Teams building multi‑agent systems are converging on event‑driven, framework‑agnostic architectures with explicit graphs and first‑class observability.

A roundup of recent practice points in the same direction: use graph/state‑machine orchestration like LangGraph, expose agents behind a clean API boundary (FastAPI works), and keep routing deterministic and observable. Debugging starts with evidence, not vibes: capture schema‑validated tool args, results, and failure paths as shown in this hands‑on build and trace guide example.

Don’t let a framework leak into your architecture. Keep providers and pipelines pluggable, and put a log or pub/sub in the middle so agents publish and subscribe instead of calling each other directly (why this matters, ops perspective). For platform support, API‑centric offerings like the OpenAI Agents SDK and Mistral’s agents API give you tool use, handoffs, and tracing blocks, but they’re parts—not your architecture context.
