How I Built a Multi-Agent Development System That Plans, Executes, and Remembers

Building software alone has a structural problem: context leaks between sessions, tasks drift, and knowledge disappears when you step away. This article walks through an architecture that solves it: a coordinator agent that orchestrates parallel sub-agents through structured research and planning stages, with all context persisted to flat files. The system runs autonomously - research, gap analysis, architecture, and verification commands all flow through stage gates without the human micromanaging each step. The result is a development workflow that's continuous, auditable, and doesn't require you to hold everything in your head.
