LangChain's Managed Deep Agents Face Their First Real Decisions
LangChain shipped three deep-agent updates in two days that all point at the same unsexy problem (browser access, deployment location, and context budget are the actual blockers to production agents, not model quality), while Figma's PM team showed what "AI-native product org" looks like in practice with a 31-skill internal repo and an agent that runs growth experiments on its own.
