We Built a Slack-to-GitHub PR Agent in a Few Lines of Code

LangChain's Ishaan Lal demos Patch, an agent triggered from Slack that writes and opens GitHub PRs on command. Patch reads and writes to GitHub through the GitHub MCP and runs its own code in a sandbox before shipping a PR, all from a single Slack message. Ishaan then walks through how Patch is built with Managed Deep Agents, wiring up Slack, GitHub, and a sandbox in just a few lines of code.
