Anthropic introduces Managed Agents, a hosted service for long-horizon agent work built on stable interfaces that decouple from harness implementations. They argue harness assumptions become stale as models improve, citing context resets added for Sonnet 4.5's 'context anxiety' that proved unnecessary with Opus 4.5.

Firsthand engineering post from Anthropic with a concrete case of model improvement invalidating a prior harness workaround; useful architectural framing for agent builders.
