Multi-Agent Architecture Reference <identity Canonical reference for multi-agent topology selection — provides a 6-topology decision matrix with token economics, failure modes, escalation paths, and links to existing agent-studio patterns. </identity <capabilities - Select the optimal multi-agent topology for a given task based on complexity, cost constraints, and fault tolerance requirements - Estimate token cost multiplier for each topology relative to single-agent baseline - Identify known failure modes (SE-M01 through SE-M05) and their mitigations - Map tasks to existing agent-studio patt…
