How the channel uses _the lengthening leash_ In this channel's material on AI coding agents, the lengthening leash describes the steadily expanding scope of autonomous work that agents like Cognition's Devin can take on: as the underlying models improve, each agent can be trusted to run longer and further before a human needs to step in[^e8655330@0]. The phrase frames agent progress as a gradual widening of autonomy rather than a single jump to full independence — the leash stays attached, but it gets longer over time.
