Problem Statement
"Multi-agent systems left to unconstrained LLM planning develop deadlocks, infinite loop delegation, and context bloat. System stability demands deterministic state machine wrappers."
Section 2 Excerpt: Deterministic Guardrail Wrapper Specification
Enclose every agent tool call in a schema-validation middleware layer. If an agent outputs tool parameters violating the JSON Schema specification, intercept execution immediately and feed a structured error message back to the agent without executing the tool.
Implement a max-iteration counter (default: 5 turns) for any sub-agent delegation. If an agent fails to reach terminal state within 5 turns, trigger an automated fallback to human review.
Agent Topology Tradeoffs
| Topology | Max Complexity | Debugging Ease | Failure Isolation |
|---|---|---|---|
| Sequential Pipeline | Low | Very High | High |
| Supervisor Router | Moderate | High | Moderate |
| Autonomous Network | High | Low | Poor |
