My AI Agents Talk to Each Other. Here's the Inter-Agent Communication Protocol

The author runs a solo company using AI agent departments (CEO, CFO, CTO, Lawyer, etc.) and found that the hardest part of multi-agent systems is not giving agents roles but making reliable handoffs between them. To solve inconsistent cross-domain consultation, they built an explicit inter-agent communication protocol with a trigger table that maps domain-crossing work to mandatory peer reviews, plus a standardized message format to prevent context loss during handoffs.
