Multi-Agent Patterns

• ✓Build an orchestrator that plans at run time, delegates to specialist workers, and guards against a step no worker can do
• ✓Build a supervisor that routes, applies a quality gate, and escalates instead of looping
• ✓Compare a flat supervisor with a two-level hierarchy on the same tickets and read the cost of the extra level
• ✓Build a sequential pipeline that validates every hop, and see why shape checks alone let a wrong answer through
• ✓Run independent checks in parallel and merge them in code, including when one branch fails
• ✓Map one worker over many chunks, reduce in code or with a tree, and test a debate and its judge against known answers

Pick how several agents should be organised before you build them, and know the failure each arrangement brings - the decision that comes before every multi-agent system.
