Why Multitasking With AI Coding Agents Breaks Down (And How I Fixed It)

AI coding agents are starting to feel like teammates. You ask one to refactor a module. Another to write tests. A third to prototype a feature. Individually, they’re powerful. But the moment you try to run them in parallel, things get messy. This article is about why that happens — and what I learned trying to fix it. The Multitasking Problem Running one AI coding session is simple. Running three at the same time usually looks like this: Three terminal windows Multiple feature branches Manual context switching No clear overview of what each agent is doing Technically, it works. Cognitively, it doesn’t scale. The friction appears in small ways: You forget which terminal is working on which branch. You accidentally reuse context. You lose track of long-running operations. You hesitate to spin up “just one more” agent because overhead increases. The CLI gives you power — but no structure. Why tmux (Alone) Isn’t Enough You can improve layout with tools like tmux . That helps visually. But
