### AI overview

The article argues that A2A standardizes communication between agents but leaves the underlying data and state layer undefined. It contrasts A2A's horizontal agent-to-agent communication with MCP's vertical connection between an agent and external tools or data, and argues that production systems need both alongside a database-centered state architecture. AGENTS.md is presented as another interface standard that leaves durable state outside its scope.

### AI overview

A practical guide to designing multi-agent systems for platform engineering. It compares supervisor, pipeline, fan-out, hierarchical, and swarm patterns; explains how agent contracts, identity boundaries, audit trails, and verification address common failure modes; and distinguishes MCP from A2A.

### Source excerpt

Studies of real agent systems put failure rates between 41 and 86 percent, and almost none of it is the model's fault. Here are the patterns that hold up for platform work, and the discipline that decides whether yours does.
