AI Coding Agents Need a Team Runtime, Not Just More tmux

Getting agents to run is the easy part. Running agents under control is the hard part: knowing which server an agent sits on, what it's allowed to touch, who can watch a session, and who can drop into a teammate's session to help. This is a hands-on blueprint for exactly that: the jump from agents scattered across people's laptops to a managed, multi-developer runtime, built with nothing fancier than SSH, tmux, sudo, and infrastructure-as-code. Plenty of ready-made tools already cover the solo case. Agent Deck , AoE , Vibe Kanban , and the like spin up parallel agent sessions, sort them by project, and show status. Vendors are moving the same way too: Claude Code now has /agent-view . But those answer how one person runs a lot of agents, not how a team runs them safely. Concretely, a team needs to know where and how sessions get launched, what permissions agents run with, who can see them, who can attach to them, and how to give leads and seniors access to juniors' sessions for mentoring. It also needs a standardized execution environment and a way to scale the whole thing through infrastructure-as-code. Today I'll walk through how to build a basic agent runtime for teams of two or more: runtime / execution environment: where and how agents are launched; servers, permissions, management; workflow: how agents are used. Not the topic today. Maturity levels for team agent runtimes Before a team runtime appears, there are usually two personal modes: Level 0A, personal local mode: agents run on a laptop in a local terminal; Level 0B, personal server mode: durable sessions run on remote dev servers with tmux/zellij, /agent-view , Agent Deck, or similar tools. After that, the runtime becomes a team concern: Level 1, small team runtime:
