Devin
Devin, Cognition's autonomous software engineer, and the operational questions that come with handing an agent a long-running task. These pages cover sessions and knowledge, cost and scope control, review of what Devin produced, and comparisons with other coding agents. Storage recurs because autonomous runs generate artifacts, logs, and drafts that need a home outside the session, and because a human reviewer needs to reach them without opening the agent.
Coverage includes what to hand Devin and what to keep for yourself, how to scope a session so it finishes rather than wandering, how consumption behaves in practice, and what a useful review of autonomous work looks like. Comparisons with other agents stay concrete about task types rather than ranking overall, because the difference shows up in specific work and disappears in aggregate.
