The shared brain pattern gives every AI agent an organisation runs access to the same knowledge base, so context does not die with the tool that learned it. Work through a problem with one agent in the morning and a different agent in the afternoon picks up where the first left off, because notes, tasks, and decisions live in a shared store instead of inside each harness. AI engineer Sajal Sharma demonstrated the setup on O'Reilly's Zero to Agent in 30 Minutes: a personal knowledge base acting as a shared workspace for all his agents, where a task added on one tool shows up for all the others.

The pattern is spreading from personal setups into product: LangChain released OpenWiki, which generates and maintains repository documentation that both people and coding agents can use, and Garry Tan open-sourced GBrain, a memory layer for agents built on the same principle. OpenWiki GBrain
