The always-on agent is now officially the next front in the platform wars, and Anthropic arriving with a credible entry confirms this is no longer a niche experiment. The approval-gate design stands out to us — requiring confirmation before payments is exactly the trust architecture enterprises will demand before letting agents loose on inboxes and finances. Six thousand connectors is a serious integration play; plumbing and distribution, not raw model quality, may decide who wins this category. The open question is whether users actually want proactive agents — notification fatigue and unpredictable compute costs could sink the whole premise. It also marks Anthropic's shift from model lab to product company, a direct consumer collision with OpenAI. Reliability outside demos will be the real test.
