LangChain Deep Agents demo: drop a CSV in Slack, get a slide deck back
Hacubu · x · 2026-10-15
LangChain showed a practical workflow with Managed Deep Agents: drop a file like orders.csv into a Slack channel, and the agent processes it in an integrated Sandbox, iterates on the output, and sends back a PDF slide deck in the same thread.
The whole setup requires only a Slack channel, a Sandbox file, and an instructions.md specifying that outputs go under /workspace and get returned via attachfile. Wiring is done with channels.slack() and definesandbox() from the manageddeepagents package.
