This Level 3 guide is for builders who already run coding agents daily and want to turn them into durable autonomous systems. You will learn how to design harnesses that run overnight, verify their own work with evidence, coordinate parallel agents safely, route models by task economics, and preserve memory without burying agents in context.
Who this is for: You already live in coding agents and want long autonomous loops that run overnight and finish a project without steering.
Long autonomous agent runs become reliable only when the harness, not the chat transcript, owns phase boundaries, state, verification, routing, and spend.
Read the deep diveLong-running agents become dependable when the loop is built around external evidence: explicit triggers, executable completion tests, review gates, proof artifacts, and hard stop conditions.
Read the deep diveParallel agents are only useful when each worker has isolated code and state, independent context, and a verification path that promotes one synthesized result instead of merging chaos.
Read the deep diveAgents do not need a bigger archive; they need a memory substrate that is small enough to load, structured enough to traverse, and durable enough to improve across runs.
Read the deep diveRoute models like compute in a distributed system: scarce frontier reasoning should sit on the critical path only where it changes the probability of task completion.
Read the deep diveMature agentic systems are not better prompts; they are small operating systems with routable entry points, durable state, verification loops, and controlled authority.
