The Minimum Viable AI Agent: Why You Should Start With Three Files

Most teams build too much before they understand what their AI agent actually does well. They add tools before testing identity. They build integrations before validating memory. They automate workflows before the agent has proven it can handle a single task reliably. The result: a complex system that fails in complex ways. The Minimum Viable Agent Here is everything a production-ready AI agent actually needs to start: SOUL.md — identity, scope, and constraints MEMORY.md — curated long-term context current-task.json — active task state That is it. Three files. No tools required for the concept to work. No integrations. No automation scaffolding. Why This Works These three files solve the three root causes of agent failure: Drift is solved by SOUL.md. When the agent reloads its identity every turn, it cannot gradually shift away from its original purpose. The file is the anchor. Amnesia is solved by MEMORY.md. Between sessions, the agent loses its working context. A curated memory file
