LangChain published Restock, a sample Slack-based purchasing agent built on Managed Deep Agents

It searches products and prepares a cart through Zinc, then pauses for human review in Slack and a separate Link payment approval. LangChain says the model does not handle payment secrets; the payment credential is kept in a private sandbox file and deleted after use. In the illustrated pen order, the user approved $23, the final charge was $22.18, and $0.82 was refunded. The post says a hosted deployment completed an end-to-end live order. The approach depends on merchant APIs that support MPP; it does not demonstrate general-purpose purchasing across arbitrary retailers.
