Multi-agent systems promise autonomous problem-solving, but production deployments require careful orchestration, guardrails, and observability.

Agent Architecture Patterns
- Supervisor: one agent delegates to specialists
- Debate: agents argue opposing views, judge selects
- Pipeline: sequential handoffs with validation gates
Tool Use and Memory
agent = Agent(
tools=[search, calculator, code_executor],
memory=ConversationBuffer(window=10),
max_iterations=5,
)
Limit tool calls and iterations to prevent runaway loops.
Human-in-the-Loop
Require approval for destructive actions: database writes, external API calls, financial transactions.
Failure Modes
- Infinite loops between agents
- Hallucinated tool outputs propagated unchecked
- Cost explosions from unbounded agent chains
Summary
Start with single-agent + tools. Add multi-agent complexity only when a clear orchestration benefit exists.
