Patterns¶

These patterns represent battle-tested approaches to common multi-agent scenarios. Each pattern includes complete working code, use cases, and performance characteristics.

Available Patterns¶

Fan-Out/In¶

Distribute work to parallel agents, then synthesize results. Use for, Research, analysis, brainstorming

Sequential Analysis¶

Build understanding step-by-step through dependent operations. Use for, Document processing, complex reasoning

Conditional Flows¶

Execute different paths based on runtime conditions. Use for, Dynamic workflows, decision trees

ReAct with RAG¶

Combine reasoning with retrieval-augmented generation. Use for, Knowledge-intensive tasks

Tournament Validation¶

Multiple approaches compete, best solution wins. Use for, Quality-critical outputs

Pattern Selection Guide¶

def select_pattern(task):
    if task.needs_multiple_perspectives:
        return "fan-out-in"
    elif task.requires_step_by_step_building:
        return "sequential-analysis"
    elif task.has_conditional_logic:
        return "conditional-flows"
    elif task.needs_external_knowledge:
        return "react-with-rag"
    elif task.requires_best_quality:
        return "tournament-validation"
    else:
        return "simple-branch"

Common Combinations¶

Research Pipeline¶

Fan-Out (gather) → Sequential (analyze) → Fan-Out (verify)

Document Processing¶

Sequential (extract) → Conditional (classify) → Fan-Out (process by type)

Decision Making¶

Fan-Out (options) → Tournament (evaluate) → Sequential (implement)
