10 Agent Architecture Blueprints

10 complete agent architecture blueprints, each with detailed descriptions, ASCII flow diagrams, Python code skeletons, implementation notes, and real-world use cases. Architectures included: 1. ReAct (Reason + Act) — Interleaved reasoning and action 2. Chain-of-Thought (CoT) — Step-by-step reasoning chains 3. Tree-of-Thoughts (ToT) — Branching exploration of solutions 4. Multi-Agent Orchestrator — Coordinating multiple specialized agents 5. Tool-Using Agent — Function calling and tool integration 6. RAG Agent — Retrieval-augmented generation pipeline 7. Plan-and-Execute — Strategic planning with tactical execution 8. Reflexion Agent — Self-reflecting and self-improving 9. AutoGPT-style Autonomous Agent — Goal-driven autonomous operation 10. Human-in-the-Loop Agent — Collaborative human-AI workflow Each blueprint includes: • Detailed architecture description • ASCII flow diagram • Python code skeleton (30+ lines) • Implementation notes and best practices • Pros, cons, and ideal use cases • Complexity rating and recommended tools
