What I Learned Building a Multi-Agent AI System (That No Tutorial Warned Me About)
This article details the author's journey building Wizard Ecosystem, a multi-agent AI platform with roles for coder, writer, reviewer, etc. Key challenges included agents overriding constraints, orchestrator complexity, memory causing false continuity, and prompt engineering proving insufficient. The author reworked the system with centralized orchestration, strict schema-based I/O, validation steps, and limited memory usage. Broader implications: multi-agent systems require robust architectural design, not just clever prompts, to manage emergent chaos.

Summary
TL;DR
- Agents introduced logic errors and overrode orchestrator constraints.
- Orchestrator became the hardest component to design correctly.
- Memory is active bias injection, not neutral storage.
- Prompt engineering is a configuration layer, not system design.
- Centralized orchestration and strict schemas improved control.
- Timing consistency matters more than raw model quality.
- Multi-agent systems are about controlling chaos between agents.
Interesting facts
- The reviewer agent contradicted both coder and writer instead of fixing issues.
