How to Use This Catalog

1. Identify the Problem

Start with the problem you're solving — coordination, reliability, learning, etc. Browse groups below to find the right category.

2. Compare Patterns

Each pattern has Intent, Structure, Pros/Cons, and code examples. Compare similar patterns within a group to pick the best fit.

3. Study the Code

Click into any pattern for full Python (autogen) and C# implementations, architecture diagrams, and real-world scenarios.

4. Combine Patterns

Most real systems use multiple patterns together. Check "Related Patterns" on each page to discover complementary designs.

About This Catalog

This catalog documents 45 multi-agent architectural patterns drawn from classic distributed AI research, Gang-of-Four design principles, and modern LLM orchestration practices (Autogen, LangGraph, CrewAI). Each pattern page includes architecture diagrams, working Python and C# code, trade-off analysis, and real-world applicability guidance.
