Key point

The framework requires agents to live in Slack, handle identity via on-behalf-of or fixed credentials, use scoped memory, execute code in sandboxes, and run scheduled background tasks.

Details

  • LangChain built three internal agents (GTM Agent, OpenSWE, and Content Studio) that changed how marketing, sales, and engineering teams work by solving multiplayer harness problems.
  • The five core primitives are: living in Slack, handling identity (on-behalf-of vs. fixed credentials), maintaining global and user-level memory, executing code in sandboxes with secret proxies, and running scheduled or event-triggered background tasks.
  • Identity handling varies by agent: OpenSWE acts on behalf of the user for PRs but uses its own identity for background code review; GTM Agent uses fixed credentials for Salesforce but on-behalf-of for email (DMs only); Content Studio uses on-behalf-of for Notion but fixed credentials for Twitter (whitelisted users only).
  • All agents are built on Managed Deep Agents, which sits on top of the open source Deep Agents harness and provides infrastructure for channels, crons, sandboxes, memory, and identity.
