The agent stack is splitting into platforms, runtimes and trust layers

A practical read on where AI agents are separating into durable categories - and what to watch before betting a workflow on the next shiny demo.

TL;DR

The agent market is becoming less about one assistant that does everything and more about a stack: orchestration, tool access, memory, permissions, evaluation, and human handoff.

What changed

The most useful systems are moving from chat-first demos to workflow-first infrastructure. The winners will be the tools that make state, trust, recovery and observability boring.

Why it matters

Teams should avoid choosing platforms only by model quality. The operational layer - auth, logs, rollback, permissions and review - determines whether agents survive real work.
