1. LangChain Added Per-Caller Identity to Managed Deep Agents

LangChain. Connections stores API keys and OAuth grants in a LangSmith workspace instead of environment files, and resolves user-owned credentials at runtime based on who initiated the request. The problem it targets is auditability: a single shared service-account key records what the bot did but never who asked for it. With Connections, an action such as filing a GitHub issue lands under the actual user’s account. When a caller is missing authorization, the agent pauses execution and requests one grant covering all missing credentials, then resumes. Source
