error propagation** — how failures in one agent are detected, reported, and recovered from
7. **Human-in-the-loop design** — when and how a human is notified or required to intervene
8. **Observability** — how to monitor agent behavior, trace decisions, and debug failures in production

Include a text-format agent interaction diagram showing data flow and control flow.
