Starting today, @LangChain’s Managed Deep Agents can bake your agent’s environment at deploy time. 🧑‍💻 No clone. No install. No repeated setup. Drop in setup.sh or a Dockerfile. Bake once. Every new thread starts ready. 👇

Starting today, a @LangChain's Managed Deep Agent deploy provisions your Slack app for you 🤯 No manifest. No OAuth redirects. No bot tokens to copy around. One command, and your agent says 👋 in Slack.

Agents are easy to demo locally. The hard part is shipping them inside a real app. We published a deployment cookbook for @LangChain agents: full-stack examples with streaming UI, subagents, thread history, and production persistence notes across common JS frameworks 🚀 🧵👇
