Execution model
A useful multi-agent system is not a chat room. It is a runtime with bounded roles, typed handoffs, termination rules, and inspectable state transitions.
Multi-Agent Systems
Architecture patterns for coordinating multiple AI agents with clear roles, shared state, tools, and failure handling.

Reliability model
The hard work is retries, delegation limits, typed tool failures, observability, and recovery after partial execution.
Multi-Agent Runtime
Coordination, state transitions, and typed execution boundaries for agents that need to work together.

Tool Ecosystem
MCP integrations, typed tools, permission boundaries, routing schemas, and protocol adapters.

Evaluation Systems
Regression suites, adversarial cases, trace review, cost tracking, and evidence that a system is ready to ship.
