Long-form architectural teardowns and reference notes on the agentic stack.
Three architectural framings are competing for the same agentic-systems problem. Each gets something right. Each papers over something important. A reading of the OS metaphor, Nate Jones's Mesh thesis, and the Workforce model that Anthropic and Sierra have leaned into.
Identity is the problem the agentic field has spent the least time on and the one that determines whether the systems are deployable in any regulated environment. A working framework for what identity actually has to do.
A reading of four bundled agentic platforms — Sema4.ai, MultiOn, Adept's ACT family, and Web4OS — and the architectural patterns that recur across them: supervisor topologies, card-stream surfaces, credit schedulers, and canonical-host integrations.
Most products labeled 'agentic OS' are orchestration libraries with a marketing budget. A working definition, drawn from the parts of the stack that actually have to behave like an operating system.
