Parallel coding agents with tmux and Markdown specs
Summary
The article describes a lightweight setup for running 4–8 parallel coding agents using tmux, Markdown-based feature design specs, and a set of slash commands. It explains how to structure work with Planner, Worker, and PM roles, manage feature designs (FDs) through a lifecycle of planned, design, open, in progress, verification, complete, and more, and outlines the development loop from exploration to verification. It also discusses navigation between contexts, hard limits (cognitive load and context windows), and practical tooling considerations like aliases and idle indicators to manage multiple agents efficiently.
