Agents go mainstream as the rules tighten

As agents moved into real products, oversight caught up. LangChain's Deep Agents v0.7 cut input-token use by 65% through harness optimization, and Cekura ($30/month) added diagnosis and monitoring for autonomous agents in production — evidence the tooling around agents is maturing fast.

On the policy side, U.S. review gates, a deepfake law, and agent-disclosure pressure all added friction before launch. The simple planning takeaway for the rest of 2026: watch cost control, agent safety, and vendor choice.
